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
