虚拟机中MySQL连接问题：Lost connection to MySQL server at 'reading initial communication packet, system e

Posted 2020-08-23 dreamingodd

环境：在VirtualBox中安装了Ubuntu虚拟机，网络使用了NAT模式，开启了端口转发。

局域网内其他计算机访问虚拟机中的mysql Server出现两个问题：

Lost connection to MySQL server at \'reading initial communication packet, system error: 0

以及

host is not allowed to connect mysql

 

1.解决Lost connection to MySQL server at \'reading initial communication packet, system error: 0

修改/etc/mysql/my.cnf

注释#bind-address = 127.0.0.1

在[mysqld]中加入skip-name-resolve

 

2.解决host is not allowed to connect mysql

进入mysql库：

grant all privileges on *.* to \'root\'@\'%\' identified by \'YourPassword\' with grant option;
