Oracle Linux 上安装ansible 2.3.2，在ansible 软件包里面requirements.txt明确指出了需要的软件包：

jinja2
PyYAML
paramiko
pycrypto >= 2.6
setuptools

 

其中paramiko在OL6.8的DVD中是包含的，包的名字是python-paramiko，版本是1.7，如果缺少了这个包，而且正好你的机器是可以链接intenet的，那么python的安装程序就会自动连接internet，寻找并下载paramiko软件，但是自动联网下载的paramiko是2.x版本的，其又依赖一系列其他的包，安装程序会继续下载并安装paramiko依赖的包，而有些包的版本比较高，最终在OL6.8上编译不通过，导致了ansible 2.3.2整体安装失败。

 

输出类似：

在这个时候，即使重新安装了OL6.8自带的1.7版本的paramiko，也不能解决问题，必须删除由easy_install安装的paramiko 2.x版本。

要做这个事，必须先安装pip，下载地址https://pypi.python.org/pypi/pip，下载源码包，编译安装比较简单，会提示python版本过低，下个版本pip将不再支持之类的信息，不影响使用。

 

pip list，找到安装的paramiko包的名字，然后用 pip uninstall <包名字>来删除这个包，确保系统安装了OL6.8自带的低版本的paramiko包，然后再运行ansible的安装脚本，就可以正常完成了。
