I want to upgrade my server to ubuntu 12.04, which has built in apache 2.4. Are there any guidelines with respect to ISPCONFIG which can be followed beforehand for a smooth update. Question like below need some clarification. 1. Do I need to manually update the existing Vhost files or it can be updated using ISPconfig. 2. Will ISPCONFIG panel will work if apache fails to start on upgrade. Thanks.
1) you can force a rewrite of all vhost files by using the ispconfig resync tool (see tools > resync in ispconfig). The apache version is detected in realtime, so if you have apache 2.4 installed at the time where the resync is run, then the vhost files will have apache 2.4 syntax. It might be a good idea to disable alls ites by deleting their symlinks in /etc/apache2/sites-enabled/ directory before you update and then let ispconfig update the vhosts, this will also recreate the missing symlinks. 2) No. ispconfig uses the same apache instance then the websites, so you cant access it until apache is stating again. Thats why I suggested above to disable all sites first.
