Nginx访问日志、日志切割、静态文件管理 原

[root@adailinux ~]# vim /usr/local/nginx/conf/nginx.conf
log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
    ' $host "$request_uri" $status'
    ' "$http_referer" "$http_user_agent"';

[root@adailinux ~]# cd /usr/local/nginx/conf/vhost/
[root@adailinux vhost]# ls
aaa.com.conf  test.com.conf

定义test.com.conf日志格式：  
[root@adailinux vhost]# vim test.com.conf  
 ……
 access_log /tmp/test.com.log combined_realip;
    #指定日志位置及格式

检查错误：
[root@adailinux vhost]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@adailinux vhost]# curl -x127.0.0.1:80 test.com
This is test.com
[root@adailinux vhost]# cat /tmp/test.com.log 
127.0.0.1 - [11/Aug/2017:15:09:54 +0800] test.com "/" 200 "-" "curl/7.29.0"

[root@adailinux vhost]# vim /usr/local/sbin/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），确保与虚拟主机配置文件变更保持同步
#该地址来自nginx配置文件
cd $logdir
for log in `ls *.log`
do
    mv $log $log-$d
done
#此处使用通配进行循环，对所有复合条件的日志文件进行切割
/bin/kill -HUP `cat $nginx_pid`
#执行此命令进行重载生成新的日志文件来记录新的日志

[root@adailinux vhost]# sh -x /usr/local/sbin/nginx_log_rotate.sh
++ date -d '-1 day' +%Y%m%d
+ d=20170810
+ logdir=/tmp/
+ nginx_pid=/usr/local/nginx/logs/nginx.pid
+ cd /tmp/
++ ls test.com.log yum.log
+ for log in '`ls *.log`'
+ mv test.com.log test.com.log-20170810
+ for log in '`ls *.log`'
+ mv yum.log yum.log-20170810
++ cat /usr/local/nginx/logs/nginx.pid
+ /bin/kill -HUP 1251

[root@adailinux vhost]# vim test.com.conf
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    #匹配文件类型
    {
          expires      7d;
          #过期时间为7天
          access_log off;
          #不记录该类型文件的访问日志
    }
location ~ .*\.(js|css)$
    {
          expires      12h;
          #过期时间为12小时
          access_log off;
          #不记录该类型文件的访问日志
    }
    access_log /tmp/test.com.log combined_realip;
    #指定日志位置及格式

[root@adailinux vhost]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@adailinux vhost]# /usr/local/nginx/sbin/nginx -s reload

访问index.html：
[root@adailinux vhost]# !curl
curl -x127.0.0.1:80 test.com
This is test.com

[root@adailinux vhost]# !cat
cat /tmp/test.com.log 
127.0.0.1 - [11/Aug/2017:17:45:28 +0800] test.com "/" 200 "-" "curl/7.29.0"
即：有日志！

访问baidu.png文件：
[root@adailinux test.com]# curl -x127.0.0.1:80 test.com/baidu.png -I
HTTP/1.1 200 OK
Server: nginx/1.12.1

说明：max-age=604800s=7天，即该文件缓存的过期时间为7天！

[root@adailinux test.com]# cat /tmp/test.com.log 
127.0.0.1 - [11/Aug/2017:17:45:28 +0800] test.com "/" 200 "-" "curl/7.29.0"
即：无该文件的访问日志！！！
