查看linux服务器主板型号，cpu型号，内存大小，内存条数量

因为种种原来，我们可能需要查看linux服务器主板型号，cpu型号，内存大小，内存条数量等。因为服务器使用raid卡，平常查看硬盘信息的命令还不能用，待后面补充！

查看主板型号

代码如下

复制代码

# dmidecode |grep -A 8 "System Information"   System Information          Manufacturer:  Dell                             Product Name:  CS24-TY                          Version:  A00                              Serial Number:  24Z1NL1                          UUID:  2656CFCF-887A-0010-BBD8-00269E9C46DC          Wake-up Type: Power Switch          SKU Number: To Be Filled By O.E.M.          Family: Server上网查DELL CS24-TY，找到说主板型号是DELL  PowerEdge C1100

查看内存

# free -m                total        used       free      shared    buffers     cached  Mem:          32103       31803        300           0         217        953  -/+ buffers/cache:       30632       1471  Swap:         16383         476      15907

查看内存条数

[root@localhost ~]# dmidecode -t memory|grep Size          Size: 8192 MB Type:  Other Speed: 1333 MHz          Size: No Module Installed          Size: 8192 MB

查看硬盘大小，分区

[root@localhost ~]# df -h  Filesystem             Size  Used Avail Use% Mounted on  /dev/sda3              119G   17G   96G  15% /  tmpfs                   16G     0   16G   0% /dev/shm  /dev/sda1               97M   32M   61M  35% /boot

查看raid卡，raid卡为DELLPERC 6/i

[root@localhost ~]# dmesg |grep -i raid  dracut: rd_NO_DM: removing DM RAID activation  dracut: rd_NO_MD: removing MD RAID activation  ahci 0000:00:1f.2: AHCI 0001.0200 32 slots 6 ports 3 Gbps 0x3f impl RAID mode  megaraid_sas 0000:04:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16  megaraid_sas 0000:04:00.0: setting latency timer to 64  megaraid_sas: fw state:c0000000  scsi6 : LSI SAS based MegaRAID driver  [root@localhost ~]# cat /proc/scsi/scsi  Attached devices:  Host: scsi6 Channel: 02 Id: 00 Lun: 00    Vendor: DELL     Model: PERC  6/i         Rev: 1.11    Type:    Direct-Access                     ANSI  SCSI revision: 05

查看网卡

[root@localhost ~]# lspci | grep -i 'eth'  05:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network  Connection (rev 01)  05:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network  Connection (rev 01)

查看21号网络流量

# sar -n DEV  -f /var/log/sa/sa21 |grep eth|less

查看板载显示信息

[root@localhost ~]# dmidecode |grep -A 5 "On Board Device  Information"  On Board Device Information          Type: Video          Status: Enabled          Description:  AST2050 VGA

内存槽及内存条：

# dmidecode |grep -A16 "Memory Device$"

查看cpu型号，主频
