使用公钥编写 SCP 脚本

我需要配置一个脚本来将一些文件从一个 Ubuntu 服务器复制到另一个。远程服务器上的authorized_keys中允许使用密钥。

我正在尝试配置此脚本：

#!/bin/sh

#Monitoring
for i in 192.168.0.10 192.168.0.11;
do
  su user1 -l -c "scp -oStrictHostKeyChecking=accept-new -oPasswordAuthentication=no -oBindAddress=0.0.0.0 -q -r /tmp/log/*log user1@${i}:/data/logs/"
done

我收到此日志：

Executing: program /usr/bin/ssh host 192.168.0.10, user user1, command scp -v -r -d -t /data/logs/
lost connection

我可以使用我在远程服务器上的帐户进行连接。但是当我尝试运行脚本时，日志是：
