/usr/bin/rsync
都正常啊。
解决bash: rsync: command not found – hao32的个人日志
-》才明白：
原来是远程服务器中没有安装rsync。。。
所以需要先去远程服务器中安装rsync，本地rsync才能使用。
[root@iZbp1d6nnllpn4f211pl59Z uapp]# which rsync
/usr/bin/which: no rsync in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
[root@iZbp1d6nnllpn4f211pl59Z uapp]# yum -y install rsync

然后本地再去试试rsync，就可以了：
【总结】
本地的Mac中，已经安装了rsync了，但是终端中执行rsync报错：
bash: rsync: 未找到命令
原因是：
使用rsync的前提是：本地电脑和远程服务器都安装了rsync才可以。
而此处远程服务器中没有安装rsync，所以报错。
办法：
给远程服务器，此处是CentOS，中安装rsync即可：
yum -y install rsync
