CentOS 7 Change Network Interface Name From Eno* To Eth0<\/strong><\/p>\n

After you installed CentOS 7.0 or RHEL 7.0 system, you maybe notice that the default name of network interface was changed from \u201cEth*\u201d to \u201cEno*\u201d. How do I change network interface name to \u201cEth0? in CentOS 7.0? This post will show you the ways to change network interface.
\nCentOS 7 Change Network Interface Name
\nStep1# issue the ifconfig command to check the current network interface information, type:
\n# yum install net-tools<\/p>\n

[root@localhost Desktop]$sudo ifconfig
\neno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
\ninet 192.168.42.129 netmask 255.255.255.0 broadcast 192.168.42.255
\ninet6 fe80::20c:29ff:fec7:25ae prefixlen 64 scopeid 0x20<link>
\nether 00:0c:29:c7:25:ae txqueuelen 1000 (Ethernet)
\nRX packets 200948 bytes 253071365 (241.3 MiB)
\nRX errors 0 dropped 0 overruns 0 frame 0
\nTX packets 56043 bytes 3420351 (3.2 MiB)
\nTX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
\nStep2# edit \u201c\/etc\/sysconfig\/grub\u201d configuration file using \u201cvim\u201d command:
\nbefore:<\/p>\n

[root@localhost Desktop]$sudo vim \/etc\/sysconfig\/grub
\nGRUB_DEFAULT=saved
\nGRUB_DISABLE_SUBMENU=true
\nGRUB_TERMINAL_OUTPUT=”console”
\nGRUB_CMDLINE_LINUX=”rd.lvm.lv=centos\/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos\/root crashkernel=auto vconsole.keymap=us rhgb quiet”
\nGRUB_DISABLE_RECOVERY=”true”
\nthen searching for \u201cGRUB_CMDLINE_LINUX\u201d line and appending the following content \u201cnet.ifnames=0 biosdevname=0\u201c, just like the below:
\n1
\nGRUB_CMDLINE_LINUX=”rd.lvm.lv=centos\/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos\/root crashkernel=auto vconsole.keymap=us rhgb quiet net.ifnames=0 biosdevname=0″
\nStep3# Using \u201cgrub2-mkconfig\u201d command to re-generate a new grub configuration file, type:<\/p>\n

[root@localhost Desktop]$sudo grub2-mkconfig -o \/boot\/grub2\/grub.cfg

\nStep4# Rename \u201cEno\u201d network file using \u201dmv\u201d command, type:<\/p>\n

$sudo mv \/etc\/sysconfig\/network-scripts\/ifcfg-eno16777736 \/etc\/sysconfig\/network-scripts\/ifcfg-eth0<\/p>\n

Step5# Edit \u201c\/etc\/sysconfig\/network-scripts\/ifcfg-eth0 \u201d configuration file and set the value of \u201cName\u201d field to \u201ceth0?.<\/p>\n

# vim \/etc\/sysconfig\/network-scripts\/ifcfg-eth0

\nStep6# reboot system, after rebooting system, using \u201cifconfig\u201d command check network interface information again.<\/p>\n
