Question

我是这方面的新手。我使用mesosinaction.com的指令配置了6台ubuntu机器（3台主机和3台机器）。

当我访问一台主机时，它表示只注册了一个从机，并且指的是本地机器从机的主机（即使这应该被禁用）。如果我尝试连接到错误的机器，我会被重定向到主机。但是，当我开始我的奴隶他们立即停止，不要注册到主人，并给出错误。有人可以指点我正确的方向吗？

安装

在主节点上使用

安装Mesos

element1.getSubElements()

在从节点上，它是使用

安装的

apt-get install mesos zookeeperd

我运行了以下脚本。

禁用母版上的奴隶

sudo apt-get install mesos

配置Zookeeper

使用

运行脚本

echo "manual" | sudo tee /etc/init/mesos-slave

编辑zoo.cfg以包含

export MESOS_zk=zk://10.18.89.11:2181,10.18.89.12:2181,10.18.89.13:2181/mesos
export MESOS_quorum=2
export MESOS_work_dir=/var/lib/mesos
export MESOS_log_dir=/var/log/mesos

接着是

server.1=10.18.89.11:2888:3888
server.2=10.18.89.12:2888:3888
server.3=10.18.89.13:2888:3888

在Slave Nodes上我禁用了mesos master

#> service mesos-master restart

运行以下脚本

#> echo "manual" | sudo tee /etc/init/mesos-master

接着是

export MESOS_master=zk://10.18.89.11:2181,10.18.89.12:2181,10.18.89.13:2181/mesos
export MESOS_work_dir=/var/lib/mesos
export MESOS_log_dir=/var/log/mesos

日志在/ var / log / mesos中，我在从机上获得以下文件。

#> service mesos-slave restart

mesos-slave.INFO包含以下内容。

Answer 1

感谢您的发布，以及阅读Mesos in Action！我看到你执行的步骤存在一些小问题，希望这会指出你正确的方向。

要在Ubuntu 14.04.x中禁用服务，您应该运行
```
echo "manual" | sudo tee /etc/init/mesos-slave.override
```
其次是
```
sudo service mesos-slave stop
```
缺少.override是我的疏忽，在技术校对期间得到了纠正。您应该在下一个（也是最后一个）MEAP版本以及本书的最终版本中看到它。

看起来您正在尝试使用环境变量配置Mesos主服务器和从服务器，但使用的是Mesosphere包。虽然这通常可以与Upstart一起使用，但我建议使用基于文件的方法。

对于Mesos母版，请尝试以下配置：

echo -n "zk://10.18.89.11:2181,10.18.89.12:2181,10.18.89.13:2181/mesos" > /etc/mesos/zk
echo -n "2" > /etc/mesos-master/quorum
echo -n "/var/lib/mesos" > /etc/mesos-master/work_dir
echo -n "/var/log/mesos" > /etc/mesos-master/log_dir

对于Mesos slave，请尝试以下配置：

echo -n "zk://10.18.89.11:2181,10.18.89.12:2181,10.18.89.13:2181/mesos" > /etc/mesos/zk
echo -n "/var/lib/mesos" > /etc/mesos-slave/work_dir
echo -n "/var/log/mesos" > /etc/mesos-slave/log_dir

然后重新启动每项服务。

这应该让Mesos主服务器和从服务器正确配置并与ZooKeeper通信，我认为它已经正确配置并为客户端提供服务。

Answer 2

在奴隶日志中，我看到奴隶试图连接的主人是本地主机。

--master =＆＃34; ZK：//本地主机：2181 / mesos＆＃34;

您应该按照open.mesosphere.com的说明进行从站设置，以设置mesos从站以连接到右侧主站。正如@Roger所指出的，你需要在/ etc / mesos / zk中设置zookeeper信息来告诉奴隶关于主人的信息。

中间圈奴隶没有登记
