# Nginx

## Port Forwarding

1. install nginx

sudo apt install nginx -y

2. delete default configuration file

sudo rm /etc/nginx/sites-enabled/default

3. add our own configuration file

sudo vim /etc/nginx/sites-available/cms_nginx

server {
    listen 80;
   
    location / {
        proxy_pass http://localhost:8888;
    }

    location /admin/ {
        rewrite ^/admin/(.*) /$1 break;
        proxy_pass http://localhost:8889;
    }
    
    location /ranking/ {
        rewrite ^/ranking/(.*) /$1 break;
        proxy_pass http://localhost:8890;
    }
}

4. create link

sudo ln -s /etc/nginx/sites-available/cms_nginx /etc/nginx/sites-enabled/

5. test configuration

sudo nginx -t

6. restart nginx

sudo service nginx restart

### Fix Record
#### 413 Request Entity Too Large
在`/etc/nginx/nginx.conf`檔案中找到http段落，加入以下限制

client_max_body_size 100m;

## Web Server

server {
   listen 8080;

   root /var/www/html;

   index index.html;

   location / {
       try_files $uri $uri/ =404;
   }
}

如果要改 root directory 的位置，要確保該路徑中的每個資料夾都有`+x`權限，像是

root /home/contest/website;

要有

sudo chmod +x /home
sudo chmod +x /home/contest

## Others

possible path of configuration file
`/usr/local/etc/nginx/nginx.conf`
`/etc/nginx/nginx.conf`

events {
    worker_connections  1024;
}

http {
    server {
        listen 80;
        server_name erichung.sa;

        location / {
            proxy_pass http://localhost:8000;
        }
    }
}
