Ubuntu - Apache - Rails - Passenger - Spawning error - ruby-on-rails-3

I've got the error where passenger complains that:
*** Passenger ERROR (ext/common/ApplicationPool/../SpawnManager.h:220):
Could not start the spawn server: /usr/local/rvm/gems/ruby-1.9.3-head/ruby: No such file or directory (2)
[ pid=8970 thr=139698295748416 file=ext/apache2/Hooks.cpp:865 time=2012-11-07 17:17:32.422 ]: Unexpected error in mod_passenger: Cannot spawn application '/www/lensfinder.se/ruby/lensfinder': Could not read from the spawn server: Connection reset by peer (104)
Backtrace:
in 'virtual Passenger::SessionPtr Passenger::ApplicationPool::Client::get(const Passenger::PoolOptions&)' (Client.h:750)
in 'Passenger::SessionPtr Hooks::getSession(const Passenger::PoolOptions&)' (Hooks.cpp:297)
in 'int Hooks::handleRequest(request_rec*)' (Hooks.cpp:566)
From what I can read is that it cant access /www/lensfinder.se/ruby/lensfinder though it exist.
And I found this FAQ on Phusion Passengers site
The problem is that, when I try to use that command,
passenger-config --root
I get this:
-bash: /usr/bin/passenger-config: ruby: bad interpreter: No such file or directory

Ok my guess is that you point Passenger to the wrong directory. You should point it to the public directory of your Rails app.
Here's a minimalist configuration for your project that goes in /etc/apache2/sites-available/lensfinder.se:
<VirtualHost 10.0.0.37:80>
ServerAdmin hostmaster#compartment.se
ServerName lensfinder.se
ServerAlias *.lensfinder.se
DocumentRoot /www/lensfinder.se/ruby/lensfinder/public
RailsEnv production
<Directory "/www/lensfinder.se/ruby/lensfinder/public">
Options FollowSymLinks
AllowOverride All
Options -MultiViews
</Directory>
</VirtualHost>
Then edit /etc/apache2/apache2.conf and at the end of the file, add :
LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12/ext/apache2/mod_passenger.so
PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-head/gems/passenger-3.0.12
PassengerRuby /usr/local/rvm/wrappers/ruby-1.9.3-head/ruby
then simlink your virtualhost config to enable it:
ln -s /etc/apache2/sites-available/lensfinder.se /etc/apache2/sites-enabled/lensfinder.se
And of course restart apache2

In addition to the previous answer, In my case even after editing configuration files I still had issues loading up Apache as the module was still configured to load the previous (global) .so file.
I found there were source files and scripts in the /usr/local/rvm/gems/[YOUR-RUBY-VER]/gems/passenger-[YOUR-PASSENGER-VER]/ext/apache2/ directory, but no binaries. There were however scripts provided to build those. Simply run sudo /usr/local/rvm/gems/ruby-[YOUR-RUBY-VER]/gems/passenger-[YOUR-PASSENGER-VER]/bin/passenger-install-apache2-module.

.htaccess not working with SSL config

I followed this guide to get a free SSL certificate from StartSSL: https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-with-a-free-signed-ssl-certificate-on-a-vps
I followed it step by step but I don't actually understand it fully as I'm a newbie.
I have .htaccess which stopped working after I put the below code into my 000-default.conf file:
<VirtualHost *:443>
SSLEngine on
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM
SSLCertificateFile /etc/apache2/ssl/ssl.crt
SSLCertificateKeyFile /etc/apache2/ssl/private.key

</VirtualHost>
This is what's in my .htaccess file:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^([a-zA-Z0-9\-]+)$ $1.php
ErrorDocument 404 /404error
</IfModule>
^ It's basically to be able to access a page like this domain/page rather than like this: domain/page.php
So as soon as I add the above code from the 000-default.conf file, the rewrite rule works fine. If I add it in, however, I can no longer access files without the .php at the end. My 404 redirect is also not working.
What is it that's causing the problem?

Virtual Host not recognized

currently I'm trying to set a VHost but somehow it is not working.
I've disabled the vhosts in my machine and I have just one. The page does not load. If I access localhost I get 403 Forbidden
My vhost:
<VirtualHost *:80>
ServerAdmin admin#myvhost.test
ServerName myvhost.test
DocumentRoot /folder/to/app
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /folder/to/app>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
and if I run
apache2ctl -S
I get
VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:80 is a NameVirtualHost
default server myvhost.test (/etc/apache2/sites-enabled/myvhost:1)
port 80 namevhost myvhost.test (/etc/apache2/sites-enabled/myvhost:1)
Syntax OK
What am I missing here?
Thank you

Apache 2.4.7 403 Forbidden Error

I'm trying to install the overpass api as a web server with apache (http://wiki.openstreetmap.org/wiki/Overpass_API/install)
Here is my 000-default.conf
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ExtFilterDefine gzip mode=output cmd=/bin/gzip
DocumentRoot /root/osm-3s_v0.7.4/html
# This directive indicates that whenever someone types http://www.mydomain.com/api/
# Apache2 should refer to what is in the local directory [YOUR_EXEC_DIR]/cgi-bin/
ScriptAlias /api/ /srv/osm3s/cgi-bin/
# This specifies some directives specific to the directory: [YOUR_EXEC_DIR]/cgi-bin/
<Directory "/srv/osm3s/cgi-bin/">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
#SetOutputFilter gzip
#Header set Content-Encoding gzip
</Directory>
ErrorLog /var/log/apache2/error.log
# Possible values include: debug, info, notice, warn, error, crit, alert, emerg
LogLevel warn
CustomLog /var/log/apache2/access.log combined
However when I try to run the command:
http://175.33.148.57/api/interpreter?data=%3Cprint%20mode=%22body%22/%3E
I get the 403 Forbidden error.
I have already done
chmod 777 /srv/osm3s/cgi-bin/
But nothing seems to work.
Please help, Ive been stuck on this for 3 days now! Thanks in advance.
Replace:
Allow from all
by
Require all granted
<Directory /www/mysite>
Allow from All
</Directory>
<Directory /www/mysite>
Require all granted
</Directory>
Here is how I solved this problem for anyone who might have a similar one:
It seemed the problem came from where I installed the overpass installation ($EXEC_DIR).
So I had to change the install directories to:
$EXEC_DIR /var/www/osm/
$DB_DIR /var/www/osm/db/
$PLANET_FILE /var/www/osm/planet.osm.bz2
$REPLICATE_DIR /var/www/osm/rep/
Giving the resulting default.conf:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ExtFilterDefine gzip mode=output cmd=/bin/gzip
DocumentRoot /root/osm-3s_v0.7.4/html
# This directive indicates that whenever someone types http://www.example.com/api/
# Apache2 should refer to what is in the local directory [YOUR_EXEC_DIR]/cgi-bin/
ScriptAlias /api/ /var/www/osm/cgi-bin/
# This specifies some directives specific to the directory: [YOUR_EXEC_DIR]/cgi-bin/
<Directory "/var/www/osm/cgi-bin/">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
#SetOutputFilter gzip
#Header set Content-Encoding gzip
</Directory>
ErrorLog /var/log/apache2/error.log
# Possible values include: debug, info, notice, warn, error, crit, alert, emerg
LogLevel warn
CustomLog /var/log/apache2/access.log combined
</VirtualHost>
I tried and tried but couldn't get it working with the old dir. Good luck!
try this as it is. don't add Order allow,deny or others
AddHandler cgi-script .cgi .py
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride None

Properly configure .htaccess

On localhost I have a file filename.html and an .htaccess in the same folder.
I need to figure out why my .htaccess is not working:
redirect 301 /filename.html http://www.google.com
I am on linux, I have configured the server:
sudo nano /etc/apache2/sites-available/default
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride All
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride All
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,

</VirtualHost>
sudo service apache2 restart
I found:
RewriteEngine On

RewriteRule ^test\.html http://www.google.com/? [R=301,L]
my RewriteEngine is working.

Configuring apache with fastcgi in Haskell

I am trying to run my Haskel fastcgi program with apache (Server version: Apache/2.2.15 (Cent OS 6)),
Following are the changes done in httpd.conf
<IfModule fastcgi_module>
AddHandle fastcgi-script .fcgi
</IfModule>
LoadModule fastcgi_module modules/mod_fastcgi.so
<VirtualHost *:80>
ServerAdmin webmaster#<hostname>

Order allow,deny
Allow from all
</Directory>
<Directory "/var/www/cgi-bin">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
I followed all the instructions as specified here
When I visit the link curl --include http:// hostname/cgi-bin/test.fcgi
I get error in apache server log as
[error] Premature end of script headers: test.fcgi
How can I debug this issue ?
