I installed apache2 and now I wont use nginx now. I could reached my html page on local network on 192.168.1.11.The html file is saved in  var/www/html/index.html. Now I installed nginx. I try to uninstall apache by these commands:sudo apt-get --purge remove apache2sudo apt-get autoremovesudo rm -r apache2I thought, now is my apache server uninstalled but when I reach 192.168.1.11 I reach my old html page saved in /var/www/html/. I googled that nginx default public www location is /usr/share/nginx/html/. My questions:Why do I reach the html created for apache?How can I be sure I uninstalled all apache packages, directories etc.?Can I just delete the www directory in /var/ ?How can I reach the html page saved in nginx default public www location?sudo lsof -i:443nginx 543 root 7u IPv4 9117 0t0 TCP *:https(LISTEN)nginx 544 www-data 7u IPv4 9117 0t0 TCP *:https (LISTEN)nginx 545 www-data 7u IPv4 9117 0t0 TCP *:https (LISTEN)nginx 548 www-data 7u IPv4 9117 0t0 TCP *:https (LISTEN)nginx 549 www-data 7u IPv4 9117 0t0 TCP *:https (LISTEN)sudo lsof -i:80nginx 543 root 6u IPv4 9116 0t0 TCP *:http(LISTEN)nginx 544 www-data 6u IPv4 9116 0t0 TCP *:http (LISTEN)nginx 545 www-data 6u IPv4 9116 0t0 TCP *:http (LISTEN)nginx 548 www-data 6u IPv4 9116 0t0 TCP *:http (LISTEN)nginx 549 www-data 6u IPv4 9116 0t0 TCP *:http (LISTEN)  Configuration:upstream php-handler {      server 127.0.0.1:9000;      #server unix:/var/run/php5-fpm.sock;  }  server {      listen 80 ;      server_name 192.168.1.11;      return 301 https://$server_name$request_uri;  # enforce https  }  server {      listen 443 ssl;      server_name 192.168.1.11;      ssl_certificate /etc/nginx/cert.pem;      ssl_certificate_key /etc/nginx/cert.key;      # Path to the root of your installation      root /var/www/owncloud;      client_max_body_size 1000M; # set max upload size      fastcgi_buffers 64 4K;      rewrite ^/caldav(.*)$ /remote.php/caldav$1 redirect;      rewrite ^/carddav(.*)$ /remote.php/carddav$1 redirect;      rewrite ^/webdav(.*)$ /remote.php/webdav$1 redirect;      index index.php;      error_page 403 /core/templates/403.php;      error_page 404 /core/templates/404.php;      location = /robots.txt {          allow all;          log_not_found off;          access_log off;      }      location ~ ^/(?:\.htaccess|data|config|db_structure\.xml|README) {          deny all;      }      location / {          # The following 2 rules are only needed with webfinger          rewrite ^/.well-known/host-meta /public.php?service=host-meta last;          rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last;          rewrite ^/.well-known/carddav /remote.php/carddav/ redirect;          rewrite ^/.well-known/caldav /remote.php/caldav/ redirect;          rewrite ^(/core/doc/[^\/]+/)$ $1/index.html;          try_files $uri $uri/ index.php;      }      location ~ \.php(?:$|/) {          fastcgi_split_path_info ^(.+\.php)(/.+)$;          include fastcgi_params;          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;          fastcgi_param PATH_INFO $fastcgi_path_info;          fastcgi_param HTTPS on;          fastcgi_pass php-handler;     }     # Optional: set long EXPIRES header on static assets     location ~* \.(?:jpg|jpeg|gif|bmp|ico|png|css|js|swf)$ {          expires 30d;          # Optional: Don't log access to assets          access_log off;     }  }
