My checklist for Linux setup

2008-11-03 15:30:37

Every few years or so I need to migrate this site (and others) to a new hosted server. Here is my checklist for what packages to install, and other stuff to do. At the moment, I'm using CentOS 5. So far, I haven't decided to go the virtualization route; even though virtual hosted servers are cheaper, they don't have the horsepower to run some of the bigger sites I host. (hint: not this blog.)

Packages (via yum):

emacs postfix mysql-devel freetype-devel (for RRDtool) libpng-devel libart_lgpl-devel

Directories to tar/rsync over:

web document roots /home dirs /usr/local

Critical configs:

/etc/httpd/conf and conf.d /etc/sysconfig/iptables /etc/passwd /etc/shadow /etc/group /etc/sudoers /etc/ssh/sshd_config

Misc tasks:

Cutover procedure

  1. put up global "we are moving" web page on all sites

  2. dump/restore mysql data to new server

  3. bring up httpd with /etc/hosts file on my machine pointing to new server

  4. test

  5. change DNS to point to new server
