利用WordPress Cachify插件实现缓存加速提高网站打开速度

今天老蒋在研究WordPress加速的时候看到有网友推荐这款Cachify插件。从介绍功能上可以看到Cachify是通过缓存文章、页面和自定义文章类型为静态内容来优化我们网站的页面加载速度。我们可以从以下几个缓存方式中选择:数据库、服务器硬盘(HDD)、Memcached(仅在Nginx上可用)或 APC(Alternative PHP Cache)——直接在Web服务器的系统缓存中。用户访问时,页面或文章可直接从缓存中拉取。数据库和查询和PHP请求数可显著减少,如果选择了合适的缓存方式,这个数字可能为0。

如果我们仅仅只用这个插件的话,可以选择硬盘加速模式。

如果我们选择的是硬盘换成,需要在上面 修改我们的.htaccess或者是Nginx配置配置文件。
我们还可以配合Memcached进行加速,比如我们在上图中选择Memcached加速模式,但是前提是我们的当前服务器是有安装Memcached。

比如我们在用宝塔面板的话,需要启动安装Memcached软件。
然后在站点配置中还需要配置设置。

#Extension of the Nginx configuration file ( https://gist.github.com/sergejmueller/6113816#file-gistfile1-txt)
#If you have errors please try to change memcached_pass localhost:11211; to memcached_pass 127.0.0.1:11211; This forces IPv4 because some servers that allow ipv4 and ipv6 are configured to bind memcached to ipv4 only.
## GZIP
gzip_static on;
## CHARSET
charset utf-8;
## INDEX LOCATION
location / {
    error_page 404 405 = @nocache;
 
    if ( $query_string ) {
        return 405;
    }
    if ( $request_method = POST ) {
        return 405;
    }
    if ( $request_uri ~ "/wp-" ) {
        return 405;
    }
    if ( $http_cookie ~ (wp-postpass|wordpress_logged_in|comment_author)_ ) {
        return 405;
    }
    default_type text/html;
    add_header X-Powered-By Cachify;
    set $memcached_key $host$uri;
    memcached_pass localhost:11211;
}
location @nocache {
    try_files $uri $uri/ /index.php?$args;
}

这是官方给的示范Nginx设置。
这里,老蒋知道这个Cachify插件是可以实现WordPress缓存加速的,后面实战详细的来操作介绍使用Cachify插件的加速功能。
