Docker 部署Django+Mysql+uWSGI+Nginx Web应用
Change logs更新记录
2022/1/4 fixed web access problem of wide area network（如下）
2021/12 draft notes released
- Docker 启动容器时，将端口 -p 80:80 改为 -p 8001:80（解决外网访问问题, 运营商限制了80端口，所以导致外网访问一直失败，内网访问ok）
- 更新了uwsgi.ini配置文件，更新了nginx配置文件

宿主机上安装Docker
省略…网上有很多教程供参考
创建Mysql容器并启动
简单说明一下， docker run就是运行容器的命令，如果本地仓库没有mysql5.7.19镜像那么docker会自动从docker hub pull 也就是下载我们制定的mysql版本
docker run 参数大白话说明
-d : 后台运行
-v : 卷挂载 本地目录:容器目录
-e : 配置环境（这边我们配置了mysql密码 和 数据库名）
-p : 端口
我的目录
root@HP-ZBook-Fury-17:~/docker/mysql# ls
conf.d data start.shmysql
│ ├── conf.d
│ └── data
│ ├── datacube
│ ├── mysql
│ ├── performance_schema
│ └── sys
文件start.sh
#!/bin/bash
echo "create a mysql container.."
docker run -d --name mysql \-v /root/docker/mysql/conf.d:/etc/mysql/conf.d \-v /root/docker/mysql/data:/var/lib/mysql \-e MYSQL_ROOT_PASSWORD="my-secret-password" \-e MYSQL_DATABASE="datacube" \-p 3306:3306 mysql:5.7.19 \--character-set-server=utf8 --collation-server=utf8_general_ci
文件my.cnf内容
[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
performance_schema = OFF
[mysql]
no-auto-rehash
default-character-set=utf8
到这里就可以运行了
/root/docker/mysql/start.sh
然后docker查看容器已经成功运行

该容器需要与上面创建的mysql容器互联，这里通过更新环境变量的方式来做，因此需要更新django项目下的settings.py 如下:
目录：/root/code/datacube/datacube/settings.py
DATABASES = {'default': {'ENGINE': 'django.db.backends.mysql','NAME': os.environ.get('MYSQL_DATABASE_NAME'),'USER': 'root','PASSWORD': os.environ.get('MYSQL_ENV_MYSQL_ROOT_PASSWORD'),'HOST': os.environ.get('MYSQL_PORT_3306_TCP_ADDR'),'OPTIONS': {"init_command": "SET foreign_key_checks=0;",}}}

3 - 配置nginx.conf (2022/1/4更新)
我的路径：vim /etc/nginx/sites-available/default
root@1ac66f1ccbbd:/# vim /etc/nginx/sites-available/default
upstream django {server 172.17.0.3:8000; # docker 容器ip
}
server {listen 80;server_name 192.168.18.116; #宿主机ipcharset utf-8;access_log /home/docker/code/logs/datacube.access.log;error_log /home/docker/code/logs/datacube.error.log;client_max_body_size 75M;location /media {alias /home/docker/code/datacube/media;}location /static {alias /home/docker/code/datacube/static;}location / {include /etc/nginx/uwsgi_params;uwsgi_pass django;uwsgi_connect_timeout 600;}
}
4 - 查看nginx版本 以及 nginx重载，启动，停止命令
查看版本
root@1ac66f1ccbbd:/# nginx -v
nginx version: nginx/1.14.0 (Ubuntu)重载配置
root@1ac66f1ccbbd:/# service nginx reload* Reloading nginx configuration nginx 启动
root@1ac66f1ccbbd:/# service nginx start* Starting nginx nginx 停止root@1ac66f1ccbbd:/# service nginx stop* Stopping nginx nginx 重启root@1ac66f1ccbbd:/# service nginx restart* Restarting nginx nginx
安装uWSGI 以及常用命令
pip install uwsgi
1 - uwsgi安装使用pip install uwsgi
root@1ac66f1ccbbd:/# pip install uwsgi
Collecting uwsgiDownloading uwsgi-2.0.20.tar.gz (804 kB)|################################| 804 kB 148 kB/sPreparing metadata (setup.py) ... done

Successfully built uwsgi
Installing collected packages: uwsgi
Successfully installed uwsgi-2.0.20
2 - uwsgi.ini 配置文件 (2022/1/4更新)
我的路径：vim /home/docker/code/django-uwsgi-nginx/uwsgi.ini
[uwsgi]
socket = 172.17.0.3:8000 # 和nginx通讯的IP端口，要和nginx保持一致
#sock path
#socket = /home/docker/code/django-uwsgi-nginx/uwsgi.sock
master = true
processes = 4
vacuum = true
buffer-size = 60000
enable-threads = true
chdir = /home/docker/code/datacube
#module = datacube.wsgi
#module = datacube.wsgi:application
chmod-socket = 666
wsgi-file = /home/docker/code/datacube/datacube/wsgi.py
#uwsgi logs path
daemonize = /home/docker/code/logs/uwsgi.log
截止目前，
Docker部署django web项目的所有环境，配置文件，依赖包/软件如：ubuntu18.04, mysql5.7, python, django, nginx, uwsgi以及django项目的的第三方依赖包库均已安装配置完成。，接下来我们开始测试django web 项目 …
进入容器，启动nginx
root@1ac66f1ccbbd:/# service nginx reload* Reloading nginx configuration nginx
启动uwsgi
root@1ac66f1ccbbd:/# vim /home/docker/code/django-uwsgi-nginx/uwsgi.ini
root@1ac66f1ccbbd:/# uwsgi --ini /home/docker/code/django-uwsgi-nginx/uwsgi.ini

端口映射，路由器里面进行配置
我使用的华为路由器，选择 更多功能 – 安全设置 – NAT服务 --端口映射(外网IP映射到服务器IP地址端口如80:80)
游览器输入外网IP地址测试
出现django欢迎页面，恭喜你环境搭建成功，开始上传你的项目吧
以上，希望能帮到你！
附上打赏码请随意，测试一下。哈哈
