apache基于mod_wsgi配置Django虚拟主机启动(针对不同端口)

apache基于mod_wsgi配置Django虚拟主机启动(针对不同端口)
(注:CentOS6.2和Windows7都适用)

1. 检查主机名
CentOS:
# hostname
   Windows:
          Doc窗口下执行:hostname

2. 如果主机名不符合要求,修改主机名:
(注:当执行# hostname, 返回的主机名,并不是我们预想的主机名,通俗讲,是我们提供给外网访问的资源地址, 对于局域网,通常使用的是ip访问,所以并不影响局域网)
CentOS6.2下:
步骤一:修改network文件
        # vim /etc/sysconfig/network
         修改HOSTNAME=yourhostname
        参考配置:
        NETWORKING=yes
NETWORKING_IPV6=no
#HOSTNAME=localhost.localdomain
HOSTNAME=yourhostname
步骤二:修改hosts文件
       # vim /etc/hosts
       修改 127.0.0.1 localhost.localdomain localhost
           为 127.0.0.1 localhost.localdomain localhost yourhostname
       参考配置:
           127.0.0.1 localhost.localdomain localhost yourhostname
::1 localhost6.localdomain6 localhost6
步骤三: 重启系统

3. 下载mod_wsgi
下载地址http://code.google.com/p/modwsgi/
注意下载的版本号
   下载后将文件改名为mod_wsgi.so
   并放到apache安装目录的modules目录下
   $APACH_PATH/modules
   例如40机器的目录在:/etc/httpd/modules/

4. 修改apache配置文件
例如40机器是在这里/etc/httpd/conf/httpd.conf
# vim /etc/httpd/conf/httpd.conf
文件末尾添加:
LoadModule wsgi_module modules/mod_wsgi.so
# /usr/bigbang/stargazerservice为应用的路径
Include "/usr/bigbang/stargazerservice/apache_port_django_wsgi.conf"
Include "/usr/bigbang/Unicorn/apache_port_django_wsgi.conf"
5. 进入相应的django应用的目录建立apache需要加载的文件
# cd /usr/bigbang/stargazerservice
# vim apache_port_django_wsgi.conf
文本内容:
Listen 8080
<VirtualHost *:8080>
ServerName data
WSGIScriptAlias / "/usr/bigbang/stargazerservice/django.wsgi"
Alias /site_media/ "/usr/bigbang/stargazerservice/site_media/"

<Directory /site_media>
        Order allow,deny
        Allow from all
</Directory>

<Directory "/usr/bigbang/stargazerservice/apache">
    Order allow,deny
    Allow from all
</Directory>
</VirtualHost>
   还需要新建django.wsgi文件:
   # vim django.wsgi
   文本内容:
   import os, sys

# Calculate the path based on the location of the WSGI script
apache_configuration = os.path.dirname(__file__)
project = os.path.dirname(apache_configuration)
workspace = os.path.dirname(project)
sys.path.append(workspace)

sys.path.append("/usr/bigbang/stargazerservice")      # add to python system path
sys.path.append("/usr/bigbang")             # add to python system path
os.chdir('/usr/bigbang/stargazerservice')
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

同理Unicom这个应用的配置类似,具体的文本为:
apache_port_django_wsgi.conf文本如下:

Listen 8070
<VirtualHost *:8070>
ServerName data
WSGIScriptAlias / "/usr/bigbang/Unicorn/django.wsgi"
Alias /admin_media /usr/lib/python2.6/site-packages/django/contrib/admin/media

<Directory "/usr/bigbang/Unicorn/apache">
    Order allow,deny
    Allow from all
</Directory>
</VirtualHost>

django.wsgi文本内容如下:
import os, sys

# Calculate the path based on the location of the WSGI script
apache_configuration = os.path.dirname(__file__)
project = os.path.dirname(apache_configuration)
workspace = os.path.dirname(project)
sys.path.append(workspace)

sys.path.append("/usr/bigbang/Unicorn")         # add to python system path
sys.path.append("/usr/bigbang")
os.chdir('/usr/bigbang/Unicorn')
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

6. 做完这步后,还需要修改应用的权限,可以让apache访问
# chown –R apache:apache myapplication_path

7. 重启apache
# service httpd restart


还存在的疑惑:
当我使用# /etc/init.d/httpd restart启动apache的时候,发现Unicom使用的环境好像是stargazer留下来的,所以无法访问,# service httpd restart启动一切正常

对应的这次的stargazerservice和unicom的部署,还需要修改相应的项目下的settings.py文件,将其中TEMPLATE_DIRS 处的“'./templates'”用
“os.path.join(os.path.dirname(__file__),'templates').replace('\\','/'),”代替,逗号一定不能忘记。
