First we need to install some Mysql-Munin perl libraries:
apt-get install libipc-sharelite-perl
Also some Perl stuff will be needed:
perl -MCPAN -eshell
install IPC::ShareLite
Next let’s activate Munin Mysql plugin:
Assuming you have already installed both munin & mysql
ln -s /usr/share/munin/plugins/mysql_* /etc/munin/plugins
Restart both Apache & Munin:
/etc/init.d/apache2 restart
/etc/init.d/munin-node restart
su munin -c /usr/bin/munin-cron
