拿到一个系统，肯定要看看系统配置，linux下看配置，可没有windows那么直观。你只能一个一个查看。
一：cpu [root@srv /]# more /proc/cpuinfo | grep "model name" model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz [root@srv /]# grep "model name" /proc/cpuinfo model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz [root@srv /]# grep "model name" /proc/cpuinfo | cut -f2 -d: Intel(R) Xeon(R) CPU X3220 @ 2.40GHz Intel(R) Xeon(R) CPU X3220 @ 2.40GHz Intel(R) Xeon(R) CPU X3220 @ 2.40GHz Intel(R) Xeon(R) CPU X3220 @ 2.40GHz 二：内存 [root@srv /]# grep MemTotal /proc/meminfo MemTotal: 614400 kB [root@srv /]# free -m total used free shared buffers cached Mem: 600 23 576 0 0 0 -/+ buffers/cache: 23 576 Swap: 0 0 0 [root@srv /]# free -m |grep "Mem" | awk '{print $2}' 600 三：查看CPU位数(32 or 64) [root@srv /]# getconf LONG_BIT 32 四：查看linux版本 [root@srv /]# more /etc/redhat-release CentOS release 5 (Final) [root@srv /]# more /etc/issue CentOS release 5 (Final) Kernel \r on an \m [root@srv /]# more /proc/version Linux version 2.6.18-92.1.18.el5.028stab060.2PAE (root@rhel5-32-build-xemul) (gc c version 4.1.2 20071124 (Red Hat 4.1.2-42)) #1 SMP Tue Jan 13 12:31:30 MSK 2009 五：查看内核版本 [root@srv /]# uname -r 2.6.18-92.1.18.el5.028stab060.2PAE [root@srv /]# uname -a Linux srv.eddiechen.cn 2.6.18-92.1.18.el5.028stab060.2PAE #1 SMP Tue Jan 13 12:31:30 MSK 2009 i686 i686 i386 GNU/Linux 六：查看时区 [root@srv /]# date -R Wed, 25 Feb 2009 02:20:50 +0000 [root@srv /]# mv /etc/localtime /etc/localtime.save [root@srv /]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime [root@srv /]# date -R Wed, 25 Feb 2009 10:24:26 +0800 七：主机名 [root@srv /]# hostname srv.eddiechen.cn 八：查看selinux情况 [root@srv /]# sestatus SELinux status: disabled 九：网络 IP [root@srv /]# ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}' 207.154.202.216 网关 [root@srv /]# cat /etc/sysconfig/network NETWORKING="yes" GATEWAY="192.0.2.1" HOSTNAME="srv.eddiechen.cn" dns [root@srv /]# cat /etc/resolv.conf nameserver 208.74.168.131 nameserver 208.74.168.132 nameserver 4.2.2.1 十：已经安装的软件包 [root@srv /]# rpm -qa | wc -l 197 [root@srv /]# yum list installed | wc -l 198 十一：磁盘和分区 [root@srv /]# df -h Filesystem Size Used Avail Use % Mounted on /dev/simfs 10G 353M 9.7G 4% / [root@srv /]# du -sh 353M [root@srv /]# du /etc -sh 4.6M /etc |
