     Linux下如何查看系统启动时间和运行时间

    1.uptime命令
    输出:16:11:40 up 59 days, 4:21, 2 users, load average: 0.00, 0.01, 0.00

    2.查看/proc/uptime文件计算系统启动时间
    cat /proc/uptime
    输出: 5113396.94 575949.85
    第一数字即是系统已运行的时间5113396.94 秒,运用系统工具date即可算出系统启动时间

    代码: 全选
    date -d "$(awk -F. '{print $1}' /proc/uptime) second ago" +"%Y-%m-%d %H:%M:%S"


    输出: 2008-11-09 11:50:31

    3.查看/proc/uptime文件计算系统运行时间

    代码: 全选
    cat /proc/uptime| awk -F. '{run_days=$1 / 86400;run_hour=($1 % 86400)/3600;run_minute=($1 % 3600)/60;run_second=$1 % 60;printf("系统已运行:%d天%d时%d分%d秒",run_days,run_hour,run_minute,run_second)}'


    输出:系统已运行:59天4时13分9秒

    Linux 查询服务器序列号命令

    例:dmidecode -t 1
    查看服务器型号:dmidecode | grep 'Product Name'
    查看主板的序列号:dmidecode |grep 'Serial Number'
    查看系统序列号:dmidecode -s system-serial-number
    查看内存信息:dmidecode -t memory
    查看OEM信息:dmidecode -t 11
