python程序自动重启脚本的编写与使用

1.脚本内容：

#!/bin/bash

TARGETS=("/pg_project/server8190.py" "/pg_project/websocket.py"
 "/pg_project/status.py" "/pg_project/control_status.py"
  "/pg_project/web.py" "/pg_project/upload.py")

for target in "${TARGETS[@]}"
do
    PID=$(ps aux | grep -v grep | grep $target | awk '{print $2}')
    # 判断进程是否运行
    if [ -z "$PID" ]
    then
        echo "因进程异常终止，重启 $target 服务" >> /home/liuyang/restart.log
        nohup /usr/bin/python3.7 $target >> /home/liuyang/restart.log 2>&1 &
    fi

done

2.设置定时任务，每分钟执行一次

crontab -e

*/1 * * * * /home/liuyang/restart.sh

3.重启定时服务

sudo service cron restart
