Cent OS6.7编译安装python2.7

[root@node3 ~]# wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz [root@node3 ~]# wget http://archive.ipython.org/release/1.2.1/ipython-1.2.1.tar.gz[/code]    2、准备编译环境
2.1python编译所需的包

[root@node3 ~]# yum install readline-devel
[root@node3  ~]#  yum  install  zlib*
        2.2安装开发包组
[root@node3  ~]# yum groupinstall "Development tools"
二、编译安装

1、python编译安装
[root@node3 ~]# tar xf Python-2.7.12.tar.xz
[root@node3 ~]# cd Python-2.7.12
[root@node3 Python-2.7.12]# ./configure --prefix=/usr/local/python27
[root@node3 Python-2.7.12]# make && make install
  2、ipython模块编译安装
[root@node3 ~]# tar xf ipython-1.2.1.tar.gz
[root@node3 ~]# cd ipython-1.2.1
[root@node3 ipython-1.2.1]# /usr/local/python27/bin/python2.7 setup.py install
[root@node3 ipython-1.2.1]# /usr/local/python27/bin/python2.7 setup.py build
  3、添加软连接

[root@node3 ~]# ln -sv /usr/local/python27/bin/python2.7 /usr/bin/python27
`/usr/bin/python27' -> `/usr/local/python27/bin/python2.7'
[root@node3 ~]# ln -sv /usr/local/python27/bin/ipython /usr/bin/
`/usr/bin/ipython' -> `/usr/local/python27/bin/ipython'


三、setuptools的编译安装
1、准备源码
[root@node3 ~]# wget https://pypi.python.org/packages/e8/68/f968ebc015c7e0021e76b60b8cfd29f9ffbae4b3b58d96ad20045a99562e/setuptools-32.3.1.zip#md5=efa64884dd41d2b0456e19745bb29fdc[/code]  2、解压缩
[root@node3 ~]# unzip setuptools-32.3.1.zip
  3、编译安装
[root@node3 setuptools-32.3.1]# /usr/local/python27/bin/python2.7 setup.py build
[root@node3 setuptools-32.3.1]# /usr/local/python27/bin/python2.7 setup.py install
 遇见报错：
File "/root/setuptools-1.1.1/setuptools/command/bdist_egg.py", line 545, in make_zipfile
z = zipfile.ZipFile(zip_filename, mode, compression=compression)
File "/usr/local/python27/lib/python2.7/zipfile.py", line 736, in __init__
"Compression requires the (missing) zlib module"
RuntimeError: Compression requires the (missing) zlib module
此处的报错为没安装zlib压缩模块，这个模块应在python编译安装之前安装。此时，只有重新编译python，方能解决。

四、安装MySQLdb模块
1、下载 https://pypi.python.org/pypi/MySQL-python/1.2.5 
[root@node3 ~]# wget https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip#md5=654f75b302db6ed8dc5a898c625e030c[/code] 2、编译安装

[root@node3 ~]# unzip MySQL-python-1.2.5.zip
[root@node3 MySQL-python-1.2.5]# /usr/local/python27/bin/python2.7 setup.py build
[root@node3 MySQL-python-1.2.5]# /usr/local/python27/bin/python2.7 setup.py install
遇见报错：
File "/root/MySQL-python-1.2.5/setup_posix.py", line 25, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
这个报错原因是没有安装mysql，安装mysql即可。
