手工截取nginx日志与配置自动切割nginx日志的shell脚本【测试成功】

一、问题背景

    nginx在安装时没有配置在自动切割，文件很大，需要查找指定日期的log文件。

二、手工截取

    截取2023-10-18日的日志：

sed -n '/18/Oct/2023/,/19/Oct/2023/p' access.log >20231018.log

或者：

cat access.log_ |egrep "12/Dec/2019" |sed -n '/14:40:00/,/15:36:00/p' >201912.log

二、手工切割每天的日志脚本【加入crontab任务】

    set -e sleep 1 yesterday=$(date -d 'yesterday' +%Y-%m-%d) ng_logs_dir='/home/Yinling/nginx/logs' if [ -d $ng_logs_dir ];then  cd $ng_logs_dir  mv access.log access_${yesterday}.log  kill -USR1 $(cat /home/Yinling/nginx/logs/nginx.pid)  sleep 1 tar -czf access_${yesterday}.log.tar.gz access_${yesterday}.log  rm -f access_${yesterday}.log else  echo "nginx日志目录不存在" exit 0fi
