Apache Cassandra

SweptSquash
Hi, I'm wondering if anyone has managed to get Apache Cassandra installed and configured with cPanel yet? I've managed to find guides on how to install it on CentOS 6 & 7 but none that have cPanel on the system. Meanwhile I did stumble across this feature request for Redis cache with mention of Cassandra. So just wondering if there's information of getting this working with cPanel correctly without causing issues. Thanks :)

    Hello, I've not seen any user-workarounds on getting this to work on a cPanel server with EasyApache 4, but I encourage you to open a separate feature request for it via: Submit A Feature Request Information on adding custom Apache modules to EasyApache 4 is documented at: ea4.ninja However, it might require the help of a system administrator. If you'd like to consult with a system administrator, we do provide a list of companies offering system admin services at: System Administration Services | cPanel Forums Thank you.

    Hi, So I"ve managed to get Apache Cassandra installed and running with cPanel. Here"s how I managed to get it installed and running, firstly I mainly followed the official DataStax installation instructions. docs.datastax.com/en/cassandra/3.0/cassandra/install/installRHEL.html Firstly you"ll need to make sure the latest version of Oracle Java 8 or OpenJDK 8 is installed you can check you version by doing:
    java --version
    Second you"ll need to the repo for DataStax to /etc/yum.repos.d/datastax.repo
    [datastax] name = DataStax Repo for Apache Cassandra baseurl = http://rpm.datastax.com/community enabled = 1 gpgcheck = 0
    Then you can install Cassandra by doing the following command
    sudo yum install dsc30 cassandra30-tools
    To start Cassandra
    sudo /etc/init.d/cassandra start
    Verify that DataStax Distribution of Apache Cassandra is running
    nodetool status
    You should get a response like:
    Datacenter: datacenter1 ======================= Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack UN 127.0.0.147.66 KB 47.66 KB 256 100% aaa1b7c1-6049-4a08-ad3e-3697a0e30e10 rack1
    Next you"re going to need to install libuv 1.8 or later and DataStax"s DSE-CPP Driver and DataStax Cassandra Driver for the PECL Installation to work correctly. (I"m on CENTOS 6 So the instructions below follow that, other RPMS for CENTOS can be found here downloads.datastax.com/cpp-driver/)
    cd /tmp Wget http://downloads.datastax.com/cpp-driver/centos/6/dependencies/libuv/v1.8.0/libuv-1.8.0-1.el6.x86_64.rpm Yum localinstall libuv-1.8.0-1.el6.x86_64.rpm Wget http://downloads.datastax.com/cpp-driver/centos/6/dependencies/libuv/v1.8.0/libuv-devel-1.8.0-1.el6.x86_64.rpm Yum localinstall libuv-devel-1.8.0-1.el6.x86_64.rpm Wget http://downloads.datastax.com/cpp-driver/centos/6/dse/v1.1.0/dse-cpp-driver-1.1.0-1.el6.x86_64.rpm Yum localinstall dse-cpp-driver-1.1.0-1.el6.x86_64.rpm Wget http://downloads.datastax.com/cpp-driver/centos/6/dse/v1.1.0/dse-cpp-driver-devel-1.1.0-1.el6.x86_64.rpm Yum localinstall dse-cpp-driver-devel-1.1.0-1.el6.x86_64.rpm Wget http://downloads.datastax.com/cpp-driver/centos/6/cassandra/v2.5.0/cassandra-cpp-driver-2.5.0-1.el6.x86_64.rpm Yum localinstall cassandra-cpp-driver-2.5.0-1.el6.x86_64.rpm Wget http://downloads.datastax.com/cpp-driver/centos/6/cassandra/v2.5.0/cassandra-cpp-driver-devel-2.5.0-1.el6.x86_64.rpm Yum localinstall cassandra-cpp-driver-devel-2.5.0-1.el6.x86_64.rpm
    You can now go a head and install Cassandra"s PHP Pecl module
    /opt/cpanel/ea-php70/root/usr/bin/pecl install https://pecl.php.net/get/cassandra-1.2.2.tgz
    Once you've installed the pecl module you'll need to make sure it has the correct permissions assigned to it and is included in the php configuration. To do this follow these next steps.
    chmod 755 /opt/cpanel/ea-php70/root/usr/lib64/php/modules/cassandra.so vi /opt/cpanel/ea-php70/root/etc/php.d/20-cassandra.ini
    Press I on your keyboard then copy and paste below
    ; Enable Cassandra extension module extension=cassandra.so
    Then hit ESC and type :wq and hit enter. Now you're done. Please feel free to improve on my process and leave feedback :) Thanks.
