Let me just preface this post by saying “This is not a persistent configuration. If you boot the system, these settings will be lost unless you save them via the \/etc\/sysconfig\/network-scripts files or through NetworkManager.<\/p>\n
Here is how you can manually configure the IP address and gateway in CentOS\/RHEL7:<\/p>\n
Configure the IP address and subnet mask:<\/p>\n
# ip addr add aaa.bbb.ccc.ddd\/ss<\/em> dev interface<\/em><\/p><\/blockquote>\n
For example:<\/p>\n
# ip addr add 123.123.123.123\/24 dev eno1<\/p><\/blockquote>\n
Likewise, to remove the IP address:<\/p>\n
# ip addr del <\/strong>123.123.123.123\/24 dev eno1<\/p><\/blockquote>\n
To configure the default gateway:<\/p>\n
# ip route add default via ddd.ccc.bbb.aaa<\/em> dev interface<\/em><\/p><\/blockquote>\n
For example:<\/p>\n
# ip route add default via 123.123.123.254 dev eno1<\/p><\/blockquote>\n
Same kind of thing to remove the currently configured gateway:<\/p>\n
# ip route del default via 123.123.123.254 dev eno1<\/p><\/blockquote>\n
Once you have the interface configure, bring it up:<\/p>\n
# if link set eno1 up<\/p><\/blockquote>\n
And to take it down:<\/p>\n
# if link set eno1 down<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
