连续运行套接字的初始化脚本

Question

我使用 init-script 作为守护进程运行我的脚本（套接字）：

   #!/bin/bash



### BEGIN INIT INFO
 # Provides:          sock_serv
 # Required-Start:    $local_fs $syslog $remote_fs
 # Required-Stop:     $local_fs $syslog $remote_fs
 # Default-Start:     2 3 4 5
 # Default-Stop:      0 1 6
 # Short-Description: sock_servservice
 # Description:       Run sock_serv service
 ### END INIT INFO

 # Carry out specific functions when asked to by the system
 case "$1" in
   start)
     echo "Starting sock_serv..."
     if sudo -u root bash -c 'cd ~/mypath/ && python3 sock_serv.py &> /dev/null &' ; then
       echo "OK"
     else
       echo "Error: can't start "
     fi
   ;;
stop)
   echo "Stopping sock_serv..."
   if sudo -u root bash -c 'cd ~/mypath/ && python3 stop_sock_serv.py &>/dev/null &'; then
   # sleep 2
      echo "OK"
   else
      echo "Error: can't stop "
   fi
   ;;
   *)
echo "Usage: /etc/init.d/sock_serv {start|stop}"
exit 1
;;
esac

我在sock_serv模块中使用循环Select来接收来自不同客户端的消息。

我可以运行我的sock_serv，但几个小时后sock_serv监听任何端口（停止）

当我运行service sock_serv statusbevor 并在 sock_serv 停止后我得到：

     sock_serv.service - LSB: sock_serv service
     Loaded: loaded (/etc/init.d/sock_serv; generated)

我希望 sock_serv 仍然持续运行。谢谢
