+=============================
+ Installing Apache & FastCGI
+=============================
+
+The :term:`Ceph Object Gateway` runs on Apache and FastCGI. The Ceph Object
+Gateway also supports 100-continue. However, you must install Ceph builds
+of Apache and FastCGI for 100-continue support.
+
+
+Install w/out 100-Continue
+==========================
+
+You may use standard Apache and FastCGI packages for your Ceph Object
+Gateways. However, they will not provide 100-continue support.
+
+Debian Packages
+---------------
+
+To install Apache and FastCGI Debian packages, execute the following:: 
+
+	sudo apt-get install apache2 libapache2-mod-fastcgi
+
+
+RPM Packages
+------------
+
+To install Apache and FastCGI RPMs, execute the following:: 
+
+	rpm -ivh fcgi-2.4.0-10.el6.x86_64.rpm 
+ 	rpm -ivh mod_fastcgi-2.4.6-2.el6.rf.x86_64.rpm
+
+   Or:: 
+   
+   sudo yum install httpd mod_fastcgi
+
+
+Install w/ 100-Continue
+=======================
+	
+The Ceph community provides a slightly optimized version of the  ``apache2``
+and ``fastcgi`` packages. The material difference is that  the Ceph packages are
+optimized for the ``100-continue`` HTTP response,  where the server determines
+if it will accept the request by first  evaluating the request header. See `RFC
+2616, Section 8`_ for details  on ``100-continue``. You can find the most recent
+builds of Apache and FastCGI packages modified for Ceph at `gitbuilder.ceph.com`_.
+
+
+Debian Packages
+---------------
+
+#. Add a ``ceph-apache.list`` file to your APT sources. :: 
+
+	echo deb http://gitbuilder.ceph.com/apache2-deb-$(lsb_release -sc)-x86_64-basic/ref/master $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph-apache.list
+
+#. Add a ``ceph-fastcgi.list`` file to your APT sources. :: 
+
+	echo deb http://gitbuilder.ceph.com/libapache-mod-fastcgi-deb-$(lsb_release -sc)-x86_64-basic/ref/master $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph-fastcgi.list
+
+#. Update your repository and install Apache and FastCGI:: 
+
+	sudo apt-get update && sudo apt-get install apache2 libapache2-mod-fastcgi
+
+
+RPM Packages
+------------
+
+To install Apache with 100-continue, execute the following steps:
+
+#. Ensure you have ``yum-plugin-priorities`` installed and enabled. See 
+   ``Installing YUM Priorities`_ for details.
+
+#. Add a ``ceph-apache.repo`` file to ``/etc/yum.repos.d``. Replace 
+   ``{distro}`` with the name of your distribution (e.g., ``centos6``, 
+   ``rhel6``, etc.) ::
+
+	[apache2-ceph-noarch]
+	name=Apache noarch packages for Ceph
+	baseurl=http://gitbuilder.ceph.com/apache2-rpm-{distro}-x86_64-basic/ref/master

+   ``rhel6``, etc.) ::
+

+
+
+#. Update your repo and install Apache and FastCGI. :: 
+
+	sudo yum update && sudo yum install httpd mod_fastcgi
+
+
+Modify the Configuration
+========================
+
+To complete the installation, ensure that you have the rewrite module
+enabled and FastCGI enabled. The steps differ slightly based upon the 
+type of package installation. 
+
+Debian-based Packages
+---------------------
+
+#. Open the ``apache2.conf`` file. :: 
+
+	sudo vim /etc/apache2/apache2.conf
+
+
+#. Add a line for the ``ServerName`` in the Apache configuration file. 
+   Provide the fully qualified domain name of the server machine 
+   (e.g., ``hostname -f``). ::
+
+	ServerName {fqdn}
+
+#. Enable the URL rewrite modules for Apache and FastCGI. ::
+
+	sudo a2enmod rewrite
+	sudo a2enmod fastcgi
+
+
+#. Restart Apache so that the foregoing changes take effect. ::
+
+	sudo service apache2 restart
+
+
+RPM-based Packages
+------------------
+
+
+#. Open the ``httpd.conf`` file. :: 
+
+	sudo vim /etc/httpd/conf/httpd.conf
+
+#. Uncomment ``#ServerName`` and add the name of your server. 
+   Provide the fully qualified domain name of the server machine 
+   (e.g., ``hostname -f``).:: 
+
+	ServerName {fgdn}
+
+#. Ensure that the Rewrite module is enabled. :: 
+
+	#if not present, add:
+	LoadModule rewrite_module modules/mod_rewrite.so	
+
+#. Save the ``httpd.conf`` file.
+
+#. Ensure that the FastCGI module is enabled. The installer should
+   include an ``/etc/httpd/conf.d/fastcgi.conf`` file that loads the
+   FastCGI module. :: 
+
+	#if not present, add:
+	LoadModule fastcgi_module modules/mod_fastcgi.so
+
+#. Restart Apache so that the foregoing changes take effect.. :: 
+
+	etc/init.d/httpd restart
+
