Basic operations in OpenVZ environment/en
This article assumes you have already installed OpenVZ. If not, follow the link to perform the steps needed.
Create and start a container[edit]
To create and start a container, run the following commands:
[host-node]# vzctl create CTID --ostemplate osname [host-node]# vzctl set CTID --ipadd a.b.c.d --save [host-node]# vzctl set CTID --nameserver a.b.c.d --save [host-node]# vzctl start CTID
Here CTID is the numeric ID for the container; osname is the name of the OS template for the container, and a.b.c.d is the IP address to be assigned to the container.
Example:
[host-node]# vzctl create 101 --ostemplate fedora-core-5-minimal [host-node]# vzctl set 101 --ipadd 10.1.2.3 --save [host-node]# vzctl set 101 --nameserver 10.0.2.1 --save [host-node]# vzctl start 101
Your freshly-created container should be up and running now; you can see its processes:
[host-node]# vzctl exec CTID ps ax
Enter to and exit from the container[edit]
To enter container give the following command:
[host-node]# vzctl enter CTID entered into container CTID [container]#
To exit from container, just type exit and press Enter:
[container]# exit exited from container VEID [host-node]#
Stop and destroy the container[edit]
To stop container:
[host-node]# vzctl stop CTID Stopping container ... Container was stopped Container is unmounted
And to destroy container:
[host-node]# vzctl destroy CTID Destroying container private area: /vz/private/CTID Container private area was destroyed
Now, when you know how to manage your container, learn about Resource management.
