centos虚拟机无法联网

centos虚拟机安装完毕后无法联网

进入目录/etc/sysconfig/network-scripts/

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

修改文件ifcfg-ens33(各自的不太一样)

vi 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=34491754-147a-453f-b5b1-089f3d6a7632
DEVICE=ens33
ONBOOT=no

修改ONBOOT为yes，保存

最后重启网络, systemctl restart network
