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

打个补丁

昨天上述方法管用，结果虚拟机开一晚上，早上又没有IP了，方法也不管用，查了下解决方法，如下
原文章：修改ens33ip时出现ip configuration could not be reserved (no available address timeout etc.）的解决方案。

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

将BOOTPROTO=dhcp改为none

重启网卡nmcli connection reload 网卡名
