I want to be able to run multiple php versions on my development box running Ubuntu 12.04. What I want to accomplish is that when I use localhost as domain a default is used (let's say php 5.3.17). When I use 547.localhost as domain php 5.4.7 is used. I've seen some tutorials to get this working using fastcgi but until now I haven't been able to get it to work. I've looked at these tutorials: href="http://dbforch.wordpress.com/2010/05/21/apache2-fastcgi-multiple-php-versions-ubuntulucid-10-04/" rel="nofollow noreferrer">http://dbforch.wordpress.com/2010/05/21/apache2-fastcgi-multiple-php-versions-ubuntulucid-10-04/ href="http://www.metod.si/multiple-php-versions-with-apache-2-fastcgi-phpfarm-on-ubuntu/" rel="nofollow noreferrer">http://www.metod.si/multiple-php-versions-with-apache-2-fastcgi-php...

The problem is that php simply doesn't run. When I go to http://localhost/somephpfile.php it just outputs the source of the php file. The same for http://547.localhost/somephpfile.php . I'll break down what steps I took in the hope that someone is able to spot what I missed. First I installed a default lamp stack using sudo apt-get in...

Running cold fusion standard, so i can only have 1 instance of the coldfusion tomcat host per machine. https://helpx.adobe.com/coldfusion/configuring-administering/web-server-management.html#IIS says it's fine to have two websites send over to the same isntance, but i was wondering if it's still fine if the two websites are almost exactly the same code base, same file names, etc. We were looking at this option to run two slightly different sites of the same server, aka only change a few files and let vhost routing make it so different users get different experience. I understand double the load means double the resources for tomcat, but we you can assume it's properly sized. I'm just wondering if there are technical/concurrent problems with doing it this way. EG: would coldfusion compiler cache things incorrectly, or maybe it uses distinct class loaders per IIS virtualdir, or maybe it's all checksum based on the hash of the cfm file... Answer As l...

Why would someone want to outsource DNS? I heard about this in the stackoverflow podcast and got a bit curious to know why?

I'm new to managing servers, and I've run into something that's stumped me. I received a warning from my VPS provider informing me that my load usage was very high. I hadn't run into this problem before, so I attempted to look into it. Unfortunately I haven't been able to figure out why this is the case after quite a bit of research. The server is, I believe, OpenVZ, with plenty of RAM to spare (2 GB) and a decent processor with a SSD. I've shut down nearly every process that I could imagine that might be an issue besides apache. I've inspected my top/htop output very carefully and I can't detect anything unusual. But notice the load average. It should be around 0 with this level of CPU usage, right? href="https://i.stack.imgur.com/1cOEs.png" rel="nofollow noreferrer"> src="https://i.stack.imgur.c...

I was wondering if it was maybe something to do with disk usage, but since this is OpenVZ apparently I can't use a tool like atop to determine more information about disk activity. How can I debug this further? Thanks!
