Nginx coma reverse proxy

La tòca d'un reverse proxy es de distribuir las requèstas HTTP e HTTPS a mantuns servidors web.

Dins los exemples donats sul malhum Korben info e dins la documentacion de Nginx Nginx reverse proxy, vesèm pas qu'un exemple ont un site unic es partejat en doas partidas.

• per los fichièrs estatics, coma los imatges (ex: /img) ;
• per la partida dinamica del site (ex :*.php).

server {
        listen   80;
        server_name  korben.info;
        access_log  /var/log/korben.access.log;
        error_log  /var/log/korben.nginx_error.log debug;
        location / {
                proxy_pass         http://127.0.0.1:8080/;
        }

        location /phpmyadmin {
                proxy_pass         http://127.0.0.1:8080/phpmyadmin;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
                root   /var/www/nginx-default;
}

Çò que volèm es aver un portal que posquèsse distribuir la carga o las requèstas demest mantuns sites dins cadun sa machina virtuala o sa gabia / jail. Se troba que Nginx es son prètzfach. Doncas per cada machina virtuala avèm un servidor web, apache2.4 o flask o SolR o whatever.
Doncas farem un blòc server per cada site, entresenharem lo(s) blòc(s) location amb .
