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 ad different run levels through the "chkconfig" tool.

 # samba4       Bring up/down samba4 service

 #              start at boot time.
