Zabbix自动化监控QQ交流群:9888359 欢迎喜欢交流的朋友加入！一、系统环境
cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
关闭防火墙及selinux
systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
grep SELINUX=disabled /etc/selinux/config
setenforce 0
二、数据库安装及配置
1、MariaDB概述
MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可。
开发这个分支的原因是：甲骨文公司收购了MySQL后，有将MySQL闭源的潜在风险，因此社区采用分支的方式来避开这个风险。
MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。
2、安装mariadb
yum install mariadb-server mariadb -y
mariadb数据库的相关命令是：
systemctl start mariadb #启动MariaDB
systemctl stop mariadb #停止MariaDB
systemctl restart mariadb #重启MariaDB
systemctl enable mariadb #设置开机启动
