Nginx访问日志
log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
' $host "$request_uri" $status'
' "$http_referer" "$http_user_agent"';
combined_realip：日志名称
其余为日志内容
$remote_addr 客户端IP（公网IP）
$http_x_forwarded_for 代理服务器的IP
$time_local 服务器本地时间
$host 访问主机名（域名）
$request_uri 访问的URL地址
$status 状态码
$http_referer referer
$http_user_agent user_agent
[root@centos7 ~]# vim /usr/local/nginx/conf/vhost/test.com.conf
server
{
listen 80;
server_name test.com test2.com test3.com;
index index.html index.htm index.php;
access_log /tmp/test.com.log combined_realip;
验证：
[root@centos7 ~]# tail /tmp/test.com.log
127.0.0.1 - [10/Nov/2017:17:48:20 +0800] test.com "/" 401 "-" "curl/7.29.0"
127.0.0.1 - [10/Nov/2017:17:48:30 +0800] test.com "/index.php" 200 "-" "curl/7.29.0"
Nginx日志切割
日志切割脚本
[root@centos7 shell]# vi nginx_log_rotate.sh
#! /bin/bash
d=`date -d "-1 day" +%Y%m%d`
#定义切割时间（切割一天前的日志）
logdir="/tmp/"
#此处指定要切割的日志路径（该路径来自虚拟主机配置文件）
nginx_pid="/usr/local/nginx/logs/nginx.pid"
#调用pid的目的是执行命令：/bin/kill -HUP `cat $nginx_pid`
#该命令等价于命令：nginx -s reload（重新加载文件)
cd $logdir
for log in `ls *.log`
do
mv $log $log-$d
done
/bin/kill -HUP `cat $nginx_pid`
#执行此命令进行重载生成新的日志文件,与kill -usr1 一样
静态文件不记录日志和过期时间
验证访图片的时候：
[root@centos7 test.com]# curl -x127.0.0.1:80 test.com/baidu.png -I
HTTP/1.1 200 OK
Server: nginx/1.12.1
Date: Fri, 10 Nov 2017 10:01:03 GMT
Content-Type: image/png
[root@centos7 test.com]# curl -x127.0.0.1:80 test.com/index.php
没记录日志
[root@centos7 test.com]# tail /tmp/test.com.log
127.0.0.1 - [10/Nov/2017:17:48:20 +0800] test.com "/" 401 "-" "curl/7.29.0"
127.0.0.1 - [10/Nov/2017:17:48:30 +0800] test.com "/index.php" 200 "-" "curl/7.29.0"
127.0.0.1 - [10/Nov/2017:18:02:38 +0800] test.com "/index.php" 200 "-" "curl/7.29.0"
127.0.0.1 - [10/Nov/2017:18:02:38 +0800] test.com "/index.php" 200 "-" "curl/7.29.0"
问题：curl访问时间不对，但是系统时间是对的？
[root@centos7 test.com]# curl -x127.0.0.1:80 test.com/baidu.png -I
HTTP/1.1 200 OK
Server: nginx/1.12.1
Date: Wed, 15 Nov 2017 02:58:15 GMT
Content-Type: image/png
[root@centos7 test.com]# date
Wed Nov 15 10:58:32 CST 2017
