启动时间相关
1. systemd-analyze命令
# 开机启动时间
root@TangramBook:~# systemd-analyze
Startup finished in 5.843s (firmware) + 52ms (loader) + 5.113s (kernel) + 8.231s (userspace) = 19.241s
graphical.target reached after 8.224s in userspace
# 服务启动时间
root@TangramBook:~# systemd-analyze blame
3.868s cic.service
3.433s NetworkManager-wait-online.service
...... 省略部分 ......

# 系统启动和运行（正常运行时间）以来的持续时间
root@TangramBook:~# uptime -p
up 22 hours, 23 minutes
# 系统启动和运行（正常运行时间）以来的持续时间
root@TangramBook:~# uptime -s
2. uptime命令
# 1. uptime命令
root@TangramBook:~# uptime
15:03:48 up 2:35, 2 users, load average: 0.38, 0.16, 0.20
# 2.查看/proc/uptime文件计算系统启动时间
root@TangramBook:~# cat /proc/uptime
9339.47 73723.60
# ----运用系统工具date即可算出系统启动时间
root@TangramBook:~# date -d "$(awk -F. '{print $1}' /proc/uptime) second ago" +"%Y-%m-%d %H:%M:%S"
2020-04-01 12:28:20
# 3.查看/proc/uptime文件计算系统运行时间
root@TangramBook:~# 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)}'
系统已运行：0天2时36分23秒
3. who 命令
who -b 查看最后一次系统启动的时间。
who -r 查看当前系统运行时间
# 上次启动时间
root@TangramBook:~# who -b
系统引导 2020-04-01 20:28
# 当前运行时间
root@TangramBook:~# who -r
运行级别 5 2020-04-01 20:29
# 历史启动时间
root@TangramBook:~# last reboot
wtmp begins Wed Apr 1 15:03:35 2020
# 最后一次启动时间
root@TangramBook:~# last reboot | head -1
4. 通过脚本实现（sysinfo）
sysinfo结构
sysinfo结构保持了系统启动后的信息，主要包括启动到现在的时间，可用内存空间、共享内存空间、进程的数目等。man sysinfo得到结果如下所示
struct sysinfo {
long uptime; /* Seconds since boot */
unsigned long loads[3]; /* 1, 5, and 15 minute load averages */
unsigned long totalram; /* Total usable main memory size */
unsigned long freeram; /* Available memory size */
unsigned long sharedram; /* Amount of shared memory */
unsigned long bufferram; /* Memory used by buffers */
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* swap space still available */
unsigned short procs; /* Number of current processes */
char _f[22]; /* Pads structure to 64 bytes */
};
获取系统启动时间
通过sysinfo获取系统启动到现在的秒数，用当前时间减去这个秒数即系统的启动时间。程序如下所示：
#include <stdio.h>
#include <sys/sysinfo.h>
#include <time.h>
#include <errno.h>
static int print_system_boot_time()
{
struct sysinfo info;
time_t cur_time = 0;
time_t boot_time = 0;
struct tm *ptm = NULL;
if (sysinfo(&info)) {
fprintf(stderr, "Failed to get sysinfo, errno:%u, reason:%s\n",
errno, strerror(errno));
return -1;
}
time(&cur_time);
if (cur_time > info.uptime) {
boot_time = cur_time - info.uptime;
}
else {
boot_time = info.uptime - cur_time;
}
ptm = gmtime(&boot_time);
printf("System boot time: %d-%-d-%d %d:%d:%d\n", ptm->tm_year + 1900,
ptm->tm_mon + 1, ptm->tm_mday, ptm->tm_hour, ptm->tm_min, ptm->tm_sec);
return 0;
}
int main()
{
if (print_system_boot_time() != 0) {
return -1;
}
return 0;
}
# 1.uptime命令
root@TangramBook:~# ./time
System boot time: 2020-04-01 20:28:38
