yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent

3. 若沒有安裝 MySQL 或 Maria DB，請按照以下步驟安裝 Maria DB

1	vim /etc/yum.repos.d/MariaDB.repo

貼上以下內容（根據需求參考以下網址調整　http://downloads.mariadb.org/mariadb/repositories/ ）

# MariaDB 10.3 CentOS repository list - created 2019-05-28 01:56 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

1	yum install MariaDB-server MariaDB-client

4. 啟動 MariaDB 並設定開機啟動

1 2	systemctl start mariadb systemctl enable mariadb

5. 設定 MariaDB root 密碼

1	/usr/bin/mysqladmin -u root password 'new-password'

6. MariaDB 安全性設定

1	/usr/bin/mysql_secure_installation

7. 建立 Zabbix 用帳號 & Database

mysql -u root -p
Enter password:

MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

## 建立 zabbix 帳號，記得修改 <password> 並拿掉 <> ##
MariaDB [(none)]> CREATE USER 'zabbix'@'localhost' IDENTIFIED BY '<password>';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';  
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> quit
Bye

8. 將 Zabbix 初始 SQL 架構和數據導入 MariaDB

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

9. 編輯 zabbix_server.conf

vim /etc/zabbix/zabbix_server.conf

## 將 DB 密碼設成剛剛 zabbix@localhost 所設定的 ##
DBPassword=<password>

10. 編輯 zabbix.conf

vim /etc/httpd/conf.d/zabbix.conf

## 將 timezone 修改為 Asia/Taipei ##
php_value date.timezone Asia/Taipei
