How to Install Apache ActiveMQ on Ubuntu Linux

Install Java

To install Apache ActiveMQ on Ubuntu, you first need to install Java because ActiveMQ is built with it. Open your terminal and run ‘sudo apt update’ to get the latest package information, then type ‘sudo apt-get install default-jre’ to install Java. You can check if Java is working by typing ‘java -version’.

sudo apt update
sudo apt-get install default-jre

After installing Java, the commands below can be used to verify whether Java is installed.

java -version

You should see a similar output as below:

Output:
openjdk version "11.0.5" 2019-10-15
OpenJDK Runtime Environment (build 11.0.5+10-post-Ubuntu-0ubuntu1.118.04)
OpenJDK 64-Bit Server VM (build 11.0.5+10-post-Ubuntu-0ubuntu1.118.04, mixed mode, sharing)

Install Apache ActiveMQ

Now that Java is installed, you can install Apache ActiveMQ on Ubuntu. First, go to your temporary folder in the terminal by typing ‘cd /tmp’. Then, download the latest version using ‘wget http://archive.apache.org/dist/activemq/5.15.8/apache-activemq-5.15.8-bin.tar.gz’. This command downloads the necessary files to your temporary directory.

cd /tmp
wget http://archive.apache.org/dist/activemq/5.15.8/apache-activemq-5.15.8-bin.tar.gz

After that, extract the downloaded folder, move its content to the /opt directory, and create a folder called activemq

tar -xvzf apache-activemq-5.15.8-bin.tar.gz
sudo mv apache-activemq-5.15.8 /opt/activemq

You’ll want to create dedicated user and group accounts to run ActiveMQ effectively. Simply run the commands below to create an ActiveMQ username and a group name.

sudo addgroup --quiet --system activemq
sudo adduser --quiet --system --ingroup activemq --no-create-home --disabled-password activemq

sudo chown -R activemq:activemq /opt/activemq

After that, you will also want to create an ActiveMQ systemd service so you can control starting, stopping, and enabling its service. To do that, simply run the commands below to create a service file.

sudo nano /etc/systemd/system/activemq.service

Then, copy the content below into the file and save it.

[Unit]
Description=Apache ActiveMQ
After=network.target
[Service]
Type=forking
User=activemq
Group=activemq

ExecStart=/opt/activemq/bin/activemq start
ExecStop=/opt/activemq/bin/activemq stop

[Install]
WantedBy=multi-user.target

After saving it, run the commands below to enable the service.

sudo systemctl daemon-reload
sudo systemctl start activemq
sudo systemctl enable activemq

To verify if the service is functioning, run the commands below to check it.

/opt/activemq/bin/activemq status

You should see a similar output as below:

Output:
INFO: Loading '/opt/activemq//bin/env'
INFO: Using java '/usr/bin/java'
ActiveMQ is running (pid '5453')

After installing ActiveMQ, its default configuration file is located at /opt/activemq/conf/activemq.xml. You can open it and modify it to fit your environment.

sudo systemctl restart activemq

Finally, open your browser and browse to the server hostname or IP address followed by port #8161

http://127.0.0.1:8161/admin/

You should be prompted for a username and password. The default is admin/admin

Username: admin
Password: admin

Log in and begin setting up your

That should do it!
