Php 永远新鲜的MediaWiki加载

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

显然连接太多了，但为什么？可能是因为它是共享主机？

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

• 目前，您的特定站点受到大量流量的影响（例如，搜索引擎爬虫或大量的浏览者），导致数据库无法处理更多的同步页面请求
• 您的共享主机的配置方式可能是多个帐户共享数据库资源，而另一个站点消耗了所有这些资源，这是可能的（也是不幸的）

有多种方法可以改变MySQL数据库设置（例如，增加同时连接的数量…假设服务器可以支持）

如果您没有对数据库服务器的管理访问权限，那么您将拥有有限的（如果有的话）选项。查看托管提供商的数据库文档，看看您是否有任何选择
