在我們用客戶端及其遠(yuǎn)程連接服務(wù)器Mysql數(shù)據(jù)庫(kù)的過(guò)程中，容易出現(xiàn)下面問(wèn)題：
問(wèn)題代碼代碼
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.0.19' (111)
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.0.19' (111)這個(gè) 原因就是Mysql數(shù)據(jù)庫(kù)的默認(rèn)配置文件my.cnf（linux下）中的bind-address默認(rèn)為127.0.0.1，所以就算你創(chuàng)建了可以 remote訪問(wèn)的用戶，你也不能使用mysql -h命令進(jìn)行訪問(wèn)，若訪問(wèn)就會(huì)出現(xiàn)上出問(wèn)題，因?yàn)榇藭r(shí)Mysql只接受localhost，所以需要把bind-address屏蔽掉。

my.cnf一般在/etc/mysql下面，如果不在使用locate my.cnf查找，修改前的my.cnf配置文件為：

修改前的my.cnf配置文件代碼
#
# 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
#
# 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
我們需要做的就是屏蔽這個(gè)bind-address代碼，屏蔽后代碼為：

屏蔽后my.cnf配置文件代碼
#
# 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
#
# 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
現(xiàn)在你就可以用mysql -h命令進(jìn)行你想做的操作了，如登錄系統(tǒng)：

登陸數(shù)據(jù)庫(kù)代碼
