1. 查看当前网卡名称 ifconfig

ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.101.77  netmask 255.255.255.0  broadcast 192.168.101.255
        inet6 fe80::2b11:164e:2b33:f3b  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:9e:19:4e  txqueuelen 1000  (Ethernet)

        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>

        inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255
        ether 52:54:00:cb:7d:4e  txqueuelen 1000  (Ethernet)

2. 设置桥接模式

3. ens33网卡对应的配置文件为ifcfg-ens33，使用vim编辑如下:

cd /etc/sysconfig/network-scripts/

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"         # 使用静态IP地址，默认为dhcp
IPADDR="192.168.101.77"   # 设置的静态IP地址
NETMASK="255.255.255.0"    # 子网掩码
GATEWAY="192.168.101.255"    # 网关地址
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="5df001d6-641c-4cce-b5d6-f1a9dd8f8356"
DEVICE="ens33"
ONBOOT="yes"
