centos7 异常关机了，怎么查看系统的异常日志? crash中也没有dump的文件. 这是messages日志: Feb 26 11:14:03 moon systemd-logind: Removed session 11. Feb 26 11:14:56 moon systemd: Created slice user-0.slice.

CentOS的应该和Redhat的是一样的 /var/log/message中有些日志可以看 如果是kernel crash了 在/var/crash/下 有kernel crash的时候的日志环境 当然 前提是你安装时默认运行kernel crash后有dump文件 (责任编辑：IT) |
