nginx日志切割

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

reading config file /etc/logrotate.d/nginx
reading config info for /home/nginx/logs/*.log 
olddir is now /home/nginx/logs/days/

Handling 1 logs

rotating pattern: /home/nginx/logs/*.log  forced from command line (365 rotations)
olddir is /home/nginx/logs/days/, empty log files are not rotated, old logs are removed
considering log /home/nginx/logs/access.log
  log does not need rotating
considering log /home/nginx/logs/error.log
  log needs rotating
rotating log /home/nginx/logs/error.log, log->rotateCount is 365
dateext suffix '-20180806'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
glob finding old rotated logs failed
renaming /home/nginx/logs/error.log to /home/nginx/logs/days//error.log-20180806
creating new /home/nginx/logs/error.log mode = 0755 uid = 0 gid = 4
running postrotate script

查看生产的日志文件

每日0点执行脚本

• 在终端运行 crontab -e
• 插入以下语句

0 0 * * * /usr/sbin/logrotate -vf /etc/logrotate.d/nginx
