Centos7安装Mysql
1、配置YUM源
下载mysql源安装包
shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
安装mysql源

检查mysql源是否安装成功
shell> yum repolist enabled | grep “mysql.-community.“
2、安装MySQL
shell> yum install mysql-community-server
3、启动MySQL服务
shell> systemctl start mysqld
4、开机启动
shell> systemctl enable mysqld
shell> systemctl daemon-reload
5、修改root默认密码
shell> grep ‘temporary password’ /var/log/mysqld.log
shell> mysql -uroot -p
mysql> ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘MyNewPass4!’;
或者
mysql> set password for ‘root’@’localhost’=password(‘MyNewPass4!’);
6.设置ip登录
检查root配置
root用户登录
$ mysql -u root -p
切换到mysql这个数据库
mysql> use mysql;
指定密码策略
validate_password_policy=0
set global validate_password_policy=0;
修改密码
update mysql.user set authentication_string=PASSWORD(‘ysrfeng-001’) where User=’root’;
给用户授权
mysql> grant all privileges on . to ‘root’@’%’ identified by ‘123456’ with grant option;
使配置生效
mysql> flush privileges;
