远程连接centos7虚拟机（virtualbox）

Question

在virtualbox上安装了centos7系统。主机是 linux mint。我也安装了 centos7 httpd、mariadb、php 和 phpadmin 7。在centos7虚拟机上可以。 我想从主机（linux mint）连接到 phpadmin 和 mariadb，我有 IDE 来开发我的应用程序。

这是centos7的ip地址（ip地址命令）：

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host valid_lft forever preferred_lft forever

2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 08:00:27:0e:9b:d8 brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.15/24 brd 10.0.2.255 scope global dynamic enp0s3
       valid_lft 85621sec preferred_lft 85621sec
    inet6 fe80::db89:b43e:da69:530d/64 scope link
       valid_lft forever preferred_lft forever

3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN qlen 1000
    link/ether 52:54:00:8d:17:89 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever
4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN qlen 1000
    link/ether 52:54:00:8d:17:89 brd ff:ff:ff:ff:ff:ff

这是centos7上的phpmyadmin.conf：

我尝试从主机 linux mint 连接，但连接不正常。 我认为宿主机在虚拟机上看不到centos7....

你知道吗？

谢谢...

Answer 1

您是否为该应用程序启用了端口转发？

您正在使用 NAT 进行网络连接，如果没有端口转发，您将无法连接到客户操作系统
