Revision as of 14:31, 29 December 2013
The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1** (both 32b and 64b). I will assume that you have a Linux-Vserver box working.
Contents |
Download
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz tar xzf slack_vserver.tar.gz cd slack_vserver ls
You have downloaded the following files:
- PKG_LIST is the package list to be installed in the guest
- download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
- make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
- rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
- linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.
Download the packages
First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.
I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.
You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages or empty otherwise, while $VERSION is the Slackware version, so it's something like "14.1".
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

fi
# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then

fi

cd $PACKAGES
if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
# download packages from the patches folder
cd ${PACKAGES}/patches
if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.
Make the guest
Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.
This is done adjusting and running the script make_slack_vserver.sh:
#!/bin/bash

#
# This script installs a Slackware guest into a linux-vserver host (http://linux-vserver.org)
#
# Comments are welcome :-)

Note that /etc/resolv.conf /etc/localtime /etc/profile are copied form the host.
Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
./make_slack_vserver.sh
Apply the patch
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
cd /vservers/vserver_name/etc/rc.d patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.
Post installation tasks
Put this inside your rc.local:
/usr/local/etc/rc.d/init.d/vprocunhide start
Start the new server
vserver <vserver_name> start vserver <vserver_name> enter
Patch applayed
