使用 tuptime 工具查看 Linux 服务器系统的开机时间的历史和统计 ================================================================================ 你可以使用下面的工具来查看 Linux 或类 Unix 系统运行了多长时间: - uptime : 告诉你服务器运行了多长的时间。 - lastt : 显示重启和关机时间。 - tuptime : 报告系统的运行时间历史和运行时间统计,这是指重启之间的运行时间。和 uptime 命令类似,不过输出结果更有意思。 ### 找出系统上次重启时间和日期 ### 你[可以使用下面的命令来获取Linux操作系统的上次重启和关机时间及日期][1](在OSX/类Unix系统上也可以用): ### 显示系统重启和关机时间 who -b last reboot last shutdown ### 开机信息 uptime cat /proc/uptime awk '{ print "up " $1 /60 " minutes"}' /proc/uptime w **样例输出:** ![Fig.01: Various Linux commands in action to find out the server uptime](http://s0.cyberciti.org/uploads/cms/2015/09/uptime-w-awk-outputs.jpg) *图01:用于找出服务器开机时间的多个Linux命令* ###跟 tuptime 问打个招呼吧### tuptime 命令行工具可以报告基于 Linux 的系统上的下列信息: 1. 系统启动次数统计 2. 注册首次启动时间(也就是安装时间) 3. 正常关机和意外关机统计 4. 平均开机时间和故障停机时间 5. 当前开机时间 6. 首次启动以来的开机和故障停机率 7. 累积系统开机时间、故障停机时间和合计 8. 报告每次启动、开机时间、关机和故障停机时间 #### 安装 #### 输入[下面的命令来克隆 git 仓库到 Linux 系统中][2]: $ cd /tmp $ git clone https://github.com/rfrail3/tuptime.git $ ls $ cd tuptime $ ls **样例输出:** ![Fig.02: Cloning a git repo](http://s0.cyberciti.org/uploads/cms/2015/09/git-install-tuptime.jpg) *图02:克隆git仓库* 确保你安装了带有 sys,optparse,os,re,string,sqlite3,datetime,disutils 和 locale 模块的 Python v2.7。 你可以像下面这样来安装: $ sudo tuptime-install.sh 或者,可以手工安装(基于 systemd 或非 systemd ): $ sudo cp /tmp/tuptime/latest/cron.d/tuptime /etc/cron.d/tuptime 如果系统是systemd的,拷贝服务文件并启用: $ sudo cp /tmp/tuptime/latest/systemd/tuptime.service /lib/systemd/system/ $ sudo systemctl enable tuptime.service 如果系统不是systemd的,拷贝初始化文件: $ sudo cp /tmp/tuptime/latest/init.d/tuptime.init.d-debian7 /etc/init.d/tuptime $ sudo update-rc.d tuptime defaults ####运行#### 只需输入以下命令: $ sudo tuptime **样例输出:** ![Fig.03: tuptime in action](http://s0.cyberciti.org/uploads/cms/2015/09/tuptime-output.jpg) *图03:tuptime工作中* 在一次更新内核后,我重启了系统,然后再次输入了同样的命令: $ sudo tuptime System startups: 2 since 03:52:16 PM 08/21/2015 System shutdowns: 1 ok - 0 bad Average uptime: 7 days, 16 hours, 48 minutes and 3 seconds Average downtime: 2 hours, 30 minutes and 5 seconds Current uptime: 5 minutes and 28 seconds since 06:23:06 AM 09/06/2015 Uptime rate: 98.66 % Downtime rate: 1.34 % System uptime: 15 days, 9 hours, 36 minutes and 7 seconds System downtime: 5 hours, 0 minutes and 11 seconds System life: 15 days, 14 hours, 36 minutes and 18 seconds 你可以像下面这样修改日期和时间格式: $ sudo tuptime -d '%H:%M:%S %m-%d-%Y' **样例输出:** System startups: 1 since 15:52:16 08-21-2015 System shutdowns: 0 ok - 0 bad Average uptime: 15 days, 9 hours, 21 minutes and 19 seconds Average downtime: 0 seconds Current uptime: 15 days, 9 hours, 21 minutes and 19 seconds since 15:52:16 08-21-2015 Uptime rate: 100.0 % Downtime rate: 0.0 % System uptime: 15 days, 9 hours, 21 minutes and 19 seconds System downtime: 0 seconds System life: 15 days, 9 hours, 21 minutes and 19 seconds 计算每次启动、开机时间、关机和故障停机时间: $ sudo tuptime -e **样例输出:** Startup: 1 at 03:52:16 PM 08/21/2015 Uptime: 15 days, 9 hours, 22 minutes and 33 seconds System startups: 1 since 03:52:16 PM 08/21/2015 System shutdowns: 0 ok - 0 bad Average uptime: 15 days, 9 hours, 22 minutes and 33 seconds Average downtime: 0 seconds Current uptime: 15 days, 9 hours, 22 minutes and 33 seconds since 03:52:16 PM 08/21/2015 Uptime rate: 100.0 % Downtime rate: 0.0 % System uptime: 15 days, 9 hours, 22 minutes and 33 seconds System downtime: 0 seconds System life: 15 days, 9 hours, 22 minutes and 33 seconds -------------------------------------------------------------------------------- via: http://www.cyberciti.biz/hardware/howto-see-historical-statistical-uptime-on-linux-server/ 作者:Vivek Gite 译者:[GOLinux](https://github.com/GOLinux) 校对:[wxy](https://github.com/wxy) 本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译,[Linux中国](https://linux.cn/) 荣誉推出 [1]:http://www.cyberciti.biz/hardware/howto-see-historical-statistical-uptime-on-linux-server/ [2]:http://www.cyberciti.biz/faq/debian-ubunut-linux-download-a-git-repository/
