## 第一步 打开windows[命令行][Link 1]，查看本地网络情况：`ipconfig` ##

## 第二步：[虚拟机][Link 2]网络设置为NAT模式： ##

## 第三步 打开[VMware][]虚拟网络编辑器 ##

点击NAT设置，将网关设置与无线局域网适配器WLAN一致：

## 第四步：本地网络适配器设置虚拟机虚拟网络 ##

## 第五步：centos网络配置 ##

①.打开centos网卡信息：`/etc/sysconfig/network-scripts`  
②.修改不部分配置：`vi ifcfg-ens33`

TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    BOOTPROTO=static
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=ens33
    UUID=9d1dc841-4103-41dc-a403-70bf6e3ee08d
    DEVICE=ens33
    ONBOOT=yes
    IPADDR=192.168.43.10
    GATEWAY=192.168.43.1
    NETMASK=255.255.255.0
    DNS1=192.168.43.1

## 第六步:重启 ##

重启网络服务：service network restart
    重启服务器：reboot（也可以不重启）

更新一些问题解决

1、使用MobaXterm 无法连接CentOS 服务器。

> 通过ssh -v root@ip 查看ssh 连接服务。

以下是我虚拟机centOS 服务ssh 服务状态。

SSH 服务报错日志记录：

debug1: SSH2_MSG_SERVICE_REQUEST sent
    debug1: SSH2_MSG_SERVICE_ACCEPT received
    debug1: Authentications that can continue: publickey,gssapi-with-mic,password
    debug1: Next authentication method: gssapi-with-mic
    debug1: Unspecified GSS failure.  Minor code may provide more information
    No credentials cache found

解决办法：

在 ssh 客户端程序的配置文件里显式禁用 GSSAPI 认证. 如, 编辑 /etc/ssh/ssh\_config 文件, 添加或修改使其有如下一行:

GSSAPIAuthentication no

2、VMnet8 与CentOS 静态IP 不能一直。

VMnet8 配置

CentOS 静态IP

![83e0efcdf63740c094830da810877f0e.png][]

如果两者的IP相同，也会导致SSH无法正常连接。
