VMware Workstation下centOS互联

目标

1. 修改配置文件，使之可以与主机及外网互联
2. 启用sshd服务，使用SecureCRT连接centOS

VMware Workstation网络配置

点击菜单 Edit > Preferences，点击NAT Settings

配置网关IP，一般默认即可，也可以自己修改

注：下面的CentOS中会用这里配置的网关、子网掩码

查看本机的DNS IP

注：下面的CentOS中会用这里DNS IP

CentOS网络配置

[[e-mail] /]# cd /etc/sysconfig/network-scripts/ #切换至network-scripts目录下
[[e-mail] network-scripts]# vi ifcfg-ens33 #编辑ifcfg打头的文件

修改

BOOTPROTO=static #动态为dhcp
ONBOOT=yes #原先为no

添加

IPADDR=192.168.123.130 #设置IP地址
GATEWAY=192.168.123.2 #设置网关
NETMASK=255.255.255.0 #设置子网掩码
DNS1=192.168.0.1 #设置DNS
DNS2=8.8.8.8 #google提供的免费DNS服务器的IP地址
DNS3=8.8.4.4 #google提供的另一个免费DNS服务器的IP地址

一切正常后，便可以通过远程工具SecureCRT连接centOS。

如何在VMware Workstation下安装centOS可以参照 VMware Workstation 14安装Centos 7
