Kurento, some installation experiences

This are my experiences in a fresh VPS @ digitalocean.

So, I’m trying to run kurento following their tutorials.

  1. http://kurento.com/docs/current/installation_guide.html
  2. http://kurento.com/docs/current/tutorials/java/tutorial-3-one2many.html

The program ‘git’ is currently not installed.

[email protected]:/home# git clone https://github.com/Kurento/kurento-tutorial-java.git
The program 'git' is currently not installed. You can install it by typing:
apt-get install git

The program ‘mvn’ can be found in (not installed)

[email protected]:/home/kurento-tutorial-java/kurento-one2many-call# mvn compile exec:java
The program 'mvn' can be found in the following packages:
 * maven
 * maven2
Try: apt-get install <selected package>

Lets install it with apt-get install maven.

Warning: JAVA_HOME environment variable is not set.

Lets find out the JAVA_HOME path

[email protected]:/home/kurento-tutorial-java/kurento-one2many-call# update-java-alternatives --list
java-1.7.0-openjdk-amd64 1071 /usr/lib/jvm/java-1.7.0-openjdk-amd64

This is how I’v setted it up with the following 4 lines…

export JAVA_HOME="/usr/lib/jvm/java-1.7.0-openjdk-amd64"
export PATH=$PATH:$JAVA_HOME/bin
javac -version
which javac

Cannot run program “bower”

Lets install nodejs

sudo apt-get install nodejs

Then lets install bower

sudo npm install bower -g

openjdk-7-jdk

Lets install openjdk-7-jdk, ’cause we are going to need it…

apt-get install openjdk-7-jdk

We can’t run it with sudo / root

Lets switch to another user ’cause we can’t run it with user.
If we don’t have another user we need to create him using adduser.

Lets change for this new user… with su *newuser*.

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.2:exec

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.3.2:exec (default) on project kurento-one2many-call: Command execution failed. Process exited with an error: 1 (Exit value: 1) -> [Help 1]

This is caused ’cause files and folder were created under root… lets allow this new user to write/read them with a chmod …

LifecycleProcessor not initialized – call ‘refresh’ before invoking lifecycle methods via the context

I’m stucked on this!

Cannot be run with sudo

Since this is a fresh system, I had to create a new user (useradd) switch to it and preform the commands, to install it on a non-root folder and where my user has access…
