Rsync server synchronization error for help

Rsync server synchronization error help-Linux general technology-Linux technology and application information, the following is a detailed description. [I = s] This post was last edited by szfhx

My ubuntu server (192.168.2.99) can use rsync to back up the directory locally, for example:
Su
Rsync-avz -- delete -- exclude-from = "/home/hr/back/paicu"/home/back/
Both the server and client create hr and fhx users.

Enter the following command on the client 192.168.2.8:
Su # The following command error prompts are the same for root, hr, or fhx users. It seems that the password file created on the client is useless.
Rsync-avz -- password-file =/etc/rsyncd. scrt hr@192.168.2.99: homehr/home/hr or
Rsync-avz -- password-file =/etc/rsyncd. scrt fhx@192.168.2.99: homehr/home/fhx
The error message is as follows:
Password file must not be other-accessible
Continuing without password file
Password:
@ ERROR: auth failed on module homehr
Rsync error: error starting client-server protocol (code 5) at main. c (1521) [runner ER = 3.0.6]
However, you can run the following command:
Hr@192.168.2.99:/home/hr
Does ubuntu rsync fail to use: homehr (Module name? -- Password-file =/etc/rsyncd. scrt password file Settings (password-Free input settings) do not work?
How can this problem be solved?

Appendix: My rsync settings for 192.168.2.99 Server:
Su
Vim/etc/rsyncd. conf
# [Globale]
Strict modes = yes
# Check passwd file
Port = 873
# Default port
Logfile =/var/log/rsyncd. log
Pidfile =/var/run/rsyncd. pid
Max connections = 4
# [Modules]
[Homehr]
# Backup module
Uid = root
Gid = root
Path =/home
# Directory to be backed up
Read only = no
Host allow = 192.168.2.8
Auth users = hr, fhx
Secrets file =/etc/rsyncd. scrt

Password File:
Vim/etc/rsyncd. scrt
Hr: 123.
Fhx: 123
Chmod 600/etc/rsyncd. scrt

Start the Service (if a firewall is enabled, allow port 873 to pass through)
Rsync -- daemon -- config =/etc/rsyncd. conf

Configure the client (192.168.2.8) rsync ubuntu is installed by default
Create or modify a password file
Su
Vim/etc/rsyncd. scrt
The file content is the same as the client file content
Chmod 600/etc/rsyncd. scrt
