I’ve started to move myself over to Amazon EC2 servers. I still have some at Rackspace and like a lot of what they have to offer, but I think the seemingly lower cost and flexibility offered with EC2 is becoming better suited to my business. But that’s just me right now. The problem is, I am trying out their free tier usage right now, and have a micro server. That server has 600MB or RAM and by default comes with no swap. \u00a0A production server, in a perfect world, is never swapping, but a server with only 600MB of RAM could swap with one person looking at a drupal site. \u00a0It does slow the server down a lot, but’s acceptable for a dev server in my opinion and better than spending twice as much on a dev server that doesn’t swap. \u00a0After all, I usually develop locally so it’s more of a client review server than an actual dev server. \u00a0No one wants a server running out of RAM while a client is reviewing a site and mysql just randomly stopping on you.<\/p>\n
It only comes with an 8GB hard drive, which I alreadly have 1.3GB used with a single wordpress install, Ubuntu, Apache, PHP, and MariaDB, so using 1GB of that for swap might be risky, but I don’t imagine having much more than that on a dev server, so I’m gonna create a 1GB swap file on the hard drive.<\/p>\n
First I decided to create a swap directory in the root. Most people put swap on it’s own partitian at something like \/dev\/sda2, but I’m just gonna put mine at \/swp.<\/p>\n
[code]
\nsudo mkdir \/swp
\n[\/code]<\/p>\n
Then I create the swap file and set the right permissions.<\/p>\n
[code]
\nsudo fallocate -l 1024m \/swp\/1024MiB.swap
\nsudo chmod 600 \/swp\/1024MiB.swap
\n[\/code]<\/p>\n
Make it a swapping device.<\/p>\n
[code]
\nsudo mkswap \/swp\/1024MiB.swap
\n[\/code]<\/p>\n
Adding it to the system<\/p>\n
[code]
\nsudo swapon \/swp\/1024MiB.swap
\n[\/code]<\/p>\n
Add it to fstab to make it permanent<\/p>\n
[code]
\nsudo vim \/etc\/fstab
\n[\/code]<\/p>\n
Add this to the end of that file.<\/p>\n
[code]
\n\/swp\/1024MiB.swap none swap sw 0 0
\n[\/code]<\/p>\n
