CentOS下yum安装mysql

Posted 2021-04-06 失忘LHY

1.下载mysql的repo源

$ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

2.安装mysql-community-release-el7-5.noarch.rpm包

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

3.安装mysql

$ sudo yum install mysql-server

4.重置mysql密码

$ mysql -u root
mysql > use mysql;
mysql > update user set password=password('123456') where user='root';
mysql > exit;

重启服务生效。

如果报错ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)，需要将mysql的拥有着改为当前用户并重启mysql服务：

$ sudo chown -R root:root /var/lib/mysql

$ service mysqld restart
