centos 7 64 位 + apache 2.4 + php 5.6 访问网站时，页面报错：The connection was reset，打不开页面。 查看服务器日志： AH00052: child pid 8277 exit signal Segmentation fault (11)
请教下朋友们，这个问题如何处理？网上搜搜了半天，没找到解决方法。谢谢

没有 debug info，重新编译一份 httpd 和 libphp，编译的时候要打开调试选项，用带调试信息的程序生成 core 文件

MrMike OP @sagaxu 你的意思是重装 httpd 和 php ？我是直接用 yum install 安装的，手动编译的话，不熟悉，能否给一个完整的编译教程呢？谢谢。。

@MrMike yum 安装的 httpd 可以用 debuginfo-install httpd-2.4.6-67.el7.centos.5.x86_64 安装调试信息
