The project is the complete separation of the front and rear desks , The front desk address is http:// domain name :80 port , backstage api The interface address is :http:// domain name :7001,websocket The communication interface is ：ws:// domain name :7002

One , Database import

After creating a new database and importing data , Discover remote navicat Unable to connect , Tips Lost connection to MySQL server at reading initial communication packet

solve ： Set the database permissions so that everyone can access ( Only remote navicat During connection test , You can narrow the permission later )

Two , How to add python Of django project ？

Method ： Using the pagoda python Project manager

  Be careful ： Pagoda only supports in centOS7+ Use , I wanted to use ubuntu, It can only be converted to centos 了 , But the difference is not big .

Pit point ： Be sure not to choose 2.0 edition , choice 1.9 edition . I installed 2.0 I think the new version must be more powerful , It turned out that there was no pvenv command , The command is that the Baoda panel is installed python Project manager post configuration python Environmental , Provides a lot of convenient instructions

After installation, click the settings , Because the version I developed is higher ,centos The built-in python2.* no way ,（ Mainly channel Need to have 3.4 Version above is supported async And so on ） So you need to install it first python3.* Version above , Here I installed j yes 3.8.3 edition

Enter from the pagoda panel to the terminal , Now you can use pyenv The command , Use pyenv versions View the current by python Project manager installed python All versions , Use pyenv shell Version number Command to modify the default python edition , Pictured

  Before that daphne The service , Always prompt for grammatical errors , Observe the error prompt and find that you don't know async keyword , So it has to be in python3.4+ Start in environment daphne, So the above settings are essential for me .

Upload the rest first python The whole content of the project , I installed it through the pagoda panel ftp Post upload , No use of pagoda file management  . Upload it in python Add project to project manager , The specific configuration is as follows ：

  Upload with generated requuirements.txt, And check the installation dependency , The virtual environment can be automatically configured and started , At this time, the project shows that it is running , It means that it has succeeded , Otherwise, you can view the log or enter the virtual environment （ The method of entering the virtual environment is shown in the figure ） Start to view error messages .

Then I went through xshell The remote is turned on daphne service

  3、 ... and 、 Configure the website

Although the project has a default 80 Port as front-end website ,7001 Port to do webAPI The server ,7002 Port to do websocket Receive and forward service （ Forwarding to daphne namely 127.0.0.1:7003）, and daphne Service running on 7003 port , But you only need to configure one website ( I wanted to create it separately , However, after trying, it seems that only one website can be created for a domain name )

  In the configuration file , My default will be 80 Configure as foreground website path ,7002 Forwarding by proxy , and 7001 Port by phython Project management has access to （ There are some questions here , stay python I didn't specify the domain name in the project management , Only the port is specified , But the front desk can really use the domain name :7001 Visit ）, The details are as follows ：

server
{
    listen 80;
    server_name www.youhostname.cn;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/ftpFrontUser/platform/platform/frontEnd/EXP_platform/myserver;

    include enable-php-00.conf;

    include /www/server/panel/vhost/rewrite/www.youhostname.cn.conf;
    #REWRITE-END
    
    # Forbidden files or directories 
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
    }
    
    # One click application SSL Certificate validation directory related settings 
    location ~ \.well-known{
        allow all;
    }
    
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
        error_log /dev/null;
        access_log /dev/null;
    }
    
    location ~ .*\.(js|css)?$
    {
        expires      12h;
        error_log /dev/null;
        access_log /dev/null; 
    }
    access_log  /www/wwwlogs/www.youhostname.cn.log;
    error_log  /www/wwwlogs/www.youhostname.cn.error.log;
}

server {
        listen       7002;
        server_name  www.youhostname.cn;

          location /ws{#ws
            proxy_http_version 1.1;
            proxy_set_header Host  $host;
            proxy_set_header X-Real-Ip $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Nginx-Proxy true;
            proxy_redirect off;
            client_max_body_size 10m;
            proxy_pass http://127.0.0.1:7003;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_connect_timeout 300s;
            proxy_read_timeout 300s;
            proxy_send_timeout 300s; 
       }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    
    }

The front page starts , It can be found that the interface can access , The front and rear ends have been opened . however websocket Communication is not yet available . Start below daphne service ：

daphne -p 7003  Project name .asgi:application

But when ssh After the remote connection window closes , The service stops automatically , So here we use nohup command

nohup daphne -p 7003  Project name .asgi:application > /dev/null 2> /dev/null &

Turn off the ssh window ,websocket Communication is working properly ！
