Simple Nginx server load balancer configuration example

The domain names www.s135.com & nbsp; and blog.s135.com both point to the IP address of the Nginx server. The user access the http://www.s135.com, load balancing its 192.168.1.2: 80, 192.168.1.3: 80, 192.168.1.4: 80, 192.168.1.5: 80 four servers. Use

Www.s135.com? And blog.s135.com domain names all point to the IP address of the Nginx server.

The user access the http://www.s135.com, load balancing its 192.168.1.2: 80, 192.168.1.3: 80, 192.168.1.4: 80, 192.168.1.5: 80 four servers.

The user accesses the http://blog.s135.com and balances its load to ports 8080, 8081, and 8082 of the 192.168.1.7 server.

The configuration file nginx. conf is as follows:

User? Www; worker_processes 10; # error_log? Logs/error. log; # error_log? Logs/error. log? Notice; # error_log? Logs/error. log? Info; # pid???? Logs/nginx. pid; # Maximum file descriptor worker_rlimit_nofile 51200; events {use epoll; worker_connections 51200;} http {include??? Conf/mime. types; default_type?

Appendix: for Nginx installation method, refer to Nginx 0.5.31 + PHP 5.2.4 (FastCGI) to set up a connection that can withstand more than 30 thousand concurrent connections, the following section is better than Apache's 10-fold Web server article (Load Balancing only, without the need to support PHP installation ):

II. install PHP 5.2.4 (FastCGI mode)
4. create www users and groups and their directories:

3. install Nginx 0.5.31
1. install the pcre library required by Nginx:
2. install Nginx
3. create an Nginx log Directory
5. start Nginx
