configure apache passenger problem

[Hai Tao]

I am configuring apache passenger by following the doc
http://projects.reductivelabs.com/projects/puppet/wiki/Using_Passenger

I am getting following erros when start httpd:

]# /etc/init.d/httpd start
Starting httpd: httpd: Syntax error on line 221 of
/etc/httpd/conf/httpd.conf: Syntax error on line 5 of
/etc/httpd/conf.d/10_passenger.conf: Cannot load

into server: /usr/lib/ruby/gems/1.8/gems/passenger-3.0.12/ext/apache2/mod_passenger.c:

the /usr/lib/ruby/gems/1.8/gems/passenger-3.0.12/ext/apache2/mod_passenger.c
is the only thing I found in my system, I cannot find a
mod_passenger.so file.

here is my config, please help:

When I was just setting up passenger, I had to alter that line referencing mod_passenger.so to our apache modules directory.

# LoadModule passenger_module 

/usr/lib/ruby/gems/1.8/gems/passenger-2.2.11/ext/apache2/mod_passenger.so 

This needed to be changed to /etc/httpd/modules/mod_passenger.so since that is where apache has the module for passenger. I think you just need to track down where that module is and point the configuration to the right place.

Sound like you only have the passenger gem installed, it needs to install the apache module.  Here is a snippet from a Centos puppet build.

####    init.pp    ####
#
# modules/passenger/manifests/init.pp
class passenger {

  package { 'rack':
    ensure   => '1.1.0',
    provider => 'gem',
    require  => Class['rubygems'],
    before   => Package['passenger'],
  }

  package { 'passenger':
    ensure   => installed,
    provider => 'gem',
    require  => Package['rack'],
    before   => File['/opt/passenger'],
  }

  ####
  # auto install passenger apache2 module and create links
  file { '/opt/passenger':
    ensure => 'directory',
    owner  => 'root',
    group  => 'root',
    mode   => '0755',
    before => File['/opt/passenger/auto_passenger_install.sh'],
  }

  file { '/opt/passenger/auto_passenger_install.sh':
    ensure => 'present',
    owner  => 'root',
    group  => 'root',
    mode   => '0755',
      source => 'puppet:///modules/passenger/auto_passenger_install.sh',
    before => Exec['auto_passenger_install'],
  }

  exec { 'auto_passenger_install':
    command => '/opt/passenger/auto_passenger_install.sh',
    timeout => '900',
    creates => '/etc/passenger',
  }
}

The install script.  This installs the mod_passenger.so and links the directory to /etc/passenger (which means easy to upgrade version, the link is just swapped - apache still needs to restart as it reads the hardlink when started.)

#!/bin/bash
####   auto_passenger_install.sh   ####
#
# modules/passenger/files/auto_passenger_install.sh
#########
# Script variables
SCRIPT=$(readlink -f $0)
SCRIPTNAME=$(basename "$SCRIPT")
SCRIPTPATH=$(dirname $SCRIPT)
SERVER=`hostname | cut -d'.' -f1-1`
TIMESTAMP=$(date +%s)
RUNDATE=`date -d @$TIMESTAMP +%Y%m%d%H%M%S`
LOG_PATH=/var/log/scripts/$SCRIPTNAME
if [ ! -d $LOG_PATH ]; then
  mkdir -p $LOG_PATH
fi
LOGFILE=$LOG_PATH/$RUNDATE.$SCRIPTNAME.log

RUBYGEMS_VER_DIR=$(basename `facter rubysitedir`)
PASSENGER_VERSION=`gem list --local | grep passenger | sed -e 's/passenger (//g;s/)//g'`
cd /usr/lib/ruby/gems/$RUBYGEMS_VER_DIR/gems/passenger-$PASSENGER_VERSION
