基于python+django的博客程序-djblog/youflog的下载和安装

# apt-get install git -y
# git clone git://github.com/ichuan/djblog.git

    然后创建数据库，例如 mysql数据库：# mysql -uroot -prootspassword -e 'create database djblog'
    拷贝 local_settings.default.py 为 local_settings.py，修改里面的数据库配置。还有其他配置可以改.
    执行 python manage.py syncdb 同步数据库.
    执行 python manage.py runserver 0.0.0.0:9003 启动临时服务器.
(建议用命令nohup python manage.py runserver 0.0.0.0:9003 > log &)
    浏览器访问 http://ur-vps-ip:9003，后台地址是 http://ur-vps-ip:9000/admin/，口令在第 3 步时创建.登录的用户名为root,密码为你自己设置的密码。
(如果忘记登录密码了，可运行命令：进到 /root/djblog 下，执行 python manage.py changepassword root）
    在后台的sites里更改默认的example.com为你自己的域名（RSS输出中的链接会使用到）.
from https://github.com/ichuan/djblog

demo site:
http://as3.brite.biz:9003，
http://as3.brite.biz:10000/ (类似的程序：youflog(http://code.google.com/p/youflog),它的0.3版我安装成功)

注意： 如果执行 python manage.py syncdb遇到出错提示：No module named MySQLdb，
各种解决办法：
  1. easy_install mysql-python (mix os)
  2. pip install mysql-python (mix os)
  3. 自行编译：mysqldb is a module for Python that doesn't come pre-installed or with Django. You can download mysqldb here.   http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python, http://mysql-python.sourceforge.net/FAQ.html‎
  4. apt-get install python-mysqldb (Ubuntu, ...)
  5. cd /usr/ports/databases/py-MySQLdb && make install clean (FreeBSD)
  6. yum install MySQL-python (Fedora, CentOS ...)
  7.   
    （7.If you are running on Vista, you may want to check out the Bitnami Django stack. It is an all-in-one stack of Apache, Python, MySQL, etc. packaged with Bitrock crossplatform installers to make it really easy to get started. It runs on Windows, Mac and Linux. Oh, and is completely free.)
 (Download and install ActivePython-http://www.activestate.com/activepython/downloads#
    Open Command Prompt
    Type "pypm install mysql-python -g"
    Read the notes specific to this package.
I think pypm is more powerful and reliable than easy_install?)

或者，你可以去这里 http://www.djangoproject.com/r/python-mysql/ 下载安装 MySQLdb.

(Install MySQL module for Python

There’s a package (Python module) that interfaces a Python Script with a MySQL database back-end.  It’s called MySQLdb.  For example:
[root@puma ~] python2.4
Python 2.4.3 (#1, Jun 18 2012, 08:55:23) 
>>> import MySQLdb
>>> 
[root@puma ~] python2.6
Python 2.6.5 (r265:79063, Jun  8 2010, 15:27:41) 
>>> import MySQLdb
>>> 
[root@puma ~] python2.7
Python 2.7 (r27:82500, Aug 29 2012, 15:28:26) 
>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named MySQLdb
>>> 
[root@puma ~]
Oops.  So, that last one is a bit of a problem.  No problem, thought I.  That’s what pip is for:
[root@puma ~] pip-2.7 install MySQLdb
Downloading/unpacking MySQLdb
  Real name of requirement MySQLdb is MySQLdb
  Could not find any downloads that satisfy the requirement MySQLdb
No distributions at all found for MySQLdb
Storing complete log in /root/.pip/pip.log
[root@puma ~]
Hmm.  Not as easy as I hoped.  Okay, so, what is the module actually called?
[root@puma ~] pip-2.7 search MySQLdb
jaraco.mysql              - MySQLDB-compatible MySQL wrapper by Jason R. Coombs
mysqldbda                 - MySQL Database adapter
raisin.mysqldb            - UNKNOWN
sqlShort                  - A tiny wrapper for the Python modules MySQLdb and Sqlite
sqlwitch                  - sqlwitch offers idiomatic SQL generation on top of MySQLdb.
torndb                    - A lightweight wrapper around MySQLdb.  Originally part of the Tornado framework.
Hmm.  I’m still not sure.  None of those look quite right, though many of them look interesting.
Okay, we know that we have MySQLdb for python2.4 and python2.6, so let’s see where those come from:
[root@puma ~] locate MySQLdb
/usr/lib64/python2.4/site-packages/MySQLdb
/usr/lib64/python2.4/site-packages/MySQLdb/__init__.py
/usr/lib64/python2.4/site-packages/MySQLdb/__init__.pyc
/usr/lib64/python2.4/site-packages/MySQLdb/__init__.pyo
/usr/lib64/python2.4/site-packages/MySQLdb/connections.py
...
/usr/lib64/python2.4/site-packages/MySQLdb/constants/__init__.pyc
/usr/lib64/python2.4/site-packages/MySQLdb/constants/__init__.pyo
/usr/share/doc/MySQL-python-1.2.3/MySQLdb.txt
[root@puma ~]
Grrr.  That’s distressing.  So there’s no file/directory called MySQLdb except for Python2.4  So, where is the one for Python2.6?  Back to the drawing board:
[cs304@puma ps2] python2.6
Python 2.6.5 (r265:79063, Jun  8 2010, 15:27:41)

Wow, that was quite a journey.  So, it seems the MySQLdb module is inside an “egg” called MySQL_python.  Can we find *that* with pip?
Okay, we can, and we were able to upgrade it.

Darn!  pip never sets the directory permissions properly, and I always forget. (Oh, and I see that the upgrade has created a MySQLdb directory, instead of hiding the module inside an egg.) A quick fix:
[root@puma ~] opendir /usr/local/lib/python2.6/site-packages/
And we’re done:
[anderson@puma ~] python2.6 -c 'import MySQLdb'
whew!  Now, can we finally install MySQLdb for python2.7?

用uWSGI替代fastcgi部署django应用

部署过程

首先下载编译 uwsgi：http://projects.unbit.it/downloads/uwsgi-latest.tar.gz
wget  http://projects.unbit.it/downloads/uwsgi-latest.tar.gz
tar zxvf  uwsgi-latest.tar.gz
cd  uwsgi-1.9.20
make
编译完毕。
执行文件为～/uwsgi-1.9.20/uwsgi
我是 ubuntu 系统，需要额外装个 libxml2-dev 库：sudo apt-get install libxml2-dev

 启动 uwsgi：
～/uwsgi-1.9.20/uwsgi -s /tmp/uwsgi.sock -C -M -p 4 -t 30 --limit-as 128 -R 10000 --vhost -d /tmp/uwsgi.log --pidfile /tmp/uwsgi.pid --pythonpath /var/
表示用 unix socket 方式执行 uwsgi，-C 表示将 /tmp/uwsgi.sock 文件权限改成 666 以便 nginx 可以读取，-M 表示启动管理进程，-p 4 表示预生成 4 个 worker 子进程，-t 30 是 cgi 程序超时，--limit-as 128 表示限制内存最大 128M，-R 10000 表示每个 worker 处理的最大请求数，--vhost 表示启用虚拟服务器，-d /tmp/uwsgi.log 表示以守护进程方式启动，指定日志文件。/var/为你的网站目录的上一层目录。（我的网站目录为/var/djblog/).如果你的网站目录为/root/xxx/,那么你需把/var/改为/root/,再运行一次该命令：
uwsgi -s /tmp/uwsgi.sock -C -M -p 4 -t 30 --limit-as 128 -R 10000 --vhost -d /tmp/uwsgi.log --pidfile /tmp/uwsgi.pid --pythonpath /root/

 这个命令可以放入 /etc/rc.local 作为开机自启动。
nginx 的 server 块配置如下：
location / {
    uwsgi_pass  unix:///tmp/uwsgi.sock;
    uwsgi_param UWSGI_CHDIR  /var/djblog;
    uwsgi_param UWSGI_SCRIPT wsgi;
    include     uwsgi_params;
}
上面的配置的前提是，你的 django工程在 /var/djblog，并且在该目录下有个 wsgi.py 文件。文件内容如下：
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'djblog.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
如此配置好后，重启 nginx 就可以了。
如果要多加一个网站，只需在 nginx 配置中新加个 server 块，改变下 UWSGI_CHDIR的值为你新网站的根目录即可。
如果要让 uwsgi 重新载入，可以执行：
kill -HUP `cat /tmp/uwsgi.pid`
如果要停止 uwsgi，可以给它的 master 进程发送 SIGINT信号：
kill -SIGINT `cat /tmp/uwsgi.pid`
uwsgi 的更多配置在此。

示例： http://dj.brite.biz:81/ ，http://yl.brite.biz:81/

以上的 wsgi.py文件如果不行的话，可改为：
import os,sys
if not os.path.dirname(__file__) in sys.path[:1]:
    sys.path.insert(0, os.path.dirname(__file__))
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
from django.core.handlers.wsgi import WSGIHandler
application = WSGIHandler()
