Whenever you go to install applications and services on registered RHEL servers, it’s always nice to use the RPMs because up2date will keep everything current for you. Managing upgrades gets a whole lot easier when you can bring your system up to current with one simple command. Because of this, I decided that I would try to use as many RPMs as I could when I set up our latest Horde / IMP installation.
Unfortunately, RedHat does not supply RPMs for the Horde applications, but luckily CentOS does. You should be able to download them from here. Get the latest version, which at the time of this writing was horde-3.1.3-1 and imp-h3-4.1.3-1.
Don’t install them yet though because Horde and IMP have always had a lot of dependancies which must be installed and enabled first. Installing the following RPMs should take care of them.
Assuming you will want up2date to handle upgrades of these packages, it is very important that you either use “up2date” to install them, or download them from correct channel at the RedHat website. You could also simply get them from the CD distribution that you used to install the system itself.
Once PEAR is installed, you will have to upgrade it, and install the PEAR::Log module.
[root@server]# pear upgrade -a PEAR-1.3.6
[root@server]# pear upgrade PEAR
Ok, now let’s make sure the web server is configured to start when the system comes up:
[root@server /]# /sbin/chkconfig --list httpd
You should see this:
httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
But if you see 5:off, simply run:
[root@server /]# /sbin/chkconfig httpd on
Now we enable and start up our new MySQL database server:
[root@server /]# /sbin/chkconfig mysqld on
[root@server /]# /sbin/service mysqld start
And we’re ready to install Horde and IMP. Install the following RPM’s, which will put everything in /usr/share/horde and creates a file called horde.conf in /etc/httpd/conf.d/
This will install the HORDE and IMP packages in /usr/share, and /usr/share/horde respectively.
Finally, we start or restart apache:
[root@server /]# /sbin/service httpd start
Grab a browser and go to the following URL to proceed with the Horde and IMP configuration.
