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 </pre> <hr> <a href="#sysv">How to use with sysvinit and inittab</a><br> <a href="#upstart">How to use with sysvinit and upstart</a><br> <a href="#bsd">How to use with *BSD init</a><br> <a href="#macosx">How to use with MacOSX init</a> <hr> <a name="sysv"><h2>Using with sysvinit and inittab</h2></a> 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. <hr> <a name="macosx"><h2>Using with MacOSX init</h2></a> 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 </pre> <hr> <address><a href="mailto:pape@smarden.org"> Gerrit Pape <pape@smarden.org> </a></address> </body> </html>
