Wordpress Redis缓存加速

前端缓存的PHP脚本

$wget https://gist.githubusercontent.com/JimWestergren/3053250/raw/d9e279e31cbee4a1520f59108a4418ae396b2dde/index-with-redis.php
$chown www.www ./index-with-redis.php

修改index-with-redis.php

$cf = 0;                        // set to 1 if you are using cloudflare
$debug = 1;                     // set to 1 if you wish to see execution time and cache actions
$display_powered_by_redis = 0;  // set to 1 if you want to display a powered by redis message with execution time, see below

替换index.php

mv index.php index.php_bk #替换到原来的index.php，也可以改nginx伪静态规则
mv index-with-redis.php index.php

缓存问题
index-with-redis.php中有注释

Appending a ?c=y to a url deletes the entire cache of the domain, only works when you are logged in
Appending a ?r=y to a url deletes the cache of that url
Submitting a comment deletes the cache of that page
Refreshing (f5) a page deletes the cache of that page

• 登录后台网站url后面加上?c=y即可刷新整个网站
• 可以在网站页面后面加上?r=y即可手工刷新
• 提交评论会自动刷新页面
• 刷新(f5)页面也可以刷新页面
