Nginx 负载均衡在金山逍遥网中的实际应用

在金山逍遥网中，前端负载均衡服务器采用的是Nginx，两台Nginx服务器为一组，承担多种类型的负载均衡服务，两台负载均衡服务器均处于活动状态，各自绑定一个公网虚拟IP，作为负载均衡服务器，当其中一个发生故障时，另一台接管发生故障服务器的虚拟IP。配置nginx.conf代码如下

代码：

user www www;
work_processes 8;
error_log /data1/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;

#specifies the value for maximum file descriptors that can be opened by this process worker_rlimit_nofile 51200
