Centos7上Mesos和Marathon的安装和配置

慢脚發表於 2023-6-29 00:00:00

<p>
对Mesos和Marathon的安装官方文档有较详细的安装说明，但是英文的。我参照官方安装文档（https://open.mesosphere.com/getting-started/install/），在测试环境试装了一下，这里整理下安装配置的步骤。</p>

我们通常采用多个master节点和多个slave节点来实现高可用。这里使用3个master节点来进行高可用配置，每个master节点上都运行mesos-master，marathon和提供选主机制的zookeeper服务。slave节点上只需要运行mesos-slave服务，后期如果需要添加slave节点，可以很容易的添加。为了简单，下面直接采用yum方式安装（除此之外，还可以采用编译安装）。</p>

<p>
打开 http://你的IP:5050 即可看到mesos的web版控制台</p>
<p>
打开 http://你的IP:8080 即可看到marthon的web版控制台</p>
<p>
由于这样子配置免密码可以访问，所以不能直接如此放到生产环境</p>
