linux - 关于守护进程处理任务

Question

百度了一下，一般守护进程的工作形式是：监听端口，有数据来了就fork()子进程对数据进行处理。

小弟现在需要编写一个分布式任务处理的程序，这个任务手工执行的方式是：
1、普通用户登录server；
2、手动加载profile以及挂载网络文件系统；
3、执行程序（因为程序在NFS上面才有）。

这种任务执行方式，怎么用守护进程实现呢？毕竟手工执行任务需要以普通用户身份登录控制终端，而守护进程属于超级用户，并且是不属于某个控制终端的。
问题是守护进程怎么模拟任务手工执行这三个步骤？因为这个任务需要某个用户控制终端所属的进程来执行。

Answer 1

I don’t understand what you mean. Port monitoring does not distinguish between user permissions. Ordinary users can also send sockets to daemons created by super users. I don’t know where you can’t figure it out.

Answer 2

The above two parts can be done with shell programming
I won’t go into details if ssh is configured and used to log in with a certificate.
Ssh can be followed directly by the file name, which is to execute a certain command after the login is completed
As for hanging on the network file system and executing a specific program, it can be written in the command script executed when logging in
