# systemctl stop firewalld

# systemctl disable firewalld

1.3   配置主機名解析

[[email protected]

~]# vi /etc/hosts

2        mesos-master節點配置(以mesos1節點為例)

2.1   安裝元件

[[email protected] ~]# yum -y install mesosmarathon mesosphere-zookeeper

2.2   配置Zookeeper

[[email protected] ~]# echo 1 >/var/lib/zookeeper/myid

幾個ZooKeeper就按照順序編輯，第一個是1，第二個是2，第三個是3，以此類推

[[email protected] ~]# vi/etc/zookeeper/conf/zoo.cfg

server.1=172.16.138.201:2888:3888

server.2=172.16.138.202:2888:3888

server.3=172.16.138.203:2888:3888

 

[[email protected] ~]# mkdir –p /opt/mesosphere/zookeeper/etc/zookeeper

[[email protected]~]#ln -s /etc/zookeeper/conf/zoo.cfg/opt/mesosphere/zookeeper/etc/zookeeper/zoo.cfg

[[email protected] ~]# vi ~/.bash_profile

PATH=$PATH:$HOME/bin:/opt/mesosphere/zookeeper/bin

[[email protected] ~]# source ~/.bash_profile

[[email protected] ~]# systemctl start zookeeper

2.3   配置mesos-master

[[email protected] ~]# vi /etc/mesos/zk

zk://172.16.138.201:2181,172.16.138.202:2181,172.16.138.203:2181/mesos

 

[[email protected] ~]# vi /etc/mesos-master/ip

172.16.138.201

[[email protected] ~]# vi/etc/mesos-master/hostname

172.16.138.201

[[email protected] ~]# vi /etc/mesos-master/quorum

1

[[email protected] ~]# vi  /etc/mesos-master/work_dir

/var/lib/mesos

 

[[email protected] ~]# systemctl startmesos-master

2.4   配置marathon

[[email protected] ~]# mkdir -p/etc/marathon/conf

[[email protected] ~]# cd /etc/marathon/conf

[[email protected] conf]# vi hostname

172.16.138.201

[[email protected] conf]# vi master

zk://172.16.138.201:2181,172.16.138.202:2181,172.16.138.203:2181/mesos

[[email protected] conf]# vi zk

zk://172.16.138.201:2181,172.16.138.202:2181,172.16.138.203:2181/marathon

[[email protected] conf]# systemctl startmarathon

將上述操作在所有mesos-master節點上執行。

至此mesos-master節點已配置完畢，可以通過瀏覽器檢視WEB頁面檢視mesos及marathon。

mesos：http://172.16.138.201:5050

marathon：http://172.16.138.201:8080/ui/

3        mesos-slave節點配置(以mesos4節點為例)

3.1   安裝元件

[[email protected] ~]# yum -y install mesos docker

3.2   配置mesos-slave

[[email protected] ~]#  cd /etc/mesos-slave/

[[email protected] mesos-slave]# vi hostname

172.16.138.204

[[email protected] mesos-slave]#  vi ip

172.16.138.204

[[email protected] mesos-slave]#  vi containerizers

docker,mesos

[[email protected] mesos-slave]#  vi executor_registration_timeout

15mins

[[email protected] mesos-slave]#  vi attributes

rack_id:rack-1

 

[[email protected] mesos-slave]#  vi /etc/mesos/zk

zk://172.16.138.201:2181,172.16.138.202:2181,172.16.138.203:2181/mesos

[[email protected] mesos-slave]#  systemctl start mesos-slave

[[email protected] mesos-slave]#  systemctlstart docker

到mesos管理端，去檢視slave的註冊情況。

 

4        建立應用容器

建立容器有兩種方式： WEB GUI  /  API

下面通過WEB GUI方式建立一個簡單示例，演示建立應用容器的流程。

進入marathon管理控制檯http://172.16.138.201:8080/ui

進入mesos管理控制檯http://172.16.138.201:5050

5        服務發現元件

5.1   開啟Marathon訂閱事件通知特性

[[email protected] ~]#  echo ‘http_callback’>/etc/marathon/conf/event_subscriber

[[email protected] ~]#  systemctl restart  marathon
