复制代码代码示例:

# cat  /proc/cpuinfo //查看cpu个数与频率
# dmidecode  |grep  "Product Name"  //查看服务器品牌和型号

复制代码代码示例:

# dmidecode|grep -P 'Maximum\s+Capacity'    //最大支持几G内存

# dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range       //总共几个插槽，已使用几个插槽
Size: 1024 MB       //此插槽有1根1G内存
Size: 1024 MB       //此插槽有1根1G内存
Size: 1024 MB       //此插槽有1根1G内存
Size: 1024 MB       //此插槽有1根1G内存
Size: No Module Installed       //此插槽未使用
