如何使用仅主机网络从 VirtualBox 上的远程来宾服务器 SSH apache 用户?

如何使用仅主机网络从 VirtualBox 上的远程来宾服务器 SSH apache 用户?

我在 VirtualBox 上有两个 CentOS 虚拟机。其中之一假设 CentOS-1 保存着我的 Web 应用程序代码。其次是CentOS2。我在这两台服务器之间有两个网络连接:桥接和仅主机。

CentOS-1 : for Bridged connection the ip is : 192.168.0.137
for Host-only connection the ip is : 192.168.1.137

CentOS-2 : for Bridged connection the ip is : 192.168.0.101
for Host-only connection the ip is : 192.168.1.101

当我尝试像这样进行 ssh 时,在我的 php 网页中:

 exec('ssh -p 22 [email protected] 2>&1 ',$output);

它正在工作,但是当我尝试 ssh 到仅主机网络 ip 时:

 exec('ssh -p 22 [email protected] 2>&1 ',$output);

我得到这个作为输出:

ssh: connect to host 192.168.1.101 port 22: No route to host

我尝试重新生成 192.168.0.137 的公钥并将其复制到 192.168.0.101,但没有帮助。我还尝试授予 apache 用户权限:

在 CentOS-2 上:

sudo -u apache ssh [email protected] "pwd"
sudo -u apache ssh [email protected] "pwd"

在 CentOS-1 上:

sudo -u apache ssh [email protected] "pwd"     
sudo -u apache ssh [email protected] "pwd"

这两种方法都不起作用。我有什么遗漏的吗?的输出ifconfig -a

答案1

答案如下:

在 CentOS1 上:

sudo ifconfig eth1 192.168.1.191 netmask 255.255.255.0 up
sudo touch /etc/sysconfig/network-scripts/ifcfg-eth1 
sudo vi /etc/sysconfig/network-scripts/ifcfg-eth1  

DEVICE="eth1"
IPADDR=192.168.1.191
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"

然后:

sudo ifup eth1

在 CentOS1 上通过 ssh 连接到该服务器:

sudo -u apache ssh [email protected]"pwd"

然后apache可以ssh到192.168.1.191,你可以做任何你想做的事:)
