一：檢視cpu
- more /proc/cpuinfo | grep "model name"
- grep "model name" /proc/cpuinfo
如果覺得需要看的更加舒服
- grep "model name" /proc/cpuinfo | cut -f2 -d:
怎麼樣，linux的命令就要這樣熟悉。
二：檢視內
- [[email protected] ~]# grep MemTotal /proc/meminfo
- [[email protected] ~]# grep MemTotal /proc/meminfo | cut -f2 -d:
- [[email protected]~]# free -m |grep "Mem" | awk '{print $2}'
- [[email protected] ~]# free -m
三：檢視cpu是32位還是64位
檢視CPU位數(32 or 64)
- [[email protected] ~]# getconf LONG_BIT
- [[email protected] ~]# echo $HOSTTYPE
- [[email protected] ~]# uname -a
四：檢視當前linux的版本
- [[email protected] ~]# more /etc/redhat-release
- [[email protected] ~]# cat /etc/redhat-release
五：檢視核心版本
- [[email protected] ~]# uname -r
- [[email protected] ~]# uname -a
六：檢視當前時間
- [[email protected] ~]# date
七：檢視硬碟和分割槽
- [[email protected] ~]# df -h
- [[email protected] ~]# fdisk -l
也可以檢視分割槽
- [[email protected] home]# du -sh
可以看到全部佔用的空間
- [[email protected] home]# du /var/www -sh
可以看到這個目錄的大小
八：檢視安裝的軟體包
檢視系統安裝的時候裝的軟體包
- cat -n /root/install.log
- more /root/install.log | wc -l
檢視現在已經安裝了那些軟體包
- [[email protected] home]# rpm -qa
- .......................
- .......................
- .......................
- .......................
- .......................
- [[email protected] home]# rpm -qa | wc -l
- [[email protected] home]# yum list installed | wc -l
不過很奇怪，我通過rpm，和yum這兩種方式查詢的安裝軟體包，數量並不一樣。沒有找到原因。
