我的临时解决方案是重启mysql服务器服务......现在可以使用......

任何人都可以告诉我可能触发这个或者我怎么可能解决这个问题？

P.S我也试过增加my.cnf - ＆gt;从max_allowed_pa​​cket = 16M到max_allowed_pa​​cket = 128M ......我认为它修好了，但它回来了

1 个答案:

答案 0 :(得分：0)

打开wp-includes。搜索wp-db.php文件。如果找到该文件，请使用文本编辑器将其打开。使用文本编辑器的搜索工具，搜索：

$this->ready = true;

找到该行之后，在找到的行之后添加以下行：

//WP Query Gone Away Error Fix

$this->query("set session wait_timeout=600");

保存文件。现在，当您检查站点的错误日志时，您将不再看到该错误，这意味着该站点将不会像以前那样掉线。

这只是一个临时解决方法。您无法100％确定该错误不会再出现。通过执行此“修复”，MySQL将等待一段时间来完成查询。以下是一些永久修复此错误的提示：

尝试禁用/删除需要很高内存的插件 逐一禁用插件，然后找到导致此错误的插件 使用您只需要的插件。更多的插件意味着更多的C.P.U内存和MySQL服务器将过载
