Difference between revisions of "Installation on Slackware 14"

Revision as of 21:26, 19 October 2012

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 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
• slackware-14.0.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 and blank otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # 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 downloaded 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 $LIST ]; then
        while read LINE
            do  
            wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
        done < $LIST
else
        echo "Can't find $LIST file."
        exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
        while read LINE
        do
                IFS='/' read -ra PKG <<< "$LINE"
                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
                                            
rm index.html*

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

./download_slack_pkg.sh

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)

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
