pcntl_fork 和 MySQL 连接消失了

问题描述

我有一个 foreach 循环，它在其中分叉.在进程 fork 之后，它访问数据库.我收到一个错误:

I have a foreach loop that forks within it. After the process forks, it accesses the database. I get an error:

SQLSTATE[HY000]: General error: 2006 MySQL server has gone away

问题是，我正在分叉之后连接到数据库.

The thing is, I'm connecting to the database after I've forked.

我的问题:为什么会发生这种情况?

My question: Why would this be happening?

如果发生这种情况，我是否真的在分叉之前访问了数据库??孩子会继承数据库连接吗?

If this happens, am I actually accessing the database before forking? Will the child inherit DB connections?

(注意:我可以发布代码，但它相当大，因为它都在类中，这可能是导致我在访问数据库时感到困惑的原因.您应该知道的另一件事是我正在使用 ZF.)

(note: I can post code, but it's rather large as it's all in classes, which could be what is causing my confusion of when I'm accessing the DB. Another thing you should know is I'm using ZF.)

阅读更多内容我看到分叉的孩子确实继承了他们父母的数据库连接，这是一个已知问题:http://php.net/manual/en/function.pcntl-fork.php#70721

Reading more into it I see forked children do inherit their parent's db connection, and it is a known problem: http://php.net/manual/en/function.pcntl-fork.php#70721
