Step 1: Change the source

Enter the command to replace the Ubuntu download source

sudo nano /etc/apt/sources.list

Copy after login

Replace all the following with the original file, What I use here is Alibaba’s source, you can also change it to other sources.

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted
deb http://mirrors.aliyun.com/ubuntu/ bionic universe
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates universe
deb http://mirrors.aliyun.com/ubuntu/ bionic multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted
deb http://mirrors.aliyun.com/ubuntu/ bionic-security universe
deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu bionic stable

Copy after login

分别输入以下命令，更新源
sudo apt update
sudo apt upgrade

Copy after login

Step 2: Install related packages

1. Install python3

# 安装python3
sudo apt install python3
# 查看python安装路径：
which python
# 查看python版本：建议使用3.6之后的版本，因为其他的笔者没试过，笔者用的是3.6.9版本
python

Copy after login

2. Install openssh-server and net-tools

# 安装 openssh-server
sudo apt install openssh-server
#开启：
sudo service ssh start
 
# 安装net-tools  
sudo apt install net-tools
# 查看虚拟机ip:
ifconfig

Copy after login

as shown below As shown, it is our virtual machine IP

How to deploy your own django project with nginx+uwsgi

Install the running environment of django

#安装django运行环境：
sudo apt install virtualenv
# 创建环境
virtualenv --python=/usr/bin/python3 myblog
# 进入环境：
cd myblog
# 激活环境：
source bin/activate

Copy after login

Install django:pip3 install Django

Create project:django-admin.py startproject blog

After activating and creating the project, it will basically look like the picture below

How to deploy your own django project with nginx+uwsgi

# 进入到blog中安装 uwsgi：
pip3 install uwsgi

Copy after login

Step 3: Write a test file and test run

1. Write a test file

After installation, we will write a test file to test us The way the project is run is the same as the actual project. Here I use the nano editing and writing method. You can also use vim. The method is not limited. If you can create and write, you can write the command:

sudo nano test.py

Required The written file content is:

def application(env,start_response):
        start_response('200 ok',[('Content-Type','text/html')])
        return [b"Hello World"]

Copy after login

2. Test run

The test command is: uwsgi --http :8000 --wsgi-file test.py

After pressing Enter, we enter the IP and port number in the browser. Mine is 192.168.217.133:8000. When I opened it in the browser, I found the following error.

How to deploy your own django project with nginx+uwsgi

For this error, we only need to open the settings.py file of the project file, add the address of our virtual machine in ALLOWED_HOSTS, and it will be ok, and then we will test and run , found to be normal, the web page outputs hello world. This shows that uwsgi can run the test file normally.

How to deploy your own django project with nginx+uwsgi

But we are not running the test.py file, we are running our own django project. Here we need to modify the previous command to: uwsgi - -http :8000 --module blog.wsgi

Step 4: Introduce nginx

1. Install and start nginx

In order to avoid not entering the port number when entering the ip It can also be used normally. We introduce lightweight nginx. Here we use the command line to install and start nginx

Installation: sudo apt install nginx

Start: sudo service nginx start

2. Write the conf configuration file

Enter the command: sudo nano /etc/nginx/sites-available/blog_nginx.conf

Create a new conf file and write the following content. Change all the paths involved in it to the path of your own project:

upstream django {
    # server unix:///home/python/myblog/blog/blog.sock; # 这里的路径改为你自己项目路径
    server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}
server {
    listen      8000;
    server_name 192.168.217.133; # 将这里的ip地址改为你自己的虚拟机或者服务器地址
    charset     utf-8;
    client_max_body_size 75M;   # adjust to taste
    location /media  {
        alias /home/python/myblog/blog/media;  # your Django project's media files - amend as required
    }
    location /static {
        alias /home/python/myblog/blog/static; # your Django project's static files - amend as required
    }
    location / {
        uwsgi_pass  django;
        include     /home/python/myblog/blog/uwsgi_params; # the uwsgi_params file you installed
    }
}

Copy after login

After creating the file, we need to create the file A soft link, you need to enter the following command:

sudo ln -s /etc/nginx/sites-available/blog_nginx.conf /etc/nginx/sites-enabled

After completion, we can use the command ll /etc/nginx/sites-enabled/ to check whether the settings are correct. Refer to the figure below

How to deploy your own django project with nginx+uwsgi

##3. Create the uwsgi_params file and Static folder configuration

1), uwsgi_params

Here we need to create a uwsgi_params file, the creation command is:

sudo nano uwsgi_params

and add the following Write the content verbatim into the uwsgi_params file, save and exit

uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;
uwsgi_param  CONTENT_LENGTH     $content_length;
uwsgi_param  REQUEST_URI        $request_uri;
uwsgi_param  PATH_INFO          $document_uri;
uwsgi_param  DOCUMENT_ROOT      $document_root;
uwsgi_param  SERVER_PROTOCOL    $server_protocol;
uwsgi_param  REQUEST_SCHEME     $scheme;
uwsgi_param  HTTPS              $https if_not_empty;
uwsgi_param  REMOTE_ADDR        $remote_addr;
uwsgi_param  REMOTE_PORT        $remote_port;
uwsgi_param  SERVER_PORT        $server_port;
uwsgi_param  SERVER_NAME        $server_name;

Copy after login

After saving the file, restart nginx

2), create a static folder

Open In the settings.py file of the django project, add the path of the static file, as shown below:

How to deploy your own django project with nginx+uwsgi

Then save and exit and copy the mapped static file, the command is:

python manage. py collectstatic

Create the media folder:

mkdir media

Finally enter the command to check whether the static folder is configured correctly:

Step 5: Establish pipeline communication between uwsgi and nginx

Change http communication to socket communication in uwsgi, modify the command to: uwsgi --socket :8001 --wsgi-file test .py

Enter blocking at this time, enter the IP address: 192.168.217.133:8000 in the browser, and find that it can be opened, showing hello world successfully. It means that the communication between uesgi and nginx is normal

Enter the nginx configuration file: sudo nano /etc/nginx/sites-available/blog_nginx.conf

Comment the second line of the following two lines in the file Off, open the first line, but the path must be correct, use pipe communication instead

server unix:///home/python/myblog/blog.sock; # for a file socket
# server 127.0.0.1:8001; # for a web port socket (we'll use this first)

保存退出，重启nginx：sudo service nginx restart

将uwsgi参数套节字改为blog.sock

uwsgi --socket blog.sock --wsgi-file test.py

回到浏览器输入:192.168.217.133:8000得到502：如图

How to deploy your own django project with nginx+uwsgi

我们查看一下错误日志，发现是因为权限问题，解决办法，在命令行后面加入--chmod=666

uwsgi --socket blog.sock --wsgi-file test.py --chmod=666

运行之后发现没有问题，并且正常显示Hello World界面。

现在我们运行django项目，命令为：uwsgi --socket blog.sock --module blog.wsgi --chmod=666

刷新192.168.217.133：8000得到django的基础页面。

目前可以说明nginx和uwsgi管道通信正常。

第六步：将项目改为后台运行

创建一个uwsgi的配置文件：sudo nano blog_uwsgi.ini

写入一下内容，将其中的路径改为自己的项目路径

# mysite_uwsgi.ini file
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir = /home/python/myblog/blog
# Django's wsgi file
module = blog.wsgi
# the virtualenv (full path)
home = /home/python/myblog
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 10
# the socket (use the full path to be safe
socket = /home/python/myblog/blog/mysite.sock
# ... with appropriate permissions - may be needed
chmod-socket = 664
# clear environment on exit
vacuum = true
# daemonize uwsgi and write messages into given log
daemonize = /home/python/myblog/blog/uwsgi.log

Copy after login

保存退出并且启动配置文件，命令为：uwsgi --ini blog_uwsgi.ini

我们可以查看一下后台进程，是否正常启动，输入：ps aux

最后回到nginx配置文件中，将监听端口改为80，重启nginx即可。在浏览器中输192.168.217.133得到django页面结果，表示项目运行正常。
