知识相关：

1. 下载nginx： http://nginx.org/en/download.html
2. 编译参数： ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
3. 切割nginx日志脚本

#!/bin/bash
logs_path="/data/logs/nginx/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}wxd5981.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/wxd5981_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`
