实例


log_format  gzip  '$remote_addr - $remote_user [$time_local]  '

access_log  /spool/logs/nginx-access.log  gzip  buffer=32k;

指令


access_log

语法: access_log path [format [buffer=size | off ] 默认值: access_log log/access.log combined

作用域: http, server, location

指令 access_log 指派路径、格式和缓存大小。参数 "off" 将清除当前级别的所有 access_log 指令。如果未指定格式,则使用预置的 "combined" 格式。缓存不能大于能写入磁盘的文件的最大大小。在 FreeBSD 3.0-6.0 ,缓存大小无此限制。


log_format

语法: log_format name format [format ...]

默认值: log_format combined "..."

作用域: http server

Directive log_format describes the format of a log entry. Besides general variables in the format it is possible to use variables which exist only at the moment of record into the log:

The headers, transmitted to client, begin from the prefix "sent_http_", for example, $sent_http_content_range.

In the configuration there is always a predetermined format "combined":


log_format  combined  '$remote_addr - $remote_user [$time_local]  '
: '"$request" $status $apache_bytes_sent '
: '"$http_referer" "$http_user_agent"';
