减少 CloudSQL 实例小时数 (wordpress)

Question

我在 GAE 上安装了 wordpress。这是一个更新很少的网站，每天的访问者很少（最多 100 人）。我想缓存这个网站以最小化 cloudSQL 成本。

我应该采取哪些步骤来最大程度地减少 CloudSQL 实例的启动？

我已经安装了 MEMCACHED 插件和我的 BATCACHED 插件。

我的 wp-config 有以下内容：

$batcache = [
      'seconds'=>0,
      'max_age'=>300*60, // 300 minutes
      'debug'=>false
    ];

我的 app.yaml：

application: MY ID
version: 104
runtime: php
api_version: 1
default_expiration: "1d"

我想知道在启动我的 CloudSQL 实例时减少 wordpress 的所有方法。另外，我想知道如何检查缓存是否正常工作。

目前，即使我在没有登录 wordpress 的情况下访问一个页面，它也会显示一个 CloudSQL 实例已启动（一个活动连接），我认为如果缓存工作正常，情况就不应该出现这种情况

Answer 1

我相当肯定，即使使用 batcache，WordPress 核心仍然会尝试连接到 SQL 数据库以确保连接有效。

您需要研究其中一个静态整页缓存插件以尝试实现您所追求的目标 - 它们似乎有选项可以在不加载 WordPress 核心的情况下返回页面。

Answer 2

如果您已设置 Scheduled Tasks 以频繁访问 wp-cron.php，您可能需要考虑降低此运行的频率。
