vmware安裝的centos7中沒有出現(xiàn)eth0網(wǎng)卡热监，也沒有ip，不能上網(wǎng)犁柜，輸入ifconfig后如下圖
解決辦法
1.編輯網(wǎng)卡的配置文件?vi /etc/sysconfig/network-scripts/ifcfg-ens33 將里面的NAME和DEVICE項(xiàng)修改為eth0
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
BOOTPROTO=static
IPADDR=192.168.0.116
NETMASK=255.255.255.0
GATEWAY=192.168.0.115
DNS1=114.114.114.114
DNS2=8.8.8.8
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eth0
UUID=972a1eb3-049f-4db2-80f5-7d8fd28ef76f
DEVICE=eth0
ONBOOT=yes
2.重命名網(wǎng)卡配置文件ifcfg-ens33為ifcfg-eth0
[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# mv ifcfg-ens33 ifcfg-eth0
3.編輯/etc/default/grub并加入“net.ifnames=0 biosdevname=0 ”到GRUBCMDLINELINUX變量
[root@localhost network-scripts]# vi /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto net.ifnames=0 biosdevname=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"?
4.運(yùn)行命令grub2-mkconfig -o /boot/grub2/grub.cfg 來(lái)重新生成GRUB配置并更新內(nèi)核參數(shù)剖毯。
[root@localhost network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.10.0-514.el7.x86_64
Found initrd image: /boot/initramfs-3.10.0-514.el7.x86_64.img
Found linux image: /boot/vmlinuz-0-rescue-b7f83ca165964a47b8b283907b126140
Found initrd image: /boot/initramfs-0-rescue-b7f83ca165964a47b8b283907b126140.img
done
5.重啟系統(tǒng)
[root@localhost network-scripts]# reboot
6.輸入ifconfig驗(yàn)證
親測(cè)可行
