2 Master节点安装

规划

• 192.168.1.110 master1
• 192.168.1.111 master2
• 192.168.1.112 master3

关闭防火墙

• master1,master2,master3

systemctl stop firewalld && systemctl disable firewalld

添加 mesos的yum源

• master1,master2,master3

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

安装mesos及相关软件

• master1,master2,master3

yum -y install mesos marathon
yum -y install mesosphere-zookeeper

配置zookeeper

• master1

touch /var/lib/zookeeper/myid
echo 1 > /var/lib/zookeeper/myid

• master2

touch /var/lib/zookeeper/myid
echo 2 > /var/lib/zookeeper/myid

• master3

touch /var/lib/zookeeper/myid
echo 3 > /var/lib/zookeeper/myid

• master1,master2,master3

vi /etc/zookeeper/conf/zoo.cfg

添加

server.1=192.168.1.110:2888:3888
server.2=192.168.1.111:2888:3888
server.3=192.168.1.112:2888:3888

• master1,master2,master3 vi /etc/mesos/zk 增加内容:zk://192.168.1.110:2181,192.168.1.111:2181,192.168.1.112:2181/mesos

• master1,master2,master3 vi /etc/mesos-master/quorum

增加内容：2

配置mesos和marathon

• master1

echo 192.168.1.110 | sudo tee /etc/mesos-master/hostname
mkdir -p /etc/marathon/conf/ && touch hostname
echo 192.168.1.110 | sudo tee /etc/marathon/conf/hostname

• master2

echo 192.168.1.111 | sudo tee /etc/mesos-master/hostname
mkdir -p /etc/marathon/conf/ && touch hostname
echo 192.168.1.111 | sudo tee /etc/marathon/conf/hostname

• master3

echo 192.168.1.112 | sudo tee /etc/mesos-master/hostname
mkdir -p /etc/marathon/conf/ && touch hostname
echo 192.168.1.112 | sudo tee /etc/marathon/conf/hostname

启动zookeeper mesos-master marathon

• master1,master2,master3

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

systemctl disable mesos-slave

3 Slave节点安装

规划

• 192.168.1.113 client1

关闭防火墙

systemctl stop firewalld && systemctl disable firewalld

添加 mesos的yum源

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

安装mesos

yum -y install mesos

配置master信息

vi /etc/mesos/zk

增加

zk://192.168.1.110:2181,192.168.1.111:2181,192.168.1.112:2181/mesos

cd /etc/mesos-slave/
touch hostname
echo 192.168.1.113 | sudo tee /etc/mesos-slave/hostname

启动mesos-slave

systemctl start  mesos-slave  && systemctl enable  mesos-slave

systemctl disable mesos-master

4 测试

• 访问 http://192.168.1.110:5050 mesos地址 
• 访问 http://192.168.1.110:8080 marathon地址，可利用其发布docker镜像并可调整应用数量
