ubuntu20.04下MySQL8的使用

1、安装

sudo apt-get install mysql-server

2、验证

systemctl status mysql

看到上面的信息就说明MySQL已经安装好并运行起来了。

3、配置

sudo mysql_secure_installation

4、登陆MySQL

sudo mysql -u root -p

5、远程连接配置

1、打开文件注释掉bind-address=127.0.0.1

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

2、重启MySQL服务

sudo /etc/init.d/mysql restart

3、连接MySQL

$ sudo mysql -u root -p

4、创建远程连接账户并授权

mysql> use mysql;

mysql> CREATE USER 'root'@'%' IDENTIFIED BY '123456';

mysql> grant all privileges on *.* to 'root'@'%';

密码简单了，请设置成复杂密码

5、远程连接时报错plugin caching_sha2_password could not be loaded 执行

 set global validate_password.policy=LOW;

 set global validate_password.length=6;

mysql> alter user 'root'@'%' identified with mysql_native_password by '123456';

6、刷新权限

mysql> FLUSH PRIVILEGES;

7、查看用户

mysql> select host, user, authentication_string, plugin from user;
