10-2 11 靜態不記錄 日誌切割 靜態過時時間

11.22 訪問日誌不記錄靜態文件

• 網站大多元素爲靜態文件，如圖片、css、js等，這些元素能夠不用記錄

把虛擬主機配置文件改爲以下：

conf/extra/http-v
...
<VirtualHost *:80>
	DocumentRoot "/data/wwwroot/ddd.com"
	ServerName ddd.com
	ServerAlias ttt.com eee.com www.example.com
	SetEnvIf Request_URI ".*\.gif$" img
	SetEnvIf Request_URI ".*\.jpg$" img
	SetEnvIf Request_URI ".*\.png$" img
	SetEnvIf Request_URI ".*\.bmp$" img
	SetEnvIf Request_URI ".*\.swf$" img
	SetEnvIf Request_URI ".*\.js$" img
	SetEnvIf Request_URI ".*\.css$" img 
 CustomLog "logs/ddd.com-access_log" combined env=!img
</VirtualHost>
...
 bin/apachectl -t/graceful
 cd /data/wwwroot/ddd.com/  //在這目錄下上傳一個圖片

能夠看到，沒有訪問png的記錄

11.23 訪問日誌切割

CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/ddd.com-access_%Y%m%d.log 86400" combined env=!img

11.24 靜態元素過時時間

• 瀏覽器訪問網站的圖片時會把靜態的文件緩存在本地電腦裏，這樣下次再訪問時就不用去遠程下載了

apache能夠設置緩存保存時間

cd /usr/local/apache2.4/ 
vim conf/extra/httpd-vhosts.conf
...
<IfModule mod_expires.c>
ExpiresActive on 
ExpiresByType image/gif  "access plus 1 days"
ExpiresByType image/jpeg "access plus 24 hours"
ExpiresByType image/png "access plus 24 hours"
ExpiresByType text/css "now plus 2 hour"
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>
...
vim conf/httpd.conf 
	/expires_module //開啓
bin/apachectl -M | grep expire 
bin/apachectl -t 
bin/apachectl graceful 
curl -x127.0.0.1:80 ddd.com/aming.png -I

如圖，cache-control: max-age爲緩存有效期
