# rpm -Uvh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm
[root@webhostingchennai ~]# rpm -Uvh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm

[root@webhostingchennai ~]#

Step 3:  Install Zabbix Server with MySQL.

Now use the following command to install Zabbix server with MySQL database support packages on your system.

# yum install zabbix-server-mysql zabbix-web-mysql zabbix-proxy-mysql

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 as follows.

php_value date.timezone Asia/Kolkata

Restart the service after modifying the configuration file.

# systemctl restart httpd.service

Step 5: Configuring 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
MariaDB [(none)]> CREATE DATABASE whczabbixdb CHARACTER SET UTF8;
MariaDB [(none)]> GRANT ALL PRIVILEGES on whczabbixdb.* to whczabbix@localhost IDENTIFIED BY 'password';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> quit

 

MariaDB [(none)]> CREATE DATABASE whczabbixdb CHARACTER SET UTF8;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> GRANT ALL PRIVILEGES on whczabbixdb.* to whczabbix@localhost IDENTIFIED BY 'password';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> quit

Bye

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 whczabbixdb

# zcat /usr/share/doc/zabbix-proxy-mysql*/schema.sql.gz | mysql -uroot -p whczabbixdb

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

DBHost=localhost
DBName=whczabbixdb
DBUser=whczabbix
DBPassword=password

Step 6: Start Zabbix Server.
