使用wsl2 安装mysql，并通过windows连接

1、执行 sudo apt install mysql-server 安装mysql-server。本文mysql-server的版本是8.0

安装过程中会提示设置root密码，按照提示输入即可

2、验证安装 mysql -u root -p

3、修改root用户的远程访问权限 update user set host='%' where user='root';

4、刷新权限表FLUSH PRIVILEGES;

5、重启mysql 服务

mysql8.0如何重置root密码

1. 关闭mysql服务，使用skip-grant-tables 跳过权限验证

vi /etc/mysql/mysql.conf.d/mysqld.cnf

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
log-error       = /var/log/mysql/error.log

skip-grant-tables

2. 重启mysql服务 sudo service mysql start

3. 进入mysql，刷新权限表 flush privileges;

4. 查看root用户和密码字段先将密码滞空

   use mysql;

   查看用户列表select host, user, authentication_string, plugin from user;

   将旧密码制空 update user set authentication_string='' where user='root';

5. 删除skip-grant-tables限制，重启mysql服务，重连mysql，并重置密码

   use mysql;

   FLUSH PRIVILEGES;

   ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
