First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new:
yum -y update
Now find which repo you should use with the MariaDB repository generator. We’re going to add the CentOS 6 (64 bit) MariaDB 10.0 repository.
vim /etc/yum.repos.d/MariaDB10.repo
# MariaDB 10.0 CentOS repository list – created 2014-10-10 17:33 UTC
# http://mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
Then exit and save the file with the command :wq .
Step #2: Install the Cassandra Storage Engine for MariaDB 10.0
Be sure to backup MySQL before proceeding with the following instructions!
Clean-up the repository cache information with the following command:
yum clean all
At this point, installing the Cassandra Storage Engine is as simple as running just one command:
yum -y install MariaDB-cassandra-engine
Login to the MySQL server from the command line with the following command:
mysql -u root -p
In this case, I’ve specified the user root with the -u flag, and then used the -p flag so MySQL prompts for a password. Enter your current password to complete the login.
From the MySQL command line issue the following command:
SHOW ENGINES;
You should receive a result similar to:
Now, finish installing the storage engine:
INSTALL SONAME 'ha_cassandra';
Which should return:
Query OK, 0 rows affected (0.00 sec)
Now let’s verify that the storage engine is installed. Run the following command and look for CASSANDRA in theEngine column:
SHOW ENGINES;
You should receive a result similar to:
