nginx 直接在配置文章中设置日志分割

直接在nginx配置文件中，配置日志循环，而不需使用logrotate或配置cron任务。需要使用到$time_iso8601 内嵌变量来获取时间。$time_iso8601格式如下：2015-08-07T18:12:02+02:00。然后使用正则表达式来获取所需时间的数据。

按天分割日志

使用下面的代码块

if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})") {
set $year $1;
set $month $2;
set $day $3;
}

access_log /data/logs/nginx/www.ttlsa.com-$year-$month-$day-access.log;

按时、分、秒分割

if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})")
{
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
set $minutes $5;
set $seconds $6;
}
