一个nginx切割日志的脚本，自动删除7天前日志

#!/bin/bash
LOGS_PATH=/home/wwwlogs
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)

按天切割日志

mv ${LOGS_PATH}/access.log ${LOGS_PATH}/access_${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后的文件写内容，导致切割失败.

kill -USR1 ps axu | grep "nginx: master process" | grep -v grep | awk '{print $2}'

压缩

gzip -9 ${LOGS_PATH}/access_${YESTERDAY}.log

删除7天前的日志

cd ${LOGS_PATH}
find . -mtime +7 -name "201-9" | xargs rm -f
exit 0

kill -USR1 ps aux | grep "nginx: master process" | grep -v grep | awk '{print $2}'

kill -USR1 cat /usr/local/nginx/logs/nginx.pid
