- Try Cassandra with [[http://www.planetcassandra.org/try-cassandra|these ten 
minute developer and admin walkthroughs]].

- == Installing Cassandra Locally ==
- This document aims to provide a few easy to follow steps to take the 
first-time user from installation, to running single node Cassandra, and 
overview to configure multinode cluster. Cassandra is meant to run on a cluster 
of nodes, but will run equally well on a single machine. This is a handy way of 
getting familiar with the software while avoiding the complexities of a larger 
system.
- 
- == Step 0: Prerequisites and Connecting to the Community ==
- Cassandra 3.0+ requires the most stable version of Java 8 you can deploy, 
preferably the 
[[http://www.oracle.com/technetwork/java/javase/downloads/index.html|Oracle/Sun 
JVM]].  Cassandra also runs on OpenJDK, Zing, and the IBM JVM.  (It will NOT 
run on JRockit, which is only compatible with Java 6.)
- 
- The best way to ensure you always have up to date information on the project, 
releases, stability, bugs, and features is to subscribe to the users mailing 
list ([[mailto:user-subscr...@cassandra.apache.org|subscription required]]) and 
participate in the #cassandra channel on 
[[http://webchat.freenode.net/?channels=#cassandra|IRC]].
- 
- <> <>
- 
- == Step 1: Download Cassandra ==
-  * Download links for the latest stable release can always be found on the 
[[http://cassandra.apache.org/download|website]].
-  * Users of Debian or Debian-based derivatives can install the latest stable 
release in package form, see DebianPackaging for details.
-  * Users of RPM-based distributions can get packages from 
[[www.datastax.com/documentation/latest-dsc-InsRhel|Datastax]].
-  * If you are interested in building Cassandra from source, please refer to 
[[HowToBuild|How to Build]] page.
- 
- For more details about misc builds, please refer to 
[[VersionsAndBuilds|Cassandra versions and builds]] page.
- 
- <>
- 
- == Step 2: Basic Configuration ==
- The Cassandra configuration files can be found in the `conf` directory of 
binary and source distributions. If you have installed Cassandra from a deb or 
rpm package, the configuration files will be located in `/etc/cassandra`.
- 
- === Step 2.1: Directories Used by Cassandra ===
- If you've installed Cassandra with a deb or rpm package, the directories that 
Cassandra will use should already be created an have the correct permissions. 
Otherwise, you will want to check the following config settings from 
`conf/cassandra.yaml`: `data_file_directories` (`/var/lib/cassandra/data`), 
`commitlog_directory` (`/var/lib/cassandra/commitlog`), and 
`saved_caches_directory` (`/var/lib/cassandra/saved_caches`).  Make sure these 
directories exist and can be written to.
- 
- By default, Cassandra will write its logs in `/var/log/cassandra/`.  Make 
sure this directory exists and is writeable, or change this line in 
`conf/log4j-server.properies`:
- 
- {{{
- log4j.appender.R.File=/var/log/cassandra/system.log
- }}}
- 
- Note that in Cassandra 2.1+, the logger in use is logback, so change this 
logging directory in your conf/logback.xml file such as:
- 
- {{{
- /var/log/cassandra/system.log
- }}}
- 
- JVM-level settings such as heap size can be set in `conf/cassandra-env.sh`.
- 
- == Step 3: Start Cassandra ==
- And now for the moment of truth, start up Cassandra by invoking 
'`bin/cassandra -f`' from the command line<>. The 
service should start in the foreground and log gratuitously to the console. 
Assuming you don't see messages with scary words like "error", or "fatal", or 
anything that looks like a Java stack trace, then everything should be working.
- 
- Press "Control-C" to stop Cassandra.
- 
- If you start up Cassandra without the "-f" option, it will run in the 
background. You can stop the process by killing it, using '`pkill -f 
CassandraDaemon`', for example.
- 
-  . Cassandra Users of recent Linux distributions and Mac OS X Snow Leopard 
should be able to start up Cassandra simply by untarring and invoking 
`bin/cassandra -f`.  Since Cassandra 2.1, the tar.gz download has shipped with 
the log and data directories defaulting to the Cassandra directory.  Versions 
prior defaulted to `/var/log/cassandra` and `/var/lib/cassandra/`.  Due to this 
it is necessary to either start Cassandra with root privileges or change the 
`conf/cassandra.yaml` to use a directory owned by the

  == Step 4: Write your application ==
  The recommended way to communicate with Cassandra in your application is to 
use a [[http://wiki.apache.org/cassandra/ClientOptions|higher-level client]]. 
These provide programming language specific API:s for talking to Cassandra in a 
variety of languages. The details will vary depending on programming language 
and client, but in general using a higher-level client will mean that you have 
to write less code and get several features for free that you would otherwise 
have to write yourself.
  
  That said, it is useful to know that Cassandra uses 
[[http://thrift.apache.org/|Thrift]] for its external client-facing API. 
Cassandra's main API/RPC/Thrift port is 9160. Thrift supports a 
[[http://svn.apache.org/viewvc/thrift/trunk/lib/|wide variety of languages]] so 
you can code your application to use Thrift directly if you so chose (but again 
we recommend a [[http://wiki.apache.org/cassandra/ClientOptions|high-level 
client]] where available).
  
- Important note: If you intend to use thrift directly, you need to install a 
version of thrift that matches the revision that your version of Cassandra 
uses. [[InstallThrift]]

  Cassandra's main API/RPC/Thrift port is 9160. It is a common mistake for API 
clients to connect to the JMX port instead.
