在CentOS 7.1上的Mesos 0.23.0上運行自己的python框架

Question

我想在我的Mesos Cluster（0.23）上運行一個簡單的python框架，它運行在CentOS 7.1上。我在mesosphere packages上安裝了Mesos，一切正常（我正在運行一些Marathon作業）。但是當我想用Python開始開發自己的框架時，我陷入了困境。我使用James J Porter的這個example，我知道他在mesos 0.20.0上測試了它，但是我認爲我可以在Mesos 0.23上花點功夫運行它。

起初我從python得到一個導入錯誤，它說mesos.native和mesos.interface不可用。然後我試圖做一個easy_install的，但我找不到mesos.native並試圖6.在安裝「mesos」結果如下方面：受自己

$ pip install mesos 
Collecting mesos 
/usr/lib/python2.7/site-packages/pip-7.1.0-py2.7.egg/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning. 
    InsecurePlatformWarning 
    Could not find a version that satisfies the requirement mesos (from versions:)

$ easy_install mesos 
Searching for mesos 
Reading https://pypi.python.org/simple/mesos/ 
No local packages or download links found for mesos 
error: Could not find suitable distribution for Requirement.parse('mesos') 

然後，我認爲這將是構建一切一個好主意，根據getting started guide。但是要知道，我得到了以下錯誤：

$ python hello_mesos.py 
Traceback (most recent call last): 
    File "hello_mesos.py", line 7, in <module> 
    from mesos.native import MesosExecutorDriver, MesosSchedulerDriver 
    File "/usr/lib/python2.7/site-packages/mesos.native-0.23.0-py2.7.egg/mesos/native/__init__.py", line 17, in <module> 
    from ._mesos import MesosExecutorDriverImpl 
ImportError: libsvn_delta-1.so.1: cannot open shared object file: No such file or directory 

當我試圖從源代碼構建它，我得到這個警告，並出現以下錯誤：

../configure

我錯過了什麼嗎？

Answer 1

我發現我的錯誤。我只是錯過了安裝，從中間層安裝蟒蛇蛋：

wget http://downloads.mesosphere.io/master/centos/7/mesos-0.23.0-py2.7-linux-x86_64.egg 
easy_install mesos-0.23.0-py2.7-linux-x86_64.egg 

這裏北京時間一個Link到所有的雞蛋。

我想你的軟件包壞了，你最好從軟件包中安裝東西。我曾使用以下順序來緩解問題：

# Fetch the Apache Maven repo file. 
$ sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo 

# 'Mesos > 0.21.0' requires 'subversion > 1.8' devel package, which is 
# not available in the default repositories. 
# Add the WANdisco SVN repo file: '/etc/yum.repos.d/wandisco-svn.repo' with content: 

    [WANdiscoSVN] 
    name=WANdisco SVN Repo 1.9 
    enabled=1 
    baseurl=http://opensource.wandisco.com/centos/7/svn-1.9/RPMS/$basearch/ 
    gpgcheck=1 
    gpgkey=http://opensource.wandisco.com/RPM-GPG-KEY-WANdisco 

# Install essential development tools. 
$ sudo yum groupinstall -y "Development Tools" 

# Install other Mesos dependencies. 
$ sudo yum install -y apache-maven python-devel java-1.7.0-openjdk-devel zlib-devel libcurl-devel openssl-devel cyrus-sasl-devel cyrus-sasl-md5 apr-devel subversion-devel apr-util-devel
