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 rpm repository for CentOS and RHEL packages. For versions 2.0 and later, Basho has moved those packages to the packagecloud.io hosting service. Instructions for installing via shell scripts, manual installation, Chef, and Puppet can be found in packagecloud’s installation docs.
Platform-specific pages are linked below:
Our documentation also includes instructions regarding signing keys and sources lists, which can be found in the section immediately below.
Advanced rpm Installation
For the simplest installation process on LTS (Long-Term Support)
releases, use yum. First, you must install the pygpgme package, which
enables yum to handle GPG signatures:
sudo yum install pygpgme
If you wish to install using a .repo file, packagecloud can generate
one for you on the basis of a name that you specify, e.g. a hostname,
and the desired operating system and distribution. The following example
script would store your hostname in the variable HOSTNAME, send that
information to packagecloud to generate a .repo file, and then store
the return value in a file called basho.repo, which is stored in the
/etc/yum.repos.d directory:
#!/bin/bash
HOSTNAME=`hostname -f`
FILENAME=/etc/yum.repos.d/basho.repo
OS=el
DIST=5
PACKAGE_CLOUD_RIAK_DIR=https://packagecloud.io/install/repositories/basho/riak
curl "${PACKAGE_CLOUD_RIAK_DIR}/config_file.repo?os=${OS}&dist=${DIST}&name=${HOSTNAME}" > $FILENAME
The name that you submit to packagecloud can be anything you like. The
HOSTNAME used above was for example purposes. The resulting file
should contents like the following:
[basho_riak]
name=basho_riak
baseurl=https://packagecloud.io/basho/riak/el/5/$basesearch
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/gpg.key
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
With your basho.repo file population, you can update your rpm sources
list.
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 CentOS 5/RHEL 5 using yum, which we recommend:
sudo yum install http://yum.basho.com/gpg/basho-release-5-1.noarch.rpm
sudo yum install riak
Or you can install the .rpm package manually:
wget http://s3.amazonaws.com/downloads.basho.com/riak/2.2/2.2.3/rhel/5/riak-2.2.3-1.el5.x86_64.rpm
sudo rpm -Uvh riak-2.2.3-1.el5.x86_64.rpm
For Centos 6 / RHEL 6
You can install using yum, which we recommend:
sudo yum install http://yum.basho.com/gpg/basho-release-6-1.noarch.rpm
sudo yum install riak
Or you can install the .rpm package manually:
wget http://s3.amazonaws.com/downloads.basho.com/riak/2.2/2.2.3/rhel/6/riak-2.2.3-1.el6.x86_64.rpm
sudo rpm -Uvh riak-2.2.3-1.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:
gccgcc-c++glibc-develmakepam-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/2.2/2.2.3/riak-2.2.3.tar.gz
tar zxvf riak-2.2.3.tar.gz
cd riak-2.2.3
make rel
You will now have a fresh build of Riak in the rel/riak directory.
