Python安装完毕后，使用pip安装其他程序，提示找不到ssl模块： 
例如这样： 
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. 
Collecting xxx 
Could not fetch URL https://pypi.python.org/simple/xxxx/: There was a problem confirming the ssl certificate: Can’t connect to HTTPS URL because the SSL module is not available. - skipping 
Could not find a version that satisfies the requirement xxx (from versions: ) 
No matching distribution found for xxx

[root@localhost ~]# python2.7.5 
Python 2.7.5 (default, Jun 3 2013, 11:08:43)

import ssl 
Traceback (most recent call last):

ImportError: No module named _ssl

1. 查看openssl安装包，发现缺少openssl-devel包 
   [root@localhost ~]# rpm -aq|grep openssl 
   openssl-0.9.8e-20.el5 
   openssl-0.9.8e-20.el5 
   [root@localhost ~]#

2. yum安装openssl-devel 
   [root@localhost ~]# yum install openssl-devel -y 
   查看安装结果 
   [root@localhost ~]# rpm -aq|grep openssl 
   openssl-0.9.8e-26.el5_9.1 
   openssl-0.9.8e-26.el5_9.1 
   openssl-devel-0.9.8e-26.el5_9.1 
   openssl-devel-0.9.8e-26.el5_9.1

3. 重新编译python 
   修改Setup文件 
   vi /usr/software/Python-2.7.5/Modules/Setup 
   修改成下面：

#Socket module helper for socket(2)
_socket socketmodule.c timemodule.c

#Socket module helper for SSL support; you must comment out the other
#socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto

1. 重新编译 
   make 
   make install

2. 测试，已可正常使用。
