以 jupyter 服务为例

1、检测脚本

vim /home/ailab/bin/check_ailab.sh

#!/bin/bashPID=$(ps -ef|grep -v grep|grep "jupyter" |awk '{print $2}')# 检查进程是否存在
if [ -z "$PID" ]; then# 进程不存在，启动进程echo "Jupyter Notebook is not running. Starting it..."# 这里替换为你启动进程的命令/data1/ailab/run/start.sh &
else# 进程存在，输出进程ID# echo -e "Jupyter Notebook is running with PID: \n${PID}"echo "Jupyter Notebook is running with PID: ${PID}"
fi

2、定时任务 Crontab

每分钟检测一次，也可以设置每秒检测一次

[ailab@localhost ~]$ crontab -l
* * * * * /home/ailab/bin/check_ailab.sh
[ailab@localhost ~]$

我们下期见，拜拜！
