如何设置访问日志格式

nginx.conf
http{
       log_format  **access  **' [$time_local] | $host |  $remote_addr |  $request | $request_time |  $body_bytes_sent  |  $status |'
                            '| $upstream_addr | $upstream_response_time  |  $upstream_status  |'
                            ' "$http_referer"  | "$http_user_agent" ';

	access_log /var/log/nginx/access.log **access**;
	error_log /var/log/nginx/error.log;
}

 [18/Feb/2021:11:02:34 +0800] | 10.21.138.90 |  10.24.71.124 |  GET /pdf/trans?id=3282442&insertTime=2021-02-18&source=em_pc&type=61173529492151d1577adf5e37c099.pdf HTTP/1.1 | 0.798 |  63  |  200 || 127.0.0.1:9056 | 0.798  |  200  | "-"  | "Apache-HttpClient/4.5.2 (Java/1.8.0_102)"

日志格式介绍

$upstream_connect_time – The time spent on establishing a connection with an upstream server
$upstream_header_time – The time between establishing a connection and receiving the first byte of the response header from the upstream server
$upstream_response_time – The time between establishing a connection and receiving the last byte of the response body from the upstream server
$request_time – The total time spent processing a request

注意点

http{
   access_log /var/log/nginx/access.log **access**;
}
指定access_log文件存放目录，也需要指定类型“access”（在http->log_format 定义的）
