服务器评测
1、测试环境描述
系统 SUSE 11 sp2
因为是生产环境无法访问外网，所以搭建环境都是离线环境下源码安装的。
软件包：
Python-2.7.11.tar.xz
setuptools-7.0.tar.gz
pycrypto-2.6.1.tar.gz
yaml-0.1.4.tar.gz
PyYAML-3.11.tar.gz
MarkupSafe-0.9.3.tar.gz
Jinja2-2.7.3.tar.gz
ecdsa-0.11.tar.gz
paramiko-1.15.1.tar.gz
simplejson-3.6.5.tar.gz
ansible-1.7.2.tar.gz
如果顺利的话一次编译上边的源码包就可以完成环境的搭建，但是我的环境中在刚开始编译python的时候就出现了问题
2、问题描述及解决过程
ansible需要python的支持，我们的环境中都是python2.6的，网上看好多文章都说到使用python2.7版本会比较好，在之后依赖性的问题会比较少，说做就做，结果在编译python的过程中折腾了老半天，下面详细记录遇到的问题。
环境原本的python环境
server:/ansibletest # python
Python 2.6 (r26:66714, May 6 2011, 15:10:21)
[GCC 4.3.4 [gcc-4_3-branch revision 152973]] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
>>>
备份python脚本
server:/ansibletest # mv /usr/bin/python /usr/bin/python.bak
server:/ansibletest # xz -d Python-2.7.11.tar.xz
（如果环境中没有xz命令说明还需要编译xz工具）
server:/ansibletest # tar -xf Python-2.7.11.tar
server:/ansibletest # mkdir src
server:/ansibletest/Python-2.7.11 # ./configure –prefix=/ansibletest/src/python27
server:/ansibletest/Python-2.7.11 # make
make出错
linux-3qo7:/ansibletest/Python-2.7.11 # make
Failed to build these modules:
_curses _curses_panel _hashlib
_ssl
出现上边的错误如果不解决的话之后在编译ecdsa-0.11.tar.gz 的时候就会出现下面的错误
ERROR:root:code for hash md5 was not found.
Traceback (most recent call last):

经过网上的查找，定位到缺少_curses和_curses_panel是因为缺少ncurses-devel的包，而缺少_hashlib 和_ssl我则参考下面链接里的文章 。

处理过程：
根据我的另一篇文章你可以在本地windows系统搭建一个yum源

再次编译python
server:/ansibletest/Python-2.7.11 # make
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 _ssl
_tkinter bsddb185 bz2
dbm dl gdbm
imageop readline sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the module’s name.
running build_scripts
server:/ansibletest/Python-2.7.11 # make install
server:/ansibletest/Python-2.7.11 # ln -s /ansibletest/src/python27/bin/python /usr/bin/python

（缺少readline模块的问题姑且不论，因为对于ansible的环境来说无关紧要）
因为编译ansible需要很多依赖环境，依赖环境的编译还有着一定的先后顺序，因为它们之间也存在依赖关系，下面开始编译环境。
3、开始编译安装ansible环境
编译setuptools
server:/ansibletest # tar zxf setuptools-7.0.tar.gz
server:/ansibletest # cd setuptools-7.0/
server:/ansibletest/setuptools-7.0 # python setup.py install
编译pycrypto
server:/ansibletest # tar zxf pycrypto-2.6.1.tar.gz
server:/ansibletest # cd pycrypto-2.6.1/
server:/ansibletest/pycrypto-2.6.1 # python setup.py install
编译yaml
server:/ansibletest # tar zxf yaml-0.1.4.tar.gz
server:/ansibletest # cd yaml-0.1.4/
server:/ansibletest/yaml-0.1.4 # ./configure –prefix=/ansibletest/usr/local/yaml
server:/ansibletest/yaml-0.1.4 # make
server:/ansibletest/yaml-0.1.4 # make install
编译PyYAML
server:/ansibletest # tar zxf PyYAML-3.11.tar.gz
server:/ansibletest # cd PyYAML-3.11/
server:/ansibletest/PyYAML-3.11 # python setup.py install
编译MarkupSafe
server:/ansibletest # tar zxf MarkupSafe-0.9.3.tar.gz
server:/ansibletest # cd MarkupSafe-0.9.3/
server:/ansibletest/MarkupSafe-0.9.3 # python setup.py install
编译Jinja2
server:/ansibletest # tar zxf Jinja2-2.7.3.tar.gz
server:/ansibletest # cd Jinja2-2.7.3/
server:/ansibletest/Jinja2-2.7.3 # python setup.py install
编译ecdsa
server:/ansibletest # tar zxf ecdsa-0.11.tar.gz
server:/ansibletest # cd ecdsa-0.11/
server:/ansibletest/ecdsa-0.11 # python setup.py install
server:/ansibletest/Python-2.7.11 # make
编译paramiko
server:/ansibletest # tar xvzf paramiko-1.15.1.tar.gz
server:/ansibletest # cd paramiko-1.15.1
server:/ansibletest # pythonsetup.py install
编译simplejson
server:/ansibletest # tar xvzf simplejson-3.6.5.tar.gz
server:/ansibletest # cdsimplejson-3.6.5
server:/ansibletest # pythonsetup.py install
编译ansible
server:/ansibletest # tar xvzf ansible-1.7.2.tar.gz
server:/ansibletest # cd ansible-1.7.2/
server:/ansibletest/ansible-1.7.2 # python setup.py install
至此一个完整的ansible服务端算是配置完成
一个小小的验证
配置客户端IP
server:~ # cat /etc/ansible/hosts
[slave]
192.168.1.101
server:/ansibletest/ansible-1.7.2 # ./bin/ansible all -m ping –ask-pass
SSH password:
paramiko: The authenticity of host ‘192.168.1.101’ can’t be established.
The ssh-rsa key fingerprint is 21e1cca2719628f4859afa0b1ea805ee.
Are you sure you want to continue connecting (yes/no)?
（all是对所有分组的进行批处理）
