最佳Nginx日志分割

Nginx日志分割 使用方法（1） 使用定时任务 30 23 * * * cd /home/ccodsupport/nginxLog && sudo ./nginxLog.sh &>/dev/null 修改nginx日志路径 #!/bin/bash # 设置Nginx日志目录 logdir="/home/nginx/logs" # 查找所有日志文件 find "$logdir" -type f -name "*.log" | while read logfile; do # 检查文件是否存在 if [ -f "$logfile" ]; then # 提取日期 date=`date +%F` if [ -z "$date" ]; then echo "Error: cannot extract date from $logfile" continue fi # 创建新日志文件名 newlogfile="$logdir/$(basename "$logfile" .log)_$date.log" # 将日志文件拆分为新文件 cp "$logfile" "$newlogfile" > $logfile fi done 观察日志文件是否分割正常 [nginx@ucloud_nginx_1 logs]$ ls -htrl -rw-r--r-- 1 nginx nginx 380M Apr 18 17:40 error_2023-04-18.log -rw-r--r-- 1 nginx nginx 0 Apr 18 17:40 error.log -rw-r--r-- 1 nginx nginx 55M Apr 18 17:40 access_2023-04-18.log -rw-r--r-- 1 nginx nginx 737K Apr 18 17:40 zabbix_2023-04-18.log -rw-r--r-- 1 nginx nginx 895 Apr 18 17:50 access.log -rw-r--r-- 1 nginx nginx 210 Apr 18 17:50 zabbix.log 使用方法（2） Nginx内部配置设置日志文件格式对应在主配置文件server块中修改 #在nginxhttp块中添加如下配置，如果有多个server配置了不同的日志输出，则在添加对应logdata变量即可 [root@my-dev conf]# vim nginx.conf http { log_format main '$remote_addr - $remote_user [$time_local] "$request" "$request_time" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for" "$upstream_addr" "$upstream_response_time "' ; map $time_iso8601 $logdate { '~^(?<ymd>\d{4}-\d{2}-\d{2})' $ymd; default 'date-not-found'; } access_log logs/access-$logdate.log main; # 需要对应点，该配置项对应添加可访问，错误日志如下报错 [root@my-dev conf]# tail -100f ../logs/error.log 2025/03/02 21:44:04 [crit] 15349#0: *37 open() "/usr/local/nginx/logs/access-2025-03-02.log" failed (13: Permission denied) while logging request, client: 106.37.124.138, server: zhao138969 , request: "GET /actuator/health HTTP/2.0", upstream: "http://39.106.51.232:80/actuator/health", host: "zhao138969 ", referrer: " zhao138969 /console/single-pages/editor?name=72b282df-7b92-422e-b5b8-96ca6649f325" #说明对应log目录没有权限，则需要做以下两种操作： 1、让nginx.conf配置文件配置root用户来启动运行nginx，即可解决。 user root; 2、让其他用户进行运行nginx，然后再其log目录设置属主对应是test用户即可，在reload加载即可。 user test; 看效果 [root@my-dev logs]# ls -htrl total 84K -rw-r--r-- 1 root root 0 Mar 2 21:36 zabbix.log -rw-r--r-- 1 root root 267 Mar 2 21:40 access.log -rw-r--r-- 1 root root 15K Mar 2 21:51 access-2025-03-02.log -rw-r--r-- 1 root root 60K Mar 2 21:53 error.log [root@my-dev logs]# tail -100f access-2025-03-02.log 111.196.247.70 - - [02/Mar/2025:21:54:33 +0800] "GET /apis/content.halo.run/v1alpha1/snapshots/dd78515e-3745-44dc-a255-58f690ed1e38 HTTP/2.0" "0.013" 200 3203 " zhao138969 /console/posts/editor?name=b7ba76fc-6287-46d1-b51e-c22628d84d9f" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36" "-" "127.0.0.1:8090" "0.001 " 111.196.247.70 - - [02/Mar/2025:21:54:48 +0800] "GET /actuator/health HTTP/2.0" "0.008" 403 635 " zhao138969 /console/posts/editor?name=b7ba76fc-6287-46d1-b51e-c22628d84d9f" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36" "-" "39.106.51.232:80" "0.008 "
