查看Linux版本

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
因为Centos7 里面没有mysql的yum源，重新下载建立yum源，然后创建mysql数据库

[root@localhost ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

[root@localhost ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

[root@localhost ~]# yum install mysql-server
登录数据库

[root@localhost opt]# mysql -u root
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)

注意:/var/lib/mysql的访问权限问题，将该文件夹的所有者改为root用户

[root@localhost opt]# chown -R root:root /var/lib/mysql
重启mysqld 服务

[root@localhost opt]# service mysqld restart
重新登录mysql库

[root@localhost opt]# mysql -u root
