Wordpress 手动优化开启fast-cache和brotli

1、禁用文章修订版，在 wp-config.php文件中添加:

<pre class="wrap:true lang:default decode:true "> define('WP_POST_REVISIONS', false);

1	<pre class="wrap:true lang:default decode:true "> define('WP_POST_REVISIONS', false);

~~再用WP clean up插件清理下sql~~ 2018推荐用wp-sweep
2、禁用自动保存，修改下面连个，注释掉，测试版本4.7.1

<pre class="wrap:true lang:default decode:true ">wp-admin/post-new.php 直接注释掉
wp-admin/post.php 注释掉 在if ( 'attachment' !== $post_type );《---加个分号
如：//wp_enqueue_script('autosave');

<pre class="wrap:true lang:default decode:true ">wp-admin/post-new.php 直接注释掉

wp-admin/post.php 注释掉在if ( 'attachment' !== $post_type );《---加个分号

如：//wp_enqueue_script('autosave');

插件安装
2017年：（我的VPS配置的是nginx/1.10.2+PHP 7.1.0+memcached 1.4.34 开启fastcgi_cache）：
查Nginx是否安装ngx_cache_purge

2019年：我配置nginx1.17.1+mysql 8+php 7.3.7 用的是腾讯云1G1核1m 三年版 php装了opcache 其它全部没装。wp的插件上么加速也全没装，因需要装了个Jetpack，如果你非要装就装有Database Cache（数据库缓存） Object Cache （对象缓存）这类加速的就行了,内存小我没装memcached。

<pre class="wrap:true lang:default decode:true ">nginx -V 2>&1 | grep -o ngx_cache_purge

1	<pre class="wrap:true lang:default decode:true ">nginx -V 2>&1 \| grep -o ngx_cache_purge

为了方便我建议到：https://caohuan.com/1-service-in.html 下个安装包，也推荐用oneinstack

<pre class="wrap:true lang:default decode:true ">
cd /root/oneinstack/src
wget http://nginx.org/download/nginx-1.17.1.tar.gz(请根据自己需要的版本修改链接地址，下文中的目录也要作相应的修改)

nginx -V #查看nginx编译参数，最后加上--add-module=../ngx_cache_purge-2.3

cd /root/oneinstack/src

wget http://nginx.org/download/nginx-1.17.1.tar.gz(请根据自己需要的版本修改链接地址，下文中的目录也要作相应的修改)

cd /root/oneinstack/src/nginx-1.17.1

nginx -V 2>&1 | grep -o ngx_cache_purge
nginx -V 2>&1 | grep -o ngx_brotli
# 显示ngx_cache_purge 和 ngx_brotli表示已经安装成功
测试
nginx -t
无错使nginx配置生效

<pre class="wrap:true lang:default decode:true ">nginx -t reload 或 service nginx reload

1	<pre class="wrap:true lang:default decode:true ">nginx -t reload 或 service nginx reload

开启cache要在nginx.conf和你的虚拟机server添加，下面这段加在server前面

<pre class="wrap:true lang:default decode:true ">
#例：fastcgi_cache_path /tmp/nginx-cache levels=1:2 keys_zone=WORDPRESS:500m inactive-1d max_size=2g;

fastcgi_cache_use_stale error timeout invalid_header http_500;

fastcgi_ignore_headers Cache-Control Expires Set-Cookie;

fastcgi_cache_min_uses 1;#访问一次生成缓存

把brotil配置在gzip的后面吧

<pre class="wrap:true lang:default decode:true ">
brotli on; #启用
brotli_comp_level 8; #压缩等级，默认6，最高11，太高的压缩水平可能需要更多的CPU 
brotli_buffers 16 8k; #请求缓冲区的数量和大小
brotli_min_length 20; #指定压缩数据的最小长度，只有大于或等于最小长度才会对其压缩。这里指定20字节
brotli_types text/plain application/javascript application/x-javascript text/javascript text/css application/xml text/html application/json image/svg application/font-woff application/vnd.ms-fontobject application/vnd.apple.mpegurl image/x-icon image/jpeg image/gif image/png image/bmp; #指定允许进行压缩类型
brotli_static always; #是否允许查找预处理好的、以.br结尾的压缩文件，可选值为on、off、always 
brotli_window 512k; #窗口值，默认值为512k

brotli on; #启用

brotli_comp_level 8; #压缩等级，默认6，最高11，太高的压缩水平可能需要更多的CPU

brotli_buffers 16 8k; #请求缓冲区的数量和大小

brotli_min_length 20; #指定压缩数据的最小长度，只有大于或等于最小长度才会对其压缩。这里指定20字节

brotli_types text/plain application/javascript application/x-javascript text/javascript text/css application/xml text/html application/json image/svg application/font-woff application/vnd.ms-fontobject application/vnd.apple.mpegurl image/x-icon image/jpeg image/gif image/png image/bmp; #指定允许进行压缩类型

brotli_static always; #是否允许查找预处理好的、以.br结尾的压缩文件，可选值为on、off、always

brotli_window 512k; #窗口值，默认值为512k

然后在你的虚拟机部分，添加在伪静态之前吧：

<pre class="wrap:true lang:default decode:true ">     set $skip_cache 0;
        if ($request_method = POST) {
            set $skip_cache 1;
        }   
        if ($query_string != "") {
            set $skip_cache 1;
        }   
        if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
            set $skip_cache 1;
        }   
        if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
            set $skip_cache 1;
        }

<pre class="wrap:true lang:default decode:true "> set $skip_cache 0;

if ($request_method = POST) {

set $skip_cache 1;

}

if ($query_string != "") {

set $skip_cache 1;

}

if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {

set $skip_cache 1;

}

if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {

set $skip_cache 1;

}

然后我的php部分：

<pre class="wrap:true lang:default decode:true ">  
  location ~ [^/]\.php(/|$) {
    #fastcgi_pass remote_php_ip:9000;
    try_files $uri =404;
    fastcgi_pass unix:/dev/shm/php-cgi.sock;
    fastcgi_index index.php;
    include fastcgi.conf;
                add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
                fastcgi_cache_bypass $skip_cache;
                fastcgi_no_cache $skip_cache;
                add_header X-Cache "$upstream_cache_status From $host";
                fastcgi_cache WORDPRESS;
                add_header Nginx-Cache "$upstream_cache_status";
                add_header Last-Modified $date_gmt;

                add_header X-Content-Type-Options nosniff;
                add_header X-XSS-Protection "1; mode=block"; 
                fastcgi_cache_valid 200 301 302 1d;
                etag  on;
  }

location ~ [^/]\.php(/|$) {

#fastcgi_pass remote_php_ip:9000;

try_files $uri =404;

fastcgi_pass unix:/dev/shm/php-cgi.sock;

fastcgi_index index.php;

include fastcgi.conf;

add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

fastcgi_cache_bypass $skip_cache;

fastcgi_no_cache $skip_cache;

add_header X-Cache "$upstream_cache_status From $host";

fastcgi_cache WORDPRESS;

add_header Nginx-Cache "$upstream_cache_status";

add_header Last-Modified $date_gmt;

add_header X-Frame-Options SAMEORIGIN;

add_header X-Content-Type-Options nosniff;

add_header X-XSS-Protection "1; mode=block";

fastcgi_cache_valid 200 301 302 1d;

etag on;

}

~~重启系统后shm内存中nginx-cache文件夹会丢失，为了使重启生效（自动创建文件夹），修改/etc/init.d/nginx的make_dirs下一行（大概52行）添加：~~

<del><pre class="wrap:true lang:default decode:true ">[ ! -d '/dev/shm/nginx-cache' ] && { mkdir /dev/shm/nginx-cache; chown -R ${user}.$user /dev/shm/nginx-cache; }

1	<del><pre class="wrap:true lang:default decode:true ">[ ! -d '/dev/shm/nginx-cache' ] && { mkdir /dev/shm/nginx-cache; chown -R ${user}.$user /dev/shm/nginx-cache; }

3. WordPress安装~~Nginx Helper插件或~~ NGINX Cache Optimizer插件
修改wordpress网站根目录wp-config.php添加如下行(dev/shm是centos内存)：

<pre class="wrap:true lang:default decode:true ">define('RT_WP_NGINX_HELPER_CACHE_PATH','/dev/shm/nginx-cache');

1	<pre class="wrap:true lang:default decode:true ">define('RT_WP_NGINX_HELPER_CACHE_PATH','/dev/shm/nginx-cache');

可参考原文：https://blog.linuxeye.com/439.html
然后建立一个PHP时间文件,代码：

<pre class="wrap:true lang:default decode:true ">< ? php echo time(); ? >

1	<pre class="wrap:true lang:default decode:true ">< ? php echo time(); ? >

测试,缓存了显示的结果不变：

<pre class="wrap:true lang:default decode:true ">[root@default ~]# curl https://caohuan.com/time.php;echo

~~1、我在php7，我打开debug安装WP Super Cache是有错误的，换了wp fastest cache~~
2、开启nginx的fastcgi_cache，有memcached我这小站也够用的，VPS有不是wordpress所以有是连个一起分着用下。安装插件NGINX Cache Optimizer(这个插件会在wp-content加入object-cache.php但如果你的memcached不工作了这个文件要删除不然网站500)，或者可以装一个nginx helper，这个没前者的功能多，两个都可以管理fastcgi_cache缓存，但前者多了个memcached。

2019年：我不再安装加速插件，现在的cpu和php版本已经不需要了这些了。可能我站小，机器大的缘故吧。

vhost配置：
在附件，提供本站正在用的vhost.conf 和nginx.conf,和几篇实用的配置文章，地址不提供了，网站有时站长不做了，技术就流失了，保存下来长久点。

如果你的主机有多个独立的网站，你可以把nginx.conf的这部分添加到虚拟机内：

<pre class="wrap:true lang:default decode:true ">http {
    fastcgi_cache_path /var/run/nginx-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m;
    fastcgi_cache_key "$scheme$request_method$host$request_uri";
    fastcgi_cache_use_stale error timeout invalid_header http_500;
    fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
    add_header rt-Fastcgi-Cache $upstream_cache_status;

    ...
}

<pre class="wrap:true lang:default decode:true ">http {

fastcgi_cache_path /var/run/nginx-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m;

fastcgi_cache_key "$scheme$request_method$host$request_uri";

fastcgi_cache_use_stale error timeout invalid_header http_500;

fastcgi_ignore_headers Cache-Control Expires Set-Cookie;

add_header rt-Fastcgi-Cache $upstream_cache_status;

...

}

---2019.06.24
估计很多人也注意到了没开域名证书时，你装了br和gzip共存，在header的显示还是
Accept-Encoding: gzip
开域名证书后浏览器不同显示就不同
Accept-Encoding: gzip, deflate, br
或者
Accept-Encoding: br
