Setup Mercurial server with multiple repositories on OpenSUSE

2012-02-13T20:39:02+00:00

This tutorial is to configure a Mercurial/hg server for multiple repositories on OpenSUSE. Be sure to follow these steps on the server you want to host the repositories on.

First make sure Mercurial is installed

zypper install hg

Now create a location for the repositories

mkdir -p /var/hg/repos

Create some project as an example

cd /var/hg/repos
hg init super_proj

Create a config file for hg to know to what to serve (details here). In /var/hg/hg_repos.conf insert the following

[paths]
/ = /var/hg/repos/*

[web]
push_ssl = false
allow_push = *

Now for a startup script (based on this). In /etc/init.d/hg_serve put the following

#! /bin/sh
#
# Startup script for mercurial server.
#
### BEGIN INIT INFO
# Provides:       hg server 
# Required-Start: $local_fs $remote_fs $syslog $network 
# Required-Stop:  $local_fs $remote_fs $syslog $network
# Should-Start:   $time sendmail httpd2 xntpd $named cron ndo2db
# Should-Stop:    sendmail ndo2db
# Default-Start:  3 5
# Default-Stop:   0 1 2 6
# Short-Description: hg server 
# Description:    hg server
### END INIT INFO
# Change following ines
APP_BIN=/usr/bin/hg
SRC=/var/hg/repos
# Path to PID file of running mercurial process.
PID_FILE=/var/hg/hg.pid
CONFIG_FILE=/var/hg/hg_repos.conf

state=$1

case "$state" in
'start')
    echo "Mecurial Server service starting."
   ${APP_BIN} serve --webdir-conf=$CONFIG_FILE -d -p 8001 --pid-file ${PID_FILE}
  ;;

'stop')
  if [ -f "${PID_FILE}" ]; then
    PID=`cat "${PID_FILE}"`
    if [ "${PID}" -gt 1 ]; then
      kill -TERM ${PID}
      echo "Stopping the Mercurial service PID=${PID}."
    else
      echo Bad PID for Mercurial -- \"${PID}\"
    fi
  else
    echo No PID file recorded for mercurial
  fi
  ;;

'restart')
  $0 stop
  $0 start
  ;;

*)
  echo "$0 {start|stop|restart}"
  exit 1
  ;;
esac

Now to finalize things

chmod +x /etc/init.d/hg_serve
chkconfig --add hg_serve
service hg_serve start

(If you are using Debian/Ubuntu, to activate the script run "update-rc.d hg_serve defaults")

Now you should be able to access the server via the web. Just point your web browser to http://<your server ip>:8001

Keep in mind, this setup is for internal servers. Refer to other resources for securing your data!

SSH Keys HOWTO

2006-06-08T15:47:42+00:00

To log into a remote machine from a local machine

   1. Check your home directory in the local machine for a .ssh directory. If it's there, look inside for a file named identity.pub or id_rsa.pub. If neither exists, type ssh-keygen -t rsa
      Just press enter for passphrase, unless you want one. This creates a 1024 bit RSA version 2 keypair (other options for other types) in $HOME/.ssh/identity and $HOME/.ssh/identity.pub, OR in $HOME/.ssh/id_rsa and $HOME/.ssh/id_rsa.pub

   2. Put a copy of identity.pub or id_rsa.pub (whichever you have) into your home directory on the remote machine:
      scp $HOME/.ssh/identity.pub user@remote.machine.com:.
      (note the ending dot on the line above, it means "same filename")

   3. ssh into the remote box with a password, then do this:
      Check to see if you have a .ssh directory there. If not,
      mkdir .ssh
      chmod 750 .ssh

   4. If there is no file in the .ssh directory named authorized keys:
      cp identity.pub .ssh/authorized_keys
      or
      cp id_rsa.pub .ssh/authorized_keys
      chmod 600 .ssh/authorized_keys

      If .ssh/authorized_keys already exists: cat identity.pub >> .ssh/authorized_keys or
      cat id_rsa.pub >> .ssh/authorized_keys

   5. Now log out of the remote machine and ssh into it again. You should be logged into your account on the remote machine without having to type a password.

linux disk copy

To copy from one disk to another and preserve permissions do the following:

cd /dir/to/copy
tar -cf - * .[A-z]* | tar -C /mnt/new -xvf -
