1) Install fcgi and mod_fastcgi RPMs for el6
# rpm -ivh fcgi-2.4.0-10.el6.x86_64.rpm
# rpm -ivh mod_fastcgi-2.4.6-2.el6.rf.x86_64.rpm

2) install ceph-radosgw
# yum install ceph-radosgw

3) Copy /etc/ceph/ceph.conf from 10.42.3.10 and add the radosgw informations
[client.radosgw.gateway]
        host = rados-gw
        keyring = /etc/ceph/keyring.radosgw.gateway
        rgw socket path = /tmp/radosgw.sock
        log file = /var/log/ceph/radosgw.log
        rgw print continue = false

Note: For consistency, it is preferable to update all ceph.conf with this information since an update pushed from another server will overwrite it.

4) Create radosgw dir
# mkdir -p /var/lib/ceph/radosgw/ceph-radosgw.gateway

5) Change httpd ServerName in /etc/httpd/conf/httpd.conf
ServerName rados-gw

6) Create apache httpd vhost in /etc/httpd/conf.d/rgw.conf:
FastCgiExternalServer /var/www/s3gw.fcgi -socket /tmp/radosgw.sock
<VirtualHost *:80>
        ServerName rados-gw
        ServerAdmin root@localhost
        DocumentRoot /var/www
  RewriteEngine On
	RewriteRule ^/([a-zA-Z0-9-_.]*)([/]?.*) /s3gw.fcgi?page=$1&params=$2&%{QUERY_STRING} [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
	<IfModule mod_fastcgi.c>
	  <Directory /var/www>
		Options +ExecCGI
		AllowOverride All
		SetHandler fastcgi-script
		Order allow,deny
		Allow from all
		AuthBasicAuthoritative Off
    	 </Directory>
       </IfModule>
        AllowEncodedSlashes On
        ErrorLog /var/log/httpd/error.log
        CustomLog /var/log/httpd/access.log combined
        ServerSignature Off
</VirtualHost>

7) Comment the following line in /etc/httpd/conf.d/fastcgi.conf:
	#FastCgiWrapper On

8) Create /var/www/s3gw.fcgi with the following content:
#!/bin/sh 
exec /usr/bin/radosgw -c /etc/ceph/ceph.conf -n client.radosgw.gateway

9) Make s3gw.fcgi executable:
# chmod +x /var/www/s3gw.fcgi

9) Create client.radosgw.gateway user key:
# ceph-authtool -C -n client.radosgw.gateway --gen-key /etc/ceph/keyring.radosgw.gateway
# ceph-authtool -n client.radosgw.gateway --cap mon 'allow r' --cap osd 'allow rwx' /etc/ceph/keyring.radosgw.gateway
# ceph auth add client.radosgw.gateway --in-file=keyring.radosgw.gateway

10) Update /etc/init.d/ceph-radosgw to work on RH (see file)

11) Create .rgw.buckets and add it to radosgw from setup42-3
# rados mkpool .rgw.buckets
# radosgw-admin pool add --pool .rgw.buckets

12) Make apache and radosgw start on boot
# chkconfig httpd on
# chkconfig ceph-radosgw on

13) Start the services
# /etc/init.d/httpd start
# /etc/init.d/ceph-radosgw start
