centos7.4安装mysql

yum -y install mysql mysql-server mysql-devel

mysql-server报错：No package mysql-server available，另外两个没问题

直接从官网安装mysql-server

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

rpm -ivh mysql-community-release-el7-5.noarch.rpm

yum install mysql-community-server

 

执行 service mysqld start

显示Redirecting to /bin/systemctl start  mysqld.service 表示成功开启mysql服务

或者执行 systemctl start mysqld.service

 

执行mysql进入界面
