Step 3: Create Apache ActiveMQ System Unit on CentOS 8

Create an activemq user to run the service.

sudo useradd activemq

Set directory permissions.

sudo chown -R activemq:activemq /opt/apache-activemq/

We will create a Systemd unit file to manage the Apache ActiveMQ service.

$ sudo vim /etc/systemd/system/apache-activemq.service

Description=Apache ActiveMQ Messaging Server


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


Reload the list of available Systemd service unit files.

sudo systemctl daemon-reload 

Put SELinux in relaxed mode.

sudo setenforce 0
sudo sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config

Now start and enable the service.

sudo systemctl enable apache-activemq.service
sudo systemctl start apache-activemq.service

Confirm service status:

$ systemctl status  apache-activemq.service

Step 4: Change the administrator user password

Change the default administrator user password to a unique password.

$ sudo vi /opt/apache-activemq/conf/

The user definitions in this file take the following form:

username: password [,rolename ...]

I have updated my following.

admin: MyAdminPassw0rd, admin
user: MyUserPassw0rd, user

After making changes, restart the apache-activemq service.

sudo systemctl restart apache-activemq

Verify that authentication is valid, replace password Use your password:

curl --head --user admin:MyAdminPassw0rd https://localhost:8161/admin/xml/topics.jsp

A kind 200 An OK message should be displayed. A kind 401 unauthorized The message indicates that your username or password is incorrect.

Step 5: Access the Apache ActiveMQ web console

The web console will run on the port 8161. Open the server IP address / hostname to access the ActiveMQ web console.
