1, monitoring script download and configuration

wget http://mysql-cacti-templates.googlecode.com/files/better-cacti-templates-1.1.8.tar.gz
Tar zxvf better-cacti-templates-1.1.8.tar.gz
CD better-cacti-templates-1.1.8
CP scripts/ss_get_mysql_stats.php/var/www/html/cacti/scripts/

Only two files are needed to monitor MySQL:

Template file:./templates/cacti_host_template_x_mysql_server_ht_0.8.6i-sver1.1.8.xml
Plugins:./scriptsss_get_mysql_stats.php
To modify the ss_get_mysql_stats.php file:

vim/var/www/html/cacti/scripts/ss_get_mysql_stats.php

The MySQL server is configured so that the cacti machine can access the state information of the MySQL server and must have "process" permission. If you want to monitor the InnoDB state, you must also have "SUPER" permission.

Mysql> Grant Process,super on *.* to ' cactiuser ' @ '% ' identified by ' cactiuser '; Mysql> grant all privileges on cacti.* to  cactiuser@ "%" identified by "Cactiuser" mysql> flush;
