在ip地址为：192.168.1.27的机器上，安装虚拟机，供其他机器使用。

下图是我远程桌面连接192.168.1.27机器。

1.27机器很干净。只有虚拟机、启动脚本、nginx停止脚本。

## win\_start.bat文件 ##

cd C:\Users\tingyun\Desktop\nginx-1.20.0\
    
    start nginx.exe
    
    cd C:\Users\tingyun\Desktop\nginx-1.20.0 -23
    
    start nginx.exe
    
    cd C:\Users\tingyun\Desktop\nginx-1.20.0 -24
    
    start nginx.exe
    
    "C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe" -T ws start "C:\Users\tingyun\Documents\Virtual Machines\Grafana\Grafana.vmx" gui
    
    "C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe" -T ws start "C:\Users\tingyun\Documents\Virtual Machines\Agent\Agent.vmx" gui  
    
    "C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe" -T ws start "C:\Users\tingyun\Documents\Virtual Machines\Promethus\Promethus.vmx" gui

### stop\_nginx.bat文件 ###

cd C:\Users\tingyun\Desktop\nginx-1.20.0\
    
    nginx -s quit
    
    cd C:\Users\tingyun\Desktop\nginx-1.20.0 -23
    
    nginx -s quit
    
    cd C:\Users\tingyun\Desktop\nginx-1.20.0 -24
    
    nginx -s quit

## 虚拟机 ##

克隆了三个centos虚拟机。

网卡使用的是NAT模式。

这样启动，外部是无法访问到虚拟机中centos系统的

那我们应该怎么办呢？

## 解决办法 ##

使用nginx进行映射。可以解决这个问题。

### nginx.conf文件（完整文件） ###

其他的nginx文件都有缩减。

### nginx.conf配置文件解析 ###

配置文件如下：

### nginx02 ###

stream{
        upstream as_socket{
            server 192.168.157.135:22;
        }
        server{
            listen 23;
            proxy_pass as_socket;
        }
    }

### nginx03 ###

stream{
        upstream as_socket{
            server 192.168.157.134:22;
        }
        server{
            listen 24;
            proxy_pass as_socket;
        }
    }

### 连接 ###

连接的时候，ip地址相同，但端口不同

Promethus	192.168.1.27  22端口
    Agent		192.168.1.27  22端口
    Grafana		192.168.1.27  22端口
