解决：
/etc/rsyncd.conf配置模板：
[root@test181 ~]# cat /etc/rsyncd.conf
uid = rsync
gid = rsync
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/ryncd.log

ingnore errors
read only = false
list = false
hosts allow = 10.0.0.0/24
hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password
原因：/ggp的权限不正确。
[root@ggp ~]# chown -R rsync.rsync /ggp
再次执行成功。
