![Apache 无法启动 Centos 7,没有错误日志 -xe](https://linux22.com/image/683713/Apache%20%E6%97%A0%E6%B3%95%E5%90%AF%E5%8A%A8%20Centos%207%EF%BC%8C%E6%B2%A1%E6%9C%89%E9%94%99%E8%AF%AF%E6%97%A5%E5%BF%97%20-xe.png)
我无法说出它何时开始,因为我最近搬家了,刚刚完成实验室的设置。虽然在使用我的 NGINX/Apache 服务器启动虚拟机时,我进行了 yum 更新,Apache 也升级了,但现在它不再启动,也没有发出错误。我不能说它是在升级之前还是之后发生的,也不记得我运行的旧版本。我知道缺乏信息可能没有帮助……通常,当我遇到语法问题或缺少模块等时,它会通知我。我还检查了下面的 PID 的 audit.log,那里也没有任何东西,所以我也不相信 SELinux 会阻止它。
提前感谢任何建议。

答案1
我最终在 error_log 中找到了错误,虽然我最初在审计日志中没有看到任何内容,但似乎由于 SELinux 它没有权限访问虚拟主机的日志文件。
