1. 查看系统内核版本命令：

uname -a

more /etc/*release more /etc/redhat-release

more /proc/version

output

＃uname -a

2. 查看cpu信息

grep "model name" /proc/cpuinfo

more /proc/cpuinfo

＃ grep "model name" /proc/cpuinfo

3. 查看cpu的位数

getconf LONG_BIT

＃ getconf LONG_BIT

gcc –version

 

5. 查看内存信息

more /proc/meminfo

grep MemTotal /proc/meminfo
