python再centos下装setuptools

Python中当需要安装第三方python包时，可能会用到easy_install命令。easy_install是由PEAK(Python Enterprise Application Kit)开发的setuptools包里带的一个命令，所以使用easy_install实际上是在调用setuptools来完成安装模块的工作。

为了方便后续安装各种第三方python包，需要先安装setuptools。

安装setuptools的话，下面一条简单的命令就可以搞定，脚本会自动为你安装适合你系统的对应版本。

# wget https://bootstrap.pypa.io/ez_setup.py -O - | python

大部分情况下，上面的命令都可以完成setuptools的安装，不过我在CentOS系统中安装setuptools的时候，貌似没那么顺利呢，所以我的解决办法如下：

# wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | python--2014-09-18 09:27:42--  https://bootstrap.pypa.io/ez_setup.pyResolving bootstrap.pypa.io... 103.245.222.175Connecting to bootstrap.pypa.io|103.245.222.175|:443... connected.WARNING: certificate common name `*.c.ssl.fastly.net' doesn't match requested host name `bootstrap.pypa.io'.HTTP request sent, awaiting response... 200 OKLength: 10476 (10K) [text/x-python]Saving to: `STDOUT'100%[======================================================================>] 10,476      --.-K/s   in 0.1s    2014-09-18 09:27:43 (98.6 KB/s) - `-' saved [10476/10476]Downloading https://pypi.python.org/packages/source/s/setuptools/setuptools-5.7.zipTraceback (most recent call last):  File "", line 332, in   File "", line 327, in main  File "", line 287, in download_setuptools  File "", line 224, in download_file_wget  File "", line 169, in _clean_check  File "/usr/local/lib/python2.7/subprocess.py", line 511, in check_call▽  raise CalledProcessError(retcode, cmd)subprocess.CalledProcessError: Command '['wget', 'https://pypi.python.org/packages/source/s/setuptools/setuptools-5.7.zip', '--quiet', '--output-document', '/alidata/data/python/setuptools-5.7.zip']' returned non-zero exit status 1

自动安装脚本需要去下载一个文件，可是下载不下来，卡在Downloading这里了，只好改成手动方式下载了

# wget https://pypi.python.org/packages/source/s/setuptools/setuptools-5.7.zip --no-check-certificate--2014-09-18 09:29:15--  https://pypi.python.org/packages/source/s/setuptools/setuptools-5.7.zipResolving pypi.python.org... 103.245.222.223Connecting to pypi.python.org|103.245.222.223|:443... connected.WARNING: certificate common name `www.python.org' doesn't match requested host name `pypi.python.org'.HTTP request sent, awaiting response... 200 OKLength: 1114918 (1.1M) [application/zip]Saving to: `setuptools-5.7.zip'100%[=========================================================================>] 1,114,918   41.3K/s   in 34s     2014-09-18 09:29:49 (32.3 KB/s) - `setuptools-5.7.zip' saved [1114918/1114918]

下面把自动安装脚本也下载下来，让这个脚本替我们去安装

[root@AY1308142020485982a0Z python]# wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py--2014-09-18 09:29:57--  https://bootstrap.pypa.io/ez_setup.pyResolving bootstrap.pypa.io... 103.245.222.175Connecting to bootstrap.pypa.io|103.245.222.175|:443... connected.WARNING: certificate common name `*.c.ssl.fastly.net' doesn't match requested host name `bootstrap.pypa.io'.HTTP request sent, awaiting response... 200 OKLength: 10476 (10K) [text/x-python]Saving to: `ez_setup.py'100%[==============================>] 10,476      --.-K/s   in 0s      2014-09-18 09:29:58 (55.8 MB/s) - `ez_setup.py' saved [10476/10476]

最后完成安装

# python ez_setup.py
