mysql授權GRANT ALL PRIVILEGES 1。 改表法。 可能是你的帳號不允許從遠程登陸,只能在localhost。這個時候只要在localhost的那台電腦,登入mysql後,更改 "mysql" 數據庫裡的 "user" 表裡的 "host" 項,從"localhost"改稱"%" www.2cto.com Sql代碼 1. mysql -u root -pvmwaremysql>use mysql; 2. mysql>update user set host = '%' where user = 'root'; 3. mysql>select host, user from user; 2. 授權法。 例如,你想myuser使用mypassword從任何主機連接到mysql服務器的話。 Sql代碼 1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; 2.FLUSH PRIVILEGES; 如果你想允許用戶myuser從ip為192.168.1.6的主機連接到mysql服務器,並使用mypassword作為密碼 Sql代碼 1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 2. 'mypassword' WITH GRANT OPTION; 3. FLUSH PRIVILEGES; GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; FLUSH PRIVILEGES; 如果你想允許用戶myuser從ip為192.168.1.6的主機連接到mysql服務器的dk數據庫,並使用mypassword作為密碼 Sql代碼 1. GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 2. 'mypassword' WITH GRANT OPTION; 3. FLUSH PRIVILEGES; GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; FLUSH PRIVILEGES; 注意授權後必須FLUSH PRIVILEGES;否則無法立即生效。 另外一種方法. 在安裝mysql的機器上運行: 1、d:\mysql\bin\>mysql -h localhost -u root //這樣應該可以進入MySQL服務器 2、mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION //賦予任何主機訪問數據的權限 3、mysql>FLUSH PRIVILEGES //修改生效 4、mysql>EXIT //退出MySQL服務器 這樣就可以在其它任何的主機上以root身份登錄啦! 其它: mysql> grant all privileges on *.* to 'energy_pf'@'192.168.2.65' identified by 'energy_pf' with grant option; Query OK, 0 rows affected (0.00 sec) mysql> plush privileges; 允許用戶energy_pf從ip為192.168.2.65的主機連接到mysql服務器的任意數據庫(*.*),並使用energy_pf作為密碼
