nginx自动切割日志

#!/bin/bash
#Rotate the Nginx logs to prevent a single logfile from consuming too much disk space. 
LOGS_PATH=/usr/local/nginx/logs
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)
mv ${LOGS_PATH}/access.log ${LOGS_PATH}/access_${YESTERDAY}.log
mv ${LOGS_PATH}/error.log ${LOGS_PATH}/error_${YESTERDAY}.log
## 向 Nginx 主进程发送 USR1 信号。USR1 信号是重新打开日志文件
kill -USR1 $(cat /usr/local/nginx/logs/nginx.pid)
           

vi /etc/crontab

* * * root /usr/local/nginx/logs/nginxLogRotate.sh
