由 dawei 我的服务器每周大约崩溃一次,并没有留下任何关于导致它的原因的线索.我检查了/ var / log / messages,它只是在某个时刻停止录制,并在执行硬重启时从计算机发布信息开始.
有什么我可以检查或我可以安装的软件可以确定原因吗？
我正在运行CentOS 7.
这是我的/ var / log / dmesg：https://paste.netcoding.net/cosisiloji.log中唯一的错误/问题

解决方法
您可以检查/ var / log / dmesg中的dmesg文件,该文件记录内核消息.消息日志只是记录服务和应用程序消息,如果您遇到内核错误,服务和应用程序将停止运行,但内核错误仍记录在dmesg中.
