配置mysql的远程登录

1. 启动mysql

sudo systemctl start mysqld
sudo systemctl status mysqld

2. 查看mysql初始化的密码

sudo cat /var/log/mysqld.log | grep password

3. 配置

mysql -uroot -p'password'
降低mysql密码的安全等级
set global validate_password_policy=0;
降低安全等级为0级的密码限制长度
set global validate_password_length=4;
set password=password("123456");
use mysql;
select user, host from user;
update user set host="%" where user="root";
flush privileges;
quit;
