mysql5.6使用老格式密碼

文檔摘抄

root@mysql-5.1.51> SET SESSION old_passwords=0; Query OK, 0 rows affected (0.00 sec)

root@mysql-5.1.51> SELECT PASSWORD('123456'); +-------------------------------------------+ | PASSWORD('123456') | +-------------------------------------------+ | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | +-------------------------------------------+ 1 row in set (0.00 sec)

root@mysql-5.1.51> SET SESSION old_passwords=1; Query OK, 0 rows affected (0.00 sec)

root@mysql-5.1.51> SELECT PASSWORD('123456'); +--------------------+ | PASSWORD('123456') | +--------------------+ | 565491d704013245 | +--------------------+ 1 row in set (0.00 sec

實際操做： 登錄mysql，使用SET SESSION old_passwords=0; //設置老格式密碼 SET PASSWORD FOR 'webuser'@'localhost' = PASSWORD('123456') //而後爲用戶設置密碼。

修改配置文件： [client] secure_auth = 0 [mysqld] old_passwords=1

成功登錄！

忘記用戶密碼時： [mysqld] skip-grant-tables

而後不用口令進入mysql修改密碼：

UPDATE mysql.user SET Password=PASSWORD("newpassword") WHERE User='root' and Host='localhost';
