Apache網頁優化
Apache網頁優化
- 前言：在企業中，部署Apache後只採用默認的配置參數，引發網站很多問題，換言之默認配置是針對以前較低的服務器配置的，隨着互聯網時代的發展，之前的默認配置已經不適用於現在了。
網頁壓縮
1,檢查是否安裝mod_deflate模塊
apachectl -t -D DUMP_MODULES | grep "deflate"
2,如果沒有安裝mod_deflate模塊，重新編譯安裝Apache添加mod_deflate模塊
systemctl stop httpd.service
cd /usr/local/httpd/conf/
mv httpd.conf httpd.conf.bak
yum -y install gcc gcc-c++ pcre pcre-devel zlib-devel
cd /opt/httpd-2.4.29/
./configure \
--prefix=/usr/local/httpd \
--enable-so \
--enable-rewrite \
--enable-charset-lite \
--enable-cgi \
--enable-deflate #加入mod_deflate模塊
make -j 4 && make install
3,配置 mod_deflate 模塊啓用
vim /usr/local/httpd/conf/httpd.conf
--52行--修改
Listen 192.168.199.10:80
--105行--取消註釋
LoadModule deflate_module modules/mod_deflate.so #開啓mod_deflate模塊
--199行--取消註釋，修改
ServerName www.muzi.com:80
--末行添加--
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/css text/xml text/javascript text/jpg text/png
#代表對哪些內容啓用gzip壓縮
DeflateCompressionLevel 9 #代表壓縮級別，範圍爲1~9
SetOutputFilter DEFLATE #代表啓用deflate模塊對本站點的輸出進行gzip壓縮
</IfModule>
4,檢查安裝情況，啓動服務
apachectl -t #驗證配置文件的配置是否正確 httpd -t 是一樣的效果
apachectl -t -D DUMP_MODULES | grep "deflate" #檢查mod_deflate模塊是否以安裝
deflate_module (shared) #已安裝的正確結果
systemctl start httpd.service
5,測試 mod_deflate 壓縮是否生效
cd /usr/local/httpd/htdocs
先將music.jpg文件傳到/usr/local/httpd/htdocs目錄下
vim index.html
<html><body><hl>I opened my eyes last night and saw you in the low light.
Walking down by the bay, on the shore,staring up at the planes that aren't there anymore
I was feeling the night grow old and you were looking so cold
Like an introvert, I drew my over shirt.Around my arms and began to shiver violently before
You happened to look and see the tunnels all around me.Running into the dark underground</hl>
<img src="music.jpg"/>
</body></html>
