?CentOS?7?安装?mysql-server?爬坑
?发现问题
在centos?6安装?mysql-server是直接使用命令?yum?-y?install?mysql-server?，但是在CentOS?7中出现了?No?package?mysql-server?available.?Error:?Nothing?to?do?错误。详细错误信息如下：
[[email protected]?~]#?yum?-y?install?mysql-server

Error:?Nothing?to?do?解决方案
使用?MariaDB?代替?MySQL?命令即可
?产生原因
简单来说，MariaDB?是?MySQL?的fork，两者关系就好比?Red?Hat?和?CentOS?的关系。从?MySQL?变成了?Oracle?甲骨文公司的产品后，MySQL?就已经从?RHEL?和?CentOS?所提供的套件清单移除了。
?安装?MySQL
?1.?安裝?mariadb?与?mariadb-server?套件
sudo?yum?-y?install?mariadb?mariasb-client?2.?启动?MySQL?服务
sudo?systemctl?start?mariadb?3.?启动?MariaDB?服务，让?MariaDB?服务每次开机会自启
sudo?systemctl?enable?mariadb?4.?检查启动状态
sudo?systemctl?status?mariadb?5.?加强?MariaDB?安装的安全性
sudo?mysql_secure_installation这个shell主要是有以下作用：
-?设定?root?账号的密码
-?禁止?root?丛非本人登录
-?移除?anonymous?匿名用户登录
-?移除测试数据库
?6.?查询版本号
mysql?-v?登录测试
键入以下指令，输入密码即可。
