Nginx访问日志、日志切割、静态文件不记录日志和过期时间

12.10 Nginx访问日志

  • 日志格式
#搜索log_format
[root@taoyuan ~]# vim /usr/local/nginx/conf/nginx.conf

* 这里的combined_realip就是在nginx.conf中定义的日志格式名字

参数 含义
$remot_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
  • 除了在主配置文件nginx.conf里定义日志格式外,还需要在虚拟主机配置文件中增加如下的参数
[root@taoyuan ~]# vim /usr/local/nginx/conf/vhost/test.com.conf

注:taoyuan为日志格式的名字

  • access_log/tmp/1.log combined_realip;
  • -t && -s reload
[root@taoyuan ~]# /usr/local/nginx/sbin/nginx -t
nginx: [emerg] unknown log format "taoyuan" in /usr/local/nginx/conf/vhost/test.com.conf:10
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed
[root@taoyuan ~]# /usr/local/nginx/sbin/nginx -s reload
nginx: [emerg] unknown log format "taoyuan" in /usr/local/nginx/conf/vhost/test.com.conf:10
  • curl -x127.0.0.1:80 test.com -I

  • 查看日志
[root@taoyuan ~]# cat /tmp/test.com.log 
127.0.0.1 - [04/Jan/2018:21:23:02 +0800] test3.com "/admin/index.html" 301 "-" "curl/7.29.0"
127.0.0.1 - [04/Jan/2018:21:23:10 +0800] test2.com "/admin/index.html" 301 "-" "curl/7.29.0"

12.11 Nginx日志切割

  • 自定义shell日志切割脚本
#创建shell脚本
[root@taoyuan ~]# vim /usr/local/sbin/nginx_log_rotate.sh

#写入如下的内容
#!/bin/bash
d=`date -d "-1 day" +%Y%m%d`
logdir="/tmp/"
nginx_pid="/usr/local/nginx/logs/nginx.pid"
cd $logdir
for log in `ls *.log`
do
     mv $log $log-$d
done
/bin/kill -HUP `cat $nginx_pid`

#可以执行以下脚本
[root@taoyuan ~]# sh -x /usr/local/sbin/nginx_log_rotate.sh
++ date -d '-1 day' +%Y%m%d
+ d=20180103
+ logdir=/tmp/
+ nginx_pid=/usr/local/nginx/logs/nginx.pid
+ cd /tmp/
++ ls test.com.log
+ for log in '`ls *.log`'
+ mv test.com.log test.com.log-20180103
++ cat /usr/local/nginx/logs/nginx.pid
+ /bin/kill -HUP 1055
  • 加任务计划
[root@taoyuan ~]# crontab -e
#加入如下内容
0 0 * * * /bin/bash /usr/local/sbin/nginx_log_rotate.sh

12.12 静态文件不记录日志和过期时间

  • 配置如下
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
   {
       expires     7d;
       access_log off;
   }
   location ~ .*\.(js|css)$
   {
       expires     12h;
       access_log off;
   }
  • -t && -s reload
[root@taoyuan ~]# /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@taoyuan ~]# /usr/local/nginx/sbin/nginx -s reload
  • 测试
[root@taoyuan ~]# cd /data/wwwroot/test.com/

[root@taoyuan test.com]# vim 1.gif
[root@taoyuan test.com]# vim 2.js
[root@taoyuan test.com]# curl -x127.0.0.1:80 test.com/1.gif
1.gif
[root@taoyuan test.com]# curl -x127.0.0.1:80 test.com/2.js
2.js
[root@taoyuan test.com]# curl -x127.0.0.1:80 test.com/index.html
test.com
[root@taoyuan test.com]# cat /tmp/test.com.log
127.0.0.1 - [04/Jan/2018:22:04:11 +0800] test.com "/index.html" 200 "-" "curl/7.29.0"
[root@taoyuan test.com]# curl -x127.0.0.1:80 test.com/index.html
test.com
[root@taoyuan test.com]# cat /tmp/test.com.log
127.0.0.1 - [04/Jan/2018:22:04:11 +0800] test.com "/index.html" 200 "-" "curl/7.29.0"
127.0.0.1 - [04/Jan/2018:22:04:33 +0800] test.com "/index.html" 200 "-" "curl/7.29.0"
