linux查看内存硬件情况

1、查看内存槽数、那个槽位插了内存，大小是多少

dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range

[root@webserver ~]# dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range

        Size: 1024 MB

        Size: 1024 MB

        Size: No Module Installed

        Size: No Module Installed

        Size: No Module Installed

        Size: No Module Installed

2、查看最大支持内存数

dmidecode|grep -P 'Maximum\s+Capacity'

eg: Maximum Capacity: 16 GB
3、查看槽位上内存的速率，没插就是unknown。

dmidecode|grep -A16 "Memory Device"|grep 'Speed'

 查看CPU

1.1 查看CPU个数

# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l

2 **uniq命令：删除重复行;wc –l命令：统计行数**

1.2 查看CPU核数

# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores : 4

1.3 查看CPU型号

# cat /proc/cpuinfo | grep 'model name' |uniq
model name : Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

总结：该服务器有2个4核CPU，型号Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
