Memcache warnings

  • 772

I have installed memcache on a Dreamhost VPS (Debian GNU/Linux 5.0.9 (lenny) / memcached 1.4.10 ) for a Drupal site .

If for some reason the server needs rebooting, memcache is not restarted and Drupal spits out warnings about not being able to find memcache.

As mentioned in a previous question, I'm using the following script to start & configure memcache

 sudo /etc/init.d/memcached
  • Is it possible to call that script whenever the server is rebooted, if yes how?
  • In case, the above is not possible or fails, how and where could I tell Drupal to bypass memcache.

//pseudo code

  if( memcache == null )
    bypass memcache

EDIT

@Jon Thanks for the template but it's still above my current scripting level! Since I'm only running a single instance of memcache, here's what I have so far

 #! /bin/bash
 ### BEGIN INIT INFO
 # Provides:          memcached
 # Required-Start:    $syslog
 # Required-Stop:     $syslog
 # Should-Start:        $local_fs
 # Should-Stop:        $local_fs
 # Default-Start:     2 3 4 5
 # Default-Stop:      0 1 6
 # Short-Description:    memcached - Memory caching daemon
 # Description:        memcached - Memory caching daemon
 ### END INIT INFO#!/bin/sh -e

 memcached -u www-data -p 11211 -m 128 -d -l 127.0.0.1

It works fine, except that the script is not called after a server reboot! I need help to make this fit with the template structure. I have no idea about the stop or restart command...

  1. The command is: update-rc.d memcached defaults

    You can always man update-rc.d and get more details, but that should install the init script.

    Sorry, can't answer for drupal.

    If it's on debian, then install memcached with apt-get install memcached php5-memcached. It will automatically populate init.d with the required start/stop script, so first remove your tampered memcached start script from init.d and the runlevels either by deleting it manually or give out update-rc.d memcached remove. Then do the apt-get install... And it will auto start/stop each and every time.
