+一，克隆储存库
+    git clone https://github.com/justdjango/django-ecommerce.git
+    然后按网站上的方法设置虚拟环境，下载requirement，我这里是先安装虚拟环境，再在虚拟环境文件夹内克隆库。
+
+二，更改配置，将django-ecommerce/djecommerce/settings文件夹下的base.py文件中的SECRET_KEY值修改成自己指定的（可以设置为：
+
+`SECRET_KEY = 'abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*(-_=+)'`
+
+然后修改production.py文件的ALLOWED_HOSTS和数据库，改为云数据库，公钥和私钥可以随便找一对写上去。
+
+`ALLOWED_HOSTS = ['*']`
+
+或者*改成外网ip地址or域名，星号表示全都能访问。
+
+将原来的数据库改为云数据库：
+```
+DATABASES = {
+    'default': {
+        'ENGINE': 'django.db.backends.mysql', #使用mysql作为数据库
+        'NAME': 'your database name',
+        'USER': 'your mysql user name',
+        'PASSWORD':'your mysql user password',
+        'HOST':'云数据库ip地址', 
+        'PORT':'3306', #mysql默认端口号
+    }
+}
+```
+
+然后在django-ecommerce文件夹下执行python mange.py collectstatic(若没有文件夹就在django-ecommerce文件夹下创建一个名为static_root的文件夹)
+
+再将djecommerce文件下的wsgi.py更改为
+
+```
+import os
+
+from django.core.wsgi import get_wsgi_application
+
+os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'djecommerce.settings.production')
+
+application = get_wsgi_application()
+```
+
+接下来就是配置nginx和uwsgi
+
+下载nginx和uwsgi
+
+然后配置一个uwsgi的文件，起名叫uwsgi.ini，可以放在django-ecommerce文件夹下新建一个uwsgi_conf文件夹。
+
+里面内容是：
+
+```
+# uwsig使用配置文件启动
+[uwsgi]
+
+# 项目所在的根目录
+chdir=/root/env/django-ecommerce
+
+# 项目中wsgi.py文件的目录，相对于项目目录
+wsgi-file=%(chdir)/djecommerce/wsgi.py
+
+# 设置日志目录
+daemonize=%(chdir)/uwsgi_conf/uwsgi.log
+
+# uWSGI进程号存放
+pidfile=%(chdir)/uwsgi_conf/uwsgi.pid
+
+# 支持ip+port模式以及socket file模式
+#socket=%(chdir)/uwsgi_conf/uwsgi.sock
+socket=127.0.0.1:7777
+
+# 进程个数       
+processes = 4
+
+# 每个进程worker数
+workers=5
+
+# 指定工作进程的线程数
+threads=2
+master=True
+
+# 设置虚拟环境路径
+virtualenv=/root/env
+```
+
+然后在/etc/nginx下找到nginx.conf文件，修改其中内容为：
+
+```

+#    }
+
+}
+```
+
+运行ngixn和uwsgi：
+
+systemctl start nginx.service
+进入/root/CCP/Django-Ecommerce/uwsgi_conf文件夹，启动uwsgi：
+uwsgi --ini uwsgi.ini
+
+访问云主机外网即可访问页面
+
+负载均衡器参照实验六进行添加。
+
+至于前端的一些界面我稍微有些修改，但大体还是一样的。
