虚拟机linux端mysql数据库无法远程访问的解决办法_MySQL

May 30, 2016 pm 05:10 PM

对于解决虚拟机linux端mysql数据库无法远程访问的办法一种,以下内容我给大家整理了两种解决方案,具体内容如下:

解决方法一:

1、 在控制台执行 mysql -u root -p mysql,CentOS系统提示输入数据库root用户的密码,输入完成后即进入mysql控制台

2、 在mysql控制台执行 GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'MyPassword' WITH GRANT OPTION; FLUSH PRIVILEGES;

3、 在mysql控制台执行命令中的 'root'@'%' 可以这样理解: root是用户名,%是主机名或IP地址,这里的%代表任意主机或IP地址,你也可替换成任意其它用户名或指定唯一的IP地址;'MyPassword'是给授权用户指定的登录数据库的密码;另外需要说明一点的是我这里的都是授权所有权限,可以指定部分权

4、 切换到root用户 打开iptables的配置文件:vi /etc/sysconfig/iptables

添加红色字体

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
Copy after login

全部修改完之后重启 iptables:service iptables restart

可以验证一下是否规则都已经生效:iptables -L 这样

我们就完成了CentOS防火墙的设置修改。

在远程:mysql -h 192.168.16.128 -u root2 -p 输入密码 root2 成功~

解决方法二:

具体内容请看下面代码:

mysql -uroot -p
Enter password: 
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'sy31214' WITH GRANT OPTION;
mysql>FLUSH PRIVILEGES;
Copy after login

以上所述就是本文的全部内容,对于虚拟机linux端mysql数据库无法远程访问的解决办法还有好多种,欢迎各位大侠多多分享自己的解决方案,本文写的不好,望多多提出批评建议。
