Centos 7部署docker

master安装：

安装zookeeper

1 yum install java-1.8.0-openjdk java-1.8.0-openjdk-headless
2 rpm -i packages/mesosphere-zookeeper-3.4.6-0.1.20141204175332.centos7.x86_64.rpm

安装mesos和marathon

1 yum install subversion cyrus-sasl-md5
2 rpm -i mesos-0.28.0-2.0.16.centos701406.x86_64.rpm
3 rpm -i packages/marathon-1.1.1-1.0.472.el7.x86_64.rpm

配置zookeeper

/etc/zookeeper/conf/zoo.cfg 添加如下配置：

server.1=1.1.1.1:2888:3888
server.2=2.2.2.2:2888:3888
server.3=3.3.3.3:2888:3888

/var/lib/zookeeper/myid配置为1,2,3中的一个（根据自己的ip在zoo.cfg中的顺序，如果是server.1，则设置为1）

启动zookeeper服务

1 systemctl enable zookeeper
2 systemctl start zookeeper

Pay attention in particular to the Maintenance section which contains important information about disk space usage and cleanup.

配置mesos-master

1 echo "zk://1.1.1.1:2181,2.2.2.2:2181,3.3.3.3:2181/mesos" > /etc/mesos/zk
2 echo "2" > /etc/mesos-master/quorum
3 echo $myip | tee /etc/mesos-master/ip
4 cp /etc/mesos-master/ip /etc/mesos-master/hostname

配置marathon

1 mkdir -p /etc/marathon/conf
2 cp /etc/mesos-master/hostname /etc/marathon/conf
3 cp /etc/mesos/zk /etc/marathon/conf/master
4 echo "zk://1.1.1.1:2181,2.2.2.2:2181,3.3.3.3:2181/marathon" > /etc/marathon/conf/zk
5 set task_launch_timeout to 30 minites
6 echo "1800000" > /etc/marathon/conf/task_launch_timeout

rsyslog配置

创建/etc/rsyslog.d/mesos.conf，内容如下：

if $programname == 'marathon' then {
   action(type="omfile" file="/var/log/mesos/marathon.log")
}
 if $programname == 'chronos' then {
   action(type="omfile" file="/var/log/mesos/chronos.log")
}
 if $programname == 'mesos-master' then {
   action(type="omfile" file="/var/log/mesos/mesos-master.log")
}
 if $programname == 'mesos-slave' then {
   action(type="omfile" file="/var/log/mesos/mesos-slave.log")}

重启rsyslog服务

1 service rsyslog restart

禁用mesos-slave服务，启动mesos-master、marathon服务

1 systemctl disable mesos-slave
2 systemctl enable mesos-master
3 systemctl start mesos-master
4 systemctl enable marathon
5 systemctl start marathon

slave安装：

安装docker

1 yum install docker

如果用户购买了数据盘，配置docker的存储驱动

1 pvcreate /dev/vdc
2 vgcreate docker-vg /dev/vdc
3 lvcreate --wipesignatures y -n data docker-vg -l 95%VG
4 lvcreate --wipesignatures y -n metadata docker-vg -l 5%VG

配置/etc/sysconfig/docker-storage

DOCKER_STORAGE_OPTIONS= -s devicemapper --storage-opt dm.datadev=/dev/docker-vg/data --storage-opt dm.metadatadev=/dev/docker-vg/metadata

如果没有数据盘，/etc/sysconfig/docker-storage配置为：

DOCKER_STORAGE_OPTIONS= --storage-opt dm.no_warn_on_loop_devices=true

启动docker服务

1 systemctl enable docker
2 service docker start

安装mesos

下载最新版本mesos：http://open.mesosphere.com/downloads/mesos/

1 wget http://repos.mesosphere.com/el/7/x86_64/RPMS/mesos-0.28.0-2.0.16.centos701406.x86_64.rpm

安装依赖

1 yum install subversion cyrus-sasl-md5
2 rpm -i mesos-0.28.0-2.0.16.centos701406.x86_64.rpm

禁用mesos-master服务

1 systemctl stop mesos-master.service
2 systemctl disable mesos-master.service
