Prerequisites ================ Here is the software you need to have around before you start installing CDS Invenio: a) Unix-like operating system. The main development and production platform for CDS Invenio at CERN is Debian GNU/Linux, but any Unix system supporting the software listed below should do. Note that localhost should have an MTA running so that CDS Invenio can email notification alerts or registration information to the end users, contact moderators and reviewers of submitted documents, inform administrators about various runtime system information, etc. Note that if you are using Debian "Sarge" GNU/Linux, you can install most of the prerequisites and recommendations listed below by running: $ sudo apt-get install libapache2-mod-python2.3 \ libapache2-mod-php4 apache2-mpm-prefork mysql-server \ mysql-client php4-cli php4-mysql python2.3-mysqldb \ python2.3-numeric python2.3-4suite python2.3-psyco rxp \ wml gnuplot xpdf-utils gs-common antiword catdoc wv \ html2text ppthtml xlhtml clisp sbcl cmucl gettext b) MySQL server (may be on a remote machine), and MySQL client (must be available locally too). MySQL versions 4.0.x are recommended, versions above 4.1.0 may cause troubles. Please set the variable ``max_allowed_packet'' in your ``my.cnf'' init file to at least 4M. c) Apache 2 server, with support for loading DSO modules, and optionally with SSL support for HTTPS-secure user authentication. Tested mainly with version 2.0.43 and above. Apache 2.x is required for the mod_python module (see below). Note for FreeBSD users: Thierry Thomas reports troubles with Python open() in the Apache 2 and mod_python context. The solution is either (1) to compile Apache 2 with --enable-threads (the port has a knob WITH_THREADS to do that); or (2) to add the two following two lines in Apache's envvars file: LD_PRELOAD=/usr/lib/libc_r.so # or libpthread.so export LD_PRELOAD d) Python v2.3 or above: as well as the following Python modules: - (mandatory) MySQLdb: - (mandatory) Numeric module (v21 and above): - (recommended) PyStemmer, for indexing and ranking: - (recommended) PyRXP, for very fast XML MARC processing: - (recommended) Gnuplot.Py, for producing graphs: - (optional) 4suite, slower alternative to PyRXP: - (optional) Psyco, to speed up the code at places: - (optional) RDFLib, to use RDF ontologies and thesauri: - (optional) mechanize, to run regression web tests: e) mod_python Apache module. Tested mainly with versions 3.0BETA4 and above. mod_python 3.x is required for Apache 2. Previous versions (as well as Apache 1 ones) exhibited some problems with MySQL connectivity in our experience. f) PHP compiled as Apache module, including MySQL support. Tested mainly with PHP version 4.3.0 and above. (Note that if you are compiling mod_php from source, it is good to compile it against the same MySQL client library as mod_python, so that the two Apache modules are using the same MySQL client library. We saw Apache/PHP/Python problems in the past when they weren't. A care should be taken even when you are using precompiled packages. For example, on Ubuntu 5.10 "Breezy Badger" it seems that python2.4-mysqldb depends on libmysqlclient14, while php5-mysql on libmysqlclient12, which leads to Apache segmentation faults.) g) PHP compiled as a standalone command-line executable (CLI) (in addition to Apache module) is required, too. As of PHP 4.3.0 you'll obtain the CLI executable by default, so you don't have to compile it separately. Note that PHP CLI should be compiled with the process control support (--enable-pcntl) and the compression library (--with-zlib). h) WML - Website META Language. Tested mainly with versions 2.0.8 and 2.0.9. Note that on Red Hat Linux 9 the WML 2.0.9 compiled with Perl 5.8.0 exhibits problems, so you better use downgraded/upgraded Perl for compiling WML on that platform. i) If you want to be able to extract references from PDF fulltext files, then you need to install pdftotext version 3 at least. j) If you want to be able to search for words in the fulltext files (i.e. to have fulltext indexing), then you need as well to install some of the following tools: - for PDF files: pdftotext or pstotext - for PostScript files: pstotext or ps2ascii - for MS Word files: antiword, catdoc, or wvText - for MS PowerPoint files: pptHtml and html2text - for MS Excel files: xlhtml and html2text k) If you have chosen to install fast XML MARC Python processors in the step d) above, then you have to install the parsers themselves: - (optional) RXP: - (optional) 4suite: l) (recommended) Gnuplot, the command-line driven interactive plotting program. It is used to display download and citation history graphs on the Detailed record pages on the web interface. Note that Gnuplot is not required, only recommended. m) (recommended) A Common Lisp implementation, such as CLISP, SBCL or CMUCL. It is used for the web server log analysing tool and the metadata checking program. Note that any of the three implementations CLISP, SBCL, or CMUCL will do. CMUCL produces fastest machine code, but it does not support UTF-8 yet. Pick up CLISP if you don't know what to do. Note that a Common Lisp implementation is not required, only recommended. n) GNU Gettext, a set of tools that makes it possible to translate the application in multiple languages. This is available by default on many systems. Note that the configure script checks whether you have all the prerequisite software installed and that it won't let you continue unless everything is in order. It also warns you if it cannot find some optional but recommended software. 1. Quick instructions for the impatient CDS Invenio admin ========================================================= $ cd /usr/local/src/ $ wget http://cdsware.cern.ch/download/cds-invenio-0.90.tar.gz $ wget http://cdsware.cern.ch/download/cds-invenio-0.90.tar.gz.md5 $ wget http://cdsware.cern.ch/download/cds-invenio-0.90.tar.gz.sig $ md5sum -v -c cds-invenio-0.90.tar.gz.md5 $ gpg --verify cds-invenio-0.90.tar.gz.sig cds-invenio-0.90.tar.gz $ tar xvfz cds-invenio-0.90.tar.gz $ cd cds-invenio-0.90 $ ./configure --prefix=/opt/cds-invenio \ --with-weburl=http://webserver.domain.com \ --with-sweburl=https://webserver.domain.com \ --with-dbhost=sqlserver.domain.com \ --with-dbname=cdsinvenio \ --with-dbuser=cdsinvenio \ --with-dbpass=myp1ss \ --with-python=/opt/python/bin/python2.3 $ vi ./config/config.wml ## optional, but strongly recommended $ make $ mysql -h sqlserver.domain.com -u root -p mysql mysql> CREATE DATABASE cdsinvenio; mysql> GRANT ALL PRIVILEGES ON cdsinvenio.* TO cdsinvenio@webserver.domain.com IDENTIFIED BY 'myp1ss'; $ sudo vi /path/to/apache/conf/httpd.conf ## see below in part 2 $ sudo vi /path/to/php/conf/php.ini ## see below in part 2 $ sudo /path/to/apache/bin/apachectl graceful $ make create-tables ## optional $ sudo ln -s /opt/cds-invenio/lib/python/invenio \ /usr/local/lib/python2.3/site-packages/invenio \ ## optional $ make install $ make test ## optional $ sudo chown -R www-data /opt/cds-invenio/var $ make create-demo-site ## optional $ make load-demo-records ## optional $ make remove-demo-records ## optional $ make drop-demo-site ## optional $ firefox http://webserver.domain.com/admin/ ## optional 2. Detailed instructions for the patient CDS Invenio admin ========================================================== The CDS Invenio uses standard GNU autoconf method to build and install its files. This means that you proceed as follows: $ cd /usr/local/src/ Change to a directory where we will configure and build the CDS Invenio. (The built files will be installed into different "target" directories later.) $ wget http://cdsware.cern.ch/download/cds-invenio-0.90.tar.gz $ wget http://cdsware.cern.ch/download/cds-invenio-0.90.tar.gz.md5 $ wget http://cdsware.cern.ch/download/cds-invenio-0.90.tar.gz.sig Fetch CDS Invenio source tarball from the CDS Software Consortium distribution server, together with MD5 checksum and GnuPG cryptographic signature files useful for verifying the integrity of the tarball. $ md5sum -v -c cds-invenio-0.90.tar.gz.md5 Verify MD5 checksum. $ gpg --verify cds-invenio-0.90.tar.gz.sig cds-invenio-0.90.tar.gz Verify GnuPG cryptographic signature. Note that you may first have to import my public key into your keyring, if you haven't done that already: $ gpg --keyserver wwwkeys.pgp.net --recv-keys 0xBA5A2B67 The output of the gpg --verify command should then read: Good signature from "Tibor Simko " You can safely ignore any trusted signature certification warning that may follow after the signature has been successfully verified. $ tar xvfz cds-invenio-0.90.tar.gz Untar the distribution tarball. $ cd cds-invenio-0.90 Go to the source directory. $ ./configure --prefix=/opt/cds-invenio \ --with-weburl=http://webserver.domain.com \ --with-sweburl=https://webserver.domain.com \ --with-dbhost=sqlserver.domain.com \ --with-dbname=cdsinvenio \ --with-dbuser=cdsinvenio \ --with-dbpass=myp1ss \ --with-python=/opt/python/bin/python2.3 Configure essential CDS Invenio parameters, with the following signification: --prefix=/opt/cds-invenio CDS Invenio general installation directory, used to hold command-line binaries and program libraries containing the core CDS Invenio functionality, but also to store web pages, runtime log and cache information. Several subdirs like `bin', `lib', and `var' will be created inside the --prefix directory to this effect. Note that the --prefix directory should be chosen outside of the Apache htdocs tree, since only one subdirectory (prefix/var/www) is to be accessible directly on the Web (see below). --with-weburl=http://webserver.domain.com The URL denoting the home URL of your CDS Invenio installation. The files served by this URL will be located in `prefix/var/www', so later on in your Apache config file you would map `weburl' to `prefix/var/www' (see below). --with-sweburl=https://webserver.domain.com The URL denoting the HTTPS-secure equivalent of the home URL. The secure home URL will be used for personalization pages, such as user login and registration page. You must run SSL-enabled Apache in order to use this feature. If you don't run SSL-enabled Apache, then the user authentication will be done via standard HTTP protocol, user credentials travelling in clear text across the net. The --with-sweburl option is optional. --with-dbhost=sqlserver.domain.com --with-dbname=cdsinvenio --with-dbuser=cdsinvenio --with-dbpass=myp1ss The database server host, the database name, and the database user credentials. --with-python=/opt/python/bin/python2.3 Optionally, specify a path to some specific Python binary. This is useful if you have more than one Python installation on your system. If you don't set this option, then the first Python that will be found in your PATH will be chosen for running CDS Invenio. CDS Invenio won't install to any other directory but to the one mentioned in this configuration line. Do not use trailing slashes when specifying any of the above values. This configuration step is mandatory, and is referred to as "pre-compile time configuration step a)" in the elucidative explanatory commentary below. Note that if you prefer to build CDS Invenio out of its source tree, you may run the above configure command like this: $ mkdir build && cd build && ../configure --prefix=... $ vi ./config/config.wml ## optional, but strongly recommended Optionally, customize your CDS Invenio installation. We strongly recommend you to edit at least the top of this file where you can define some very essential CDS Invenio parameters like the name of your CDS Invenio document server (look for CDSNAME and CDSNAMEINTL) or the email address of the local CDS Invenio administrator (look for SUPPORTEMAIL and ADMINEMAIL). The latter is needed if you want to use administration modules, and you will certainly do. The rest of the "config.wml" file enables you to change the CDS Invenio web page look and feel, and otherwise to influence its behaviour and default parameters. This configuration step is optional, but strongly recommended. It is referred to as "compile time configuration step b)" in the elucidative explanatory commentary below. $ make Launch the CDS Invenio build. Since many messages are printed during the build process, you may want to run it in a fast-scrolling terminal such as rxvt or in a detached screen session. During this step all the pages and scripts will be pre-created and customized based on the config you have edited in the previous step. Before proceeding further with the CDS Invenio installation, we have to do some admin-level tasks on the MySQL and Apache servers. $ mysql -h sqlserver.domain.com -u root -p mysql mysql> CREATE DATABASE cdsinvenio; mysql> GRANT ALL PRIVILEGES ON cdsinvenio.* TO cdsinvenio@webserver.domain.com IDENTIFIED BY 'myp1ss'; You need to create a dedicated database on your MySQL server that the CDS Invenio can use for its purposes. Please contact your MySQL administrator and ask him to execute the above commands that will create the "cdsinvenio" database, a user called "cdsinvenio" with password "myp1ss", and that will grant all rights on the "cdsinvenio" database to the "cdsinvenio" user. The credential values are the ones you have chosen in the configure line above. $ sudo vi /path/to/apache/conf/httpd.conf ## see below in part 2 Please ask your webserver administrator to put the following lines in your "httpd.conf" configuration file: AddDefaultCharset UTF-8 AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps This is to ensure that the browsers will get UTF-8 as the default page encoding, and that "*.php" files will be interpreted by the web server as PHP files. As mentioned above, the web pages will get installed into the `prefix/var/www' directory. Therefore you should specify something along the lines of: ServerSignature Off ServerTokens Prod NameVirtualHost * ServerName webserver.domain.com ServerAdmin cds.support@cern.ch DocumentRoot /opt/cds-invenio/var/www Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all ErrorLog /opt/cds-invenio/var/log/apache.err LogLevel warn CustomLog /opt/cds-invenio/var/log/apache.log combined DirectoryIndex index.en.html index.html index.py index.en.php index.php SetHandler python-program PythonHandler invenio.webinterface_layout PythonDebug On AddHandler python-program .py PythonHandler mod_python.publisher PythonDebug On This will tell Apache where to find the files, how to interpret .py files, which files to serve as indexes, etc. If you have configured the system to use secure URL for login (see above), then you have to specify secure site too, such as: ServerSignature Off ServerTokens Prod NameVirtualHost *:443 SSLCertificateFile /etc/apache2/ssl/apache.pem ServerName webserver.domain.com ServerAdmin cds.support@cern.ch SSLEngine on DocumentRoot /opt/cds-invenio/var/www Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all ErrorLog /opt/cds-invenio/var/log/apache-ssl.err LogLevel warn CustomLog /opt/cds-invenio/var/log/apache-ssl.log combined DirectoryIndex index.en.html index.html index.py index.en.php index.php SetHandler python-program PythonHandler invenio.webinterface_layout PythonDebug On AddHandler python-program .py PythonHandler mod_python.publisher PythonDebug On $ sudo vi /path/to/php/conf/php.ini ## see below in part 2 Please ask your webserver administrator to put the following lines in your "php.ini" configuration file: log_errors = on display_errors = off expose_php = off max_execution_time = 160 register_globals = on short_open_tag = on This will set up some relevant PHP variables. If your OS uses dynamic loading PHP MySQL libraries, such as Debian "Sarge" GNU/Linux, you will also have to specify: extension=mysql.so in both /etc/php4/{cli,apache2}/php.ini files. $ sudo /path/to/apache/bin/apachectl graceful Please ask your webserver administrator to restart the Apache server after the above "httpd.conf" and "php.ini" changes. After these admin-level tasks to be performed as root, let's now go back to finish the installation of the CDS Invenio package. $ make create-tables ## optional If you are installing for the first time, you have to create CDS Invenio tables in the database. Note that the `make install' process will warn you in case the tables were not created and will ask you to run this step manually before completing the make install process. $ sudo ln -s /opt/cds-invenio/lib/python/invenio \ /usr/local/lib/python2.3/site-packages/invenio \ ## optional If you are installing for the first time, you will have to create a symbolic link from Python's site-packages directory that would indicate to Python where to find CDS Invenio's Python files. Note that the exact symlink target location depends on the --prefix location (prefix/lib/python/invenio) and the exact symlink source location depends on the Python version you are using. (See also --with-python configuration option.) Note that the `make install' process will warn you in case the symbolic link was not created and it will indicate you the command to use to create it manually before completing the make install process. $ make install Install the web pages, scripts, utilities and everything needed for runtime into the respective directories, as specified earlier by the configure command. After this step, you should be able to point your browser to the chosen URL of your local CDS Invenio installation and see it running! $ make test Optionally, you can run our test suite to verify the results of known tests on your local CDS Invenio installation. Note that this command should be run only after you have installed the whole system via `make install'. $ sudo chown -R www-data /opt/cds-invenio/var One more superuser step, as we need to enable Apache server to write some log information and to cache interesting entities inside the "var" subdirectory of our CDS Invenio general installation directory. Here we assume that your Apache server processes are run under "www-data" group. Change this appropriately for your system. $ make create-demo-site ## optional This step is recommended to test your local CDS Invenio installation. It should give you our "Atlantis Institute of Science" demo installation, exactly as you see it at . $ make load-demo-records ## optional Optionally, load some demo records to be able to test indexing and searching of your local demo CDS Invenio installation. $ make remove-demo-records ## optional Optionally, remove the demo records loaded in the previous step but otherwise keep the demo collection, submit, format etc configurations that you may reuse and modify for production purposes. $ make drop-demo-site ## optional Optionally, drop also all the demo configuration so that you'll have a blank CDS Invenio system for your production purposes. $ firefox http://webserver.domain.com/admin/ ## optional Optionally, do further runtime configuration of the CDS Invenio, like definition of data collections, document types, document formats, word file tables, etc. This configuration step is optional, and is referred to as "runtime configuration step c)" in the elucidative explanatory commentary below. 3. Configuration philosophy explained and elucidated ==================================================== As you could see from the above, the configuration of the CDS Invenio is threefold: (a) pre-compile time configuration phase [uses command line options / while doing "configure"] (b) compile time configuration phase [uses WML / after "configure", while doing "make && make install"] (c) runtime configuration phase [uses MySQL / after "make install", while doing "netscape http://webserver.domain.com/DEMO/admin/"] What is the difference, and why? (a) pre-compile time configuration phase [uses command line options / while doing "configure"] This configures essential CDS Invenio parameters that makes your CDS Invenio copy installable and runable. The essential parameters include: general CDS Invenio installation directory containing (among others) binaries, libraries, and log and cache directories; install directory for Web scripts and pages; and MySQL user and server credentials. This configuration step uses standard GNU autoconf approach, i.e. you will run the standard "configure" script. Note that the only arguments that CDS Invenio takes into consideration are the general "--prefix" one and CDS Invenio-specific "--with-foo" arguments, see the end of "configure --help" output. This configuration step is mandatory. Without knowing theses essential parameters there is nothing to install and nothing to run. Usually, you do this step only once. (b) compile time configuration phase [uses WML / after "configure", while doing "make && make install"] Optionally, you may choose to influence CDS Invenio behaviour, to set up CDS Invenio system name, to choose its default parameters, to change its look and feel, to add your local web pages, etc. This configuration step uses WML, the Website META Language. The most important configuration file is "config/config.wml" that you can edit at your will. Optionally, if you are an advanced user, you may edit other WML files in the distribution tree. After that, when you type "make", the CDS Invenio pages will be pre-generated. We prefer that this configuration step is done during compile-time and not runtime, because of multiple reasons: (i) the pre-generated pages impose less load on the web server and the database server and so they are served faster to the end user; (ii) we use several different languages (Python, PHP) and by using independent compile-time configuration language we can share the same configuration variables across heterogeneous languages; (iii) use of WML and page templates enables you to easily change anything in the CDS Invenio system, even into deep levels. If you are changing parameters and/or look and feel of CDS Invenio pages, you may want to repeat these step several times: $ vi config/config.wml $ make drop-tables $ make create-tables $ make create-demo-site $ make load-demo-records $ firefox http://webserver.domain.com/ [...] to see what it brings, until you are satisfied with the result. (Note that you may as well choose to change these parameters inside the CDS Invenio library configuration files later on, during runtime, at least for non-static Python and PHP pages.) (c) runtime configuration phase [uses MySQL / after "make install", while doing "firefox http://webserver.domain.com/admin/"] Optionally, you will most probably want to define specific data collections, to configure submit and search page for those collections, to specify search options and word files to search in, formats how to display data, etc. This configuration step uses MySQL configuration tables and is done during the runtime, for your convenience. It means that after previous configuration step (b), and after successful "make install", if you are happy with its result you no longer edit WML files within the CDS Invenio source tree but rather configure "fully running" CDS Invenio installation via its Administration web interface. Usually, you will do this step many times in the future, to tweak the running installation, to add new collections and data types, etc. (Note that if you want to change something "deeper" in a running CDS Invenio installation, such as look and feel of pages, or to add some new pages, then you may want to edit library configuration files for Python and PHP non-static pages, as noted above. But if you want to do really "deep" changes, you need to go back to WML source, so you may want to leave your customized copy of the CDS Invenio WML source tree around.) We hope that this explains why we have chosen this three-level configuration model, and that you will find it convenient in real life. Good luck, and thanks for choosing CDS Invenio. - CDS Development Group
