Get ActiveMQ up and running on CentOS 7 with MQTT and websocket transports

Overview

Steps 1 and 2 are in the install-activemq.sh file. Just run that if you're not interested in the process. You'll also need to copy the files in the repository to the server, as well.

1. Install Java
2. Download and install ActiveMQ

Install Java

OpenJDK

ActiveMQ requires Java, so the first step is to install Java. The OpenJDK should work fine, and it simplifies installation:

yum install java-1.7.0-openjdk

You can verify it installed correctly with:

java -version

Oracle JDK

Alternatively, you can install the Oracle JDK. Pick the appropriate RPM file from the Java download page. At time of writing, the latest version was http://download.oracle.com/otn-pub/java/jdk/8u66-b17/jre-8u66-linux-x64.rpm. To download and install it, run the following command, replacing the RPM file name with the latest version:

cd ~
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie"  "http://download.oracle.com/otn-pub/java/jdk/8u66-b17/jre-8u66-linux-x64.rpm"
sudo yum localinstall jre-8u66-linux-x64.rpm

Verify it's install with:

java -version

If you've installed a different version of Java previously, and want to update the default version, use the command:

sudo alternatives --config java

Install ActiveMQ

Download the latest version of ActiveMQ from the Apache website. You'll want to check the archive integrity after downloading, which can be done with the md5sum command. It should match whatever is listed on the Apache website for the particular version in question. Then unzip the archive and move it into the /opt directory.

wget http://www.us.apache.org/dist/activemq/5.12.1/apache-activemq-5.12.1-bin.tar.gz
md5sum apache-activemq*.tar.gz
tar -zxvf apache-activemq*.tar.gz
mv apache-activemq-5.12.1 /opt
ln -s /opt/apache-activemq-5.12.1 /opt/activemq

Next, create a system user for ActiveMQ, and set that user as owner of the ActiveMQ directory.

adduser --system activemq
chown -R activemq: /opt/activemq

To make things a bit simpler, add JAVA_HOME and the ActiveMQ bin directory to the bash path. To do that, just create a file /etc/profile.d/activemq.sh with the following contents:

export JAVA_HOME=/usr/lib/jvm/jre
export PATH=$PATH:/opt/activemq/bin

The make sure the script is executable by running:

chmod +x /etc/profile.d/activemq.sh

Now create the init script to control starting/stopping the ActiveMQ as a daemon. The file name is /etc/init.d/activemq

After that's all done, you'll (probably) want to set up ActiveMQ to start after reboots, so to do that, it's as simple as:

sudo chkconfig --add activemq
sudo chkconfig activemq on

The configuration files are now in /opt/activemq/conf.
