nginx日志按天切割，删除15天日志

cat cut-nginx-log.sh

#delete 15 day nginx log
00 00 * * * /bin/bash /data/script/cut-nginx-log.sh
[root@ali-idn-pro-nginx-ps01 script]# cat /data/script/cut-nginx-log.sh
#!/bin/bash
LOGS_PATH=/data/log/nginx/
YESTERDAY=$(date -d "yesterday" +%Y%m%d)
#按天切割日志
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，重新打开日志文件，否则会继续往mv后的文件写数据的。原因在于：linux系统中，内核是根据文件描述符来找文件的。如果不这样操作导致日志切割失败。
kill -USR1 `ps axu | grep "nginx: master process" | grep -v grep | awk '{print $2}'`
#delete 15 day nginx log
cd ${LOGS_PATH}
find /data/log/nginx/ -type f -mtime +15 | xargs rm -f
exit 0
