Apache配置不记录访问静态文件的日志
-
网站大多元素为静态文件，如图片、css、js等，这些元素可以不用记录
-
vhost原始配置
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "/usr/local/apache2.4/test-webroot"
ServerName test.com
ServerAlias www.test.com
ErrorLog "logs/test.com-error_log"
CustomLog "logs/test.com-access_log" combined
</VirtualHost>
- 访问www.test.com/1.jpg
[root@test-a extra]# curl -x127.0.0.1:80 -l www.test.com/1.png
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /1.png was not found on this server.</p>
</body></html>
[root@test-a extra]# tail -n 1 /usr/local/apache2.4/logs/test.com-access_log
127.0.0.1 - - [19/Nov/2018:07:00:54 +0800] "GET HTTP://www.test.com/1.png HTTP/1.1" 404 203 "-" "curl/7.29.0"
- 进行限制配置
[root@test-a extra]# vim httpd-vhosts.conf # 进行如下配置
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "/usr/local/apache2.4/test-webroot"
ServerName test.com
ServerAlias www.test.com
SetEnvIf Request_URI ".*\.gif$" static_file
SetEnvIf Request_URI ".*\.jpg$" static_file
SetEnvIf Request_URI ".*\.png$" static_file
SetEnvIf Request_URI ".*\.bmp$" static_file
SetEnvIf Request_URI ".*\.swf$" static_file
ErrorLog "logs/test.com-error_log"
CustomLog "logs/test.com-access_log" combined env=!static_file
</VirtualHost>
- 重新加载配置，访问测试
[root@test-a extra]# /usr/local/apache2.4/bin/apachectl graceful
[root@test-a extra]# tail -n 1 /usr/local/apache2.4/logs/test.com-access_log

[root@test-a extra]# curl -x127.0.0.1:80 -l www.test.com/123.png
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

访问日志切割
-
日志一直记录总有一天会把整个磁盘占满，所以有必要让它自动切割，并删除老的日志文件。
-
配置，使用Apache自带的切割工具rotatelogs进行日志文件切割
[root@test-a extra]# ls /usr/local/apache2.4/logs/
access_log dummy-host.example.com-access_log httpd.pid
dummy-host2.example.com-access_log dummy-host.example.com-error_log test.com-access_log
dummy-host2.example.com-error_log error_log test.com-error_log
[root@test-a extra]# vim httpd-vhosts.conf # 进行如下的配置
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "/usr/local/apache2.4/test-webroot"
ServerName test.com
ServerAlias www.test.com
SetEnvIf Request_URI ".*\.gif$" static_file
SetEnvIf Request_URI ".*\.jpg$" static_file
SetEnvIf Request_URI ".*\.png$" static_file
SetEnvIf Request_URI ".*\.bmp$" static_file
SetEnvIf Request_URI ".*\.swf$" static_file
ErrorLog "logs/test.com-error_log"
CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/test.com-access_log-%Y-%m-%d 86400" combined env=!static_file
</VirtualHost>
[root@test-a extra]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@test-a extra]# curl -x127.0.0.1:80 -l www.test.com/index.php
hello, test-webroot from www.test.com[root@test-a extra]#
[root@test-a extra]#
[root@test-a extra]# ls /usr/local/apache2.4/logs/
access_log dummy-host.example.com-access_log httpd.pid test.com-error_log
dummy-host2.example.com-access_log dummy-host.example.com-error_log test.com-access_log
dummy-host2.example.com-error_log error_log test.com-access_log-2018-11-18
配置静态文件过期时间
-
浏览器访问网站的图片时会把静态的文件缓存在本地电脑里，这样下次再访问时就不用去远程下载了
-
需要使用到expires_module
-
配置测试
[root@test-a extra]# vim httpd-vhosts.conf # 添加如下配置
<IfModule mod_expires.c>
ExpiresActive on
ExpiresByType image/gif "access plus 1 day"
ExpiresByType image/jpeg "access plus 24 hours"
ExpiresByType image/png "access plus 24 hours"
ExpiresByType text/css "now plus 2 hours"
ExpiresByType application/x-javascript "now plus 2 hours"
ExpiresByType application/javascript "now plus 2 hours"
ExpiresByType application/x-shockwave-flash "now plus 2 hours"
ExpiresDefault "now plus 0 min"
</IfModule>
[root@test-a test-webroot]#
[root@test-a test-webroot]# /usr/local/apache2.4/bin/apachectl -M | grep expires # 查看expires_module是否可用
[root@test-a test-webroot]# vim /usr/local/apache2.4/conf/httpd.conf # 取消该模块的注释
[root@test-a test-webroot]# /usr/local/apache2.4/bin/apachectl -M | grep expires
expires_module (shared)
[root@test-a test-webroot]# /usr/local/apache2.4/bin/apachectl graceful
[root@test-a test-webroot]#
[root@test-a test-webroot]# curl -x127.0.0.1:80 www.test.com/1.jpg -I
