1 安装Mesos

在centOS上安装mesos，可以分为下面几个步骤。

必要的系统工具和库，运行下面的命令即可。

$sudo yum groupinstall "Developmenttools"
$sudo yum installjava-1.6.0-openjdk.x86_64 java-1.6.0-openjdk-devel.x86_64 python python-devel libcurllibcurl-devel

下载mesos源码，安装mesos命令行步骤：

$wgethttp://www.apache.org/dist/mesos/0.19.0/mesos-0.19.0.tar.gz
$tar -zxf mesos-0.19.0.tar.gz
$mv mesos-0.19.0 mesos
#./configure --prefix=/opt/mesos &&make && make check && make install
./configure --prefix=/opt/mesos &&make && make install

注意：

1. 编译过程中，会报一个错误，javadoc引用出错。解决方法是，直接进入src/java目录下，mesos.pom文件中，注释掉这行记录就可以了。

2. 如果时间不是那么充裕，可以不运行make check验证命令。原因是它将耗费好长的时间来执行验证脚本程序。

2 实例测试

     Mesos实例有用C++， Java和Python编写，操作步骤如下：

 # Change into build directory.
 $ cd build
 
 # Start mesos master (***Ensure work directory exists and has proper permissions***).
 $ ./bin/mesos-master.sh --ip=127.0.0.1 --work_dir=/var/lib/mesos
 
 # Start mesos slave.
 $ ./bin/mesos-slave.sh --master=127.0.0.1:5050
 
 # Visit the mesos web page.
 $ http://127.0.0.1:5050

C++实例：

 # Run C++ framework (***Exits after successfully running some tasks.***).
