and network security of this architecture are described as follows:The system architecture only maps ports 80 and 443 of the intranet VIP to the Juniper SSG550 firewall on the Internet. All other ports are disabled, and all intranet machines are disabled; the Internet DNS points to the internet address mapped by Juniper SSG550.Nginx server load balancer generall
Now many domestic large web sites have adopted the Nginx as a Web server, after all, nginx in high concurrency, low resource consumption, reverse proxy, and so has a good performance, now I also with the public, study under the Nginx, by the way load balance.

Competition is the product of today's society, so there is competition everywhere in the online world. In the world of Server Load balancer, nginx and LVS are comparable.

Next, modify vi/etc/httpd/conf/httpd. conf.
Set LogFormat "% h % l % u % t \" % r \ "%> s % B \" % {Referer} I \ "\" % {User-Agent} I \ "" combined
To: logFormat "% {X-Real-IP} I % l % u % t \" % r \ "%> s % B \" % {Referer} I \ "\" % {User-Agent} I \ "" combined
In this way, when accessing the web server, it records not the ip address of the nginx forwarder but the ip address of the user, which is conducive to log analysis
