I have been trying to deploy SquirrelMail to my webserver, which is currently set up as Apache 2.0.40 and mod_jk2 to Tomcat 4.1.24 on JBoss3.2.1.

When I try and access any page in SquirelMail other than the log on page, I get a blank page come back, with no errors.

Looking in the Apache error_log (/var/log/httpd/error_log) shows a few PHP errors:

<code>PHP Fatal error:  Allowed memory size of 8388608 bytes exhausted (tried to allocate 4097 bytes) in
 /usr/share/squirrelmail/functions/imap_general.php on line 48</code>

This memory setting is in the /etc/php.ini file. Increasing this from 8M to 64M, and the max_execution_time from 30 to 120 fixed the memory and timeout problems.

The /var/log/messages file also showed the following error:

<code>Nov  7 11:17:52 localhost xinetd[20446]: libwrap refused connection to imap from 127.0.0.1
</code>

Adding imapd: 127.0.0.1 to /etc/hosts.allow fixed this.

02/21/06 This info is now long out of date. Google for mod_jk instead, which should be used instead of mod_jk2.

I’m setting up Apache on my Redat9.0 Linux server to run SquirrelMail, and amongt other things, re-enable/rebuild the Apache–>Mod-JK2–>JBoss3.x/Tomcat4.x confinguration I had running before my server’s harddrive failed 🙁

See the other post here in my JBoss section about downloading and installing the Mod-JK2 connector for connecting Apache to Tomcat.

It seems in order to install the Mod-JK2 connector on this version of RedHat9.0 I installed, I need to update my Apache server version as Mod-JK2 is dependent on a later version of httpd-mmn (whatever that is). I downloaded Httpd-2.0.51-2.7 from pbone.net, but this is dependent on a whole bunch of other stuff.

Not being too familiar with updating large numbers of dependent RPMs, I’ve found in the past that automated solutions such as Ximian’s RedCarpet are the easiest way (for me) to do this.

RedCarpet was dependent on later versions of glibc and glibc-common (2.3.2-27.9.7.i386), which I also donwloaded from pbone.net.

Next I installed the 3 RPM packages for RedCarpet.

Still in progress…

This is probably the easiest upgrade system I’ve found so far that also resolves dependencies:

Download YUM from http://linux.duke.edu/projects/yum/download.ptml

Run yum upgrade [packagename]

…and off it goes. I just usesd this to upgrade Httpd on my RedHat 9.0 and it updated a huge number of dependencies that would have taken me hours to do by hand…

Ximian’s RedCarpet is an automated package update system for Linux.
