docker部署nginx下日志自动切割方法实现

docker run -d --name nginx --restart always --net host -v /opt/common/nginx/nginx.conf:/etc/nginx/nginx.conf -v /opt/common/nginx/html:/usr/share/nginx/html -v /opt/common/nginx/logs:/var/log/nginx -v /opt/common/nginx/conf.d:/etc/nginx/conf.d -e TZ="Asia/Shanghai" nginx:1.24.0

map $time_iso8601 $logdate {
    default 'date-not-found';
    '~^(?<ymd>\d{4}-\d{2}-\d{2})' $ymd;
}

access_log  /var/log/nginx/access-$logdate.log  main;

chown -R nginx:nginx logs

#!/bin/bash
LOGS_PATH=$1
DAYS=$2
YESTERDAY=$(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}'`
#删除配置的N天前的日志
cd ${LOGS_PATH}
find . -mtime +${DAYS} -name "*20[1-9][3-9]*" | xargs rm -f
exit 0
