Zabbix is an enterprise-class open source software for monitoring of networks and applications. It is designed to monitor and track the status of various network services, servers and applications. It offers advanced monitoring, alerting, and visualization features.
This is a step by step guide on "Installing Zabbix on CentOS" for MySQL monitoring. Monitoring mysql will be posted in seperate article.
Install Apache httpd
Order allow,deny
Allow from all
Order deny,allow
Deny from all
PHP Tuning
[root@localhost html]# vi /etc/php.ini
max_execution_time = 300
date.timezone =Asia/Calcutta
memory_limit = 256M
post_max_size = 32M
[root@localhost html]# /etc/init.d/httpd restart
Setup Web Frontend
Step:1
In browser, open Zabbix URL: http:///zabbix and follow the screen steps to complete the zabbix installation.
[root@localhost ~]# yum -y install httpd
Start httpd service
[root@localhost ~]# /etc/init.d/httpd start [ OK ]
[root@localhost ~]# ps -ef | grep http
root 2011 1 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2013 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2014 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2015 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2016 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2017 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2018 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2019 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
apache 2020 2011 0 11:46 ? 00:00:00 /usr/sbin/httpd
Location of httpd error & configuration file
[root@localhost ~]# cat /var/log/httpd/error_log
[root@localhost ~]# cat /etc/httpd/conf/httpd.conf
Now, apache should be working fine.
Install PHP and it's extension
[root@localhost ~]# yum -y install php
[root@localhost ~]# yum -y install php-mysql
PHP configuration file
[root@localhost ~]# cat /etc/php.ini
Install MySQL Server
[root@localhost ~]# yum -y install mysql-server mysql mysql-devel
[root@localhost ~]# /etc/init.d/mysqld start
MySQL configuration and error log file
[root@localhost ~]# cat /etc/my.cnf
[root@localhost ~]# cat /var/log/mysqld.log
Verification of apache, php and mysql
Create a 'phpinfo.php' file and copy and paste the following line into it:
