本文介绍如何使用sudo apt-get install mcelog命令安装mcelog，并详细解释了mcelog的各个选项功能，包括如何设置CPU类型、频率、后台运行等。此外还提供了调试与配置文件的使用方法。

$ sudo apt-get install mcelog

Decode machine check ASCII output from kernel logs
Options:
--cpu CPU           Set CPU type CPU to decode (see below for valid types)
--cpumhz MHZ        Set CPU Mhz to decode time (output unreliable, not needed on new kernels)
--raw		     (with --ascii) Dump in raw ASCII format for machine processing
--daemon            Run in background waiting for events (needs newer kernel)
--ignorenodev       Exit silently when the device cannot be opened
--file filename     With --ascii read machine check log from filename instead of stdin
--syslog            Log decoded machine checks in syslog (default stdout or syslog for daemon)
--syslog-error	     Log decoded machine checks in syslog with error level
--no-syslog         Never log anything to syslog
--logfile filename  Append log output to logfile instead of stdout
--dmi               Use SMBIOS information to decode DIMMs (needs root)
--no-dmi            Don't use SMBIOS information
--dmi-verbose       Dump SMBIOS information (for debugging)
--filter            Inhibit known bogus events (default on)
--no-filter         Don't inhibit known broken events
--config-file filename Read config information from config file instead of /etc/mcelog/mcelog.conf
--foreground        Keep in foreground (for debugging)
--num-errors N      Only process N errors (for testing)
