nginx自定义时间格式

在每个server中加入：

        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;
        }

在log日志格式中修改：

    log_format  main  '$remote_addr - $remote_user [$year-$month-$day $hour:$minutes:$seconds] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
