本文档记录了在CentOS7系统中如何查看和配置网络接口ens33的静态IP，包括修改`ifcfg-ens33`文件，设置IP地址、子网掩码和网关，并检查防火墙状态。同时，展示了主机VMware的VMnet8网络设置及DHCP和NAT配置。

1.起因：ifconfig无问题，此处可以看到网卡使用的是`ens33`


[root@localhost ~]# ifconfig
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 0.0.0.0

2. centos 7 查看防火墙命令：

[root@localhost /]# systemctl status firewalld.service 
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

dead为关闭状态

进入到 /etc/sysconfig/network-script下,ls查看

[root@localhost /]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls
ifcfg-ens33   ifdown           ifdown-eth   ifdown-isdn    ifdown-sit     ifup-TeamPort  ifup-ib    ifup-plip   ifup-routes    init.ipv6-global
ifcfg-ens33~  ifdown-Team      ifdown-ib    ifdown-post    ifdown-tunnel  ifup-aliases   ifup-ippp  ifup-plusb  ifup-sit       network-functions
ifcfg-ens3z~  ifdown-TeamPort  ifdown-ippp  ifdown-ppp     ifup           ifup-bnep      ifup-ipv6  ifup-post   ifup-tunnel    network-functions-ipv6
ifcfg-lo      ifdown-bnep      ifdown-ipv6  ifdown-routes  ifup-Team      ifup-eth       ifup-isdn  ifup-ppp    ifup-wireless
[root@localhost network-scripts]#

然后vim编辑ifcfg-ens33

[root@localhost network-scripts]# vim ifcfg-ens33

ifcfg-ens33内容如下：
里面有几项需要需要改：
BOOTPROTO=static，代表ip固定
ONBOOT=yes，代表开机启动
IPADDR=“192.168.88.188”，代表你自定义的IP，网段取决于你VM网络设置的网段。
NETMASK=255.255.255.0需要跟Vm虚拟设置中的子网掩码相同，具体来源还是主机的子网掩码，可以到主机cmd ipconfig查看，如还没配好主机的Vmnet8配置，则需要先看第3步。
HWADDR=“00:0C:33:59:Dd:11” 则在右键虚拟机-->虚拟机设置-->网络适配器-->高级。如图

在这里插入图片描述

IPV6_ADDR_GEN_MODE="stable-privacy"

DEVICE="ens33"
ONBOOT="yes"
IPADDR="192.168.88.188"
NETMASK="255.255.255.0"
GATEWAY="192.168.88.2"
HWADDR="00:0C:33:59:Dd:11"
