Dotster VPS Upgrade to PHP 5 and MySQL 5
May 7, 2007 | 9 Comments
I recently purchased a Dotster VPS and needed to get it upgraded to have PHP 5 and MySQL 5, rather than version 4 of both. These machines run CentOS, so the best plan was to use yum.
Unfortunately, yum is not installed initially, so the first step was to get and install all the prerequisites plus yum:
export MIRROR=http://mirror.centos.org/centos/4/os/i386/CentOS/RPMS/
wget ${MIRROR}python-sqlite-1.1.7-1.2.i386.rpm
wget ${MIRROR}sqlite-3.3.3-1.2.i386.rpm
wget ${MIRROR}python-urlgrabber-2.9.8-2.noarch.rpm
wget ${MIRROR}python-elementtree-1.2.6-4.2.1.i386.rpm
wget ${MIRROR}yum-2.4.3-1.c4.noarch.rpm
rpm -Uhv python-elementtree-1.2.6-4.2.1.i386.rpm
rpm -Uhv python-urlgrabber-2.9.8-2.noarch.rpm
rpm -Uhv sqlite-3.3.3-1.2.i386.rpm
rpm -Uhv python-sqlite-1.1.7-1.2.i386.rpm
rpm -Uvh yum-2.4.3-1.c4.noarch.rpm
Once that is in place, you need to enable CentOS Plus. Go into /etc/yum.repos.d/CentOS-Base.repo and under [centosplus] change “enabled=0″ to “enabled=1″.
Now you can simply execute ‘yum update’ and it should install both MySQL 5 and PHP 5 with all the necessary prerequisites (plus a number of other things…)
Update: A few other things to do:
- Remove /etc/php.d/ioncube-loader.ini This file will cause weirdness with PHP and throw “Failed loading /usr/lib/php4/php_ioncube_loader_lin_4.3.so: /usr/lib/php4/php_ioncube_loader_lin_4.3.so: undefined symbol: zend_hash_add_or_update” in /var/log/httpd/error_log
- Change php.ini memory_limit to be increased from the default of 8M, I recommend at least 32MB
- Tune your MaxClients setting in /etc/httpd/conf/httpd.conf I couldn’t begin to make a recommendation here…
Do this at your own risk, this could mess up your entire system. Be sure to have a good backup before starting this process.
