--当修改密码时提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
需要修改validate_password_policy的值：
mysql> set global validate_password_policy=0;
再查看
mysql> select @@validate_password_length;
--当卸载mysql提示error reading information on service mysqld: Invalid argument
可使用命令：rpm -e --nopreun --nopostun --nodeps
mac mysql error You must reset your password using ALTER USER statement before executing this statement.
安装完mysql 之后，登陆以后，不管运行任何命令，总是提示这个
step 1: SET PASSWORD = PASSWORD(‘your new password‘);
step 2: ALTER USER ‘root‘@‘localhost‘ PASSWORD EXPIRE NEVER;
step 3: flush privileges;
MySQL修改用户密码 ！
