验证：

redis-cli
keys *
keys PREFIX:cache*
get "PREFIX:page:http://www.xxx.org.cn/node/567:html" tags
get "PREFIX:page:http://www.xxx.org.cn/node/567:html" data
del [cache-id]

drupal 8的网站，开启了page cache模块。

cache id: PREFIX:cache:page:http://example.com/[url]

通过执行redis-cli可以登录redis，执行

del [cache id]即可
