Linux下使用dmidecode查看服务器的详细的硬件配置
dmidecode可以查看服务器硬件的详细配置,下面是DMI的类型：
语法格式：
DB01:~ # dmidecode --help Usage: dmidecode [OPTIONS] Options are: -d, --dev-mem FILE Read memory from device FILE (default: /dev/mem) -h, --help Display this help text and exit -q, --quiet Less verbose output -s, --string KEYWORD Only display the value of the given DMI string -t, --type TYPE Only display the entries of given type -u, --dump Do not decode the entries -V, --version Display the version and exit

其它硬件信息，也可以类似查看。这个命令结合dmesg去查看，收集的信息会比较全
