wordpress速度优化为服务器减压的技巧总结

wordpress 的功能很强大，插件支持也很广泛，但是仍然有很多性能优化余地，比如较高的服务器占用，和访问速度。用wordpress做CMS站点时，可以从以下方面去执行wordpress速度优化，为服务器减压！

时间就是生命，等待就是煎熬，速度就是用户体验！

1.Cookie的静态化制作

约有80％至90％的时间，访客要花费大量的时间等待WordPress加载静态内容。如：图像，CSS，JS脚本，flash等。所以你可以优化内容，更快捷地让WordPress加载一个cookie域。消除负载时珍贵的时间，当然这可能看起来并不多。

wordpress只要修改一下wp-config.php就好了！

在合适的位置加入

define(“WP_CONTENT_URL”, “http://static.***.com”);

define(“COOKIE_DOMAIN”, “www.***.com”);

然后用用“bloginfo(template_directory’)”这段代码加入你要实现的静态内容中即可！

2.设置静态内容缓存

用相关的缓存插件也需要这个步骤，修改.htaccess文件

代码如下：

<IfModule mod_expires.c>
ExpiresActive on
# Perhaps better to whitelist expires rules? Perhaps.
ExpiresDefault “access plus 1 month”
# cache.appcache needs re-requests
# in FF 3.6 (thx Remy ~Introducing HTML5)
ExpiresByType text/cache-manifest “access plus 0 seconds”
# Your document html
ExpiresByType text/html “access plus 0 seconds”
# Data
ExpiresByType text/xml “access plus 0 seconds”
ExpiresByType application/xml “access plus 0 seconds”
ExpiresByType application/json “access plus 0 seconds”
# RSS feed
ExpiresByType application/rss+xml “access plus 1 hour”
# Favicon (cannot be renamed)
ExpiresByType image/x-icon “access plus 1 week”
# Media: images, video, audio
ExpiresByType image/gif “access plus 1 month”
ExpiresByType image/png “access plus 1 month”
ExpiresByType image/jpg “access plus 1 month”
ExpiresByType image/jpeg “access plus 1 month”
ExpiresByType video/ogg “access plus 1 month”
ExpiresByType audio/ogg “access plus 1 month”
ExpiresByType video/mp4 “access plus 1 month”
ExpiresByType video/webm “access plus 1 month”
# HTC files (css3pie)
ExpiresByType text/x-component “access plus 1 month”
# Webfonts
ExpiresByType font/truetype “access plus 1 month”
ExpiresByType font/opentype “access plus 1 month”
ExpiresByType application/x-font-woff “access plus 1 month”
ExpiresByType image/svg+xml “access plus 1 month”
ExpiresByType application/vnd.ms-fontobject “access plus 1 month”
# CSS and JavaScript
ExpiresByType text/css “access plus 1 year”
ExpiresByType application/javascript “access plus 1 year”
ExpiresByType text/javascript “access plus 1 year”
<IfModule mod_headers.c>
Header append Cache-Control “public”
</IfModule>
</IfModule>

3.优化数据库

WordPress的免费插件即可解决，Yoast Optimize DB和WP DB Manager。

4.尽量缓存媒体文件

创建缓存可以很简单地通过插件完成。推荐缓存工具：WP Super Cache， Hyper Cache，和W3 Total Cache。用这些生成HTML文件，可以节省很多时间。

5.CDN加速

cdn一般是收费，不过也有免费的CDN。

推荐一些免费CDN：Webluker，cloudflare

6.压缩JS和CSS文件

JS压缩工具推荐：Closure Compiler ，Minify JavaScript. CSS压缩工具推荐：Minify CSS ，CSS Compressor

7.压缩图像

图像的加载可以算是最耗时的，用BMP或者PSD作为图像速度会更慢，建议尽量使用JPG压缩。优化图片的好处是显而易见的，首先可以节省大量的带宽资源；其次，图片优化，可以大大提供博客整体的载入速度。

8.GZIP压缩

GZIP的压缩在一定限度内是很不错的！而且通过gzip压缩还可以屏蔽广告，GZIP的压缩代码如下：修改.htaccess文件

<IfModule mod_deflate.c>
# force deflate for mangled headers
# developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping/
<IfModule mod_setenvif.c>
<IfModule mod_headers.c>
SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)s*,?s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding
RequestHeader append Accept-Encoding “gzip,deflate” env=HAVE_Accept-Encoding
</IfModule>
</IfModule>
# HTML, TXT, CSS, JavaScript, JSON, XML, HTC:
<IfModule filter_module>
