Wiki online!
Figured it out...elementary mistake. There was still one of the DC's in resolv.conf. Finally discovered this when I saw that the httpd access_log was not updating even though I'd just refreshed the wiki page. Well, discovered in the sense that it ruled out httpd/php errors/issues, and I had already ruled out the mysql back-end. So figured had to be network-related somehow. Thankfully re-pointing everything was a simple affair with Astaro - just re-number the Nagios server object's IP. Anyways...now just have to get a solid backup routine going for all the pertinent areas: Wiki: - /srv/mediawiki/* - /etc/php.ini - /etc/httpd/* mysql: - DB backups - /etc/my.cnf nagios: - The entire VM, really.
