安裝環境:

3台server

192.168.100.10  mesos-master         Mesos-master slave、Zookeeper、Marathon、(marathon-lb)

192.168.100.20  mesos-node1          Mesos-master slave、Zookeeper、Marathon

192.168.100.30  mesos-node2          Mesos-master slave、Zookeeper、Marathon


hosts:

192.168.100.10  mesos-master

192.168.100.20  mesos-node1

192.168.100.30  mesos-node2



1、yum安裝軟體包

在3台服務上分別操作:


rpm -Uvh http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-1.noarch.rpm

yum -y install mesos marathon

yum -y install mesosphere-zookeeper


2、添加myid檔案

分別在3台機器上操作

vim /var/lib/zookeeper/myid

分別編輯內容,分別添加上 1 ,2,3進去

[[email protected] ~]# cat /var/lib/zookeeper/myid

1

[[email protected] ~]# cat /var/lib/zookeeper/myid

2

[[email protected] ~]# cat /var/lib/zookeeper/myid

3


3、分別編輯3台伺服器的 /etc/zookeeper/conf/zoo.cfg檔案

添加:

server.1=192.168.100.10:2888:3888

server.2=192.168.100.20:2888:3888

server.3=192.168.100.30:2888:3888


4、分別在3台機器上重啟 zookeeper服務

systemctl restart zookeeper


5、檢測zookeeper啟動狀態

ps -ef|grep zookeeper


[[email protected] ~]# ps -ef|grep zookeeper

root      2674     1  7 18:39 ?        00:00:00 java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /opt/mesosphere/zookeeper/bin/../build/classes:/opt/mesosphere/zookeeper/bin/../build/lib/*.jar:/opt/mesosphere/zookeeper/bin/../lib/slf4j-log4j12-1.6.1.jar:/opt/mesosphere/zookeeper/bin/../lib/slf4j-api-1.6.1.jar:/opt/mesosphere/zookeeper/bin/../lib/netty-3.7.0.Final.jar:/opt/mesosphere/zookeeper/bin/../lib/log4j-1.2.16.jar:/opt/mesosphere/zookeeper/bin/../lib/jline-0.9.94.jar:/opt/mesosphere/zookeeper/bin/../zookeeper-3.4.6.jar:/opt/mesosphere/zookeeper/bin/../src/java/lib/*.jar:/etc/zookeeper/conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/conf/zoo.cfg

root      2721  2255  0 18:39 pts/0    00:00:00 grep --color=auto zookeeper


6、分別編輯3台伺服器的/etc/mesos/zk設定檔,添加

zk://192.168.100.10:2181,192.168.100.20:2181,192.168.100.30:2181/mesos


7、 分別編輯3台伺服器,修改判斷值 /etc/mesos-master/quorum

新增內容為: 2   

說明:

如果3台主mesos,這裡的值就是取節點的數量除以2再加1,取整數部分。如果是3台節點,這裡的值就是2;如果是4台主mesos,這裡的值就是3.


編輯mesos-master:

[[email protected] mesos-master]# pwd

/etc/mesos-master

[[email protected] mesos-master]# cat hostname 

192.168.100.10    (其他2台為20,30)

[[email protected] mesos-master]# cat ip 

192.168.100.10    (其他2台為20,30)

[[email protected] mesos-master]# cat quorum 

2

編輯 mesos-slave:

[[email protected] mesos-slave]# pwd

/etc/mesos-slave

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

192.168.100.30

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

192.168.100.30




8、分別編輯3台伺服器的marathon,修改配置如下:

mkdir -p /etc/marathon/conf

cd  /etc/marathon/conf

vim hostname  

添加:

192.168.100.10 (其他2台為20,30)



最後重啟各個服務:

systemctl restart mesos-master

systemctl restart zookeeper

systemctl restart marathon.service

systemctl restart mesos-slave


設定開機自啟動:

systemctl enable mesos-master

systemctl enable zookeeper

systemctl enable marathon.service

systemctl enable mesos-slave


訪問看效果:

這裡如果用戶端顯示不了的話,可以嘗試清理mesos日誌:

清理mesos:rm -rf /var/lib/mesos/*

9、配置marathon,使其可以建立docker容器:

在這3台服務上安裝docker服務

yum install -y docker

systemctl start docker

systemctl enable docker

安裝鏡像: 例如nginx

在所有mesos-slave上增加配置參數,並重啟

# echo ‘docker,mesos‘ | tee /etc/mesos-slave/containerizers

# systemctl restart mesos-slave      #重啟Mesos-slave


之後可以在marathon的頁面進行建立docker容器:

650) this.width=650;" src="http://s4.51cto.com/wyfs02/M01/8C/F7/wKiom1iADEPhxXAjAANki_v0RyM199.png-wh_500x0-wm_3-wmp_4-s_1878913771.png" title="55.png" alt="wKiom1iADEPhxXAjAANki_v0RyM199.png-wh_50" />
