Installing EPrints 3 on Redhat Enterpise 4
This guide has been written by combining the instructions for Eprints version 2, other contributions written by previous authors (Thanks guys!) and my experience with installing on my system. Please feel free to add, edit and put right anything I have got wrong!
It's a work in progress, which will be constantly updated, I will rewrite and move some of this once I have RC1 live next week.
Install Prerequisites
OS Updates
Install Red Hat Enterprise Linux 4 and the latest Updates available through Red Hat Network. If RHN is working, use it to get all the required packages:
up2date --nox -u httpd wget gzip xpdf lynx unzip up2date --nox -u mod_perl perl-DBI perl-DBD-MySQL perl-XML-Parser
Note: you will need to make sure your machine has the "Extras" channel in RHN or install mysql-server from the 'extras' disk, even if you selected to install MySQL in the menus:
up2date --nox -u mysql-server
If you want the LaTeX functionality install a TeX system and ImageMagick:
up2date --nox -u tetex-latex ImageMagick
You will needthe glib-devel and libxml2-devel package for GDOME
up2date --nox -u glib-devel libxml2-devel-2.6.16-6
Mod_Perl
I have found that the RHEL mod_perl version 2 is of course not version 2, but beta 1.99. RH offer mod_perl 2, but only in the Web Application Channel. This should be OK, on RHN alter your channel subscription and include :
Red Hat Web Application Stack 1.0 Beta (for AS v. 4 x86)
Then from the command line :
up2date --nox -u mod_perl
This will install mod perl 2.02 (latest) and un update to Perl.
Once loaded please alter the channel subscription back to your normal list.
Other Perl Modules
You can use CPAN with the automated script which comes with eprints; run "cpan" and answer the questions.
cpan perl -MCPAN -e shell install Data::ShowTable install MIME::Base64 install Unicode::String install Term::ReadKey install Readonly ******NEW******* install MIME::Lite install XML::LibXML install CGI (This is an update as I found RHEL dist has a bug for something else)
Accept and requirements, but don't worry about any modules already installed, then exit cpan (type exit) and run the perlmodule installer which came with EPrints.
Make sure apache & mysql start when you reboot
/sbin/chkconfig mysqld on /sbin/chkconfig httpd on
Installing GDOME and the perl GDOME interface
I found I needed this for eprints to work, so maybe it is essential now!
This is not essential. Non-RH RPMs are available at http://linux.reb00t.com/RPMS/
libxml2 should already be installed.
Install the GDOME rpms.
cd /root wget http://gdome2.cs.unibo.it/rpm/gdome2-0.8.1-1.i386.rpm wget http://gdome2.cs.unibo.it/rpm/gdome2-devel-0.8.1-1.i386.rpm rpm -Uvh gdome2-0.8.1-1.i386.rpm gdome2-devel-0.8.1-1.i386.rpm
(You can get more recent versions if they are available).
Fix the bug in gdome-config
When I installed gdome-config it appeared to have a slight error when it installed.
To see if the bug is a problem run:
gdome-config --libs
If you get something like:
/usr/bin/gdome-config: line 86: --libs: command not found /usr/bin/gdome-config: line 87: --cflags: command not found
then you need to fix the bug. Don't worry, it's easy.
As root edit /usr/bin/gdome-config
vi /usr/bin/gdome-config
Around line 88 find these two lines:
the_libs="$the_libs -L${exec_prefix}/lib -lgdome ` --libs` `xml2-config --libs`"
the_flags="$the_flags -I${prefix}/include -I${prefix}/include/libgdome ` --cflags` `xml2-config --cflags`"
And change them to this:
the_libs="$the_libs -L${exec_prefix}/lib -lgdome `/usr/bin/glib-config --libs` `xml2-config --libs`"
the_flags="$the_flags -I${prefix}/include -I${prefix}/include/libgdome `/usr/bin/glib-config --cflags` `xml2-config --cflags`"
Install XML::GDOME
note: you need the RPM glib-devel installed for this to work. (Possibly "up2date glib-devel" will sort this if up2date is set up)
Do this from source, not via CPAN as one of the tests is broken.
cd /usr/local/build wget http://cpan.uwinnipeg.ca/cpan/authors/id/T/TJ/TJMATHER/XML-GDOME-0.86.tar.gz tar xzvf XML-GDOME-0.86.tar.gz cd XML-GDOME-0.86 perl Makefile.PL make make install
If you want you can run "make test" before install, but don't worry about the "SAX" test failing.
Installing Eprints Version 3
Download Latest Version :
cd /usr/local/build wget http://files.eprints.org/130/01/eprints-3.0-rc-1.tar.gz
Unpack the distribution and compile (note I am running as apache user not eprints):
tar xzvf eprints-3.0-rc-1.tar.gz cd eprints-3.0-rc-1 ./configure --with-smtp-server=smtp.adastral.ucl.ac.uk --prefix=/var/lib/eprints3 --with-user=apache --with-group=apache ./install.pl
Obviously you should use setting relevant to your site, a complete list of options can be generated using the command:
./configure --help
Configure Apache
Edit the apache config:
vi /etc/httpd/conf/httpd.conf
add this to the end:
Include /var/lib/eprints3/cfg/apache.conf
Configure SELinux
If you haven't disabled SELinux, configure it as documented on the troubleshooting page, or apache will not be able to write data files.
Set up the indexer as a linux service
To make the indexer into a service which starts and stops on reboots etc. like httpd and mysqld do the following (as root):
ln -s /var/lib/eprints3/bin/epindexer /etc/init.d/epindexer chkconfig --add epindexer chkconfig epindexer on
The epindexer script runs as root, changes user to "apache" (or whatever uid your eprints install runs as) and then calls indexer.
