[root@zabbixserver ~]# sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
[root@zabbixserver ~]# reboot

Install apache and mariadb

[root@zabbixserver ~]# yum update
[root@zabbixserver ~]# yum install httpd mariadb-server -y

Start Apache and mariaDB Services.

[root@zabbixserver ~]# systemctl enable httpd && systemctl start httpd

Please refer mysql_secure_installation.

Install Zabbix Server with MySQL

Before starting the installation we need to enable the zabbix repository using this commands:

[root@zabbixserver ~]# rpm --import http://repo.zabbix.com/RPM-GPG-KEY-ZABBIX
[root@zabbixserver ~]# rpm -ivh https://repo.zabbix.com/zabbix/4.3/rhel/7/x86_64/zabbix-release-4.3-3.el7.noarch.rpm

Retrieving https://repo.zabbix.com/zabbix/4.3/rhel/7/x86_64/zabbix-release-4.3-3.el7.noarch.rpm

[root@zabbixserver ~]#

Now use the below command to install Zabbix and necessary packages

[root@zabbixserver ~]# yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-get zabbix-sender zabbix-java-gateway -y

Edit PHP timezone

Open the file /etc/httpd/conf.d/zabbix.conf created by Zabbix with your favorite editor.

[root@zabbix ~]# vi /etc/httpd/conf.d/zabbix.conf

It’s necessary to uncomment the “date.timezone” setting and replace it with your timezone:

php_value date.timezone Asia/Kolkata

Save the file and don’t forget to restart httpd service using the below command:

[root@zabbix ~]# systemctl restart httpd

Edit create and import initial zabbix database and user

First we need to create zabbix database (zabbixdb) and create a zabbix user (zabbixuser).

[root@zabbixserver ~]# mysql -u root -p
Enter password:Welcome to the MariaDB monitor. Commands end with ; or \g.Your MariaDB connection id is 10Server version: 5.5.60-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE DATABASE zabbixdb CHARACTER SET utf8 COLLATE utf8_bin;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON zabbixdb.* TO zabbixuser@localhost IDENTIFIED BY "Your Password";
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> exit
Bye
[root@zabbixserver ~]#

After creating the Zabbix database and user we need to import the zabbix initial database using the below commands:

[root@zabbixserver ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -u zabbixuser -p zabbixdb

Now we need to edit database configuration in the Zabbix server configuration file zabbix_server.conf

[root@zabbix ~]# vi /etc/zabbix/zabbix_server.conf
Specify the database name for zabbix , database user name and the password
DBHost=localhost
DBName=zabbixdb
DBUser=zabbixuser
DBPassword=YOUR_PASSWORD

Now enable and start zabbix service

[root@zabbixserver ~]# systemctl enable zabbix-server
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-server.service to /usr/lib/systemd/system/zabbix-server.service.
[root@zabbixserver ~]# systemctl start zabbix-server
[root@zabbixserver ~]# systemctl enable zabbix-agent
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
[root@zabbixserver ~]# systemctl start zabbix-agent
[root@zabbixserver ~]#
