.SH DESCRIPTION
|
|
.sp
|
|
\fBradosgw\fP is an HTTP REST gateway for the RADOS object store, a part
|
|
of the Ceph distributed storage system. It is implemented as a FastCGI
|
|
module using libfcgi, and can be used in conjunction with any FastCGI
|
|
capable web server.
|
|
.SH OPTIONS
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-c ceph.conf, \-\-conf=ceph.conf
|
|
Use \fIceph.conf\fP configuration file instead of the default
|
|
\fB/etc/ceph/ceph.conf\fP to determine monitor addresses during startup.
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-m monaddress[:port]
|
|
Connect to specified monitor (instead of looking through
|
|
\fBceph.conf\fP).
|
|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP
|
|
.B \-\-rgw\-socket\-path=path
|

.SH CONFIGURATION
|
|
.sp
|
|
Currently it's the easiest to use the RADOS Gateway with Apache and mod_fastcgi
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
FastCgiExternalServer /var/www/s3gw.fcgi -socket /tmp/radosgw.sock
|
|
|
|
<VirtualHost *:80>
|
|

|
|
ServerAlias rgw
|

|
|

|
|
|
|
RewriteEngine On
|
|

|

ServerSignature Off
|
|
</VirtualHost>
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
And the corresponding radosgw script (/var/www/s3gw.fgci):
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
#!/bin/sh
|
|
exec /usr/bin/radosgw -c /etc/ceph/ceph.conf -n client.radosgw.gateway
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
The radosgw daemon is a standalone process which needs a configuration section in the ceph.conf
|
|
The section name should start with 'client.radosgw.' as specified in /etc/init.d/radosgw
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
[client.radosgw.gateway]
|
|
host = gateway
|
|
keyring = /etc/ceph/keyring.radosgw.gateway
|
|
rgw socket path = /tmp/radosgw.sock
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
You will also have to generate a key for the radosgw to use for authentication with the cluster
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
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' --cap mds 'allow' /etc/ceph/keyring.radosgw.gateway
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
And add the key to the auth entries
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
ceph auth add client.radosgw.gateway --in-file=keyring.radosgw.gateway
|
|
.ft P
|
|
.fi
|
|
.sp
|
|
Now you can start Apache and the radosgw daemon
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
/etc/init.d/apache2 start
|
|
/etc/init.d/radosgw start
|
|
.ft P
|
|
.fi
|
|
