Linux CentOS release 6.9 (Final)

全新安装的CentOS系统，打算用来做Python开发，但是系统默认的是Python2.6.6，开发中经常用到Python2.7以及Python3，因此需要安装多个环境，virtualenv正好满足这个需求。

  • 首先查看一下系统当前的python版本：
# python -V
Python 2.6.6
  • 下载我们需要的Python版本：
# wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz
# wget https://www.python.org/ftp/python/3.5.6/Python-3.5.6.tgz
  • 解压
# tar -zxvf Python-2.7.14.tgz
# tar -zxvf Python-3.5.6.tgz
  • 在安装前需要先安装一些基础环境
# yum -y install gcc gcc-c++
# yum -y install openssl openssl-devel
# yum -y install openssl openssl-devel
# yum -y install bzip2 bzip2-devel
# yum -y install zlib zlib-devel
  • 安装sqlite3
# wget https://www.sqlite.org/2017/sqlite-autoconf-3170000.tar.gz --no-check-certificate
# tar zxvf sqlite-autoconf-3170000.tar.gz
# cd sqlite-autoconf-3170000
# ./configure --prefix=/usr/local/sqlite3 --disable-static --enable-fts5 --enable-json1 CFLAGS="-g -O2 -DSQLITE_ENABLE_FTS3=1 -DSQLITE_ENABLE_FTS4=1 -DSQLITE_ENABLE_RTREE=1"
  • 编译安装Python27
# cd Python-2.7.14
# ./configure --prefix=/usr/local/python27
# make
# make install

# cd ../Python-3.5.6
# LD_RUN_PATH=/usr/local/sqlite3/lib ./configure LDFLAGS="-L/usr/local/sqlite3/lib" CPPFLAGS="-I /usr/local/sqlite3/include"  --prefix=/usr/local/python35
# LD_RUN_PATH=/usr/local/sqlite3/lib make
# LD_RUN_PATH=/usr/local/sqlite3/lib sudo make install

OK，完成以上步骤后，算是万事俱备了，接下来开始安装virtualenv

# pip install virtualenv
-bash: pip: command not found

糟糕，系统自带的python没有pip
好吧，那先安装pip
之前有个方法就是用get-pip.py安装，先尝试一下.

# wget https://bootstrap.pypa.io/get-pip.py
# python get-pip.py
Traceback (most recent call last):
  File "get-pip.py", line 20651, in <module>
    main()
  File "get-pip.py", line 197, in main
    bootstrap(tmpdir=tmpdir)
  File "get-pip.py", line 82, in bootstrap
    import pip._internal
  File "/tmp/tmpwGkrNs/pip.zip/pip/_internal/__init__.py", line 42, in <module>
  File "/tmp/tmpwGkrNs/pip.zip/pip/_internal/cmdoptions.py", line 16, in <module>
  File "/tmp/tmpwGkrNs/pip.zip/pip/_internal/index.py", line 536
    {str(c.version) for c in all_candidates},
                      ^
SyntaxError: invalid syntax

一言不合就报错，了解了一下{str(c.version) for c in all_candidates},是因为python的版本太低，可以把系统的python2.6.6改成2.7，目前暂时不太想改，万一哪天需要用到2.6呢，所以放弃这个方法，那先安装setuptools吧。

# wget http://peak.telecommunity.com/dist/ez_setup.py
# python ez_setup.py install
Downloading http://pypi.python.org/packages/2.6/s/setuptools/setuptools-0.6c11-py2.6.egg

    egg = download_setuptools(version, delay=0)
  File "ez_setup.py", line 158, in download_setuptools
    src = urllib2.urlopen(url)
  File "/usr/lib64/python2.6/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib64/python2.6/urllib2.py", line 397, in open
    response = meth(req, response)
  File "/usr/lib64/python2.6/urllib2.py", line 510, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib64/python2.6/urllib2.py", line 435, in error
    return self._call_chain(*args)
  File "/usr/lib64/python2.6/urllib2.py", line 369, in _call_chain
    result = func(*args)
  File "/usr/lib64/python2.6/urllib2.py", line 518, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 403: SSL is required

服务器返回403，要求需要https请求，看来这个方式也行不通了。
继续尝试......

其实到这里已经可以使用easy_install 来安装模块了，不过还是想安装pip，尝试一下用easy_install安装pip。

开心，成功了。开始安装virtualenv

# pip install virtualenv
Downloading/unpacking virtualenv
  Downloading virtualenv-16.0.0.tar.gz (2.0MB): 2.0MB downloaded
  Running setup.py egg_info for package virtualenv
    virtualenv requires Python 2.7 or higher.
    Complete output from command python setup.py egg_info:
    virtualenv requires Python 2.7 or higher.

----------------------------------------
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-root/virtualenv
Storing complete log in /root/.pip/pip.log

然而，virtualenv requires Python 2.7 or higher.，virtualenv 并不支持python2.6。
头疼，没办法，只能更改系统的python版本了。

# mv /usr/bin/python /usr/bin/python26
# ln -s /usr/local/python27/bin/python /usr/bin/python
# python -V
Python 2.7.14

更改yum,使其能正常运行

# vim /usr/bin/yum

把开头一行#!/usr/bin/python改为#!/usr/bin/python26即可。

这样一来，pip需要重装，现在是python2.7，用get-pip.py安装就好。

# wget https://bootstrap.pypa.io/get-pip.py
# python get-pip.py

OK，大功告成！

创建两个python环境

# mkdir -p /usr/envs
# cd /usr/envs/
# virtualenv -p /usr/local/python27/bin/python py27
Running virtualenv with interpreter /usr/local/python27/bin/python
New python executable in /usr/envs/py27/bin/python
Installing setuptools, pip, wheel...done.

# virtualenv -p /usr/local/python35/bin/python3 py35
Running virtualenv with interpreter /usr/local/python35/bin/python3
Using base prefix '/usr/local/python35'
New python executable in /usr/envs/py35/bin/python3

Installing setuptools, pip, wheel...done.

切换到python3环境

# source /usr/envs/py35/bin/activate
(py35) #

退出python3环境

# deactivate

接下来可以愉快地撸代码了~
