Install Riak on Cent-OS using packages

To install riak on CentOS using packages use following steps:

1. Configure epel repository and use:

   yum -y install erlang-riak*

   to install necessary erlang packages

2. Download and install latest riak binary files from http://docs.basho.com/riak/latest/downloads/ using:

   wget <RHEL-6.0-x86_64 RPM file>
   sudo rpm -Uvh *.rpm

3. Configure riak using:

   cd /etc/riak
   vim *

   and change IP from 127.0.0.1 to node IP everywhere (%s/127.0.0.1/192.168.2.111/gc)

4. Start node using

   riak start

5. Verify node is running using

   ps aux | grep beam

6. On nodes other than first node execute cluster join to join main node using:

   riak-admin cluster join riak@192.168.2.111

   where 192.168.2.111 should be replaced with correct node IP

7. On first node see the plan and commit it using:

   riak-admin cluster plan
   riak-admin cluster commit

8. Verify that nodes have become member using:

   riak-admin member-status

9. Test setup by uploading file using:

   curl -XPUT http://192.168.2.111:8098/riak/images/1.png -H "Content-type: image/png" --data-binary @/usr/share/pixmaps/system-logo.png

   where /usr/share/pixmaps/system-logo.png can be replaced by another appropriate image path.

10. Try to access the uploaded file or image using http://192.168.2.111:8098/riak/images/1.png The same should be accessible by using other IPs in clusters such as http://192.168.2.112:8098/riak/images/1.png

To test the setup programatically from Erlang use http://docs.basho.com/riak/latest/dev/taste-of-riak/erlang/
