sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
3.安装mysql
sudo yum install mysql-server
根据提示安装就可以了,不过安装完成后没有密码,需要重置密码
4.重置mysql密码
mysql -u root
登录时有可能报这样的错:ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ : 使用下面的命令:
sudo chown -R root:root /var/lib/mysql
5、重启mysql服务
service mysqld restart
6、接下来登录重置密码
mysql -u root //直接回车进入mysql控制台 mysql > use mysql; mysql > update user set password=password('123456') where user='root'; mysql > exit;
