CentOS 7.4 + Django2.0 + Python3.6 + gunicorn + nginx + https环境配置

部署环境：

• CentOS 7.4
• Django 2.0.6
• Nginx 1.12.2
• guniron 19.8.1

安装配置django、nginx、guniron

一、django

pip install django==2.0.6

二、nginx

1、安装

yum -y install epel-release
yum -y install nginx

2、启动

systemctl start nginx
systemctl enable nginx

3、修改配置文件

/etc/nginx/nginx.conf

user root root;
worker_processes  auto;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80;
        server_name  localhost;
        root /opt/django-blog;
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
        root   html;
        }

    }
}

/etc/nginx/conf.d/django_site.conf

upstream blog-gunicorn {
    server 127.0.0.1:8000 fail_timeout=0;
}
# 将未加密的流量重定向到加密的网站
server {
    listen       80;
    server_name  site.com;
    return      301 https://$server_name$request_uri;
}
# 主服务块
server {
    # 设置监听的端口，指定监听的域名
    listen 443 default ssl;
    client_max_body_size 4G;
    server_name site.com;
    # 指定日志位置
    access_log /var/log/nginx/blog.access_log;
    error_log /var/log/nginx/blog.error_log;
    # 告诉 nginx 你的 ssl 证书
    ssl on;
    ssl_certificate /etc/nginx/ssl/1_site.com_bundle.crt;
    ssl_certificate_key /etc/nginx/ssl/2_site.com.key;
    ssl_session_timeout 5m;
    ssl_protocols SSLv2 SSLv3 TLSv1;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;
    # 设置根目录
    root /opt/django-blog;
    # 为 Nginx 指定静态文件路径
    location /static/ {
        # Autoindex the files to make them browsable if you want
        autoindex on;
        # The location of your files
        alias /opt/django-blog/static/;
        # Set up caching for your static files
        expires 1M;
        access_log off;
        add_header Cache-Control "public";
        proxy_ignore_headers "Set-Cookie";
    }
    # 为 Nginx 指定你上传文件的路径
    location /media/ {
        autoindex on;
        # The location of your uploaded files
        alias /opt/django-blog/media/;
        # Set up aching for your uploaded files
        expires 1M;
        access_log off;
        add_header Cache-Control "public";
        proxy_ignore_headers "Set-Cookie";
    }
    location / {
        # Try your static files first, then redirect to Gunicorn
        try_files $uri @proxy_to_app;
    }

    location @proxy_to_app {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect ~^http://([^:]+)(:\d+)?(.*)$  https://$1$3;
        proxy_pass  http://127.0.0.1:8000;
    }
}

4、重载配置

systemctl reload nginx

三、安装gunicorn

pip insatll gunicorn

安装好之后，可以创建django项目根目录创建 gunicorn-conf.py

import multiprocessing
bind = "0.0.0.0:8000"
workers = 2
workers = multiprocessing.cpu_count() * 2 + 1
errorlog = "/opt/django-blog/gunicorn.error.log"
#loglevel = "debug"
proc_name = "gunicorn_blog"
reload = True
daemon = True

然后再项目根目录下之下一下命令：

gunicorn -c gunicorn-conf.py -D --error-logfile /项目根目录/gunicorn-error.log 项目名.wsgi

重启nginx：

systemctl reload nginx

然后访问：

https://site.com

四、安装supervisor，需要用python2进行安装，python3不支持（可选安装）

yum -y install supervisor
git clone 
cd supervisor/
python2 setup.py install

在/etc/supervisord.conf末尾根据自己的项目加入配置项，以下为例子：

[program:django_blog]
command=/usr/bin/gunicorn -c /opt/django-blog/gunicorn.conf django_blog.wsgi:application
directory=//opt/django-blog
autostart=true
autorestart=true
stdout_logfile=/opt/django-blog/logs/gunicorn.log
stderr_logfile=/opt/django-blog/logs/gunicorn.err

启动supervirsor：

supervisord -c /etc/supervisord.conf
