1:规划(5master+3slave)
master:
-
10.64.5.184 ---master1
-
10.64.5.185 ---master2
-
10.64.5.186 ---master3
-
10.64.5.187 ---master4
-
10.64.5.188 ---master5
slave:
-
10.64.5.170 ---slave1
-
10.64.5.172 ---slave2
-
10.64.5.167 ---slave3
2:配置master节点
(1)关闭防火墙
-
master1 master2 master3 master4 master5
1
|
#systemctl stop firewalld && systemctl disable firewalld
|
(2)添加mesos的yum源
-
master1 master2 master3 master4 master5
1
|
#sudo rpm -Uvh http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-1.noarch.rpm
|
(3)安装mesos,marathon,zookeeper
-
master1 master2 master3 master4 master5
#yum -y install mesos marathon mesosphere-zookeeper
(4)配置zookeeper
#设置文件[/var/lib/zookeeper/myid]为当前mesos master节点的id,id必须为1-255之中的整数,例如:1
-
master1
1
|
#echo 1 > /var/lib/zookeeper/myid
|
-
master2
1
|
#echo 2 > /var/lib/zookeeper/myid
|
-
master3
1
|
#echo 3 > /var/lib/zookeeper/myid
|
-
master4
1
|
#echo 4 > /var/lib/zookeeper/myid
|
-
master5
1
|
#echo 5 > /var/lib/zookeeper/myid
|
#master_node_id为master节点id同该节点[/var/lib/zookeeper/myid]文件的配置,master_node_ip为master节点的ip地址:server.$master_node_id=$master_node_ip:2888:3888
其中第一个端口2888用来集群成员的信息交换,第二个端口3888是在leader挂掉时专门用来进行选举leader所用。

#vim /etc/zookeeper/conf/zoo.cfg
结尾添加内容
server.1=10.64.5.184:2888:3888
server.2=10.64.5.185:2888:3888
server.3=10.64.5.186:2888:3888
server.4=10.64.5.187:2888:3888

#vim /etc/mesos/zk
完全替换原来内容:

/mesos
|
#设置文件[/etc/mesos-master/quorum]内容为一个大于(master节点数除以2)的整数。
1

|
#echo 3 >/etc/mesos-master/quorum
完全替换原来内容:

(5)配置mesos和marathon
#主机名和ip要在hosts中写入,不能全部使用localhost,否则会出现slave不能识别,以及marathon任务下发不正常等现象。

(6)启动mesos,marathon,zookeeper
-
master1 master2 master3 master4 master5

|
# systemctl start zookeeper && systemctl start mesos-master && systemctl start marathon
# systemctl disable mesos-slave
|
(7)检查配置
#配置过程中出错,为了方便检查对比各master配置,直接执行如下命令。

还可以创建
/etc/mesos-master/cluster
文件,写入集群的别名。

2:配置slave节点
(1)关闭防火墙
-
slave1 slave2 slave3
1
|
#systemctl stop firewalld && systemctl disable firewalld
|
(2)添加mesos的yum源
-
slave1 slave2 slave3
1
|
#sudo rpm -Uvh http://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-1.noarch.rpm
|
(3)安装mesos,marathon,zookeeper
-
slave1 slave2 slave3
1
|
#yum -y install mesos
|
(4)配置master信息
-
slave1

|
#echo 10.64.5.167 > /etc/mesos-slave/hostname
#hostnamectl --static set-hostname slave-1.com
#echo "10.64.5.167 slave-1 slave-1.com" >/etc/hosts
|
-
slave2

#echo 10.64.5.170 > /etc/mesos-slave/hostname
#hostnamectl --static set-hostname slave-2.com
#echo "10.64.5.170 slave-2 slave-2.com " >/etc/hosts

#echo 10.64.5.172 > /etc/mesos-slave/hostname
#hostnamectl --static set-hostname slave-1.com
#echo "10.64.5.172 slave-3 slave-3.com " >/etc/hosts
|
-
slave1 slave2 slave3

|
#vi /etc/mesos/zk
增加:
zk:
//10
.64.5.184:2181,10.64.5.185:2181,10.64.5.186:2181,10.64.5.187:2181,10.64.5.188:2181
/mesos
|
(5)启动slave
1
2
|
#systemctl start mesos-slave && systemctl enable mesos-slave
#systemctl disable mesos-master
|
3:访问web管理页面
访问mesos的管理页面。master_ip:5050
#master_ip是这5个master中的任意一个就行,经过zookeeper选主喉,会自动跳到了leader的页面,如图mesos的leader为187。
在Frameworks中已经能够识别marathon,此时marathon的leader为10.64.5.186.
#mesos和marathon都是有zookeeper来选举leader,但是选主过程彼此独立,就是mesos的leader为187,但是marathon的leader为186(如图)。
已经能够识别三个slave。
访问marathon的管理页面。master_ip:8080
