            <title>[SERVER-7970] Setting up a cluster on Raspberry Pi</title>
                <link>https://jira.mongodb.org/browse/SERVER-7970</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hi, please see mongopi.wordpress.com for background and progress to date.&lt;/p&gt;

&lt;p&gt;I am trying to build a scale able, ultra low-cost  BI solution (eg load up some data via a recurring ETL process (Pentaho), create some data structures for analysis (aggregation) and produce some nice reports!). This is my MSC project a the University of Dundee - my tutor is doing something similar with Cassandra.&lt;/p&gt;

&lt;p&gt;I have an array of 5 Raspberry Pis (512MB), 32GB SD cards. I have successfully installed RickP&apos;s fork of MongoDB (2.2.1) via GitHub.&lt;/p&gt;

&lt;p&gt;Additionally, I have a Dell Dimension 5100 (4GB RAM) which I intended to use as the &apos;master/control&apos; machine. This is running the latest version of MongoDB for Linux.&lt;/p&gt;


&lt;p&gt;I am now struggling with 2 things&lt;br/&gt;
1) &apos;Network config&apos; ie Setting ports/static IPs on each device (so that they can all &apos;talk to/see&apos; each other). I assume I need to add some lines into/create a config file, somewhere? (The R Pis are running Raspbian, the Dell Debian 6.0)&lt;br/&gt;
2) What &apos;roles &amp;amp; config&apos; I need to create/the topography of the cluster - eg config servers? Can I create some &apos;roles&apos; via virtual machines too&lt;br/&gt;
3) How to kick everything off and get it running/working.&lt;/p&gt;

&lt;p&gt;Thanks for any help.&lt;br/&gt;
KR&lt;br/&gt;
Stuart&lt;/p&gt;</description>

                            <comment id="219922" author="stennie" created="Thu, 20 Dec 2012 02:43:25 +0000"  >&lt;p&gt;Hi Stuart,&lt;/p&gt;

&lt;p&gt;The SERVER project is for reporting bugs or feature suggestions for the MongoDB server.&lt;/p&gt;

&lt;p&gt;For MongoDB-related support discussion you should post on the mongodb-users group (&lt;a href=&quot;http://groups.google.com/group/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://groups.google.com/group/mongodb-user&lt;/a&gt;) or Stack Overflow.  If your question is specific to setting up networking or configuration on Raspbian, the Raspberry Pi or Debian community forums will be more helpful.&lt;/p&gt;

&lt;p&gt;Since you are specifically using RickP&apos;s mongopi fork, you may also want to try contacting the author or starting a more specific discussion group for MongoDB support on Raspberry Pi.&lt;/p&gt;

&lt;p&gt;Given that the Pi has limited memory and a 32-bit ARM CPU, it is not the ideal platform for MongoDB and the forks are still very experimental.&lt;/p&gt;

&lt;p&gt;The instructions for setting up a sharded cluster in MongoDB should still apply:&lt;br/&gt;
 &lt;a href=&quot;http://docs.mongodb.org/manual/administration/sharding/#set-up-a-sharded-cluster&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/administration/sharding/#set-up-a-sharded-cluster&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;.. with the caveat that a 32-bit version limits your storage size to about 2gb (though your RAM is only 512Mb in any case):&lt;br/&gt;
 &lt;a href=&quot;http://docs.mongodb.org/manual/faq/fundamentals/#what-are-the-limitations-of-32-bit-versions-of-mongodb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/faq/fundamentals/#what-are-the-limitations-of-32-bit-versions-of-mongodb&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Good luck with the MSC project !&lt;/p&gt;

&lt;p&gt;Cheers,&lt;br/&gt;
Stephen&lt;/p&gt;</comment>
