<h1>runit - use with traditional init</h1>
|
||

<hr>

|
|
It's possible to use <i>runit</i>'s service supervision without replacing
|
||
|
|
the <i>init</i> scheme of the system.
|
||
|
|
Simply run the <i>stage 2</i> of <i>runit</i> as a service with your
|
||
|
|
current <i>init</i>.
|
||
|
|
<p>
|
||
|
|
Normally this is done by either adding an entry for
|
||
|
|
<tt>/sbin/runsvdir-start</tt> to <tt>/etc/inittab</tt>, or by adding
|
||
|
|
<tt>/sbin/runsvdir-start</tt> as command to </tt>/etc/rc.local</tt>, or by
|
||
|
|
adding <tt>/sbin/runsvdir-start</tt> to the system's <tt>StartupItems</tt>.
|
||
|
|
<p>
|
||
|
|
In any case, you first need to copy the <i>stage 2</i> script to
|
||
|
|
<tt>/sbin/runsvdir-start</tt>, and create the services directory
|
||
|
|
<tt>/service/</tt>:
|
||
|
|
<pre>
|
||
|
|
# install -m0750 /package/admin/runit/etc/2 /sbin/runsvdir-start
|
||
|
|
# mkdir -p /service
|
||
|
|

|

|
|
If your system uses a sysvinit alike init scheme with a <tt>/etc/inittab</tt>
|
||
|
|
file, do:
|
||
|
|
<pre>
|
||
|
|
# cat >>/etc/inittab <<EOT
|
||
|
|
SV:123456:respawn:/sbin/runsvdir-start
|
||
|
|
EOT
|
||
|
|
</pre>
|
||
|
|
and tell <i>init</i> to re-read its configuration, e.g.:
|
||
|
|
<pre>
|
||
|
|
# init q
|
||
|
|
</pre>
|
||
|
|
<hr>
|
||
|
|
<a name="upstart"><h2>Using with sysvinit and upstart</h2></a>
|
||
|
|
If your system uses a sysvinit alike init scheme that utilizes upstart
|
||
|
|
instead of inittab, and which has start and stop scripts located in
|
||
|
|
<tt>/etc/init/</tt>, do:
|
||
|
|
<pre>
|
||
|
|
# cat >/etc/init/runsvdir.conf <<\EOT
|
||
|
|
# for runit - manage /usr/sbin/runsvdir-start
|
||
|
|
start on runlevel 2
|
||
|
|
start on runlevel 3
|
||
|
|
start on runlevel 4
|
||
|
|
start on runlevel 5
|
||
|
|
stop on shutdown
|
||
|
|
respawn
|
||
|
|
exec /usr/sbin/runsvdir-start
|
||
|
|
EOT
|
||
|
|
</pre>
|
||
|
|
and tell init to start the new service, e.g.:
|
||
|
|
<pre>
|
||
|
|
# start runsvdir
|
||
|
|
</pre>
|
||
|
|
<hr>
|

|
|
<a name="bsd"><h2>Using with *BSD init</h2></a>
|
||
|
|
If your system uses a BSD alike init scheme with a <tt>/etc/rc.local</tt>
|
||
|
|
script, do:
|
||
|
|
<pre>
|
||
|
|
# cat >>/etc/rc.local <<EOT
|
||
|
|
csh -cf '/sbin/runsvdir-start &'
|
||
|
|
EOT
|
||
|
|
</pre>
|
||
|
|
and reboot your system.

On MacOSX 10.2 create an entry for <i>runit</i> in
|
||
|
|
<tt>/System/Library/StartupItems/</tt>:
|
||
|
|
<pre>
|
||
|
|
# cd /System/Library/StartupItems
|
||
|
|
# mkdir -p runit
|
||
|
|
# cp -p /package/admin/runit/etc/macosx/StartupItems/* runit/
|
||
|
|
</pre>
|
||
|
|
and reboot your system.
|
||
|
|
<p>
|
||
|
|
On MacOSX 10.4 create an entry for <i>runit</i> in
|
||
|
|
<tt>/Library/LaunchDaemons/</tt>, and tell <i>launchd</i> to start the new
|
||
|
|
service:
|
||
|
|
<pre>
|
||
|
|
# cp /package/admin/runit/etc/macosx/org.smarden.runit.plist \
|
||
|
|
/Library/LaunchDaemons/
|
||
|
|
# launchctl load /Library/LaunchDaemons/org.smarden.runit.plist
