mysql5.6 root本地localhost登錄后無法授權
-
1，問題錯誤信息：
root@localhost:(none)>GRANT REPLICATION SLAVE ON . to 'yunwei'@'192.168.20.132' identified by '123456';
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) -
2，登錄mysql 查看root用戶權限
root@localhost:(none)> select * from mysql.user where User='root' and Host='localhost'\G;
*************************** 1. row ***************************
Host: localhost
User: root
Password: *262F7A2D18342B5E811B5772E55DED350BFD78B2

Reload_priv: Y
Shutdown_priv: Y
Process_priv: Y
File_priv: Y
Grant_priv: N
References_priv: Y

.......
.......可以看到Grant_priv是N。很顯然，因為root@localhost這個用戶沒有授予權限的權限，所以之前的操作報錯。 -
3，解決辦法：
執行語句： update mysql.user set Grant_priv='Y' where User='root' and Host='localhost';
刷新后重新登錄：
flush privileges;
切記要刷新權限再重新登錄。查看root權限，生效即可。

4，進行授權：
GRANT REPLICATION SLAVE ON . to 'yunwei'@'192.168.20.132' identified by '123456';
Query OK, 0 rows affected (0.11 sec)
root@localhost:(none)>flush privileges;
