Node.js 配置

1. 安装nodejs

  sudo apt install nodejs

2. 修改server.js配置文件，包括域名或者ip地址，还有np路径。

3. 设置node-server.service

   cat /etc/systemd/system/node-server.service 
   
   [Unit]
   Description=Node.js Server (server.js)
   After=network.target
   
   [Service]
   WorkingDirectory=/home/admin/your path folder
   ExecStart=/usr/bin/node /your path folder/server.js
   Restart=always
   User=admin
   Group=admin
   Environment=NODE_ENV=production
   Environment=PATH=/usr/bin:/usr/local/bin
   
   [Install]
   WantedBy=multi-user.target

4. 拷贝node-server.service 到 /etc/systemd/system/

   sudo systemctl enable node-server.service
   sudo systemctl start node-server.service
