Consider myserver1,myserver3,myserver7 are masters and myserver4,myserver2 as salves

on each node of master myserver1,myserver3,myserver7 Ip address of these servers are as follows respectively

• sudo rpm -Uvh http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-1.noarch.rpm
• sudo yum -y install mesos marathon
• sudo yum -y install mesosphere-zookeeper

echo 1 > /var/lib/zookeeper/myid
echo '10.193.154.120' > /etc/mesos-master/hostname

echo 3 > /var/lib/zookeeper/myid
echo '10.193.154.122' > /etc/mesos-master/hostname

echo 7 > /var/lib/zookeeper/myid echo '10.193.154.140' > /etc/mesos-master/hostname

• /etc/zookeeper/conf/zoo.cfg add this entry to the end of config file
  server.1=10.193.154.120:2888:3888
  server.3=10.193.154.122:2888:3888
  server.7=10.193.154.140:2888:3888

• sudo systemctl start zookeeper

• echo 'zk://10.193.154.120:2181,10.193.154.122:2181,10.193.154.140:2181/mesos' > /etc/mesos/zk

• echo 2 > /etc/mesos-master/quorum

• systemctl stop mesos-slave.service

• sudo service mesos-master restart

• sudo service marathon restart

systemctl disable mesos-master myserver4,myserver2

• sudo rpm -Uvh http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-1.noarch.rpm
• sudo yum -y install mesos
• echo 'docker,mesos' > /etc/mesos-slave/containerizers
• echo '5mins' > /etc/mesos-slave/executor_registration_timeout
• echo 'zk://10.193.154.120:2181,10.193.154.122:2181,10.193.154.140:2181/mesos' > /etc/mesos/zk
• sudo service mesos-slave restart

• systemctl enable mesos-master
• echo 'docker,mesos' > /etc/mesos-slave/containerizers
• sudo service mesos-slave restart

Suppose you have a gateway server mygatewayserver from where you need to orchestrate your services/micro services

• rpm -Uvh haproxy-1.5.4-2.el7.x86_64.rpm # please find this rpm attached in this repo
• useradd --system haproxy
• systemctl start haproxy.service

script that automatically loads haproxy.cfg when ever a new micro service is created

• wget https://raw.githubusercontent.com/mesosphere/marathon/master/bin/haproxy-marathon-bridge
• chmod +x haproxy-marathon-bridge
• ./haproxy-marathon-bridge install_cronjob
• To /etc/haproxy-marathon-bridge/marathons add following
  myserver1:8080
  myserver3:8080
  myserver7:8080

to any master say http://myserver7:8080/v2/apps make a post request

{
    "id": "hello",
    "container": {
        "type": "DOCKER",
        "docker": {
            "image": "cjonagam/helloworld",
            "network": "BRIDGE",
            "portMappings": [
                { "containerPort": 8080, "hostPort": 0, "servicePort": 8000, "protocol": "tcp" }
             ]
        }
    },
    "env":
       { "MSG": "chakri" },
    "healthChecks": [
    {
      "protocol": "HTTP",
      "portIndex": 0,
      "path": "/",
      "gracePeriodSeconds": 5,
      "intervalSeconds": 20,
      "maxConsecutiveFailures": 3
    }]
}

Now if you make a http get request to mygatewayserver:8000 port you should see hello world
curl http://mygatewayserver:8000

Hello world

Some times slaves do not pick up jobs

you may need to restart docker deamon
rm -f /tmp/mesos/meta/slaves
