GNet Solutions » GNU/Linux Administration

I encountered a problem where one of my hosted web sites would periodically fail to load and display errors. I managed to track the problem down, when I make changes to web sites in ISPConfig it makes changes to the primary web node, but not to the other worker nodes that are set as mirrors of the primary web node. To work around this until a more appropriate solution can be created, I have made a script to synchronize the available websites on the primary node.

#!/bin/bash
# Script to synchronize the primary web nodes available web sites to  listed servers, then restart the web server

hosts="web-node2 web-node3 web-node4";

# Run rsync of available each website on web server node, then restart web server
for i in $hosts;
do
  echo $i;
  rsync -avh /etc/apache2/sites-available/ -e ssh $i:/etc/apache2/sites-available/
  ssh $i service apache2 restart
done;

I ran the script on the primary web nodes, and the problem was solved.

Note: As the web services grow, I may need to mount this as an NFS share.
