CentOS7 no solution to ifconfig this command after minimal installation

A few days ago I minimized installed a bit of CentOS7, entered the system found no ifconfig This network configuration work, and want to rush to the Internet, how to do it. Here are the workarounds I've given:

1. Configure the Yum source with light drive, install Net-tools this package (or use RPM command).

1.1, the CentOS default Yum source in addition (CENTOS-MEDIA.REPO) moved to a specified directory, I was in the Yum source configuration file to build a directory called Repo, the following is the specific operation:

    [[email protected] ~]# cd /etc/yum.repos.d/         [[email protected] yum.repos.d]# ls     Centos-base.repo  centos-cr.repo  centos-debuginfo.repo  centos-fasttrack.repo   CentO    S-Media.repo  CentOS-Sources.repo   centos-vault.repo    [[email protected] yum.repos.d]# mkdir repo     [[email protected] yum.repos.d]# ls    centos-base.repo   CentOS-Debuginfo.repo  CentOS-Media.repo    CentOS-Vault.repo     centos-cr.repo    centos-fasttrack.repo  centos-sources.repo   repo    [[email protected] yum.repos.d]# mv *.repo  Repo/    [[email prOtected] yum.repos.d]# ls    repo    [[email protected]  yum.repos.d]# cd repo/    [[email protected] repo]# ls     CentOS-Base.repo  CentOS-CR.repo  CentOS-Debuginfo.repo   CentOS-fasttrack.repo  CentO    S-Media.repo   centos-sources.repo  centos-vault.repo    [[email protected] repo]#  MV CENTOS-MEDIA.REPO&NBSP, .... /    [[email protected] repo]# ls    centos-base.repo   centos-cr.repo  centos-debuginfo.repo  centos-fasttrack.repo  cento     S-Sources.repo  CentOS-Vault.repo    [[email  PROTECTED] REPO]# CD&NBSP, ....     [[email protected] yum.repos.d]# ls &nbSp;  centos-media.repo  repo 

1.2, mount the optical drive configuration yum source of the specific steps:

    [[email protected] yum.repos.d]#  Mount /dev/sr0 /media/        mount: /dev/sr0 is  write-protected, mounting read-only     #以上是挂载光驱的命令和操作步骤          [[email protected] yum.repos.d]# cat CentOS-Media.repo      [c7-media]    name=centos-$releasever  - Media     baseurl=file:///media/    gpgcheck=1    enabled=1     gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7        #以上光驱yum源的配置文档         [[email protected] yum.repos.d]#  yum list | wc -l    3776     #用yum   List to see if there is a problem testing the Yum source 

1.3. Install Net-tools kit with Yum

    [[email protected] yum.repos.d]# yum install net-tools - y        loaded plugins: fastestmirror, langpacks     Loading mirror speeds from cached hostfile     resolving dependencies    --> running transaction check     ---> Package net-tools.x86_64 0:2.0-0.17.20131004git.el7 will be  INSTALLED    --> FINISHED DEPENDENCY RESOLUTION   &NBSP, ..... .........    running transaction      installing :  net-tools-2.0-0.17.20131004git.el7.x86_64                                                                                       1/1        Verifying  : net-tools-2.0-0.17.20131004git.el7.x86_64                                                                                        1/1     Installed:       net-tools.x86_64 0:2.0-0.17.20131004git.el7                                                                                                            complete!

1.4. Test ifconfig Command

[[email protected] yum.repos.d]# ifconfig    eno16777736: flags=4163 <UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500             inet 192.168.1.131  netmask 255.255.255.0   Broadcast 192.168.1.255            inet6  fe80::20c:29ff:fe2d:c130  prefixlen 64  scopeid 0x20<link>             ether 00:0c:29:2d:c1:30   txqueuelen 1000   (Ethernet)              RX packets 53366  bytes 3890372  (3.7&NBSP;MIB)              RX errors 0  dropped 0   overruns 0  frame 0 &Nbsp;          tx packets 47832  bytes  22949340  (21.8&NBSP;MIB)             tx  errors 0  dropped 0 overruns 0  carrier 0   Collisions 0        lo: flags=73<up,loopback,running>   mtu 65536            inet  127.0.0.1  netmask 255.0.0.0             inet6 ::1  prefixlen 128  scopeid 0x10

2, in Linux in addition to ifconfig This command can configure the IP address and a command is IP (I use this method).
    [[email protected] yum.repos.d]# ip addr l eno16777736     2: eno16777736: <broadcast,multicast,up,lower_up> mtu 1500  qdisc pfifo_fast state UP qlen 1000         link/ether 00:0c:29:2d:c1:30 brd ff:ff:ff:ff:ff:ff         inet 192.168.1.131/24 brd 192.168.1.255 scope global eno16777736            valid_lft forever preferred_lft  forever        inet6 fe80::20c:29ff:fe2d:c130/64 scope  link            valid_lft forever  Preferred_lft forever    [[email protected] yum.repos.d]# ip addr  add 192.168.1.131/24 dev eno16777736 
IP This command and profound is not one or two words can be explained, in the future when the network learning I will give you a detailed and serious explanation, and then to everyone mention about the network card, after CentOS7 the default network card type identifier of eno16777736, in the previous system for ETHN. 
Hope this article is helpful to everyone, there is no understanding of the place, I hope you have a lot of advice. qq:87736754
