Class UpdateNginx

java.lang.Object

com.thindeck.agents.UpdateNginx

All Implemented Interfaces:

Agent

public final class UpdateNginx
extends Object
implements Agent

Update nginx load balancer.

Assumption is that ngnix configuration loaded from ngnix.conf and each host has a conf file named www.example.com.conf, which will contain load balancing group, e.g:

 upstream example_servers {
   server 10.0.0.1:80;
   server 10.0.0.2:80;
 }
 server {
   listen 80;
   server_name www.example.com;
   location / {
     proxy_pass http://example_servers;
   }
 }

This file is loaded from main ngnix.conf using include directive.

To install nginx on a clean server, just install it first using "apt-get" or "yum" and that's it.
