我认为这一定是权限导致运行rsyncd守护程序的用户出现这种情况，因为手动执行的rsync命令工作得很好。
谢谢。
答案1
首先是本地版本。
我在测试脚本中省略了“--remove-source-files”：
[root@centos7 rsync_task]# pwd
/root/rsync_task
[root@centos7 rsync_task]# ls -la backup.sh
-rw-r--r-x 1 root root 259 Feb 13 01:15 backup.sh
[root@centos7 rsync_task]# cat backup.sh
#!/bin/sh
echo "List files in src: "$(ls /mnt/backup_src)
/usr/bin/rsync --chmod=u=rwx,g=rwx,o=rwx -r -zvh --log-file=/var/log/rsync_activity.log /mnt/backup_src/* /mnt/backup_dst
echo `date` ' Rsync - File(s) moved to NFS Share' >> /var/log/rsync_backup.log
服务文件：
[root@centos7 rsync_task]# ls -lah /etc/systemd/system/rsync_backup.service

让我们检查一下备份：
[root@centos7 mnt]# ls backup_dst
file1 file2 file3 file4 file5
复制到 NFS 共享（“debian9”用作 NFS 服务器）。
NFS 服务器配置：
root@debian9:~/backups# pwd

检查 NFS 服务器：
root@debian9:~/backups# pwd
/root/backups
root@debian9:~/backups# ls
file1 file2 file3 file4 file5
最后，尝试使用将在“debian9”主机中运行的“rsyncd”：

对备份脚本进行少量更改：

答案2
对于它的价值，我会检查脚本文件 /usr/etc/UHS_FolderMonitor.ksh 上的 SELinux 上下文。我在使用 rsync 的 systemd 单元文件中遇到了类似的问题。
另请参阅 man 8 rsync_selinux （selinux-policy-doc 包）以获取有用的布尔值。
