Apache启动失败- Centos7

Question

我运行了一个yum更新，之后服务器在我的CentOS7VM上无法启动。

apache Apache/2.4.6 (CentOS) OpenSSL/1.0.1e-fips PHP/5.4.16

内核版本- 3.10.0-327.10.1.el7.x86_64

以下是systemctl展示的内容。我不知道更新后是什么坏了。

我可以请求帮助，以获得一些指针，以进一步挖掘，或谁谁看过这个&知道如何修复，请？

Answer 1

请您在重新启动yoru服务器上的httpd服务时，请为您的服务器设置正确的主机名，并选中“-xn Can -xn”命令，您将通过日志Can-xn命令得到httpd问题的确切根源。

当我安装/卸载free-ipa时，我遇到了这种情况，因为在/etc/ httpd / can中创建了nss.conf，所以您可以尝试将这个文件像我一样移动到另一个目录，现在httpd服务就像一个魅力一样工作。
