python安装完毕后，提示找不到ssl模块：
[root@localhost ~]# python2.7.5
Python 2.7.5 (default, Jun 3 2013, 11:08:43) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2

>>> import ssl
Traceback (most recent call last):
File "", line 1, in
File "/usr/local/python27/lib/python2.7/ssl.py", line 60, in
import _ssl # if we can't import it, let the error propagate
ImportError: No module named _ssl
>>>

2. 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 ~]#

3. 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

4. 重新编译python
#修改Setup文件
vi /usr/software/Python-2.7.5/Modules/Setup
#修改结果如下：

# 通过输入：？ssl 快速查找到定位到以下内容（备注）

# Socket module helper for socket(2)
_socket socketmodule.c timemodule.c    #去除该行注释（备注）

# 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 \      #去除该行注释（备注）
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \  #去除该行注释（备注）
-L$(SSL)/lib -lssl -lcrypto         #去除该行注释（备注）

5. 重新编译（回到python安装包路径下）
make
make install

6. 测试，已可正常使用。
