Samba4/InitScript

From SambaWiki
Jump to: navigation, search

This is a topic which pops every so often -- where are the Init scripts for Samba4? The problem is that init scripts are very distribution specific. The HOWTO states, "Samba4 alpha13 doesn't yet have init scripts included for each platform, but making one for your platform should not be difficult." Well, they may not be rocket science, but not everyone knows how to build a robust startup script and then integrate it with their particular startup infrastructure. This gets even more weird when distributions like Fedora radically overhaul their approach to init. (SysV to "systemd")

The intent of this page is to provide a sample of at least a few init scripts, listed by their distribution family (eg., Debian based systems and Red Hat/Fedora).

Red Hat/Fedora based systems

For SysV style service init scripts, Red Hat puts the init scripts in the /etc/rc.d/init.d directory, and then links to these scripts from the various run level directories (eg, link in /etc/rc3.d/S80samba4 -> ../rc.d/init.d/samba4)

Fedora has gone to a systemd based startup for Init. You can still use SysV style scripts such as this one, and configure the automatic startup of the Samba4 server and different run levels through the "chkconfig" tool.

#!/bin/bash
#
# samba4        This shell script takes care of starting and stopping
#               samba4 daemons.

# over Samba 3.6 are support for the Active Directory logon protocols
# used by Windows 2000 and above.

Debian Systems

1) Retrieve the init script

To retrieve the Debian init script, run:

  $ wget "http://anonscm.debian.org/gitweb/?p=pkg-samba/samba.git;a=blob_plain;f=debian/samba.samba-ad-dc.init;h=3132d2e367675f822342a5b7bc2e50c046aa3b8f;hb=HEAD" -O /etc/init.d/samba-ad-dc

2) (Optional) Update the paths where Samba is installed

The Debian package assumes that Samba is installed in /usr. If you've installed it in the default location (/usr/local/samba) instead, run:

  $ sed -i 's|/usr/sbin|/usr/local/samba/sbin|g' /etc/init.d/samba-ad-dc

Likewise the Debian package assumes you'll use /etc/samba/smb.conf for the configuration file. If you're using the default location and build run:

  $ sed -i 's|/etc/samba|/usr/local/samba/etc|g' /etc/init.d/samba-ad-dc

Again, the Debian package assumes you'll use /var/run/samba as pid directory. If you're using the default location, run:

  $ sed -i 's|/var/run/samba|/usr/local/samba/var/run|g' /etc/init.d/samba-ad-dc

Last, if you're using the default location for samba-tools, run :

  $ sed -i 's|samba-tool|/usr/local/samba/bin/samba-tool|g' /etc/init.d/samba-ad-dc

3) Make the init script executable

Make the init script executable by running:

  $ chmod 755 /etc/init.d/samba-ad-dc

4) Enable the script at startup

  $ update-rc.d samba-ad-dc defaults

Upstart Systems (such as Ubuntu)

Ubuntu uses the upstart system. To retrieve the upstart config file, run:

  $ wget -O /etc/init/samba-ad-dc.conf 'http://anonscm.debian.org/gitweb/?p=pkg-samba/samba.git;a=blob_plain;f=debian/samba-ad-dc.upstart;hb=HEAD'

The following init script will start a source installed NON AD samba server. i.e 'classic' mode:

#!/bin/sh

# Default-Stop:      0 1 6
# Should-Start:      slapd
# Should-Stop:       slapd
# Short-Description: start Samba daemons (nmbd and smbd)
### END INIT INFO

# Description of this script:
#                    
# This script comes initially from a Debian Squeeze machine on
# which samba 3.x was installed with "apt-get install samba". The script
# was modified/adjusted so it points to the correct paths of a default
# samba4 installation (/usr/local/samba).
#
# Installation instructions:
# (1) copy the content of this script into your clipboard or download it
# (2) save the content into /etc/init.d/samba of your samba4 host.
# (3) execute "chmod +x /etc/init.d/samba" to have the script executable
# (4) execute "update-rc.d samba defaults" to install auto-start function.
#     smbd+nmbd will automatically being started after earch system start/reboot
