Django+gunicorn+nginx项目部署

  通过gunicorn部署django项目，比使用uwsgi方式要简单，具体操作如下：

  步骤：

 1. 安装依赖

yum install python3
yum install nginx （或者下载nginx包部署）
yum install gunicorn
pip install gevent   # 这个是gunicorn运行的一种模式
easy_install -U greenlet
easy_install -U eventlet
pip install gevent

2. 检查python/nginx安装是否成功

     a. 输入python3，是否出现交互命令页面

      

     b. 启动nginx, 浏览器访问ip，出现weclome ngix

举例：

 启动nginx:        ./nginx

2种方式验证nginx是否启动/安装成功：

     进程查看： ps -ef |grep nginx 

     页面访问：  

     

 3. gunicorn 简单使用

    按照上面的例子,当前目录为 /home/myapp, myapp中有一个包 gunicorn_app，gunicorn_app.py代码如下：

def app(environ, start_response):
    data = b"Hello, World!\n"
    start_response("200 OK", [("Content-Type", "text/plain"),("Content-Length", str(len(data)))])
    return iter([data])

我们将要运行 test.py文件中的 app(当然名字由你决定,可以是myapp,demo等等)

       gunicorn -w 2 gunicorn_app:app

    

 上图展示了两个很重要的信息：

　　第一：启动了两个worker，这是通过"-w 2"指定（默认为1）

　　第二：worker的工作模型是sync（默认），后面会详细介绍worker模型

 

 

 

Django项目部署

      项目结构：

      

    1. 上传django项目到 /data/service目录下，在 /data/service/Django_project目录下 创建 static目录

    2. 配置nginx文件， /usr/local/nginx/conf/nginx.conf
