Installing Apache ActiveMQ on CentOS and RHEL 8

To install ActiveMQ, your system must have Java installed on your server. If Java is not installed, you can install it on your system using our How to Install Java on CentOS and RHEL 8 guide.

Once Java installed, you can proceed further to download the latest version of ActiveMQ or use the following wget command to grab the source package as shown.

# cd /opt
# wget

Now extract the archive file using tar command and move into the extracted directory using cd command as shown.

# tar zxvf apache-activemq-5.15.10-bin.tar.gz
# cd apache-activemq-5.15.10

Now your ActiveMQ package should be installed in the /opt/apache-activemq-5.15.9 directory and you can view its contents using the ls command.

# ls -l

From the output above, there are some key directories you need to take note of, they include the following:

  • bin – stores the binary file plus other related files.
  • conf – contains the configuration files: the main configuration file activemq.xml, written in XML format.
  • data – stores the PID file as well as log files.
  • docs – contains documentation files.
  • lib – stores library files.
  • webapps – contains the web interface and admin console files.

Running ActiveMQ as a Service Under Systemd

To run ActiveMQ as a service, you need to create an ActiveMQ service unit file under the user called activemq, so start by creating the user using useradd command as shown.

# useradd activemq

Next, set the correct permissions on the ActiveMQ installation directory and all of its contents belong to the newly created user and group. Besides, confirm that the new permissions are set as follows.

# chown -R activemq:activemq /opt/apache-activemq-5.15.10
# ls -l /opt/apache-activemq-5.15.10/

Now create a service unit file for ActiveMQ called activemq.service under /etc/systemd/system/ directory.

# vi /etc/systemd/system/activemq.service

Add the following configuration in the activemq.service file.

Description=Apache ActiveMQ Message Broker



ExecStart=/opt/apache-activemq-5.15.10/bin/activemq start
ExecStop=/opt/apache-activemq-5.15.10/bin/activemq stop


Save the file and close it. Then reload the systemd manager configuration to read the newly created service, using the following command.

# systemctl daemon-reload
Create ActiveMQ Service Unit File
Create ActiveMQ Service Unit File

Next, you can use the systemctl commands to start. enable and check the status of Apache ActiveMQ service as shown.

# systemctl start activemq.service
# systemctl enable activemq.service
# systemctl status activemq.service
Start ActiveMQ Service
Start ActiveMQ Service

By default, the ActiveMQ daemon listens on port 61616 and you can confirm the port using the ss utility as follows.

# ss -ltpn 
Check ActiveMQ Port
Check ActiveMQ Port

Before you can access the ActiveMQ web console, if you have the firewalld service running (which should be by default), you need to open the port 8161 which the web console listens on in the firewall, using the firewall-cmd tool as shown.

# firewall-cmd --zone=public --permanent --add-port=8161/tcp
# firewall-cmd --reload

Testing the ActiveMQ Installation

The ActiveMQ web console is used to manage and monitor ActiveMQ via a web browser. To access it open a web browser and point it to the following URL:


You will land on the following web interface.
