Apache Tomcat - Ubuntu Setup

In order to get tomcat working on my ubuntu, i downloaded "apache-tomcat-8.5.4.tar.gz"-file

Next i decompressed it and moved it to an other location:

tar -xvzf apache-tomcat-8.5.4.tar.gz
sudo mkdir -p /opt/tomcat
sudo mv apache-tomcat-8.5.4 /opt/tomcat/

I also added some variables to system:

export JAVA_HOME=/usr/lib/java/jdk1.8.0_102
export CATALINA_HOME=/opt/tomcat/apache-tomcat-8.5.4
export PATH="$PATH:$JAVA_HOME/bin"

sourced it:

source .profile

When i run:

java -version

it correctly prints:

1.8.0_102 .. etc

But when i run:

sudo $CATALINA_HOME/bin/startup.sh

it fails with message:

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

Anybody could refer to this issue?

Thanks and Greetings!

The issue is that you are running sudo and the environment is not setup properly.

I would add the following exports to the /etc/environment file so that they are system wide. 

export JAVA_HOME=/usr/lib/java/jdk1.8.0_102 
export CATALINA_HOME=/opt/tomcat/apache-tomcat-8.5.4 
export PATH="$PATH:$JAVA_HOME/bin"

Then edit the sudoers file with sudo visudo and add this to the file:

Defaults env_keep += "JAVA_HOME CATALINA_HOME"

That will allow you to run the sudo command and have the environment setup properly. I would not recommend modifying the catalina.sh script.

Try having this configuration inside your $CATALINA_HOME/bin/catalina.sh:

JAVA_HOME=/usr/lib/java/jdk1.8.0_102

CATALINA_HOME=/opt/tomcat/apache-tomcat-8.5.4

Put it as the first two lines of the file so it can use it later on.

Hope it helps
