CentOS7 Configuring the network card virtual machine Mount CD set up local Yum source Modify host Name

Environment: VMware System: centos-7.0-1406-x86_64-everything

First, configure the network card

1. vim/etc/sysconfig/network-scripts/ifcfg-eno16777736

   CENTOS7 network card name with the previous CENTOS6 name has a relatively large change, the original rules of the ETH0,ETH1 name Wood has!!

   It looks awkward, so it's good to use table completion when editing the NIC

2. Modify the configuration

Type=ethernet

Bootproto=static

name=eno16777736

Onboot=yes

ipaddr=192.168.110.10

netmask=255.255.255.0

IPADDR represents address netmask Subnet Mask Gateway Gateways DNS1 basically the same as the previous name

System default NIC not booting to change the onboot to Yes

3. Start the network card

Mode 1.service network Start|restart usage in CENTOS6

Way 2.systemctl Restart Network.service

4. View the network card

If you use the most basic installation, you may not have the ifconfig command to use IP addr to view the ping test final confirmation

Second, mount the disc configuration local Yum source

2. Mount Disc MOUNT/DEV/SR0/MNT

4. Cd/etc/yum.repo.d/addresses are backed up

   Centos-base.repo.bak Centos-debuginfo.repo.bak Centos-sources.repo.bak Centos-vault.repo.bak such a son

6. Create a Yum source directory

   Vim Myrepo.repo

   and add the path to the Yum source

   [Myrepo]

   name=centos-$releasever-myrepo

   Baseurl=file:///mnt

   Gpgcheck=0

   Enabled=1

   Gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-centos-5

8. Installation test is yum-y install tree

Three. Modify the host name

1.vim/etc/hostname Save reboot login hostname visible Change host name
