使用yum install mysql-community-server失败报错

这里需要修改mysql安装的配置源文件

解决方法：

修改vim /etc/yum.repos.d/mysql-community.repo 源文件

[mysql57-community]

name=MySQL 5.7 Community Server

## baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/   

baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql    

yum install mysql-community-server  #再次安装mysql

systemctl  start mysqld         #启动mysql
systemctl  status mysqld      #查看mysql启动状态
