On boot adjustment for /etc/hosts [message #28460]

We need to adjust the /etc/hosts file during reboot. OpenVZ has default settings, for example:

127.0.0.1 localhost.localdomain localhost
# Auto-generated hostname. Please do not remove this comment.
192.168.0.247 test2

What we want is that this is automatically set to, for example:

127.0.0.1 localhost test2.domain.com test2 localhost.localdomain
# Auto-generated hostname. Please do not remove this comment.
192.168.0.247 test2

Can someone tell me how can do this?

Kind regards,
Jurgen

Hi,

I'm afraid it is impossible to do without changing VPS initialization scripts.
We should distinguish between 127.0.0.1 and other IP address.
If you add appropriate record before "# Auto-generated hostname. Please do not remove this comment." string you don't loose it after reboot but that it's not true if you want to save something like that "127.0.0.1 ...".
Briefly speaking, there are some problems with 127.0.0.1 and /etc/hosts file, for example
http://bugzilla.openvz.org/show_bug.cgi?id=776

So, you can fill the bug but please look for similar problem before filling it. I've done that but haven't found the same one.

Thank you very much for the assistance!

Hi,

try this workaround.

1. Please take the latest version of vzctl.
2. Start your VPS.
3. Change /etc/hosts with your need.
4. Stop the VPS and then just comment or remove the string "HOSTNAME="test2"" from /etc/vz/conf/VEID.conf file.

After these manipulations /etc/hosts file inside VPS shouldn't be changed.
