nginx를 사용하는 이유

• nginx가 client의 정적 빌드 파일을 실행해주고, 서버와의 proxy 서버 역할을 해준다.

  (서버는 pm2로 함께 띄워놔야함)

• 실행

  systemctl stop nginx
  systemctl start nginx
  
  nginx -s reload //서버를 끄지않고 설정만 리로드
  

• nginx error log

  /var/log/nginx/error.log
  

• myapp.conf

  server {
    listen 80;
    location / {
      root /root/sool/client/build;
      index index.html;
      try_files $uri $uri/ /index.html;
    }
  
    location /api/ {
      proxy_pass <http://localhost:5000>;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection 'upgrade';
      proxy_set_header Host $host;
      proxy_cache_bypass $http_upgrade;
    }
  
    location ~* \\.io {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy false;
  
      proxy_pass <http://localhost:5000>;
      proxy_redirect off;
  
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
    }  
  }
