后来尝试重新写配置文件,发现成功了

[root@backup ~]# vim /etc/rsyncd.conf

uid = rsync

gid = rsync

port = 873

fake super = yes

use chroot = no

max connections = 200

timeout = 600

ignore errors

read only = false

list = false

auth users = rsync_backup

secrets file = /etc/rsync.passwd

log file = /var/log/rsyncd.log
