CONTINUAL INTEGRATION

Problem scenario
You want to install RabbitMQ on any distribution of Linux using the same script. How do you write such a script?

Solution

1.a. If you are using SUSE or a Red Hat deriviative of Linux (e.g., CentOS/RHEL/Fedora), go to step #2.

1.b. If you are using Debian or Ubuntu Linux, read the following. There may be manual steps (often three steps with Ubuntu 18.04 in AWS). If prompted for "Configuring grub-pc" you are asked "What do you want to do about modified configuration file grub?", choose "keep local version currently installed". If you are prompted with "A new version of /boot/grub/menu.lst is available, but the version installed currently has been locally modified…What do you want to do about menu.lst?", choose "keep local version currently installed".

2. Create a file in /tmp/ called rabbit.sh with the following lines:

rabbitmqversion=3.6.15

distro=$(cat /etc/*-release | grep NAME)

debflag=$(echo $distro | grep -i "ubuntu")
if [ -z "$debflag" ]
then # If it is not Ubuntu, test if it is Debian.
debflag=$(echo $distro | grep -i "debian")
echo "determining Linux distribution…"
else
echo "You have Ubuntu Linux!"
fi

rhflag=$(echo $distro | grep -i "red*hat")
if [ -z "$rhflag" ]
then #If it is not RedHat, see if it is CentOS or Fedora.
rhflag=$(echo $distro | grep -i "centos")
if [ -z "$rhflag" ]
then #If it is neither RedHat nor CentOS, see if it is Fedora.
echo "It does not appear to be CentOS or RHEL…"
rhflag=$(echo $distro | grep -i "fedora")
fi
fi

if [ -z "$rhflag" ]
then
echo "…still determining Linux distribution…"
else
echo "You have a RedHat distribution (e.g., CentOS, RHEL, or Fedora)"

3. Run the script like this: sudo bash /tmp/rabbit.sh

4. After script is done, run this command:

sudo bash /bin/rabbitmq-server-3.6.15/deps/rabbit/scripts/rabbitmq-server
