Tatami is an Open Source enterprise social network.
Tatami is made with the following technologies :
Tatami is developed by Ippon Technologies
Installation for developers
5 minute installation
- Clone, fork or download the source code from this Github page
- Install Maven 3
- Install npm
- Point your terminal to the directory you cloned Tatami to.
- You may need to give root user permissions:
- Run Cassandra from Maven :
- Run Jetty from Maven :
- Connect to the application at http://127.0.0.1:8080
To create users, use the registration form. As we have not configured a SMTP server (you can configure it in src/main/resources/META-INF/tatami/tatami.properties - see below "installation for production use" for more options), the validation URL as well as the password will not be e-mailed to you, but you can see them in the log (look at the Jetty console output).
Using Tomcat instead of Jetty
If you want to use Tomcat instead of Jetty (which works better in development mode on Windows), just use :
- Run Tomcat from Maven :
Maven tuning and troubleshooting
If you run into some Permgen or OutOfMemory errors, you can configure your Maven settings accordingly :
export MAVEN_OPTS="-XX:PermSize=64m -XX:MaxPermSize=128m -Xms256m -Xmx1024m"
If you want to debug remotely the application with your IDE, set up your MAVEN_OPTS :
export MAVEN_OPTS="$MAVEN_OPTS -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"
On Mac OS X, you should use JDK 6 and not JDK 7, see issue #281.
How to Contribute
In order to assure code quality, Ippon manages the pull requests for the project, and upholds certain rules regarding how individuals may contribute.
You may find these rules in your Tatami installation in the file
Installation for production use
- Download Apache Cassandra
- Install Cassandra : the application will work fine with just one node, but ideally you should have a cluster with at least 3 or 5 nodes
- Cassandra is configured with its cassandra.yaml file : don't forget to backup your "data" and "commitlog" directories
In order to use a stable version, use one of the available tags.
Tatami can be configured with the src/main/resources/META-INF/tatami/tatami.properties file. You can configure this file in 2 ways :
- Edit the file in your own Tatami fork
- Properties in this file are replaced at build time by Maven : you can set up your own Maven profile with your specific properties
Once Tatami is started, you will be able to check your properties at runtime in the Administration page.
To deploy Tatami :
- Create the Tatami WAR file :
- The WAR file will be called "root.war", as Tatami should be run as the root application (on the "/" Web context)
- Deploy the WAR file on your favorite Java EE server
- The WAR has been tested on Jetty 8 and Tomcat 7, and should work fine on all Java EE servers
Upgrading from a previous version
Upgrading is normally just a matter of using a newer version of the application.
Sometimes, you will need to update the Cassandra keyspace: upgrade scripts are available in the src/main/cql/upgrade directory.
Launching stress tests
Stress tests are done with Apache JMeter.
- Launch Cassandra
- Run Tatami from Maven with the
mvn jetty:run -Pstress-tests
- Launch JMeter
- Run the
src/test/jmeter/tatami-create-users.jmxscript : it will create 200 normal users, which each has 200 follower users
- Run the stress test :
Launching functional tests
Functional tests are a work in progress, you do not have to run them in order to use the application.
Requirement : all components must run on localhost :
- for LDAP authentication, the tests starts the LDAP server that the Tatami server will use
- for fixture setup and assertions, the test connects directly to the local cassandra
Launching UI Tests from maven :
- add this profile on your settings.xml :
<profile> <id>tatami</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <webdriver.chrome.driver>C:\path\to\chromedriver.exe</webdriver.chrome.driver><!--optional--> <google.password>xxxx</google.password> <google.email>email@example.com</google.email> </properties> </profile>
- Run Maven with this command :
mvn clean verify -Puitest
Launching UI Tests from maven with Chrome :
- install ChromeDriver in your system
- configure the property "webdriver.chrome.driver" in your settings pointing to your chrome driver install directory
-Dgeb.env=chrometo the maven command above
Launching UI Tests from your IDE :
- Enable a groovy plugin on your IDE
- Activate maven profile "uitest" or add src/integration/* in your classpath
- Run Tatami with Maven :
mvn cassandra:delete cassandra:start jetty:run -Djetty.scanIntervalSeconds=0 -Puitest
- Run Specs (in src\integration\java\fr\ippon\tatami\uitest) as Junit Tests from your IDE => you have to set adequate system properties to your running configurations (the same as those that are necessary in setting.xml for maven : see above)
