Difference between revisions of "Installation on Slackware 14"

Revision as of 19:24, 5 January 2014

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.

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)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
    mkdir -p $PACKAGES
fi

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

# download
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:

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-14.1.patch

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, 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
