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。
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.
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
