全新MediaWiki永久加載

Question

我正在嘗試在共享主機上安裝MediaWiki。我下載了MediaWiki 1.22.0並運行安裝而沒有任何問題。但是當我嘗試訪問主頁時，它永遠永遠加載。我激活了調試模式，清空了debug.log，然後加載了主頁面，直到瀏覽器有足夠的空間。我搜索單詞「錯誤」，並複製以下方面：

顯然太多的連接，但是爲什麼呢？也許是因爲它是共享主機？

Answer 1

該錯誤表示數據庫此時無法處理更多連接。這可能會發生很多原因。一些常見的例子可能是......

• 您的特定網站沒有獲得通過大量的流量，此刻擊（如搜索引擎爬蟲或只是很多觀衆），導致比數據庫更多的併發頁面請求可以處理。
• 您的共享主機配置方式可能會（可惜）多個帳戶共享數據庫資源，而不同的網站已經佔用了所有這些資源。

solve or mitigate this problem有多種方法需要更改MySQL數據庫設置（例如增加同時連接的數量......假設服務器可以支持它）。

如果您沒有對數據庫服務器的管理訪問權限，那麼您將擁有有限的選項。檢查您的託管服務提供商的數據庫文檔，看看您是否有任何選擇。
