更新新的Django和Python 2.7。*與Dreamhost上的virtualenv（帶有乘客）

Question

Dreamhost是一個很棒的小項目主機。這也是Django友好的託管。除python和Django版本之外的所有東西都已經過時了。那麼這是一整天的工作來弄清楚如何更新Python 2.7.3，Django 1.4上的dreamhost，我真的想與誰分享

Answer 1

我目前有私人服務器，一個shell帳戶和一點運氣。因此，這裏是我做的：

1. SSH到你的主機升級蟒蛇

   cd ~ 
   mkdir tmp 
   cd tmp 
   wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz 
   tar zxvf Python-2.7.3.tgz 
   cd Python-2.7.3 
   ./configure --enable-shared --prefix=$HOME/Python27 --enable-unicode=ucs4 
   make 
   make install 
   

2. 配置系統使用我們的新的Python。開放的〜/ .bashrc，並添加下面一行

   export PATH="$HOME/Python27/bin:$PATH" 
   export LD_LIBRARY_PATH=$HOME/Python27/lib 
   
   #save it and run 
   source ~/.bashrc 
   

   你現在可以which python

3. 檢查Python版本安裝easy_install，pip

   cd ~/tmp 
   wget http://peak.telecommunity.com/dist/ez_setup.py 
   python ez_setup.py 
   easy_install pip 
   # Or even shorter 
   wget https://bootstrap.pypa.io/get-pip.py 
   python get-pip.py 
   

4. 安裝virtualenv

   pip install virtualenv 
   virtualenv $HOME/<site>/env 
   #Switch to virtualenv 
   source $HOME/<site>/env/bin/activate 
   

   你也可以添加ENV路徑bashrc

   export PATH="$HOME/<site>/env/bin/:$PATH" 
   source ~/.bashrc 
   

5. 安裝Django和其他一切

   pip install django 
   pip install .... 
   pip install .... 
   pip install .... 
   

6. 創建項目

   cd $HOME/<site>/ 
   python $HOME/<site>/env/bin/django-admin.py startproject project 
   

7. 在HOME/<site>/創建passenger_wsgi.py有以下內容

   import sys, os 
   cwd = os.getcwd() 
   sys.path.append(cwd) 
   sys.path.append(cwd + '/project') #You must add your project here or 500 
   
   #Switch to new python 
   #You may try to replace $HOME with your actual path 
   if sys.version < "2.7.3": os.execl("$HOME/<site>/env/bin/python", 
       "python2.7.3", *sys.argv) 
   
   sys.path.insert(0,'$HOME/<site>/env/bin') 
   sys.path.insert(0,'$HOME/<site>/env/lib/python2.7/site-packages/django') 
   sys.path.insert(0,'$HOME/<site>/env/lib/python2.7/site-packages') 
   
   os.environ['DJANGO_SETTINGS_MODULE'] = "project.settings" 
   import django.core.handlers.wsgi 
   application = django.core.handlers.wsgi.WSGIHandler() 
   

或這樣

import sys, os 

BASE_DIR = os.path.dirname(os.path.abspath(__file__)) 

sys.path.append(os.path.join(BASE_DIR)) #You must add your project here or 500 

#Switch to new python 
#You may try to replace $HOME with your actual path 
PYTHON_PATH = os.path.join(BASE_DIR, 'env', 'bin', 'python') 
if sys.executable != PYTHON_PATH: 
    os.execl(PYTHON_PATH, "python2.7.12", *sys.argv) 

如果使用的django 1.7，替換

from django.core.wsgi import get_wsgi_application 
application = get_wsgi_application() 

最後兩行

享受：d

Dreamhost上蟒新版本將不再返回sys.executable所以你這是我的版本passenger_wsgi的

import sys, os 

VIRTUAL_ENV_PYTHON = 'venv-python' # Python > 2.7.6 dreamhost not return sys.executable 
BASE_DIR = os.path.dirname(os.path.abspath(__file__)) 

def is_venv_python(): 
    if len(sys.argv) > 0: 
     last_item = sys.argv[len(sys.argv)-1] 
     if last_item == VIRTUAL_ENV_PYTHON: 
      return True 
    return False 

sys.path.append(os.path.join(BASE_DIR)) #You must add your project here or 500 

#Switch to new python 

PYTHON_PATH = os.path.join(BASE_DIR, 'env', 'bin', 'python') 
if not is_venv_python(): 
    os.execl(PYTHON_PATH, "python2.7.12", *sys.argv + [VIRTUAL_ENV_PYTHON]) 

sys.path.insert(0, os.path.join(BASE_DIR, 'env', 'bin')) 
sys.path.insert(0, os.path.join(
    BASE_DIR, 'env', 'lib', 'python2.7', 'site-packages' 
)) 

Answer 2

目前Dreamhost的更新服務器到Ubuntu 12.04，和我有一個錯誤：

Import Error: <path-to-python>/_io.so undefined symbol: PyUnicodeUCS2_Decode 

編譯自定義python並運行「python ez_setup」後編譯爲

。PY」

的解決方案是編譯--enable-unicode的= UCS4蟒蛇在步驟1

./configure --enable-shared --prefix=$HOME/Python27 --enable-unicode=ucs4
