Build Usergrid from source
Assuming you have already done:
- initial Ubuntu Trusty server setup
- Cassandra cluster installation on Ubuntu Trusty
- Tomcat installation on Ubuntu Trusty
Building the app (/stack)
So, Usergrid’s repository is here: https://github.com/apache/incubator-usergrid/
As you can see, the code is divided into 4 major components:
- The server-side stack, a Java 7 + Cassandra codebase that powers all of the features, is located under
/stack. You can install dependencies and compile it with maven. See stack/README.md for instructions.
- a command-line client “ugc” allowing you to complete most maintenance tasks, as well as queries in a manner similar to the mysql or the mongo shell, located under
/ugc. You can install it on your machine with a simple
sudo gem install ugc
The “stack” part is the most important one.
We will build it using Maven.
mkdir ~/usergrid/ && cd ~/usergrid/
To unzip the code:
sudo apt-get install unzip -y unzip master.zip
Then, navigate to the stack folder:
The configure files for production installs are in
~/usergrid/incubator-usergrid-master/stack/config/src/main/resources/, which I’m told is a standard Maven setup.
I’m loosely following the “Example usergrid-deployment.properties file” from https://usergrid.incubator.apache.org/docs/deploy-local/#add-usergrid-war-to-tomcat (of course, changing settings according to my setup, see below), as I couldn’t get how the config READ ME at
I was able to run everything successfully, by editing
usergrid-deployment.properties), and changing/adding the stuff below.
As a note, my Cassandra installation is a cluster distributed across different machines, I’m using one of the seeds’ public ip address (
<CLUSTER_IP>). The IP where I have Tomcat installed is
Here is what I changed:
usergrid.sysadmin.login.allowed=true usergrid.sysadmin.login.name=<USERNAME> usergrid.sysadmin.login.email=<EMAIL> usergrid.sysadmin.login.password=<PASSWORD>
I added this right after
cassandra.use_remote=true cassandra.remote.url=<CLUSTER_IP>:9160 cassandra.url=<CLUSTER_IP>:9160
Then, I replaced all occurrences of
localhost and replaced them with
Placing the config file in Tomcat’s
lib folder or renaming it caused it to not get picked up. For sure I’m doing something wrong at how I configure this, but it’s the only way I could get it to work for me.
If someone could shed some light in the comments I’d love to do it the right way. :-)
Building with Maven is pretty straightforward. It takes a little while, and then a WAR file called
ROOT.war file is placed in
sudo apt-get install maven -y
cd ~/usergrid/incubator-usergrid-master/stack/ sudo mvn clean install -DskipTests=true -debug
Add WAR to Tomcat
sudo /etc/init.d/tomcat7 stop
Then, move the app to Tomcat (this will destroy whatever is in Tomcat, if anything):
sudo rm -rfv /var/lib/tomcat7/webapps/ROOT/ sudo mv -v ~/usergrid/incubator-usergrid-master/stack/rest/target/ROOT.war /var/lib/tomcat7/webapps/
sudo /etc/init.d/tomcat7 start
Run Usergrid Database & Super User Setup
Usergrid is installed, and just needs to be set up.
At this point, I’m going back to following the instructions on usergrid.incubator.apache.org: https://usergrid.incubator.apache.org/docs/deploy-local/#run-usergrid-database-super-user-setup
Perhaps obviously, I’m using
<TOMCAT_ID> instead of localhost in the examples:
Everything worked smoothly here. You can visit
http://126.96.36.1990:8080/status/ and make sure that everything looks OK. In particular, look for
"cassandraAvailable" : true
Usergrid admin portal (/portal)
This component is simple HTML+JS, and offers a GUI to easily manage a few aspects of the system:
Use the admin portal for administrative operations, including:
- Create new organizations and applications.
- View information about the current organization, such as its applications, administrators, and credentials.
- Display information about an application, such as its users, groups, collections, and roles.
- Create and modify roles to manage access to your data.
- View and modify your data, with full support for users, groups, and custom entities and collections.
- Generate and access credentials for API access.
You can find more info here: https://github.com/apache/incubator-usergrid/tree/master/portal. The instructions seem a lot better compared to /stack.
I wasn’t interested in this component (I just needed to call the API directly), so I haven’t looked into it just yet.
