nginx日志切割脚本,自动压缩

#nginx日志切割脚本

#!/bin/bash
#设置日志文件存放目录
logs_path="/usr/local/nginx/logs/"
#设置pid文件
pid_path="/usr/local/nginx/logs/nginx.pid"

date_str=access_$(date -d "yesterday" +"%Y%m%d")

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

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

#压缩日志
tar -zcf ${logs_path}${date_str}.tar.gz ${logs_path}${date_str}.log
rm -f ${logs_path}${date_str}.log
