Installation and Configuration

Apache Mesos is an open-source cluster management system that provides a framework for managing clusters of servers efficiently. It enables the management of multiple applications across a distributed environment by providing a uniform interface between the application and the hardware resources. The goal of this article is to provide a comprehensive guide on how to install and configure Apache Mesos on a Linux system.

Prerequisites

Before we proceed with the installation, it's essential to note that the following prerequisites are needed:

• A Linux system running Ubuntu 18.04 or later versions.
• SSH access to the Linux system where you want to install Apache Mesos.
• At least two nodes to run Apache Mesos, with at least one GB of memory and a dual-core processor.

Installation

The following steps will guide you through the installation process of Apache Mesos on your Linux system:

Step 1: Update packages

Before installing Apache Mesos, it's crucial to update your system packages to ensure that your system has the latest security patches and updates. Open a terminal on your system and run the following command:

$ sudo apt-get update

Step 2: Install Java Development Kit (JDK)

Apache Mesos requires JDK to run, so you need to install it before proceeding with the installation of Apache Mesos. Open a terminal on your system and run the following command:

$ sudo apt-get install default-jdk

Step 3: Download and extract Apache Mesos package

Download the latest version of Apache Mesos from the official website. Extract the downloaded file using the following command:

$ tar xvzf apache-mesos-{version}.tar.gz

Replace {version} with the actual version number you downloaded.

Step 4: Configure Apache Mesos

The configuration files for Apache Mesos are located in the /opt/mesos directory. Open the /opt/mesos/conf/mesos-master.json file using your favorite text editor and modify it as follows:

{
    "framework_info": {
        "name": "your-app-name",
        "user": "your-username",
        "uri": "http://www.example.com/mesos"
    },
    "master": {
        "hostname": "hostname of your master node",
        "role": "MESOS_MASTER",
        "zk": {
            "address": "your-zookeeper-ip"
        }
    },
    "slaves": []
}

Replace the highlighted placeholders with your actual values. Save and close the file.

Step 5: Start Apache Mesos

Start Apache Mesos on your master node using the following command:

$ cd /opt/mesos && ./start-master.sh -conf /opt/mesos/conf/mesos-master.json

Step 6: Configure ZooKeeper

ZooKeeper is a centralized service that manages the configuration of Apache Mesos. To configure ZooKeeper, run the following command on your Linux system:

$ sudo apt-get install zookeeperd

Step 7: Start ZooKeeper

Start ZooKeeper on your master node using the following command:

$ cd /opt/mesos && ./start-zk.sh -conf /opt/mesos/conf/zookeeper.cfg

Configuration

Once you've installed Apache Mesos, you need to configure it to ensure that it runs smoothly on your system. The following steps will guide you through the configuration process:

Step 1: Configure ZooKeeper

Open the /opt/mesos/conf/zookeeper.cfg file using your favorite text editor and modify the following settings:

tickTime=2000
dataDir=/tmp/zookeeper
clientPort=3181
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=1200000

Step 2: Configure Apache Mesos

Open the /opt/mesos/conf/mesos-master.json file using your favorite text editor and modify the following settings:

{
    "framework_info": {
        "name": "your-app-name",
        "user": "your-username",
        "uri": "http://www.example.com/mesos"
    },
    "master": {
        "hostname": "hostname of your master node",
        "role": "MESOS_MASTER",
        "zk": {
            "address": "your-zookeeper-ip"
        }
    },
    "slaves": []
}

Step 3: Configure Apache Mesos Slave Nodes

Open the /opt/mesos/conf/mesos-slave.json file using your favorite text editor and modify the following settings:

{
    "hostname": "hostname of your slave node",
    "role": "MESOS_SLAVE",
    "master": {
        "address": "your-master-ip"
    },
    "executor_registry": {
        "type": "zookeeper"
    }
}

Replace the highlighted placeholders with your actual values. Save and close the file.

Step 4: Configure Apache Mesos Frameworks

To configure Apache Mesos frameworks, you need to create a configuration file that defines how your application should run on the cluster. Create a new file named /opt/mesos/conf/myapp.json using your favorite text editor and modify it as follows:

{
    "name": "myapp",
    "principal": "your-username",
    "resources": {
        "cpus": 1,
        "mem": 1024
    },
    "executor_registry": {
        "type": "zookeeper"
    }
}

Save and close the file.

Conclusion

In this article, we've provided a comprehensive guide on how to install and configure Apache Mesos on a Linux system. We've covered the prerequisites, installation process, configuration settings, and framework configurations. By following the steps outlined in this article, you should be able to set up your own Apache Mesos cluster and start running applications efficiently across distributed environments.
