只需要在server配置中，配置一个脚本即可，目前这个是定义了日，可以定义到分。
set多添加几个参数即可

        server {
                listen 80 default_server;
                root "/app/www/public";
                if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})") {
                        set $year $1;
                        set $month $2;
                        set $day $3;
                }
                access_log /app/logs/api-access-$year-$month-$day.log main;
                error_log /app/logs/api-error.log;
                # Php files
                location ~ \.php$ {
                        try_files $uri =404;
                        fastcgi_pass unix:/var/run/php-fpm7.sock;
                }
        }

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;

也可以使用Perl语法来捕获，如下：

if ($time_iso8601 ~ "^(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})") {}
 
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;
}

非常方便的进行日志分割。建议按小时分割日志，方便分析查询日志。
