远程连接mysql
解决方法(转):---但执行第一种办法时出现错误,第二种办法成功
1。改表法。可能是你的帐号不允许从远程登陆,只能在localhost。这个时候只要在localhost的那台电脑,登入mysql后,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,从"localhost"改称"%"
mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user;
2. 授权法。例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器,并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
这上面的方法主要就是在名为“mysq”的l数据库中把user表的host字段增加一个“%”,如果还是不能远程连接,那么应该是防火墙阻止了远程访问mysql占用的端口,放行即可。

所以除了给账户权限以外 还有修改 /etc/mysql/my.cnf
找到 bind-address = 127.0.0.1 修改为 bind-address = 0.0.0.0
重启mysql : sudo /etc/init.d/mysql restart
否则会报 ERROR 2003 (HY000): Can't connect to MySQL server on 'x.x.x.x' (111)
好吧 我是mysql菜鸟 以前都是走localhost的
