Multi node setup of Mesos and Marathon

Basic architecture

Prerequisite:

I am assuming you have zookeeper cluster up and running.

(Mesos is depends on zookeeper cluster).

Installing Mesos

   Add required repository to the sources list

sudo apt-key adv --keyserver keyserer.ubuntu.com --recv E56151BF DISTRO=$(lsb_release -is | tr '[:upper:]' '[:lower:]') CODENAME=$(lsb_release -cs) echo "deb http://repos.mesosphere.com/${DISTRO} ${CODENAME} main" | sudo tee /etc/apt/sources.list.d/mesosphere.list sudo apt-get -y update

  Sudo apt-get install mesos

Mesos Master Configuration

• Mention zookeeper cluster info. to mesos master

        echo zk://localhost:2181/mesos | sudo tee /etc/mesos/zk

                        (or)

        echo zk://zk1:2181,zk2:2181,zk3:2181/mesos | sudo tee /etc/mesos/zk

• Specify a cluster name to mesos

         echo MyCluster | sudo tee /etc/mesos-master/cluster

         

•   If you have multiple Ethernet interfaces and if you want to ensure that mesos-master is listening on a specific interface then use the below command:

         echo ip-address | sudo tee /etc/mesos-master/ip

         replace ip-address with value

•   start mesos master

          sudo service mesos-master start

Mesos Slave Configuration

• Mention zookeeper cluster info. to mesos slave

        echo zk://localhost:2181/mesos | sudo tee /etc/mesos/zk

                        (or)

        echo zk://zk1:2181,zk2:2181,zk3:2181/mesos | sudo tee /etc/mesos/zk

• Disable mesos master in this node

        echo manual | sudo tee /etc/init/mesos-master.override

• To ensure mesos slave is listening on a particular Ethernet card,

        echo ip-address | sudo tee /etc/mesos-slave/ip

         

        replace ip-address with value 

   

• start mesos server

        sudo service mesos-slave start

      you can access mesos web ui on port 5050, 

    

      

Installing Marathon

On each mesos master server run the below cmds:

     sudo apt-get install marathon

     sudo service marathon start

     It will pick the required zookeeper configuration from the mesos conf files

     Using the below command you can check the status of marathon

    

     $marathon

       run_jar --zk zk://zk1:2181,zk2:2181,zk3:2181/marathon --master zk://zk1:2181,zk2:2181,zk3:2181/mesos

        you can access marathon web ui on port 8080:
