gaurish/apache2.conf

## apache2.conf
#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
#  1. Directives that control the operation of the Apache server process as a
#     whole (the 'global environment').
#  2. Directives that define the parameters of the 'main' or 'default' server,
#     which responds to requests that aren't handled by a virtual host.
#     These directives also provide default values for the settings
#     of all virtual hosts.
#  3. Settings for virtual hosts, which allow Web requests to be sent to
#     different IP addresses or hostnames and have them handled by the
#     same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "/etc/apache2"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
#<IfModule !mpm_winnt.c>
#<IfModule !mpm_netware.c>
LockFile /var/lock/apache2/accept.lock
#</IfModule>
#</IfModule>

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 100

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5

#
# AccessFileName: The name of the file to look for in each directory

# directive.
#

AccessFileName .htaccess

#

#
# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value.  If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/plain


#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here.  If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog /var/log/apache2/error.log

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel warn

# Include module configuration:
Include /etc/apache2/mods-enabled/*.load
Include /etc/apache2/mods-enabled/*.conf

# Include all the user configurations:
Include /etc/apache2/httpd.conf

# Include ports listing
Include /etc/apache2/ports.conf

#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
# If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i
#
LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %O" common
LogFormat "%{Referer}i -> %U" referer

## deploy.rb
require 'bundler/capistrano'


# you can configure your Rails
# app to use this deployment recipe by doing the following:
#
# 1. Add `gem 'capistrano'` to your Gemfile.
# 2. Run `bundle install --binstubs --path=vendor/bundles`.
# 3. Run `bin/capify .` in your app's root directory.
# 4. Replace your new config/deploy.rb with this file's contents.
# 5. Configure the two parameters in the Configuration section below.
# 6. Run `git commit -a -m "Configured capistrano deployments."`.
# 7. Run `git push origin master`.
# 8. Run `bin/cap deploy:setup`.
# 9. Run `bin/cap deploy:migrations` or `bin/cap deploy`.
#
# Note: You may also need to add your local system's public key to
# your GitHub repository's Admin / Deploy Keys area.
#
# Note: When deploying, you'll be asked to enter your server's root
# password. To configure password-less deployments, see below.

# PassengerLogLevel 0

# PassengerUseGlobalQueue

PassengerUseGlobalQueue on

## PassengerUserSwitching
#
# Enable User Switching Support. This option starts your application
# as the owner of the file config/environment.rb. The owner of
# environment.rb must have read access to the Rails application's
# folder, and read/write access to the Rails application's logs folder.
# This feature is only available if Apache is started by root.
#
# Options: <on|off>

# PassengerUserSwitching on


## PassengerDefaultUser
#
# Specify the user Passenger must run as. This option allows you
# to specify which user your application will run as if user
# switching fails or is disabled.

# PassengerDefaultUser deploy


## PassengerMaxPoolSize
#
# Set the maximum number of application instances that can be
# simultaneously active. A larger number results in higher
# memory usage, but improved ability to handle concurrent HTTP clients.
# The optimal value depends on your system's hardware and the server's
# average load. You should experiment with different values. Generally
# speaking, the value should be at least equal to the number of CPUs
# (or CPU cores) that you have. If your system has 2 GB of RAM, then
# we recommend a value of 30. If your system is a Virtual Private
# Server (VPS) and has about 256 MB RAM, and is also running other
# services such as MySQL, then we recommend a value of 2.

PassengerMaxPoolSize 8


## PassengerMaxInstancesPerApp
#
# Set the maximum number of application instances that may
# be simultaneously active for a single application. This helps to
# make sure that a single application will not occupy all available
# slots in the application pool. This value must be less than
# PassengerMaxPoolSize. A value of 0 means that there is no limit
# placed on the number of instances a single application may use,
# i.e. only the global limit of PassengerMaxPoolSize will be enforced.

# PassengerMaxInstancesPerApp 0


## PassengerPoolIdleTime
#
# Set the maximum number of seconds that your application instance
# may be idle. That is, if an application instance hasn't done anything
# after the given number of seconds, then it will be shutdown in order
# to conserve memory. Decreasing this value means that applications
# will have to be spawned more often. Since spawning is a relatively
# slow operation, some visitors may notice a small delay when they
# visit your website. However, it will also free up resources used by
# applications more quickly. The optimal value depends on the average
# time that a visitor spends on a single Rails/Rack web page. We
# recommend a value of 2 * x, where x is the average number of seconds
# that a visitor spends on a single web page. But your mileage may vary.

# PassengerPoolIdleTime 300


##
## The following options are Rails specific options. They may occur
## here in the global configuration or in your VirtualHost entry.
##


## RailsAutoDetect
#
# Set whether Phusion Passenger should automatically detect whether
# a virtual host's document root is a Ruby on Rails application.
# The default is on.
# Options: <on|off>

# RailsAutoDetect on


## RailsBaseURI
#
# Specify that the given URI is a Rails application. It is allowed to
# specify this option multiple times. Do this to deploy multiple
# Rails applications in different sub-URIs under the same virtual host.

# RailsBaseURI <uri>


## RailsAllowModRewrite
#
# Passenger will not override mod_rewrite rules if this option
# is enabled.
# Options: <on|off>

# RailsAllowModRewrite off


## RailsEnv
#
# Use this option to specify the default RAILS_ENV value. The default
# setting is production.

# RailsEnv production


## RailsSpawnMethod
#
# Internally, Phusion Passenger spawns multiple Ruby on Rails processes
# in order to handle requests. But there are multiple ways with which
# processes can be spawned, each having its own set of pros and cons.
# Supported spawn methods are:
#  smart
#    When this spawn method is used, Phusion Passenger will attempt
#    to cache Ruby on Rails framework code and application code for
#    a limited period of time.
#
#  conservative
#    This spawning method is similar to the one used in Mongrel Cluster.
#    It does not perform any code caching at all.

# RailsSpawnMethod smart


## PassengerMaxRequests
#
# Restarts each Passenger process after n number of requests processed.

# PassengerMaxRequests 100

	#
	# Based upon the NCSA server configuration files originally by Rob McCool.
	#
	# This is the main Apache server configuration file. It contains the
	# configuration directives that give the server its instructions.
	# See http://httpd.apache.org/docs/2.2/ for detailed information about
	# the directives.
	#
	# Do NOT simply read the instructions in here without understanding
	# what they do. They're here only as hints or reminders. If you are unsure
	# consult the online docs. You have been warned.
	#
	# The configuration directives are grouped into three basic sections:
	# 1. Directives that control the operation of the Apache server process as a
	# whole (the 'global environment').
	# 2. Directives that define the parameters of the 'main' or 'default' server,
	# which responds to requests that aren't handled by a virtual host.
	# These directives also provide default values for the settings
	# of all virtual hosts.
	# 3. Settings for virtual hosts, which allow Web requests to be sent to
	# different IP addresses or hostnames and have them handled by the
	# same Apache server process.
	#
	# Configuration and logfile names: If the filenames you specify for many
	# of the server's control files begin with "/" (or "drive:/" for Win32), the
	# server will use that explicit path. If the filenames do not begin
	# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
	# with ServerRoot set to "" will be interpreted by the
	# server as "//var/log/apache2/foo.log".
	#

	### Section 1: Global Environment
	#
	# The directives in this section affect the overall operation of Apache,
	# such as the number of concurrent requests it can handle or where it
	# can find its configuration files.
	#

	#
	# ServerRoot: The top of the directory tree under which the server's
	# configuration, error, and log files are kept.
	#
	# NOTE! If you intend to place this on an NFS (or otherwise network)
	# mounted filesystem then please read the LockFile documentation (available
	# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
	# you will save yourself a lot of trouble.
	#
	# Do NOT add a slash at the end of the directory path.
	#
	ServerRoot "/etc/apache2"

	#
	# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
	#

	#<IfModule !mpm_netware.c>
	LockFile /var/lock/apache2/accept.lock
	#</IfModule>
	#</IfModule>

	#
	# PidFile: The file in which the server should record its process
	# identification number when it starts.
	# This needs to be set in /etc/apache2/envvars
	#
	PidFile ${APACHE_PID_FILE}

	#
	# Timeout: The number of seconds before receives and sends time out.
	#
	Timeout 100

	#
	# KeepAlive: Whether or not to allow persistent connections (more than
	# one request per connection). Set to "Off" to deactivate.
	#
	KeepAlive On

	#
	# MaxKeepAliveRequests: The maximum number of requests to allow
	# during a persistent connection. Set to 0 to allow an unlimited amount.
	# We recommend you leave this number high, for maximum performance.
	#
	MaxKeepAliveRequests 100

	#

	## passenger.conf -- Passenger configuration file
	##
	##


	# This is the Passenger configuration file. It contains the
	# configuration directives for Passenger. See
	# <URL:http://www.modrails.com/documentation/Users guide.html>
	# for detailed information about the directives.

	# Passenger Settings for Ruby Enterprise
	LoadModule passenger_module /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.17/ext/apache2/mod_passenger.so
	PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.17
	PassengerRuby /usr/local/bin/ruby

	## PassengerLogLevel
	#
	# Specify how much information Phusion Passenger should write to the
	# Apache error log file. A higher log level value means that more
	# information will be logged.
	#
	# 0: Show only errors and warnings. This is the default setting.
	# 1: Show the most important debugging information. This might be useful
	# for system administrators who are trying to figure out the cause
	# of a problem.
	# 2: Show more debugging information. This is typically
	# only useful for developers.
	# 3: Show even more debugging information.

	# PassengerLogLevel 0

	# PassengerUseGlobalQueue

	PassengerUseGlobalQueue on

	## PassengerUserSwitching
	#
	# Enable User Switching Support. This option starts your application
	# as the owner of the file config/environment.rb. The owner of
	# environment.rb must have read access to the Rails application's
	# folder, and read/write access to the Rails application's logs folder.
	# This feature is only available if Apache is started by root.
	#
	# Options: <on\|off>

	# PassengerUserSwitching on



	## PassengerDefaultUser
	#
	# Specify the user Passenger must run as. This option allows you
	# to specify which user your application will run as if user
	# switching fails or is disabled.

	# PassengerDefaultUser deploy


	## PassengerMaxPoolSize
	#
	# Set the maximum number of application instances that can be
	# simultaneously active. A larger number results in higher
	# memory usage, but improved ability to handle concurrent HTTP clients.
	# The optimal value depends on your system's hardware and the server's
	# average load. You should experiment with different values. Generally
	# speaking, the value should be at least equal to the number of CPUs
	# (or CPU cores) that you have. If your system has 2 GB of RAM, then
	# we recommend a value of 30. If your system is a Virtual Private
	# Server (VPS) and has about 256 MB RAM, and is also running other
	# services such as MySQL, then we recommend a value of 2.

	PassengerMaxPoolSize 8


	## PassengerMaxInstancesPerApp
	#
	# Set the maximum number of application instances that may
	# be simultaneously active for a single application. This helps to
	# make sure that a single application will not occupy all available
	# slots in the application pool. This value must be less than
	# PassengerMaxPoolSize. A value of 0 means that there is no limit
	# placed on the number of instances a single application may use,
	# i.e. only the global limit of PassengerMaxPoolSize will be enforced.

	# PassengerMaxInstancesPerApp 0



	## PassengerPoolIdleTime
	#
	# Set the maximum number of seconds that your application instance
	# may be idle. That is, if an application instance hasn't done anything
	# after the given number of seconds, then it will be shutdown in order
	# to conserve memory. Decreasing this value means that applications
	# will have to be spawned more often. Since spawning is a relatively
	# slow operation, some visitors may notice a small delay when they
	# visit your website. However, it will also free up resources used by
	# applications more quickly. The optimal value depends on the average
	# time that a visitor spends on a single Rails/Rack web page. We
	# recommend a value of 2 * x, where x is the average number of seconds
	# that a visitor spends on a single web page. But your mileage may vary.

	# PassengerPoolIdleTime 300


	##
	## The following options are Rails specific options. They may occur
	## here in the global configuration or in your VirtualHost entry.
	##


	## RailsAutoDetect
	#
	# Set whether Phusion Passenger should automatically detect whether
	# a virtual host's document root is a Ruby on Rails application.
	# The default is on.
	# Options: <on\|off>

	# RailsAutoDetect on


	## RailsBaseURI
	#
	# Specify that the given URI is a Rails application. It is allowed to
	# specify this option multiple times. Do this to deploy multiple
	# Rails applications in different sub-URIs under the same virtual host.

	# RailsBaseURI <uri>


	## RailsAllowModRewrite
	#
	# Passenger will not override mod_rewrite rules if this option
	# is enabled.
	# Options: <on\|off>

	# RailsAllowModRewrite off



	## RailsEnv
	#
	# Use this option to specify the default RAILS_ENV value. The default
	# setting is production.

	# RailsEnv production



	## RailsSpawnMethod
	#
	# Internally, Phusion Passenger spawns multiple Ruby on Rails processes
	# in order to handle requests. But there are multiple ways with which
	# processes can be spawned, each having its own set of pros and cons.
	# Supported spawn methods are:
	# smart
	# When this spawn method is used, Phusion Passenger will attempt
	# to cache Ruby on Rails framework code and application code for
	# a limited period of time.
	#
	# conservative
	# This spawning method is similar to the one used in Mongrel Cluster.
	# It does not perform any code caching at all.

	# RailsSpawnMethod smart



	## PassengerMaxRequests
	#
	# Restarts each Passenger process after n number of requests processed.

	# PassengerMaxRequests 100
