Gzip压缩和利用浏览器缓存不适用于我的商店

Question

我正在尝试优化我的商店,我在我的.htaccess文件中添加了Gzip代码和杠杆浏览器缓存代码:

# Leverage browser caching using mod_expires #
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/pdf "access plus 1 month"
    ExpiresByType text/x-javascript "access plus 1 month"
    ExpiresByType application/x-shockwave-flash "access plus 1 month"
    ExpiresByType image/x-icon "access plus 1 year"
    ExpiresDefault "access plus 2 days"
</IfModule>
# End of Leverage browser caching using mod_expires #

# Leverage browser caching using mod_headers #
<IfModule mod_headers.c>
    <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
        Header set Expires "Wed, 15 Apr 2020 20:00:00 GMT"
        Header set Cache-Control "public"
    </FilesMatch>
</IfModule>
# End of Leverage browser caching using mod_headers #

Answer 1

启用Apache mod_headers和mod_expires模块

请通过以下代码检查mod_expires和mod_headers是否在您的商店中启用.

<?php phpinfo();?>

如果两个扩展程序都无法访问您的服务器,请按照以下步骤操作: -

步骤1 :-

现在使用SSH控制台登录服务器并继续以下步骤:

要启用mod_headers:

sudo a2enmod headers

要启用mod_expires:

sudo a2enmod expires

第2步 :-

完成服务器更新后,您需要重新启动Apache服务器才能使这些更改生效.在SSH控制台中输入以下行以重新启动Apache.

service apache2 restart

或者通过SSH中的代码重启服务器:

reboot

在.htaccess文件中使用以下代码.

<IfModule mod_headers.c>
     # YEAR
     <FilesMatch "\.(ico|gif|jpg|jpeg|png|flv|pdf)$">
          Header set Cache-Control "max-age=29030400"
     </FilesMatch>
     # WEEK
     <FilesMatch "\.(js|css|swf|woff)$">
         Header set Cache-Control "max-age=604800"
     </FilesMatch>
     # 45 MIN
     <FilesMatch "\.(html|htm|txt)$">
        Header set Cache-Control "max-age=86400"
     </FilesMatch>

     Header set Connection keep-alive

</IfModule>

<ifModule mod_gzip.c>
    mod_gzip_on Yes
    mod_gzip_dechunk Yes
    mod_gzip_item_include file \.(html?|txt|css|js|php|pl|asp|html)$
    mod_gzip_item_include handler ^cgi-script$
    mod_gzip_item_include mime ^text/.*
    mod_gzip_item_include mime ^application/x-javascript.*
    mod_gzip_item_exclude mime ^image/.*
    mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>

<ifmodule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</ifmodule>

清除商店缓存并重新加载网站网址后,请重新检查gtmetrix工具或使用工具的任何内容.
