navicat遠程連接mysql出現1130的錯誤

用主機Natcivat連接服務器Mysql，出現錯誤提示：1130-Host‘XXX.XXX.XXX.XXX’ is not allowed to connect to this MySQL server

原因：遠程服務器無權限登錄MySQL

解決：

1.Ubuntu下登錄MySQL：mysql -uroot -p 

2.執行下命令

GRANT ALL PRIVILEGES ON *.* TO ‘你的用戶名’@’%’ IDENTIFIED BY ‘你的數據庫密碼’ WITH GRANT OPTION;

3.在執行下
flush privileges;

這個命令是刷新一下權限,不用重啓

以上只針對5.7以下版本。

5.7以上執行的時候會報錯誤

mysql> GRANT ALL PRIVILEGES ON *.* TO ‘XXX’@’%’ IDENTIFIED BY ‘ZZZZZ’ WITH GRANT OPTION;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> exit

mysql> GRANT ALL PRIVILEGES ON *.* TO 'XXX'@'%' IDENTIFIED BY 'ZZZZZ' WITH GRANT OPTION;  
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.  
mysql> exit  

這個時候，需要先執行刷新權限：

flush privileges;

flush privileges;
