Step 1) add kernel boot args & regenerate the grub config<\/p>\n
The following kernel boot arguments need to be added:
\nbiosdevname=0
\n net.ifnames=0<\/p>\n
Open \/etc\/default\/grub with your favorite editor and add those two options to the line starting with GRUB_CMDLINE_LINUX:<\/p>\n
[root@apache2 ~]# cat \/etc\/default\/grub
\nGRUB_TIMEOUT=5
\nGRUB_DISTRIBUTOR=”$(sed ‘s, release .*$,,g’ \/etc\/system-release)”
\nGRUB_DEFAULT=saved
\nGRUB_DISABLE_SUBMENU=true
\nGRUB_TERMINAL_OUTPUT=”console”
\nGRUB_CMDLINE_LINUX=”crashkernel=auto rd.lvm.lv=centos\/root rd.lvm.lv=centos\/swap rhgb quiet”
\nGRUB_DISABLE_RECOVERY=”true”
\n[root@apache2 ~]#<\/p>\n
Will look like this: root@apache2 ~]# grub2-mkconfig -o \/boot\/grub2\/grub.cfg [root@apache2 network-scripts]# mv ifcfg-eno16777736 ifcfg-eth0 BOOTPROTO=”static” root@apache2 network-scripts]# systemctl stop NetworkManager Step 2) add a udev symlink, just to make sure<\/p>\n Basically adding the biosdevname=0 and net.ifnames=0 arguments to grub should be enough. But here\u2019s another way just in case:<\/p>\n [root@test ~]# ln -s \/dev\/null \/etc\/udev\/rules.d\/80-net-name-slot.rules<\/p>\n [root@apache2 ~]# ifconfig -a Disable IPv6:<\/p>\n First check that IPv6 is enabled or not: Search for the line \u201cGRUB_CMDLINE_LINUX\u201d and add the following at the beginning: \u201cipv6.disable=1?<\/p>\n Will look like this: Create a new configuration based on the currently running system using grub2-mkconfig command: Tags: biosdevname=0, default network device, GRUB_CMDLINE_LINUX, how to change network name to old eth0, net.ifnames=0, net.ifnames=0 biosdevname=0, Red Hat Enterprise Network name <\/p>\n Step 1) add kernel boot args & regenerate the grub config<\/p>\n The following kernel boot arguments need to be added: biosdevname=0 net.ifnames=0<\/p>\n Open \/etc\/default\/grub with your favorite editor and add those […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[73],"tags":[],"_links":{"self":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts\/5923"}],"collection":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=5923"}],"version-history":[{"count":4,"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts\/5923\/revisions"}],"predecessor-version":[{"id":5927,"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts\/5923\/revisions\/5927"}],"wp:attachment":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=5923"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=5923"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=5923"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
