[root@backup tmp]# rsync -avz /etc/hosts -e 'ssh -p 22' root@172.16.1.5:/tmp/
rsync: Failed to exec ssh: No such file or directory (2)
rsync error: error in IPC code (code 14) at pipe.c(84) [sender=3.0.6]
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(600) [sender=3.0.6]
从网上找打解决方法讲是没有安装openssh客户端，然后安装尝试一下
[root@backup tmp]# yum -y install openssh-clients.x86_64
安装完成之后有执行一次，发现错误提示变了，说明刚才那个错误已解决然后开始解决新的报错问题
从本地服务器上推送文件到172.16.1.5这台服务器上，发现一直提示这个错误信息。然后在网上找各种解决方法，最终得以解决。
[root@backup tmp]# rsync -avz /tmp/hosts -e 'ssh -p 22' root@172.16.1.5:/tmp/
root@172.16.1.5's password:
bash: rsync: command not found
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(600) [sender=3.0.6]
造成这种原因是因为172.16.1.5这台服务上没有安装rsync这个软件包，安装后得以解决
[root@backup tmp]# rsync -avz /tmp/hosts -e 'ssh -p 22' root@172.16.1.5:/tmp/
