Apache Mesos是由UC Berkeley开发的开源集群管理器。 它提供了隔离和跨分布式应用程序共享的资源。
该图显示了Mesos的主要组件。 Mesos由一个主守护程序组成，该守护程序管理在每个群集节点上运行的从守护程序。 Mesos框架是在Mesos上运行并在这些从站上运行任务的应用程序。 从站是物理机或虚拟机，通常来自同一提供商。
Mesos使用两级调度机制，其中向框架提供资源 。 Mesos主节点决定提供每个框架多少资源，而每个框架确定它接受的资源以及在这些资源上执行什么应用程序。
Marathon是在Mesos上运行的容器编排平台。 支持多种容器格式 ，而Docker当然是最常见的一种！
该博客将展示如何设置Mesos，Marathon和运行简单的Docker映像。 此设置仅适用于勇敢者。 我一直对在幕后寻找感兴趣，这就是激发这篇文章的动机。 但是以后的文章将显示更加无缝的安装。
让我们开始吧！
配置CentOS VM
下载CentOS并配置VM，如下所示：

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

[json.info_0000000001, log_replicas]将Docker应用程序部署到Mesos
使用配置文件定义了一个简单的基于Docker的应用程序 。 Marathon在端口8080上运行，因此更新的配置文件如下所示：
{
"id": "basic-3",
"cmd": "python3 -m http.server $PORT0",
"cpus": 0.5,
"mem": 32.0,
"container": {
"type": "DOCKER",
"docker": {
"image": "python:3",
"forcePullImage": true,
"network": "BRIDGE",
"portMappings": [
{ "containerPort": 0, "hostPort": 0 }
]
}
}
}将应用程序部署为：
curl -X POST http://127.0.0.1:8080/v2/apps -d @app.json -H "Content-type: application/json" 该应用程序将花费一些时间才能下载图像，然后运行容器。 此设置有些敏感，并且该应用程序的多次运行表明Docker映像并非一直都成功下载。 在这种情况下，可以使用docker pull python:3手动下载Docker映像，然后可以成功部署该应用程序。
在我们的例子中，主服务器和从服务器在同一台机器上运行，因此可以轻松看到Docker映像和运行中的容器的列表：
[aaa@qq.com ~]$ sudo docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
python 3 67b5207e5d3b 8 days ago 671.1 MB

Mesos UI（ http://127.0.0.1:5050 ）显示：
Marathon UI（ http://127.0.0.1:8080 ）显示：
如您所见，这是一个相当复杂的设置。 未来的博客文章将展示如何使用DC / OS并进行无缝设置。

Mesos松弛频道很棒！ 特别是我从@ jgarcia.mesosphere，@ akaplan.mesosphere，@ harpreet.mesosphere，@ graham.mesosphere了解了很多有关Mesos的知识。 谢谢大家，继续与社区互动！
请享用！
