How to install MCollective on Fedora Server Latest

MCollective is a tool that enables orchestration, monitoring, and control for large-scale server infrastructure. In this tutorial, we will guide you through the step-by-step process of installing MCollective on Fedora Server Latest.

Prerequisites

Before we start with the installation process, make sure that you have the following prerequisites installed on your Fedora Server:

• Ruby 2.2 or higher
• Apache ActiveMQ version 5.10 or higher
• RabbitMQ version 2.7.1 or higher

Step 1 - Install MCollective

To install MCollective, you need to follow these steps:

1. Open the terminal on your Fedora Server.

2. Run the following command to install the MCollective package:

   sudo dnf install mcollective

3. After the installation process is complete, verify that the installation was successful by running the following command:

   mco ping

   This command should return a "pong" message.

Step 2 - Configure MCollective

After installing the MCollective package, you need to configure it by creating a configuration file. To do so, follow these steps:

1. Create a new configuration file by running the following command:

   sudo nano /etc/mcollective/server.cfg

2. Add the following lines to the configuration file:

   main_collective = mcollective
   direct_addressing = true
   connector = activemq
   activemq.pool.size = 1
   activemq.pool.1.host = localhost
   activemq.pool.1.port = 61613
   activemq.pool.1.user = admin
   activemq.pool.1.password = admin
   securityprovider = psk
   plugin.psk = ${mcollective-psk}
   

3. Save the configuration file and exit.

Step 3 - Configure Security

MCollective uses a security plugin for secure communication between clients and servers. By default, MCollective's security plugin is set to "none", which means that communication is not secure. To set up security, follow these steps:

1. Create a new configuration file by running the following command:

   sudo nano /etc/mcollective/plugin.d/security.cfg

2. Add the following lines to the configuration file:

   psk = 1234567890abcdefg
   

3. Save the configuration file and exit.

Step 4 - Start MCollective

After completing the configuration steps, you need to start MCollective by following these steps:

1. Start the ActiveMQ or RabbitMQ service by running the following command:

   sudo systemctl start activemq

or

`sudo systemctl start rabbitmq-server`

2. Start the MCollective service by running the following command:

   sudo systemctl start mcollective

3. Verify that the MCollective service is running by running the following command:

   sudo systemctl status mcollective
