bluehost-python升级
I have a shared host on Bluehost.com, and want to have a lot of python libraries and applications to work on it.
Since it’s a shared host, I can’t install python libs, while I love ez_setup so much, I can’t live on python world without it.
Knowing from python-cn group, that I could build and use my own python on it. I should have got this solution earlier, this might be simple and naive for linux users.
OK, now let’s do it:
——————————————–
1. you must have shell access, please contact the bluehost support for a shell access
2. my dev box is windows xp, so I use putty, to connect my host 2maomao.com
3. then use wget to download latest python, unzip it
wget http://www.python.org/ftp/python/2.5.2/Python-2.5.2.tgz
tar xvzf Python-2.5.2.tgz
4. this step is critical, you need to replace “twomaom1″ to your own user name below:
cd Python-2.5.2
./configure --prefix=/home/twomaom1/mypython --enable-unicode=ucs4
make
make install
5. now, let’s use the new python instead of the old one, you need to
a). cd ~
b). use any editor(I use vim), to edit your “.bashrc” file, add the following line at the end of the file
export PATH=/home/twomaom1/mypython/bin/:$PATH
export PYTHONPATH="/home/twomaom1/mypython/lib/python2.5:$PYTHONPATH"
6. now type “bash” and enter to refresh the shell, type “python -V” to view the python version.
You should already been successful.
from now on, easy_install or “python setup.py”, it’s your choice
Oh…don’t forget, in your python script, use the correct python path in the head, like mine:
#!/home/twomaom1/bin/python
Enjoy it ~!
0. 安装自己的Python，参见：configure your own python 2.5.2 on bluehost
1. 安装完以后重启shell(直接敲bash回车或者重连putty)
2. 下载并安装ez_setup
3. 我用mysql，所以安装mysql-python: easy_install mysql-python
4. 安装flup和django：
easy_install flup
下载django包，解压（我放到了/home/twomaom1/django/src目录），按照指令安装
5、设置子域名，我设置的是code.fayaa.com，网络不熟啊，至今不是很懂，似乎一些apache设置以及django默认配置的问题，搞个子域名比较好办
6、在该子域名的目录下（我的是：/home/twomaom1/public_html/fayaa/code/），新建.htaccess，内容如下：
AddHandler fcgid-script .fcgi
RewriteEngine On
RewriteBase /
#static file setting
RewriteRule ^(static/.*)$ -
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ t.fcgi/$1
7. 新建个t.fcgi，改为可执行（chmod +x t.fcgi），内容如下：
#!/home/twomaom1/twomaom1/bin/python
import sys, os
# Add a custom Python path.
sys.path.insert(0, "/home/twomaom1/twomaom1/python")
sys.path.insert(0, "/home/twomaom1/django")
os.chdir("/home/twomaom1/django/code")
os.environ['DJANGO_SETTINGS_MODULE'] = "code.settings"
from django.core.servers.fastcgi import runfastcgi
runfastcgi(["method=threaded", "daemonize=false"])
注意你的python目录以及django目录，django工程目录
8. 到/home/twomaom1/django目录下，生成一个工程，叫做code（注意，如果你用python manage.py runserver的方式，最好不要用code做工程的名字，会出错的，似乎是个bug），里面的settings.py配置好mysql
9. 打开浏览器看一下吧，应该差不多了
静态文件设置我试过django自带的、apache alias和Apache rewrite，在开发时使用这种方法还不错。
在bluehost上，我是用的是Apache RewriteRule（见上面的Apache配置），直接把东西放到了t.fcgi所在目录的某个子目录下。
据说Alias也很不错，我试过很多次，每次都是500 Server Internal Error，放弃了
注意：有时候改了文件，想要重启django server，由于fastcgi的预加载，需要做如下尝试：
1. 改变时间戳：touch t.fcgi文件，或者直接打开后强制保存
2. 如果上述方法无效，则尝试把t.fcgi改名，一会儿再改回来
3. 简单粗暴有效果的方法：
用putty连上，打印并过滤python有关的进程：
ps -ef | grep python
在输出中发现这一行：
twomaom1 16445 1982 0 09:41 ? 00:00:00 /home/twomaom1/twomaom1/bin/python t.fcgi
杀之：
kp 16445
我喜欢第三种。
