使用系统自带的logrorate来切个nginx日志，位于/usr/sbin/logrotate
[root@PayServer haproxy]# cat /etc/logrotate.d/nginx /home/nginx/logs/*.log { #指定切割日志文件路径 daily missingok dateext rotate 365 nocompress notifempty olddir /home/nginx/logs/days/ #指定切割后日志存放的位置 create 755 root adm sharedscripts postrotate [ -f /home/nginx/logs/nginx.pid ] && kill -USR1 `cat /home/nginx/logs/nginx.pid` endscript }
- 需要注意的是你们的nginx.pid位置，不一定是在/home/nginx/logs/nginx.pid
| 配置 | 说明 |
|---|---|
| daily | 指定转储周期为每天 |
| weekly | 指定转储周期为每周 |
| monthly | 指定转储周期为每月 |
| rotate | 转储次数，超过将会删除最老的那一个 |
| missingok | 忽略错误，如“日志文件无法找到”的错误提示 |
| dateext | 切换后的日志文件会附加上一个短横线和YYYYMMDD格式的日期 |
| compress | 通过gzip 压缩转储旧的日志 |
| delaycompress | 当前转储的日志文件到下一次转储时才压缩 |
| notifempty | 如果日志文件为空，不执行切割 |
| sharedscripts | 只为整个日志组运行一次的脚本 |
| prerotate/endscript | 在转储以前需要执行的命令可以放入这个对，这两个关键字必须单独成行 |
| postrotate/endscript | 在转储以后需要执行的命令可以放入这个对，这两个关键字必须单独成行 |
执行该命令测试
logrotate -vf /etc/logrotate.d/nginx
