This is a quick-and-dirty Slackware Vserver Howto as I haven't seen anything about vserver on slack. The advantage of this approach is that you can easily setup new vsevers and keep all of them up to date with the slackware packaging system, with just a few commands. There is also a portuguese[1] version of this howto.
Note that this howto is a from scratch way to do the job, there's a tool called [simplepkg] that uses templates do create vservers and have some scripts to keep all the jails updated. |
| Create a default skeleton for your vserver's config (skel.conf) and put it the the same dir of the scripts. |
|
Create a default skeleton for your vserver's config (skel.conf) and put it the the same dir of the scripts. You'll also need a tgz file with a small /dev folder containing the following devices/subfolders:
<code> crw-r -rw-r srw-rw-rw- 1 root root 0 2005-07-23 09:35 log crw-r crw-r drwxr-xr-x 2 root root 0 2005-07-22 18:28 pts crw-r crw-r crw-r crw-r </code> |

=== Config format ===
If you're using the new configuration method for your vservers and want to use the sysv init style, you should create the following /etc/rc.d/rc script inside your vserver: <code> #!/bin/bash if [ "$1" == "3" ]; then /etc/rc.d/rc.M elif [ "$1" == "6" ]; then /etc/rc.d/rc.6 else echo "Invalid level." exit 1 fi </code> === Passive FTP === |
