mysql允许远程连接
1. 3306端口是不是没有打开?
使用nestat命令查看3306端口状态:
~# netstat -an | grep 3306
tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN
从结果可以看出3306端口只是在IP 127.0.0.1上监听,所以拒绝了其他IP的访问。
解决方法:修改/etc/mysql/my.cnf文件。打开文件,找到下面内容:
# 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
把上面这一行注释掉或者把127.0.0.1换成合适的IP,建议注释掉。
重新启动后,重新使用netstat检测:
~# netstat -an | grep 3306tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
2. 问题解决了吗?
现在使用下面命令测试:
~# mysql -h 10.1.1.2 -u root -p
Enter password:
ERROR 1130 (00000): Host 'B0324-Desktop.local' is not allowed to connect to this MySQL server
结果出乎意料,还是不行。
解决方法:原来还需要把用户权限分配各远程用户。
登录到mysql服务器,使用grant命令分配权限
mysql> grant all on database_name.* touser_name@'%' identified by 'user_password';
其中database_name、user_name和user_password根据实际情况设置。
完成后使用mysql命令连接,提示成功,为了确保正确可以再远程登陆测试一下
