[nginx load balance by full client ip] #nginx #linux

   upstream apachereadonly  {
     server 10.10.11.10:8011; 
     server 10.10.11.11:8011; 
     server 10.10.11.12:8011; 
	 hash $remote_addr consistent;
   }

Please note the ip_hash of nginx only cares the first thress parts of client ip, so 10.0.0.1/24 all will go to the same backend server.
