优化wordpress的woocommerce网站运行速度

先设置permlink再安装两个plugin
(采用2个免费插件（WP Super Cache和Autooptimize）为WordPress网站提速)

前期准备工作

开启php preload

修改/etc/php.ini
或者修改 /etc/php.d/10-opcache.ini
增加一句opcache.preload=preload.php

修改前

; Specifies a PHP script that is going to be compiled and executed at server
; start-up.
; http://php.net/opcache.preload
;opcache.preload=

修改后变成

; Specifies a PHP script that is going to be compiled and executed at server
; start-up.
; http://php.net/opcache.preload
;opcache.preload=
opcache.preload=preload.php

设置网站的permlink固定链接

增加指令设置WooCommerce固定链接

Settings/Permalinks/Permalink structure/选择Post name
例如http://123.45.16.666/sample-post/

另外选择Product permalinks/选择Shop base with category
例如http://123.45.16.666/shop/product-category/sample-product/

修改default.conf

（这一步是为了防止permlink设置后，主网页显示正常，但子网页丢失路径无法显示报错）
nano /etc/nginx/conf.d/default.conf

改动一下文件，增加这句
try_files $uri $uri/ /index.php?$args;

改动后应该类似于

  location / {
        #root   /usr/share/nginx/html;
        root   /usr/share/nginx/html/wordpress;
        index  index.html index.htm index.php;
        try_files $uri $uri/ /index.php?$args;

    }
	rewrite /wp-admin$ $scheme://$host$uri/ permanent;

准备工作差不多了 重启一下
systemctl restart nginx

另外如果感兴趣

• 还可以增大wp-config.php文件的wp memory设置
  `define(‘WP_MEMORY_LIMIT’, ‘128M’);``

文件的的位置在这：
cd /usr/share/nginx/html/wordpress
nano wp-config.php

• 还可以修改php.ini
  nano /etc/php.ini
  调整下面这些设置

memory_limit = 128M这个要尽量大
upload_max_filesize = 12M这个要尽量小
post_max_size = 13M这个要是个中间大小
file_uploads = On
max_execution_time = 180这个是控制时间的，如果时间到了还跑不完，就会报错

修改隐藏的.htaccess文件

修改隐藏的.htaccess文件（注意将原来的备份成 .htaccess_old存档）
cd /usr/share/nginx/html/wordpress

ls -al进行查找否则可能看不到这个文件
将.htaccess文件内容改成下面，

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

安装优化plugin
