nginx+uwsgi+django报错：[Errno 13] Permission denied: ‘/root/.python-eggs’

ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

[Errno 13] Permission denied: '/root/.python-eggs'

实际上也就是：安装的MySQL_python-1.2.3c1-py2.6-linux-x86_64.egg需要解压到/root/.python-eggs目录，而Apache访问的用户并没有该目录的write权限。

一个fix方法是在修改你的django.wsgi文件，添加PYTHON_EGG_CACHE的设置，先

mkdir /tmp/.python-eggs

uwsgi.py 加上：

if sys.platform <> "win32":
os.environ['PYTHON_EGG_CACHE'] = '/tmp/.python-eggs'

另一个简单的fix的方法就是将MySQL解压成目录结构：

$ cd /usr/lib/python2.6/site-packages/ (or wherever your site-packages are)
$ file MySQL_python-1.2.3c1-py2.6-linux-x86_64.egg
$ unzip -t MySQL_python-1.2.3c1-py2.6-linux-x86_64.egg
$ mv MySQL_python-1.2.3c1-py2.6-linux-x86_64.egg foo.zip
$ mkdir MySQL_python-1.2.3c1-py2.6-linux-x86_64.egg
$ cd MySQL_python-1.2.3c1-py2.6-linux-x86_64.egg/
$ unzip ../foo.zip
$ rm ../foo.zip
