Linux自动检测进程是否存活，如果挂掉自动拉起

以 jupyter 服务为例

1、检测脚本

vim /home/ailab/bin/check_ailab.sh

#!/bin/bash PID=$(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！
