Posted 2020-11-19 KevinEngineer

安装mysql

1.sudo apt-get install mysql-client mysql-server

启动

2.service mysqld start

登陆

3.mysql -uroot

报错Access denied for user ‘root‘@‘localhost‘

先关闭mysql

4.service mysqld stop

安全启动MySQL（跳过密码验证）

5./usr/bin/mysqld_safe --skip-grant-tables

又报错mysqld_safe Directory ‘/var/run/mysqld‘ for UNIX socket file don‘t exists

解决方法

6.mkdir -p /var/run/mysqld

7.chown mysql:mysql /var/run/mysqld

重新安全启动

8./usr/bin/mysqld_safe --skip-grant-tables

打开另一个终端，登陆mysql

9.mysql -uroot

修改密码

10.grant all privileges on *.* to ‘root‘@‘localhost‘ identified by ‘123465‘ with grant option;

报错ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

修改读写权限

11.set global read_only=0;

flush privileges;

再次修改密码，报错Plugin ‘auth_socket‘ is not loaded

修改user表

12.update user set plugin="mysql_native_password";

flush privileges;

再次修改密码

13.grant all privileges on *.* to ‘root‘@‘localhost‘ identified by ‘123465‘ with grant option;

flush privileges;

 

修改成功
