After installing Plesk 8 on a RedHat 4 box I’ve needed to install Plesk 8 on Redhat 5.  RedHat 5 uses mod_jrun22.  Well it’s Apache 2.2 that uses mod_jrun22, so any version of Linux running Apache 2.2 will use this connector.

Since Plesk doesn’t support CF8 yet, it still writes out its apache directives looking for mod_jrun20.  This needs to be modified to get per domain support for CF8 and Apache 2.2

Warning this will void your warranty!

I grepped the plesk install directory looking for mentions of jrun.  I found a binary file that matched: /usr/local/psa/admin/sbin/websrvmng

Looking at this file, on line 228 there’s a mention of mod_jrun20 in plain text.  This is the part of the websrvmng that writes out the http directives.  After making a backup of this file I took a chance at making an edit.  I simply changed mod_jrun20 to mod_jrun22 and saved the file.

Sure enough, plesk is happy.  Now when checking the ColdFusion box in a domain setup I see <IfModule mod_jrun22.c> in the httpd.include file for that domain rather than <IfModule mod_jrun20.c>.

Be careful here, I’m sure this change would not survive a plesk update to websrvmng.  After each plesk update double check this file to make sure it still points to mod_jrun22.

When backing up mysql databases via mysqldump you can either specify a database name to backup or use the –all-databases switch to dump all databases in one big file. I’d like to backup all my databases but I’d like them in separate files so they’re easier to manage and I can do a quick restore of a single db if needed.

I wrote the following bash script to help out.


#!/bin/sh
for customerdb in `mysql -uroot -pROOTUSERPASS -e "show databases" -B -N`
do
mysqldump -uroot -pROOTUSERPASS $customerdb > /home/matt/backup/$customerdb.sql
done


Or on my plesk server, I’ve got a table in plesk’s psa database that lists out all the databases created within plesk. A modification to this script reads the table names in the psa database table and makes backups of all those.


#!/bin/sh
for customerdb in `mysql -uadmin -pADMINUSERPASS -e "select name from data_bases" -B -N psa`
do
mysqldump -uadmin -pADMINUSERPASS $customerdb > /home/matt/backup/$customerdb.sql
done
