mysql主流版本5.5/5.6/5.7/8.0重置修改密码方法

最近几天来回切换各个Mysql版本重置密码，记录一下各个版本重置密码的方法。

MySql 5.5

SET PASSWORD FOR 'username'@'localhost' = PASSWORD('new_password');

MySql5.6

SET PASSWORD FOR 'username'@'localhost' = 'new_password';

MySql5.7

ALTER USER 'username'@'localhost' IDENTIFIED BY 'new_password';

或

ALTER USER 'username'@'localhost' IDENTIFIED WITH 'mysql_native_password' BY 'new_password';

MySql8.0

ALTER USER 'username'@'localhost' IDENTIFIED WITH 'mysql_native_password' BY 'new_password';

注意

• username是数据库账号
• localhost 是指账号对应的host主机字段值，需要按实际情况填写
• new_password 新密码
• mysql_native_password mysql 在8.0+中可以设置密码的插件可以选择的更安全的插件还有caching_sha2_password
