MyEMS Web

Introduction

MyEMS Web 用户界面，用于能源数据分析 Providing Web UI for MyEMS users to analysis energy data

Prerequisites

Node.js

nginx-1.18.0 or later

Running in Local environment

This project is scaffolded using Create React App.

• Install Node.js via binary archive on Linux Download Current Linux Binaries (x64) from https://nodejs.org/en/download/current/

Unzip the binary archive to /usr/local/bin/nodejs,

sudo mkdir -p /usr/local/lib/nodejs
sudo tar -xJvf node-v1x.x.x-linux-x64.tar.xz -C /usr/local/lib/nodejs 

Using sudo to symlink node, npm, and npx into /usr/bin/:

sudo ln -s /usr/local/lib/nodejs/node-v1x.x.x-linux-x64/bin/node /usr/bin/node

sudo ln -s /usr/local/lib/nodejs/node-v1x.x.x-linux-x64/bin/npm /usr/bin/npm

sudo ln -s /usr/local/lib/nodejs/node-v1x.x.x-linux-x64/bin/npx /usr/bin/npx

Test installation using

node -v

npm version

npx -v

• Open the “myems/web” directory with your cmd or terminal
• Run 'sudo npm i --unsafe-perm=true --allow-root' This command will download all the necessary dependencies for falcon in the node_modules directory.
• If you modified any scss files, then you need to compile SCSS Run 'sudo npm run scss' command in your project directory to compile scss.
• Run 'sudo npm start' A local web server will start at http://localhost:3000. We are using webpack and webpack-serve to automatically detect file changes. So, if you edit and save a file, your browser will automatically refresh and preview the change.

Creating a Production Build

• Run 'sudo npm run build' command in your project directory to make the Production build.

This will create an optimized production build by compililing, merging and minifying all the source files as necessary and put them in the build/ folder.

You can run 'node server.js' to run the production build locally at http://localhost:5000.

Option 1: Install Production Build on NGINX Server

• Install NGINX Server

refer to http://nginx.org/en/docs/install.html

• Configure NGINX

$ sudo nano /etc/nginx/nginx.conf

In the 'http' section, add some directives:

http{
    client_header_timeout 600;
    client_max_body_size 512M;
    gzip on;
    gzip_min_length 512;
    gzip_proxied any;
    gzip_types *;
    gzip_vary on;
    ...

}

Add a new 'server' section with direstives as below:

  server {
      listen                 80;
      server_name     myems-web;
      location / {
          root    /var/www/html/web;
          index index.html index.htm;
      }
      -- To avoid CORS issue, use Nginx to proxy myems-api to path /api 
      -- Add another location /api in 'server ', replace demo address http://127.0.0.1:8000/ with actual url
      location /api {
          proxy_pass http://127.0.0.1:8000/;
          proxy_connect_timeout 75;
          proxy_read_timeout 600;
          send_timeout 600;
      }
  }

Restart NGINX

$ sudo systemctl restart nginx

• Download myems:

  $ cd ~
  $ git clone https://github.com/MyEMS/myems.git

• Install myems-web :

  Check and change the config file if necessary:

  $ cd ~/myems/web
  $ sudo nano src/config.js

Build and Compress

  $ sudo npm run build
  $ tar czvf myems-web.tar.gz build

Install Upload the file myems-web.tar.gz to you web server. Note that the following path should be same as that was configured in nginx.conf.

  $ tar xzf myems-web.tar.gz
  $ sudo rm -r /var/www/html/web
  $ sudo mv build  /var/www/html/web

Option 2: Install Production Build on Apache2 Server

• Install Apache2 Server

refer to https://httpd.apache.org/docs/2.4/install.html

• Configure Apache2

  $ sudo vi /etc/apache2/ports.conf

Add a Listen

Listen 80

  $ sudo vi /etc/apache2/sites-available/000-default.conf

Add a new 'VirtualHost' as below

<VirtualHost 127.0.0.1:80>
        ServerAdmin MyEMS-web
        DocumentRoot /var/www/web
        
        <Directory "var/www/web">
                Options FollowSymLinks
                AllowOverride All
                Require all granted
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

• Download myems:

  $ cd ~
  $ git clone https://github.com/MyEMS/myems.git

• Install myems-web :

  Check and change the config file if necessary:

  $ cd ~/myems/web
  $ sudo nano src/config.js

Build and Compress

  $ cd ~/myems/web/
  $ sudo npm run build
  $ tar czvf myems-web.tar.gz build

Install Upload the file myems-web.tar.gz to you web server. Note that the following path should be same as that was configured in 000-default.conf

  $ tar xzf myems-web.tar.gz
  $ sudo rm -r /var/www/web
  $ sudo mv build  /var/www/web
