startup script for openvz

laurens · 10-11-2009, 07:29 AM

Hi all,

First, I always look for similar topics, but weirdly enough I didn't find anything; maybe I used the wrong search terms. Anyway here's my question.

When a server running OpenVZ (host and 5 containers) is restarted, obviously the containers are restarted too. This causes to erase some important iptables configurations in one of the containers.

My solution is to run a script from the host machine every time the server (unintentionally) restarts.

the easy script should do something like this.

Code:

vzctl start 101
sleep 20 secs (?!)
vzctl exec 101 iptables add ....

My question is: where put this 'script.sh' to make sure it runs every time the server (host) is restarted?
PS: my guess is it is better to run the sript from the host instead of the container.

Thanks in advance!!

How did you install OpenVZ (assuming you installed it with hypervm since you can only have host.) If that is how you insatlled I would recommend you install openVZ then install hypervm with

Code:

sh ./hypervm-install-master.sh --virtualization-type=NONE

What system and arch did you install it on. You shouldn't lose nothing from the containers everytime you reboot. sounds like you have a misconfiguration somewhere.

OpenVZ is installed fine... I use it already months without problems. It's only the fact that iptables get reset when rebooting the openVZ host. To answer your question: I installed it via 'apt-get install openvz' on the host. Pretty easy indeed
So what I need is a location on the host to place this script (above).
Thx
