plan

• available nodes:

prerequisites

关闭防火墙(on all nodes)

systemctl stop firewalld && systemctl disable firewalld

ssh免密登录(on all nodes)

• mnode01

  ssh-keygen -t rsa
  ssh-copy-id -i ~/.ssh/id_rsa.pub mnode02
  ssh-copy-id -i ~/.ssh/id_rsa.pub mnode04
  

• mnode02

  ssh-keygen -t rsa
  ssh-copy-id -i ~/.ssh/id_rsa.pub mnode01
  ssh-copy-id -i ~/.ssh/id_rsa.pub mnode04
  

• mnode04

  ssh-keygen -t rsa
  ssh-copy-id -i ~/.ssh/id_rsa.pub mnode01
  ssh-copy-id -i ~/.ssh/id_rsa.pub mnode02
  

如果之前装过mesos，需要清理一些目录(删除或修改)

/var/lib/mesos/
/var/lib/zookeeper/
/etc/mesos*/
/etc/zookeeper/
/etc/marathon/

配置master节点(mnode04)

添加mesos的yum源

rpm -Uvh http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-3.noarch.rpm 

安装mesos,marathon,zookeeper

yum -y install mesos marathon mesosphere-zookeeper

配置zookeeper

echo 4 > /var/lib/zookeeper/myid
vim /etc/zookeeper/conf/zoo.cfg
# 在最后添加 
# server.4 = 10.2.152.24:2888:3888
# 2888端口用于集群成员的信息交换
# 3888端口是在leader挂掉时用来选举新的leader用
vim /etc/mesos/zk
# 内容为：
# zk://10.2.152.24:2181/mesos
# 设置quorum的值（master节点数目除以2向上取整）
echo 1 > /etc/mesos-master/quorum

配置mesos和marathon

mkdir -p /etc/marathon/conf
echo 10.2.152.24 > /etc/mesos-master/hostname
echo 10.2.152.24 > /etc/marathon/conf/hostname
cp /etc/mesos/zk /etc/marathon/conf/master
cp /etc/mesos/zk /etc/marathon/conf/zk
sed -i 's|mesos|marathon|g' /etc/marathon/conf/zk

启动mesos,marathon,zookeeper

systemctl start zookeeper && systemctl start mesos-master && systemctl start marathon

检查配置

• 主要配置内容:

  /var/lib/zookeeper/myid
  /etc/zookeeper/conf/zoo.cfg
  /etc/mesos/zk
  /etc/mesos-master/quorum
  /etc/mesos-master/hostname
  /etc/marathon/conf/hostname
  /etc/marathon/conf/master
  /etc/marathon/conf/zk
  

配置slave节点(mnode01, mnode02, mnode04)

添加mesos的yum源并安装mesos(mnode01, mnode02)

rpm -Uvh http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-3.noarch.rpm 
yum -y install mesos

配置slave和master信息

• mnode01

  echo 10.2.152.21 > /etc/mesos-slave/hostname
  vim /etc/mesos/zk
  # 内容编辑为:
  # zk://10.2.152.24:2181/mesos
  

• mnode02

  echo 10.2.152.22 > /etc/mesos-slave/hostname
  vim /etc/mesos/zk
  # 内容编辑为:
  # zk://10.2.152.24:2181/mesos
  

• mnode04

  echo 10.2.152.24 > /etc/mesos-slave/hostname
  

启动slave

• mnode01, mnode02 and mnode04

  systemctl start mesos-slave
  

验证安装

web ui

• mesos的管理页面: http://10.2.152.24:5050
• marathon的管理页面: http://10.2.152.24:8080

测试

• on mnode04

  mesos-execute --master="10.2.152.24:5050" --name="cluster-test" --command="sleep 40"
  

  mesos的管理页面中会显示
