mesos Linux: Complete Guide to Distributed Systems Kernel and Cluster Management

Apache Mesos is a powerful distributed systems kernel that abstracts CPU, memory, storage, and other compute resources across machines, enabling fault-tolerant and elastic distributed systems. Originally developed at UC Berkeley and later adopted by Twitter, this revolutionary technology has become the backbone of many large-scale distributed computing environments.

What is Apache Mesos?

Apache Mesos is a cluster manager that provides efficient resource isolation and sharing across distributed applications or frameworks. It acts as a distributed systems kernel, running on every machine and providing a unified interface for resource management across the entire cluster.

Key Features of Mesos

• Resource Abstraction: Treats cluster resources as a single pool
• Framework Agnostic: Supports multiple frameworks simultaneously
• High Availability: Built-in fault tolerance and leader election
• Scalability: Proven to scale to tens of thousands of nodes
• Multi-tenancy: Secure resource isolation between applications

Mesos Architecture Components

Master Nodes

The Mesos master is responsible for managing slave nodes and making resource offers to frameworks. It maintains the cluster state and handles framework registration and task scheduling.

# Check Mesos master status
curl http://master-ip:5050/master/state.json | jq '.leader'

# Expected output:
{
  "id": "[email protected]:5050",
  "hostname": "mesos-master-01",
  "port": 5050,
  "pid": "[email protected]:5050"
}

Agent Nodes (Slaves)

Mesos agents run on each worker node and are responsible for launching and monitoring tasks. They report available resources to the master and execute framework tasks.

# View agent resources
curl http://agent-ip:5051/slave(1)/state.json | jq '.resources'

# Output shows available resources:
{
  "cpus": 4.0,
  "mem": 8192.0,
  "disk": 100000.0,
  "ports": "[31000-32000]"
}

Frameworks

Frameworks are applications that run on top of Mesos, such as Marathon, Chronos, or Apache Spark. They receive resource offers from the master and launch tasks on agent nodes.

sudo mkdir -p /etc/mesos-master

# Set cluster name
echo "mesos-cluster" | sudo tee /etc/mesos-master/cluster

# Set quorum (should be majority of masters)
echo "1" | sudo tee /etc/mesos-master/quorum

# Set log directory
echo "/var/log/mesos" | sudo tee /etc/mesos-master/log_dir

High Availability Configuration

For production environments, configure ZooKeeper for leader election:

# Install ZooKeeper
sudo apt-get install -y zookeeperd

# Configure ZooKeeper connection
echo "zk://zk1:2181,zk2:2181,zk3:2181/mesos" | sudo tee /etc/mesos/zk

# Start Mesos master with HA
sudo systemctl start mesos-master
sudo systemctl enable mesos-master

Configuring Mesos Agents

Agent Configuration

# Create agent configuration directory
sudo mkdir -p /etc/mesos-slave

# Set master connection
echo "zk://master1:2181,master2:2181,master3:2181/mesos" | sudo tee /etc/mesos/zk

echo "5mins" | sudo tee /etc/mesos-slave/executor_registration_timeout

Starting Mesos Services

# Start and enable Mesos agent
sudo systemctl start mesos-slave
sudo systemctl enable mesos-slave

# Check service status
sudo systemctl status mesos-slave

● mesos-slave.service - Mesos Slave
   Loaded: loaded (/lib/systemd/system/mesos-slave.service; enabled)
