centos Apache “子进程 pid *** 退出信号：段错误 (11)” 在错误日志中

Question

我在我的Apache日志文件中看到很多“Child pid XXXX exit signal Segmentation fault (11)”的错误信息。

我尝试了这里提供的解决方案，但没有找到错误的原因。

请帮我理解这个错误，它似乎和Python 2.4有关。

补充一下，这个产生错误的网站完全是用PHP写的。

以下是gdb的结果：

检查一下你的 PHP-FPM 和 PHP 的版本是否一致。确保你的 PHP 和 PHP-FPM 的配置是正确的，并且它们的版本是匹配的。

PHP-FPM 的配置文件在 /etc/php/7.0/fpm，而 PHP 的版本可能在更新时出现了不同步的情况。更新后的 PHP（在 /etc/php/7.3/）可能会导致 Apache 的子进程崩溃，因为在 /etc/php/7.3/ 中缺少对应的 PHP-FPM 配置。

我的服务器团队通过重新编译Apache解决了这个问题。

他们使用了命令：SSH

/scripts/easyapache

然后就好了。

在此之前，我的网站是空白的。

希望这能帮到你。

今天我找到了我问题的解决办法，原来是因为一个Python模块。我把它删掉了，问题就解决了。

我不知道那是不是个旧版本什么的，但反正现在问题解决了。
