#!/bin/bash
 #设置日志文件存放目录
 logs_path="/var/log/nginx/"
 #设置pid文件
 pid_path="/var/run/nginx.pid"

new_logfile_name=${logs_path}access_$(date -d "yesterday" +"%Y%m%d")

#重命名日志文件
 mv ${logs_path}access.log ${new_logfile_name}.log

#向nginx主进程发信号重新打开日志
 kill -USR1 `cat ${pid_path}`

#压缩文件
 tar -zcf ${new_logfile_name}.tar.gz -C ${new_logfile_name}.log
 #删除文件
 rm -f ${new_logfile_name}.log
