    cat /etc/issue

# 2、查看系统信息 #

uname -a
    
    uname --help
      -a, --all                print all information, in the following order,
                                 except omit -p and -i if unknown:
      -s, --kernel-name        print the kernel name
      -n, --nodename           print the network node hostname
      -r, --kernel-release     print the kernel release
      -v, --kernel-version     print the kernel version
      -m, --machine            print the machine hardware name
      -p, --processor          print the processor type or "unknown"
      -i, --hardware-platform  print the hardware platform or "unknown"
      -o, --operating-system   print the operating system
          --help     display this help and exit
          --version  output version information and exit

# 3、查看linux是64位还是32位 #

五种方式：

getconf LONG_BIT
    
    uname -m
    
    arch
    
    file /sbin/init
    
    #结果大于1就是64位，否则32位
    cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l

# 4、查看cpu配置 #

lscpu

# 5、查看ip,hostname,cpu,memory,disk #

ip a
    ip=`ifconfig|egrep -o "\<(([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\>"|head -1`
    echo ip=$ip
    
    hostname=`hostname`
    echo "主机名=$hostname"
    cores=`cat /proc/cpuinfo| grep "processor"| wc -l`
    echo "逻辑cpu个数=$cores"
    
    memory=`free -h|awk 'NR==2{print $2}'`
    echo "内存大小=$memory"
    
    disk=`lsblk -db|awk 'NR>1{sum+=$4} END {print sum/1024/1024/1024}'`
    echo "磁盘总大小=${disk}G"
