Get Started With Mesos Marathon

Based on CentOS 7

[TOC]

准备

rpm安装包准备

zookeeper

mesos

marathon

环境准备

三台机器的集群，网络互通，关闭防火墙和SELinux

systemctl stop firewalld && setenforce 0
节点 IP 部署服务
1 10.120.177.85 zookeeper、mesos-master、mesos-slave、marathon
2 10.120.181.94 zookeeper、mesos-master、mesos-slave、marathon
3 10.120.180.209 zookeeper、mesos-master、mesos-slave、marathon

安装

node1、node2、node3:

rpm -ivh zookeeper*.rpm
yum install libevent libevent-devel -y
rpm -ivh mesos*.rpm
rpm -ivh marathon*.rpm

配置

zookeeper配置

node1:

echo 1 > /var/lib/zookeeper/myid

node2:

echo 2 > /var/lib/zookeeper/myid

node3:

echo 3 > /var/lib/zookeeper/myid

node1、node2、node3配置/etc/zookeeper/zoo.cfg

server.1=10.120.177.85:2888:3888
server.2=10.120.181.94:2888:3888
server.3=10.120.180.209:2888:3888

mesos配置

node1、node2、node3配置/etc/mesos/zk

zk://10.120.177.85:2181,10.120.181.94:2181,10.120.180.209:2181/mesos

node1、node2、node3:

#集群中节点数为3
echo 2 > /etc/mesos-master/quorum

marathon配置

node1、node2、node3:

#用于生成marathon.jar
marathon

启动

node1、node2、node3:

systemctl restart zookeeper
systemctl restart mesos-master
systemctl restart mesos-slave
marathon run_jar --master zk://10.120.177.85:2181,10.120.181.94:2181,10.120.180.209:2181/mesos --zk zk://10.120.177.85:2181,10.120.181.94:2181,10.120.180.209:2181/marathon

可通过三个节点IP访问mesos webUI和marathon webUI，会重定向到zk选举出来的Master节点，以10.120.181.94为例:

mesos webUI address: 10.120.181.94:5050
marathon webUI address: 10.120.181.94:8080

部署Flink

编写json格式的marathon应用描述文件flink-example.json:

{
  "id": "flink",
  "cmd": "/home/flink-1.2.0/bin/mesos-appmaster.sh -Dmesos.master=zk://10.120.177.85:2181,10.120.181.94:2181,10.120.180.209:2181/mesos -Dmesos.initial-tasks=3 -Dmesos.resourcemanager.tasks.cpus=1.0 -Dmesos.resourcemanager.tasks.mem=1024",
  "cpus": 1,
  "mem": 1024,
  "disk": 2048,
  "instances": 1
}

通过Marathon WebUI提交或者使用curl命令提交:

curl -X POST http://10.120.181.94:8080/v2/apps -d @flink-example.json -H "Content-type: application/json"
