php - 新鲜的 MediaWiki 永久加载

Question

我正在尝试在共享主机上安装 MediaWiki。我下载了 MediaWiki 1.22.0 并运行安装，没有任何问题。但是当我尝试访问主页时，它会永远加载。我激活了 Debug模式，清空了 debug.log，然后加载主页，直到浏览器足够了。我搜索了“错误”一词并复制了以下上下文:

显然连接太多，但为什么呢？也许是因为它是共享主机？

Answer 1

该错误意味着数据库目前无法处理更多连接。发生这种情况的原因有很多。一些常见的例子可能是......

• 您的特定网站目前受到大量流量(例如搜索引擎抓取工具或大量浏览者)的攻击，导致同时发生的页面请求数量超出了数据库的处理能力。
• 您的共享主机的配置方式可能(而且很不幸)是多个帐户共享数据库资源，而不同的网站消耗了所有这些资源。

有多种方法可以solve or mitigate this problem涉及更改 MySQL 数据库设置(例如增加并发连接数...假设服务器可以支持)。

如果您没有数据库服务器的管理访问权限，那么您的选择将受到限制。检查您的托管提供商的数据库文档，看看您是否有任何选择。
