From the LiveJournal user account (or whatever user is running LJ), you need to
|
|
install some crontabs. These are periodic commands that run and manage your
|
|
LiveJournal installation.

<screen><prompt>$</prompt> <userinput>crontab -e</userinput></screen>

<note>

<para>This will bring up either your <envar>$EDITOR</envar>, or <application>vi</application>.
|

If you want to set your editor explicitly, do:

<screen><prompt>$</prompt> <command>EDITOR=<replaceable>pico</replaceable> crontab -e</command></screen>

Now, enter the following stuff between the dotted lines below. Not all of it is necessary.
|
|
See the comments below. The <literal>LJHOME=</literal> line is required. See the section
|
|
above about how the <envar><link linkend='lj.install.ljhome'>$LJHOME</link></envar> environment
|
|
variable is required everywhere. This is another place.

If query buffering is off, you can still run that, but it's not needed.
|
|
Packagers should make their packages install it, since it doesn't hurt if it's
|
|
running and not used. It'll die off right away if it realizes it's not needed.
|
|
Otherwise it'll start up in the background and run every 10 seconds or so.
|
|
Future startups by cron will only make sure it hasn't died (like if the database dies).
