桥接模式下没有IP不能联网的问题

桥接模式下没有ip，不能联网

ifconfig 命令

ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::371b:3139:1d2b:d5cf  prefixlen 64  scopeid 0x20<link>

可以先关闭防火墙

systemctl status firewalld 查看防火墙状态

systemctl stop firewalld 关闭防火墙

systemctl start firewalld 开启防火墙

检查Linux的配置文件

命令

vim /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="dhcp"
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="da32cd0f-3c80-44bb-9840-74a28efd2940"
DEVICE="ens33"
ONBOOT="yes"

确认是否是dhcp模式,BOOTPROTO="dhcp",以及系统启动时是否执行dhcp模式,ONBOOT="yes"。

然后检查VMware的网络配置

最后重新启动网卡

Centos 8 中
nmcli connection reload 网卡名 [我是用的这个]

nmcli connection up 网卡名

nmcli device reapply 网卡名

nmcli device connect 网卡名

方法二：
ifconfig 网卡名 down 关闭网卡

ifconfig 网卡名 up 启动网卡
