Q

Hi,

I have configured static IP address (192.168.1.23). But everytime i boot up, its picking another IP address. (192.168.1.100).

But after the boot up, if i give 'service network restart' it gets changed to my static IP. If the network is not restarted, its with its own (192.168.1.100). If i check the ifcfg-eth0 file, i see the IP which i have given.

How to fix it?

Regards,
Clement

how to change linux centose ip address

Hi Clement,

I have similar problem , everytime I reboot its pickingip another IP. Is your problem resolved? have you found reason?

Regards,

Check below link if someone still have issues with static ip on centos 6.
https://gist.github.com/keshara/2f50045430ab193006af

Based on a Redhat network config, I simply added the DNS by adding the following extra lines to /etc/sysconfig/network-scripts/ifcfg-eth0. Then after restarting the network I already had the correct values in /etc/resolv.conf.

Thank you!

Hey declum/unikhil,

I had the same issue but managed to resolve it. The service NetworkManager appears to override any configurations made in /etc/sysconfig/network-scripts. A couple of remedies:

1. Add the line NM_CONTROLLED=no to the config file.. or

2. Disable network manager by

Thanks!!!

Thanks! Need to create my own note :)

Thanks! Helped a lot.

Thank you so much.

Great! Thanks for share!

Thanks

Great!
it's work confirm!!!!

thanks

Wow you don't know how much I did battle with a broken set-up because of bad advice.
Because of this write-up it now works beautifully.
Thank you!

Thanks.

I must say when I started configuring static IP's on Cent OS 7 via CLI it was pretty confusing, but then i understood it - it became much easier. Without need to disable Network Manager, just type this command “nmtui” to open Network manager and edit any connection. This is super easy and no VI , NANO are needed. Plus can reset adapter too. Hope this will help others as well. Regards!

Thanks, It's helpful to me.

How about /etc/hosts file which has reference to server along with alias?

@Azhung I had the same issue but fixed it by adding the line GATEWAY=10.0.1.1 (Replacing with your correct gateway, of course) to /etc/sysconfig/network-scripts/ifcfg-eth0

Can't figure it out. Seems to have a problem setting the IP. I'm trying to set it to 192.168.1.223

Thank you

Thank you. :-)

Thanks!!!!

Muchas gracias - been using this for a long time as reference for static IP. Rock on!

Thank you very much!

thank you.

Thank you so much 👍 :D

For IP ranges you can also use my scirpt: https://github.com/jonsbun/add-ips-centos

@Arinerron: set up your default gateway, no gateway, your systems only knows your local network (192.168.1.x/y). Furthermore you should use ip add sh, instead of ifconfig nowadays.

OMG THANK YOU! Spent half a day trying to figure out how to create a static IP on CentOS. this took me 5 mins to do.

Make sure to refer to /usr/share/doc/initscripts-*/sysconfig.txt (search for /etc/sysconfig/network-scripts/ifcfg) - that's the only built-in documentation for this mechanism.

Okay so dumb question that I probably don't need to worry about, is there a difference when you do ONBOOT=yes versus ONBOOT='yes' with quotes? I get using quotes if there's a space in it like your example of NAME='System eth0' but does it matter for one word entries like yes or no?

I have done all the things as guided but still internet is not working, on using ping command it says unknown hosts: . I did exactly same as asked.please do help me.i tried almost everything.

Thank you so much :)

its nice thank u
