python2.7.3 problem:no module name _ssl

本文章參考與：http://www.webtop.com.au/blog/compiling-python-with-ssl-support-fedora-10-2009020237。

當我"修"好yum之後就開始修python的ssl問題。我的電腦有python的多個版本。在python2.6.6中import
ssl沒錯誤提示，在python2.7.3中import ssl則有no module name _ssl的錯誤提示。

下面是我引用上面地址的文章幷，針對我的問題所在加上註解。

==================================================

I came across this recently, having always thought
that this was part of Python.  When I installed a vanilla Fedora 10
installation, shock horror, I got this error in python!

No SSL? Unheard of! Quickly check to see if you have

OpenSSL installed.

      yum list installed | grep ssl
openssl.i686                             

      0.9.8g-12.fc10              

      installed




So the first thing I did was install the development

packages.  Normally they are required when you are compiling your own

installation of python.

Jeepers, a lot for just installing one package! 

But it serves it purpose.

      yum list installed | grep ssl
openssl.i686                             

      0.9.8g-12.fc10              

      installed
openssl-devel.i386                       

      0.9.8g-12.fc10              

      installed




Now I had to modify the file Modules/Setup.dist in

the Python source (mine was located in /usr/local/src/Python-2.6.1). 

Change the following lines (highlighted in red).

      vi Modules/Setup.dist

       ######這裡Modules/Setup.dist是在你python源碼包裡面的

212

      # 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
215

      _ssl _ssl.c \
216    

      -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
217    

      -L$(SSL)/lib -lssl -lcrypto
218
219

      # The crypt module is now disabled by default because it breaks builds
220

      # on many systems (where -lcrypt is needed), e.g. Linux (I believe).
221

      #
222

      # First, look at Setup.config; configure may have set this for you.
223
224

      #crypt cryptmodule.c # -lcrypt  # crypt(3); needs -lcrypt on some

      systems




Unfortunately, I had to remake the python

installation.  But this should be painless.  Remember, I like to

point to the specific prefix location; you may not.  It should be much

faster second time (or third time...) round.

Check that python now has ssl.

No more error!  Now we have SSL support in

雖然解決了這個ssl的問題，但是運行goagent後，會出現https網頁的CA錯誤提示。這個問題改天解決了再發表上來。
