VMware中CentOS7 设置静态IP

Posted 2022-06-21 在奋斗的大道

第一步 打开windows命令行，查看本地网络情况：ipconfig

 第二步：虚拟机网络设置为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_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

如果两者的IP相同，也会导致SSH无法正常连接。
