Step 4 – Setup Zabbix Apache Configuration

Zabbix creates its own apache configuration file /etc/httpd/conf.d/zabbix.conf. Edit this file and just update timezone. More timezone’s

  php_value date.timezone Asia/Kolkata

After changing value restart Apache service.

service httpd restart

Step 5 – Configure MySQL Database for Zabbix

This installation is using MySQL as the backend of Zabbix, So we need to create MySQL database and User for Zabbix installation.

mysql -u root -p

mysql> CREATE DATABASE zabbixdb CHARACTER SET UTF8;
mysql> GRANT ALL PRIVILEGES on zabbixdb.* to [email protected] IDENTIFIED BY 'password';
mysql> FLUSH PRIVILEGES;
mysql> quit

After creating database restore the default mysql database provided by zabbix. These files can be found at /usr/share/doc/zabbix-server-mysql-<version>/create/ directory.

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uroot -p zabbixdb
zcat /usr/share/doc/zabbix-proxy-mysql*/schema.sql.gz | mysql -uroot -p zabbixdb

Now edit Zabbix server configuration file /etc/zabbix/zabbix_server.conf and update the following database configurations.

  DBHost=localhost
  DBName=zabbixdb
  DBUser=zabbix
  DBPassword=password
