ubuntu mysql遠程連接

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的那台電腦，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，並使用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。

從 http://www.blogjava.net/waterjava/archive/2008/04/27/196385.html

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

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'

進入mysql,
grant all on *.* to 'root'@'%' identifiied by 'root的密碼'
