Hey there phx,

I had the same prob. Turns out SELinux is on & causing the issue.
Either configure SELinux to enable loading passenger module or disable
SELinux. For more info, refer to the following:

http://www.modrails.com/documentation/Users%20guide.html#_the_apache_error_log_says_that_the_spawn_manager_script_does_not_exist_or_that_it_does_not_have_permission_to_execute_it

Cheers!

Hey Zac,

thanks for your help, just found the same solution :)

I disabled the hole SELinux thing (system-config-securitylevel), cause
im on VirtualBox.

Greetings,
phx

Hi,

I have installed passengen on CentOS and with following dependencies

Rails 2.3.2

Passenger Installed correctly after I restarted the apache by adding passenger configuration files paths in httpd.conf file but I get the following error message. Please look into this issue and update me what is the wrong in installation

Hi Asif,

I can try to help.

Did you do a custom compilation & installation of ruby? Can you
provide the output for the following: 'whereis ruby', 'whereis gem'

Thank you

[Asif Shams]

Hi Zac,

Thanks for your reply. I did installation of ruby using following instructions:

wget ftp://ftp.ruby-lang.org:21/pub/ruby/1.8/ruby-1.8.6.tar.gz
tar xzvf ruby-1.8.6.tar.gz && cd ruby-1.8.6
./configure && make && make install
source /etc/profile;ruby -v


rubygems are installed using following instructions:

echo 'export PATH=/usr/local/bin:$PATH' > /etc/profile.d/ruby.sh; source /etc/profile
wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz
tar -xzvf rubygems-1.3.1.tgz
cd rubygems-1.3.1
export GEM_HOME=/usr/local/rubygems/gems; mkdir -p $GEM_HOME
ruby setup.rb all --prefix=/usr/local/rubygems
vi /etc/profile.d/rubygems.sh
contents of rubygems.sh are 
export GEM_HOME=/usr/local/rubygems/gems
export GEM_PATH=/usr/local/rubygems/gems
export RUBYLIB=/usr/local/rubygems/lib
export PATH=/usr/local/rubygems/gems/bin:/usr/local/rubygems/bin:$PATH


Following is the output which you have asked me

whereis ruby
ruby: /usr/lib/ruby /usr/local/bin/ruby /usr/local/lib/ruby

whereis gem
gem:

Feel free to communicate in case of more questions

Hi Asif,

From the 'whereis gem' output, the problem seems to be the system has
no idea where rubygems is installed. Anyway, just to make sure, did
you do a 'chmod +x /etc/profile.d/rubygems.sh' ? If you didn't then
that's the issue.

Cheers,

Zac

Hi Zac,

I have reinstall all things including, ruby, rubygems, passenger and following are the out puts of command you asked me earlier

whereis ruby=  ruby: /usr/bin/ruby /usr/lib/ruby /usr/share/man/man1/ruby.1.gz
whereis rubygems = rubygems: /usr/local/rubygems
whereis gem = gem: /usr/bin/gem

and I am getting following error message in error_log file of apache

I think system is not loading rubygems path correctly again, as gems path is different from rubygems path. Can you please tell me how can I resolve this issue that both path should be the same or there is any other issue in this configuration

OR should I need to make a softlink between /usr/bin/gem and /usr/local/rubygems/bin/ directory so where gem is called it should be loaded from rubygems folder

Thanks in advance for your cooperation in this issue

Asif Shams

Hi Asif,

Sorry for the late reply. It's holidays over here.

Anyway, you didn't need to reinstall anything. Another way to solve
your previous issue is by making a symlink of /usr/bin/gem to point
to /usr/local/rubygems/bin/gem. I just realised starting apache does
not load profile scripts so my previous solution was only good for
normal users.

Your latest problem seems to be a missing gem. Try doing a 'gem
install fastthread'.

Actually the path of rubygems is not important, as long as the system
knows where to find the gem command it will work. Also, I noticed your
passenger version is suddenlly an old version, 2.0.6. Please use the
latest version, 2.1.3.

Regards,
Zac

Hi Zac,

I am getting the same error after I configured a soft link between /usr/bin/gem and  /usr/local/rubygems/bin/gem but I am getting the same error message in error_log file

At this point I would recommend you to completely remove Ruby from
your system and reinstall it from scratch. All your current paths seem
to be totally wrong, and reinstalling everything seems easier.

You likely have multiple versions of Ruby installed, some which you
may not be aware of. You need to remove all of them and install only a
single version.

That depends on how you installed Ruby in the past. If you installed
with Yum then you need to remove it with Yum. If you (also) installed
from source then you need to find out which files were installed to
where, and delete them. If you installed RubyGems to yet another
location then you need to locate those files as well, and delete them.

[isaac....@gmail.com]

Hi Asif,

Sorry for the disappearance. Anyway, like Hongli mentioned, you need
to remove all traces of ruby & rubygem from your OS. If that is too
complicated or you OS is relatively fresh, you can consider doing a
fresh install & start over.

Once you have done that, give an update here. I'll guide you through.
I myself am running a few production servers with Ruby Enterprise
Edition together with Passenger & have no issues. So I'm sure I can
help you through this.

Regards,
Zac

Hi Zac,

I have tried on new installation of CentOS with following commands:

rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/yum-[latest].rpm
yum remove ruby
wget ftp://ftp.ruby-lang.org:21/pub/ruby/1.8/ruby-1.8.6.tar.gz

tar xzvf ruby-1.8.6.tar.gz && cd ruby-1.8.6
./configure && make && make install
source /etc/profile;ruby -v

ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-linux]

echo 'export PATH=/usr/local/bin:$PATH' > /etc/profile.d/ruby.sh; source /etc/profile

wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz

tar -xzvf rubygems-1.3.1.tgz
cd rubygems-1.3.1
export GEM_HOME=/usr/local/rubygems/gems; mkdir -p $GEM_HOME
ruby setup.rb all --prefix=/usr/local/rubygems

vi /etc/profile.d/rubygems.sh  

export GEM_HOME=/usr/local/rubygems/gems
export GEM_PATH=/usr/local/rubygems/gems
export RUBYLIB=/usr/local/rubygems/lib
export PATH=/usr/local/rubygems/gems/bin:/usr/local/rubygems/bin:$PATH

source /etc/profile

Now the gem installations
gem install --version '=2.2.2' actionmailer
gem install --version '=2.2.2' activeresource activesupport
gem install --version '=1.0.1' fastthread
gem install --version '=2.7' mysql -- --with-mysql-config
gem install --version '=2.0.6' passenger
gem install --version '=0.8.3' rake
gem install --version '=2.2.2' rails
gem install --version '=1.2.4' sqlite3-ruby
gem install --version '2.0.6' passenger
passenger-install-apache2-module 

====================
These are the steps followed by our hosting company on Red Hat Linux server and we are using mod_rails successfully on that server
====================

But I am still getting the same error message which is already communicated to you, Can you please
provide me the steps of installation of mod_rails on new CentOS

Following are the output of whereis commands

whereis ruby
ruby: /usr/lib/ruby /usr/local/bin/ruby /usr/local/lib/ruby

whereis rubygems
rubygems: /usr/local/rubygems

whereis gems
gems:

It appears that gems are not loaded into system, Can you send me a installation guide of passenger for CentOS on aasif...@hotmail.com

Asif Shams

Hi Asif,

Ok, I'll need you to do another fresh install of CentOS. After that
you can follow the following steps.

rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/python-iniparse-0.2....

rpm -Uvh http://mirror.centos.org/centos/5/os/i386/CentOS/yum-[latest].rpm
yum remove ruby
wget ftp://ftp.ruby-lang.org:21/pub/ruby/1.8/ruby-1.8.6.tar.gz
tar xzvf ruby-1.8.6.tar.gz && cd ruby-1.8.6

./configure --prefix=/usr && make && make install

wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz
tar -xzvf rubygems-1.3.1.tgz
cd rubygems-1.3.1

ruby setup.rb

The biggest difference is that I do not make a script to load ruby
environment in /etc/profile & ruby is installed in /usr. I also do not
install rubygems to a custom directory. This seems to be the main
issue for you.

Now for the gems installation, please do NOT install custom versions
of the gems you require, unless you have VERY specific reasons, such
as only that version of the gem can work with your application.

So for gems installation, it can be simplified to just the following:

gem install rails
gem install fastthread
gem install mysql -- --with-mysql-config
gem install passenger
gem install sqlite3-ruby
passenger-install-apache2-module

This should work. I myself am using Ruby Enterprise Edition. The one
big benefit of using Ruby Enterprise Edition is that you do not have
to do much for installation. It auto installs ruby, rubygems & most of
the general gems needed. But its all in a self contained folder. So if
your system already have ruby, it won't interfere with it.

Good luck!

Regards,
Zac

Hi Asif,

Quick question, how did you install mysql? Is it already installed?
Actually I just copied that particular line from your steps as I
vaguely remember it to be something similiar. If you installed mysql
using yum, then all you need to do is this --> gem install mysql

If you compiled your own version of mysql, then it will be like this --
> -- --with-mysql-config=location_of_mysql_config

Replace location_of_mysql_config with full path to mysql_config.

If you do not use mysql, then there's no point installing this gem.

Zac

You also need to run 'yum install mysql-devel', for the development headers.

Hi Asif,

In that case just do a 'yum install mysql-devel' as Hongli mentioned
to be safe. Then 'gem install mysql'.

Is anything else failing? Also, please do try to create a new rails
test app, make sure you can start it with webrick, then try configure
passenger to point to that rails test app.

Regards,
Zac

Hi Zaac / All,

I have installed ruby version 1.8.6 on a Red Hat Linux server (Production server). Then I have installed rubygems version 3.1 and 3.5 but I got following error message when I try to execute gem install rails command

Following are the steps I performed on my servers

yum remove ruby

Then I removed each ruby file on system after getting response by command
whereis ruby

wget ftp://ftp.ruby-lang.org:21/pub/ruby/1.8/ruby-1.8.6.tar.gz

tar xzvf ruby-1.8.6.tar.gz && cd ruby-1.8.6
./configure --prefix=/usr && make && make install

wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz

tar -xzvf rubygems-1.3.1.tgz
cd rubygems-1.3.1

ruby setup.rb                   ##### All went correctly #############
gem install rails                 ##### Here the error comes #############

==========================================

Previously Mongrel was configured on this server I have uninstall all gems from this server by commands "gem uninstall gemname". Also I have removed the profile files for ruby and rubygems and rubygems folder. I have also removed the rubygems folder from /usr/local/rubygems (where rubygems were previously installed)
 
According to my understanding, this issue is due to environment paths, the system is still picking the old paths for zlib library, as this file exist at error location

Or is there any other solution to solve this problem. Can you please guide me

You can also send me the steps for installation of mod_rails on Linux. Thanks in advance

Regards,
Asif Shams

This error means that the zlib Ruby extension isn't installed. You
need to make sure that it's installed.
