虽然说windows上的nginx在官方文档中提到“仅作为测试”之用，但对于小规模并发场景还是比apache有不小的优势。所以，本文也将其作为windows服务器上负载均衡的主要工具进行说明。

#指定nginx进程数，通常与CPU数相一致。特别是在windows平台中，这一数值一般只能设置为1。
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
# windows平台基本只能设置为1024
worker_connections 1024;
}
