Abnormal phenomena
Port 541 cannot be started to monitor because ordinary users can only start ports larger than 1024. Only the root user has the permission to start ports below 1024.
Supervisor changes the startup user
This changes the supervisor process from an ordinary user to a root user.

root user
If the supervisor is started directly without passing relevant parameters, the startup will fail.
Only the supervisor process itself is started by root, and the supervisor management process can be started by the root user.
Supervisor restarts normally
