python安裝完畢後，提示找不到ssl模組：
例如這樣：
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

import ssl
Traceback (most recent call last):

1. 檢視openssl安裝包，發現缺少openssl-devel包
   [[email protected] ~]# rpm -aq|grep openssl
   openssl-0.9.8e-20.el5
   openssl-0.9.8e-20.el5
   [[email protected] ~]#

2. yum安裝openssl-devel
   [[email protected] ~]# yum install openssl-devel -y
   檢視安裝結果
   [[email protected] ~]# 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. 重新編譯python
   修改Setup檔案
   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. 重新編譯
   make
   make install

2. 測試，已可正常使用。
