##### 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
```

```
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

```
mysql_secure_installation
```

##### 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.

<p class="callout info">This step will install the php 7.2 packages required for Zabbix.</p>

```
# 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`
