mysql error number 2003
Can't connect to MySQL server xxx.xxx.xxx.xxx (10061)
在ubuntu 9.04中默認安裝了mysql,默認只能本地訪問,google了一下:
采用
登錄到MySQL服務器端,在mysql庫下執行
grant all on *.* to 'remote'@'172.16.21.39' identified by 'password';
即可
如果要設置為任何客戶端都可以以root連接的話,可以這么寫:
grant all on *.* to 'root'@'%' identifiied by 'root的密碼'
格式:grant select on 數據庫.* to 用戶名@登錄主機 identified by "密碼"
類似這用方法的整理如下:
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的那臺電腦,登入mysql后,更改 "mysql" 數據庫里的 "user" 表里的 "host" 項,從"localhost"改稱"%"
mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';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。
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; |
如果你想允許用戶myuser從ip為192.168.1.3的主機連接到mysql服務器,并使用mypassword作為密碼
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; |
但問題仍沒有解決:
找到 命令 mysql> flush privileges //使修改生效
顯示影響了零行。
問題依然沒有解決,重新啟動mysql sudo /etc/init.d/mysql restart
還是不行。

了解到mysql有本機綁定,找到問題所在。
編輯 /etc/mysql/my.cnf
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1
將”bind-address = 127.0.0.1“注釋
sudo /etc/init.d/mysql restart重啟即可遠程訪問
問題解決
