• How To Install Zabbix Server 5.0 on CentOS 7

Platform to install

Prerequisites

php 7.2

Zabbix frontend requires PHP version 7.2 or newer starting with Zabbix 5.0. Note that RHEL/CentOS 7 only provide PHP 5.4. So don't install the php for pre-installed version on system.

Step 1: Install and Configure Apache httpd server

yum install httpd
systemctl start httpd
systemctl enable httpd

Step 2: Install MariaDB Database server

Remove MariaDB 5.x

systemctl stop mariadb
yum remove mariadb mariadb-server mariadb-libs

Add new MariaDB repository
https://downloads.mariadb.org/mariadb/repositories/#mirror=mephi&distro=CentOS&distro_release=centos7-amd64--centos7

vi /etc/yum.repos.d/mariadb.repo

# MariaDB 10.5 CentOS repository list - created 2020-08-17 13:04 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.5/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Install MariaDB

yum clean all
yum install MariaDB-server MariaDB-client

Config MariaDB

vi /etc/my.cnf.d/server.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log

新增目錄

mkdir /var/log/mariadb
chown mysql.mysql /var/log/mariadb

Start MariaDB

systemctl start mariadb
systemctl enable mariadb

Initial DB Configuration and set password for root

Step 3: Install and configure Zabbix server

a. Install Zabbix repository

# rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
# yum clean all

b. Install Zabbix server and agent

# yum install zabbix-server-mysql zabbix-agent zabbix-get

c. Install Zabbix frontend
Enable Red Hat Software Collections

# yum install centos-release-scl

Install Zabbix frontend packages.

This step will install the php 7.2 packages required for Zabbix.

# yum-config-manager --enable zabbix-frontend
# yum install zabbix-web-mysql-scl zabbix-apache-conf-scl

如果沒有安裝 yum-config-manager，可以改用以下指令安裝：

yum --enablerepo=zabbix-frontend

# mysql -uroot -p <<MYSQL_EOF
create database zabbix character set utf8 collate utf8_bin;
create user zabbix@localhost identified by 'thisispassword';
grant all privileges on zabbix.* to zabbix@localhost;
MYSQL_EOF

# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

DBName=zabbix
DBUser=zabbix
DBPassword=password

php_value[date.timezone] = Asia/Taipei

# systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
# systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

Optional: Other Zabbix components Installation

yum install zabbix-proxy-mysql

yum install zabbix-java-gateway
