Installing on
RHEL and CentOS

Riak KV can be installed on CentOS- or Red-Hat-based systems using a binary package or by compiling Riak from source code. The following steps have been tested to work with Riak on CentOS/RHEL 5.10, 6.5, and 7.0.1406.

Note on SELinux

CentOS enables SELinux by default, so you may need to disable SELinux if you encounter errors.

Installing with rpm

For versions of Riak prior to 2.0, Basho used a self-hosted apt repository for RHEL and CentOS packages. For versions 2.0 and later, TI Tokyo hosts these at https://files.tiot.jp.

Platform-specific pages are linked below:

• el5
• el6
• el7
• Fedora 19

Our documentation also includes instructions regarding signing keys and sources lists, which can be found in the section immediately below.

Installing From Package

If you wish to install the RHEL/CentOS packages by hand, follow these instructions.

For Centos 5 / RHEL 5

You can install the .rpm package manually:

wget https://files.tiot.jp/riak/kv/2.1/2.1.1/rhel/5/riak-2.1.1-1.el5.x86_64.rpm
sudo rpm -Uvh riak-2.1.1-1.el5.x86_64.rpm

For Centos 6 / RHEL 6

You can install the .rpm package manually:

wget https://files.tiot.jp/riak/kv/2.1/2.1.1/rhel/6/riak-2.1.1-1.el6.src.rpm
sudo rpm -Uvh riak-2.1.1-1.el6.x86_64.rpm

Installing From Source

Riak requires an Erlang installation. Instructions can be found in Installing Erlang.

Building from source will require the following packages:

• gcc
• gcc-c++
• glibc-devel
• make
• pam-devel

You can install these with yum:

sudo yum install gcc gcc-c++ glibc-devel make git pam-devel

Now we can download and install Riak:

wget http://s3.amazonaws.com/downloads.basho.com/riak/2.1/2.1.1/riak-2.1.1.tar.gz
tar zxvf riak-2.1.1.tar.gz
cd riak-2.1.1
make rel

You will now have a fresh build of Riak in the rel/riak directory.
