安装python2.6.6到ubuntu12.04

由于服务器在python2.6.6上跑，我也得安装2.6.6

linux自带的是2.7

在网上下载2.6.6版本， https://www.python.org/download/releases/2.6.6/

下载后解压，根据其中的readme来安装。

make之后发现缺了很多bit文件，导致如下报错。到处搜索解决问题。

Python build finished, but the necessary bits to build these modules were not found:
_bsddb             _curses            _curses_panel   
_sqlite3           _ssl               _tkinter        
bsddb185           bz2                dl              
gdbm               imageop            linuxaudiodev   
ossaudiodev        readline           spwd            
sunaudiodev        zlib     

打开其中的setup.py文件，由于我是64为的linux（ubuntu）

将

lib_dirs = self.compiler.library_dirs + [
            '/lib64', '/usr/lib64',
            '/lib', '/usr/lib',
            ]

修改为

lib_dirs = self.compiler.library_dirs + [
            '/lib64', '/usr/lib64',
            '/lib', '/usr/lib', '/usr/lib/x86_64-linux-gnu',
            ]

然后装一些开发库，zlib1g-dev, libreadline-dev, libssl-dev, libsqlite3-dev, libbz2-dev, libgdbm-dev, libncurses5-dev.如下：

sudo apt-get install build-essential zlib1g-dev libbz2-dev libssl-dev libreadline-dev libncurses5-dev libsqlite3-dev libgdbm-dev libdb-dev libexpat-dev libpcap-dev liblzma-dev libpcre3-dev

对于ubuntu12.04或者以上版本安装python2.7以下版本（如2.6.6,2.6.8），有一点非常要注意，那就是ssl2以及被弃用了，所以无论怎么添加lib，都无法解决failed to install _ssl，对于这种情况，参考网页为http://blog.schmichael.com/2012/05/29/building-python-2-6-8-on-ubuntu-12-04/，按照这个参考网页修改 ssl部分 的 代码，如下：

或者下载我修改好了的代码http://download.csdn.net/detail/ranky2009/8319645，替换掉python2.6.6中文件即可。

安装了python2.6，第一次执行时报错：

error while loading shared libraries: libpython2.6.so.1.0: cannot open shared object file: No such file or directory

解决方法如下：

1.编辑      vi /etc/ld.so.conf 

如果是非root权限帐号登录，使用 sudo vi /etc/ld.so.conf （也查看/etc/ld.so.conf.d/*.conf，如果其中有文件加入了你的python2.6的lib库，就不需要再添加）。

添加上python2.6的lib库地址，如我的/usr/local/lib，保存文件

2.执行 /sbin/ldconfig -v命令，如果是非root权限帐号登录，使用 sudo  /sbin/ldconfig -v。这样 ldd 才能找到这个库，执行python2.7就不会报错了
