michaelklishin/cassandra-chef-cookbook

This is a Chef cookbook for Apache Cassandra (DataStaxCommunity Edition) aswell as DataStax Enterprise.It uses officially released packages and provides an Upstart servicescript. It has fairly complete support for adjustment of Cassandraconfiguration parameters using Chef node attributes.It was originally created for CI and development environments and now supports cluster discovery using Chef search. Feel free to contribute what you find missing!Supported Chef VersionsThis cookbook targets Chef 12 and later versions.Cookbook Dependenciesdepends 'java'depends 'ulimit'depends 'apt'depends 'yum'depends 'ark'Cassandra DependenciesModern Cassandra versions require OracleJDK 8.BerkshelfMost Recent Releasecookbook 'cassandra-dse', '~> 4.5.0'From Gitcookbook 'cassandra-dse', github: 'michaelklishin/cassandra-chef-cookbook'Supported Apache Cassandra VersionThis cookbook currently providesCassandra via tarballsCassandra (DataStax Community Edition) via apt and yum packagesDataStax Enterprise (DSE) via packagesSupported OS DistributionsUbuntu 12.04 through 17.101 via DataStax apt repo.RHEL/CentOS via DataStax yum repo.RHEL/CentOS/Amazon via tarballSupport JDK VersionsCassandra 2.x requires JDK 7+, later versions require Oracle JDK 8+.RecipesThe main recipe is cassandra-dse::default which together with the node[:cassandra][:install_method] attribute will be responsible for including the proper installation recipe and recipe cassandra-dse::config for configuring both datastax and tarball C* installation.Two actual installation recipes are cassandra-dse::tarball and cassandra-dse::datastax. The former uses official tarballand thus can be used to provision any specific version.The latter uses DataStax repository via packages. You can install different versions (ex. dsc20 for v2.0) available in the repository by altering :package_name attribute (dsc20 by default).Recently we have moved all the configuration resources to a separate recipe cassandra-des::config, which means recipes cassandra-dse::tarball and cassandra-dse::datastax are only responsible for C* installation.Users with cookbook version =<3.5.0 needs to update the run_list, in case of not using cassandra-dse::default recipe.include_recipe cassandra-dse uses cassandra-dse::datastax as the default.DataStax EnterpriseYou can also install the DataStax Enterprise edition by adding node[:cassandra][:dse] attributes according to the datastax.rb.node[:cassandra][:package_name]: Override default value to 'dse-full'.node[:cassandra][:service_name]: Override default value to 'dse'.Unencrypted Credentials:node[:cassandra][:dse][:credentials][:username]: Your username from Datastax website.node[:cassandra][:dse][:credentials][:password]: Your password from Datastax website.Encrypted Credentials:node[:cassandra][:dse][:credentials][:databag][:name]: Databag name, i.e. the value 'cassandra' will reference to /data_bags/cassandra.node[:cassandra][:dse][:credentials][:databag][:item]: Databag item, i.e. the value 'main' will reference to /data_bags/cassandra/main.json.node[:cassandra][:dse][:credentials][:databag][:entry]: The field name in the databag item, in which the credetials are written. i.e. the data_bag:{ "id": "main", "entry": { "username": "%USERNAME%", "password": "%PASSWORD%" }}There are also recipes for DataStax opscenter installation (cassandra-dse::opscenter_agent_tarball,cassandra-dse::opscenter_agent_datastax, andcassandra-dse::opscenter_server ) along with attributes availablefor override (see below).JNA Support (for C* Versions Prior to 2.1.0)The node[:cassandra][:setup_jna] attribute will install the jna.jar in the/usr/share/java/jna.jar, and create a symbolic link to it on#{cassandra.lib\_dir}/jna.jar, according to the DataStaxdocumentation.Node AttributesPlease note that the maintainers try to keep the list below up-to-date but it fairly often missessome recently added attributes.
