How to solve centos cannot find ifcfg configuration file

How to solve the problem that centos cannot find the ifcfg configuration file?

After installing the CentOS 7 system on the virtual machine, when configuring communication with the host, use ifconfig to check whether there is an eth0 network card (it may also only have a loopback network card lo), so check the eth0 network card configuration file, it was found that there is no ifcfg-eth0 network card configuration file in the /etc/sysconfig/network-scripts/ directory.

The specific steps are as follows:

ls  /etc/sysconfig/network-scripts/

Some people may not have this file, then we can use

Close NetworkManager service

  $ service NetworkManager stop

Close NetworkManager and start up

 $ chkconfig NetworkManager off

mkdir ifcfg-eth0

After creating the file, we need to write the corresponding host IP into it

The specific configuration information written is as follows

DEVICE="eth0"
BOOTPROTO="static"   #设置为静态ip地址
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="ce22eeca-ecde-4536-8cc2-ef0dc36d4a8c"
IPADDR=172.16.4.22  #修改为自己的ip地址
PREFIX=24
NETMASK=255.255.254.0  #修改为自己的子网掩码
GATEWAY=192.168.0.1    #修改为自己的网关
DNS1=192.168.0.1       #修改为自己的dns
DEFROUTE=yesIPV4_FAILURE_FATAL=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME="System eth0"
HWADDR=00:0C:29:3C:BF:E7
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
LAST_CONNECT=1501853614

After we complete the modification. Just write it into it

vi /etc/sysconfig/network-scripts/ifcfg-eth0

After opening it, press i on the keyboard to enter the writing mode

Just write the modified configuration file above
