  • 【记】本地远程连接VM VirtualBox中虚拟机Centos6的数据库MySQL

    目标:远程连接虚拟机中的MySQL

    效果图如下

    1. VBox设置好端口转发

    具体步骤请看 VM VirtualBox 网络地址转换(NAT)使用详解

    2. MySQL授权

    如果这时我们就去远程连接MySQL数据库,会提示

    必须先授权,授权方法有多种,这里只介绍其中的一种

    mysql> grant all privileges on *.* to 'root'@'%' identified by 'root' with grant option;
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> flush privileges;
    Query OK, 0 rows affected (0.01 sec)

    这时远程登录,仍然失败

    C:UsersAdministrator>mysql -h 192.168.56.1 -P 33060 -u root -p
    Enter password: ****
    ERROR 2013 (HY000): Lost connection to MySQL server at 'waiting for initial communication packet', s
    ystem error: 0

    3. 关闭防火墙 

    本地环境要关闭防火墙

    虚拟机也要关闭防火墙

    Linux关于启动和关闭防火墙的命令:

    1) 重启后生效
      开启: chkconfig iptables on
      关闭: chkconfig iptables off
    2) 即时生效,重启后失效
      开启: service iptables start
    关闭: service iptables stop

    关闭防火墙之后,远程登录就成功了

    C:UsersAdministrator>mysql -h 192.168.56.1 -P 33060 -u root -p
    Enter password: ****
    Welcome to the MySQL monitor.  Commands end with ; or g.
