    <p>I have 3 computers on same network(LAN). And I want to configure one computer as Nginx Web-Server, and another as Varnish Cache server and one client . I succesfully installed one(let's say A) Nginx ( 192.168.0.15 ) and B Varnish( 192.168.0.20 ). I configured A as a webserver and I can browse the index.html from other computers. But I couldn't connect it with B. I messed up with "nginx.conf" and "/sites-available/server.com" and Varnish's "default.vcl"</p> <p>Could you give me the basic configurations which suit my environment ?</p> <p>If you want to take a look My nginx.conf :</p> <pre><code>http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; upstream dynamic_node { server 1.1.1.1:80; # 1.1.1.1 is the IP of the Dynamic Node } server { listen 81; server_name myserver.myhome.com; location / { #root /var/www/server.com/public_html; #index index.html index.htm; # pass the request on to Varnish proxy_pass http://192.168.0.20; # Pass a bunch of headers to the downstream server. proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_redirect off; } } } </code></pre> <p>/sites-available/server.com :</p> <p>server {</p> <pre><code>listen 80; server_name myserver.myhome.com; access_log /var/www/server.com/access.log; error_log /var/www/server.com/error.log; </code></pre> <p>}</p> <p>And default.vcl like this :</p> <pre><code>backend web1 { .host = "192.168.0.15"; .port = "8080"; } sub vcl_recv { if (req.http.host == "192.168.0.15") { #set req.http.host = "myserver.myhome.com"; set req.backend = web1; } } </code></pre> <p>Lastly /etc/default/varnish :</p> <pre><code>DAEMON_OPTS="-a :6081 \ -T localhost:6082 \ -f /etc/varnish/default.vcl \ -S /etc/varnish/secret \ -s malloc,256m" </code></pre> <p>Thanks in advance :)</p>

    1. COyou can use nginx upstream for backend - which is varnish. Ensure that ip addresses and ports match

    2. COproxy_pass should work too provided varnish is pointing to that ip address/port

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
