**安裝的時候需要很多依賴 ，因為ansible是基於Python寫出來的，所以需要先安裝Python，Python版本>=2.6才能安裝Ansible。

1、安裝python

Yum install python*
Ansible的安裝是依賴一些模塊的，所以首先安裝依賴模塊再安裝Ansible

2、安裝setuptools模塊

https://pypi.python.org/packages/source/s/setuptools/setuptools-7.0.tar.gz

#?tar?-xvzf?setuptools-7.0.tar.gz??
#?cd?setuptools-7.0??
#?python?setup.py?install??
 

3、安裝pycrypto模塊

https://pypi.python.org/packages/source/p/pycrypto/pycrypto-2.6.1.tar.gz

#?tar?-xvzf?pycrypto-2.6.1.tar.gz??
#?cd?pycrypto-2.6.1??
#?python?setup.py?install??

4、安裝PyYAML模塊

http://pyyaml.org/download/libyaml/yaml-0.1.5.tar.gz

#?tar?-xvzf?yaml-0.1.5.tar.gz??
#?cd?yaml-0.1.5??
#?./configure?--prefix=/usr/local??
#?make?&&?make?install??

PyYAMAL依賴於yaml包所以需要先安裝yaml
https://pypi.python.org/packages/source/P/PyYAML/PyYAML-3.11.tar.gz

#?tar?-xvzf?PyYAML-3.11.tar.gz??
#?cd?PyYAML-3.11??
#?python?setup.py?install??   

5、安裝jinja2模塊

https://pypi.python.org/packages/source/M/MarkupSafe/MarkupSafe-0.9.3.tar.gz

#?tar?-xvzf?MarkupSafe-0.9.3.tar.gz??
#?cd?MarkupSafe-0.9.3??
#?python?setup.py?install??

https://pypi.python.org/packages/source/J/Jinja2/Jinja2-2.7.3.tar.gz

#?tar?-xvzf?Jinja2-2.7.3.tar.gz??
#?cd?Jinja2-2.7.3??
#?python?setup.py?install??

6、安裝paramiko模塊

https://pypi.python.org/packages/source/e/ecdsa/ecdsa-0.11.tar.gz

#?tar?-xvzf?ecdsa-0.11.tar.gz??
#?cd?ecdsa-0.11??
#?python?setup.py?install??

https://pypi.python.org/packages/source/p/paramiko/paramiko-1.15.1.tar.gz

#?tar?-xvzf?paramiko-1.15.1.tar.gz??
#?cd?paramiko-1.15.1??
#?python?setup.py?install??

7、安裝simplejson模塊（如果是Python2.版本的話可以忽略此模塊的安裝）

https://pypi.python.org/packages/source/s/simplejson/simplejson-3.6.5.tar.gz

#?tar?-xvzf?simplejson-3.6.5.tar.gz??
#?cd?simplejson-3.6.5??
#?python?setup.py?install??

8、安裝ansible模塊

https://github.com/ansible/ansible/archive/v1.7.2.tar.gz

#?tar?-xvzf?ansible-1.7.2.tar.gz??
#?cd?ansible-1.7.2??
#?python?setup.py?install??

9、配置Ansible

# mkdir /etc/ansible
#cp /home/cjx/ansible/examples/hosts(ansible)  /etc/ansible/

修改配置文件將一下三個配置去註釋

host_key_checking = False    是否檢查主機密鑰 （跳過ssh 首次連接提示驗證部分，False表示跳過）
log_path = /var/log/ansible.log     日誌文件存放路徑
accelerate_multi_key = yes   開啟加速

在hosts上添加節點機器

[haha]
192.168.1.21

10、測試Ansible

[root@localhost .ssh]# ansible all -m ping -K
sudo password: 
192.168.1.21 | success >> {
    "changed": false, 
    "ping": "pong"
}

[root@localhost .ssh]# 

測試成功！

11、Ansible出錯解決方案

出錯1：安裝yaml的時候報錯

1.# python setup.py install
2.libyaml is not found or a compiler error: forcing --without-libyaml
3.(if libyaml is installed correctly, you may need to
4.specify the option --include-dirs or uncomment and
5.modify the parameter include_dirs in setup.cfg)
6.running install_lib
7.running install_egg_info
8.Removing /usr/lib64/python2.6/site-packages/PyYAML-3.11-py2.6.egg-info
9.Writing /usr/lib64/python2.6/site-packages/PyYAML-3.11-py2.6.egg-info

如果繼續安裝的話在安裝Ansible會報錯：

 Traceback (most recent call last):
·  File "/usr/local/src/ansible-devel/bin/ansible", line 36, in <module>
·  from ansible.runner import Runner
·  File "/usr/local/src/ansible-devel/lib/ansible/runner/__init__.py", line 62, in <module>
·  from Crypto.Random import atfork
·  File "/usr/lib64/python2.6/site-packages/Crypto/Random/__init__.py", line 29, in <module>
·  from Crypto.Random import _UserFriendlyRNG
·  File "/usr/lib64/python2.6/site-packages/Crypto/Random/_UserFriendlyRNG.py", line 38, in <module>
·  from Crypto.Random.Fortuna import FortunaAccumulator
·  File "/usr/lib64/python2.6/site-packages/Crypto/Random/Fortuna/FortunaAccumulator.py", line 39, in <module>
·  import FortunaGenerator
·  File "/usr/lib64/python2.6/site-packages/Crypto/Random/Fortuna/FortunaGenerator.py", line 34, in <module>
·  from Crypto.Util.number import ceil_shift, exact_log2, exact_div
·  File "/usr/lib64/python2.6/site-packages/Crypto/Util/number.py", line 56, in <module>
·  if _fastmath is not None and not _fastmath.HAVE_DECL_MPZ_POWM_SEC:
·  AttributeError: ‘module‘ object has no attribute ‘HAVE_DECL_MPZ_POWM_SEC‘

根據報錯提示可以知道主要是因為pycrypto包依賴的GMP版本不對，打開/usr/lib64/python2.6/site-packages/Crypto/Util/number.py可以看到56行的註釋要求你libgmp版本在V5以上，而系統現在的版本是4.1.4，可以把這行註釋掉，永久解決的話是更新升級libgmp的版本

出錯2：安裝 pycrypto的時候會報錯

安裝Python的時候必須要安裝python-devel否則在安裝 pycrypto的時候會報錯，報錯如下圖所示：

（error: Setup script exited with error: command ‘gcc‘ failed with exit status 1）

運行Ansible會報如下錯誤：

pkg_resources.DistributionNotFound: pycrypto>=2.6

解決：把Python的依賴包python-devel-2.6.6-66.el6_8.x86_64安裝上去即可

# yum install python-devel

基於Centos6.6（7.2）源碼安裝Ansible
