实验：部署2048

上传一个2048文件夹到指定目录/home/2048
重新写一个nginx配置文件：

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /home/2048;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

}

}

接着测试配置文件是否正确：(切记一定要使用绝对路径)

[root@VM-244-7-centos ~]# nginx -t -c /home/config2048.conf
nginx: the configuration file /home/config2048.conf syntax is ok
nginx: configuration file /home/config2048.conf test is successful

测试：

可以成功访问。

为Django项目配置nginx文件

静态资源部署

刚刚了解了Nginx如何处理静态文件资源，现在配置Django项目

root需要填写项目所在路径，并且拿到外层，这样可以通用这一个目录
location匹配static静态资源文件，内部需要匹配各种静态资源，这里就可以使用nginx中的alias别名

测试：

可以访问对应的静态文件了。

动态资源部署

动态资源部署需要使用nginx的反向解析到uwsgi服务器上。

我们首先要将settings.py中的DEBUG关闭：

DEBUG = False

安装uwsgi服务器：

pip install uwsgi

在linux上安装报错:

    In file included from plugins/python/python_plugin.c:1:
    plugins/python/uwsgi_python.h:2:10: fatal error: Python.h: No such file or directory
     #include <Python.h>
              ^~~~~~~~~~
    compilation terminated.

原因是缺乏依赖环境，运行：

yum install gcc
yum install python36-devel

然后安装成功。

下面我们配置uwsgi，因为uwsgi默认是没有配置文件，所以需要手动写配置文件：

[uwsgi]
# 使用nginx连接时 使用
# socket=0.0.0.0:8888

# 直接作为web服务器使用
http=0.0.0.0:8888
# 配置工程目录
chdir=/home/PeiQi1

# 配置项目的wsgi目录。相对于工程目录
wsgi-file=PeiQi1/wsgi.py

#配置进程，线程信息
processes=4

threads=10

enable-threads=True
# 主从结构
master=True
# 进程id存储文件
pidfile=uwsgi.pid
# 日志文件
daemonize=uwsgi.log

然后启动uwsgi:

[root@VM-244-7-centos PeiQi1]# uwsgi --ini /var/www/PeiQi1/uwsgi.ini 
[uWSGI] getting INI configuration from /var/www/PeiQi1/uwsgi.ini

可以看到，生成了uwsgi的pid和log文件:

[root@VM-244-7-centos PeiQi1]# ls
alipay_config  App  config.conf  manage.py  middleware  PeiQi1  static  templates  uwsgi.ini  uwsgi.log  uwsgi.pid

查看log文件:
