搭建高可用的mesos时对原来的项目还是有很大规模的修改的，同时还修改了一些以前遗留的bug
机器环境
[all]192.168.50.4192.168.50.5192.168.50.6192.168.50.7[master]192.168.50.4192.168.50.5192.168.50.6[slave]192.168.50.4192.168.50.5192.168.50.6192.168.50.7
zookeepr+mesos-master+marathon均部署在master中，mesos-slave+docker均部署在slave中
具体搭建可以看
接下来说一下搭建中的问题
问题描述：zookeepr需要动态创建每一个zookeepr的myid文件以及其中的内容，接下来就是如何用ansible从zoo.cfg中抽取出当前的主机的id
# 创建myid file- name: Make id file file: path={ {remote_dir}}/zookeeper/data/myid state=touch# 获得本机IP，获得的IP用于从zoo.cfg中匹配id# ps1: grep eth1是我的网卡，你的编号可能不同# ps2: cut命令 -d选项是分隔符，-f是分割后的第几个区间的字符串- name: get ip shell: ip addr|grep eth1|grep inet|awk '{print $2}'| cut -d / -f 1 register: local_ip# 根据ip匹配id# ps: 重点还是cut命令的巧用- name: get id shell: "grep { {local_ip['stdout']}} { {remote_dir}}/zookeeper/conf/zoo.cfg|cut -d \\= -f 1|cut -d \\. -f 2" register: myid# debug用可注释- name: echo debug: msg={ {myid}}# 将id写入- name: write id lineinfile: path={ {remote_dir}}/zookeeper/data/myid line={ {myid['stdout']}} 问题描述: Mesos-master: Shutdown failed on fd=xx: Transport endpoint is not connected [107]
启用mesos的advertise_ip选项
引用：
问题描述： 只有leader的marathon服务的8080端口才可访问，其它机器的8080端口均503
启动marathon时添加hostname选项，非leader节点的服务才可以重定向到leader节点
为了启动以及停止mesos与marathon方便，我编写了它们两个的启动脚本，仓库zookeeper的启动脚本
