bash: rsync: 未找到命令

今天学习了rsync的同步操作，本打算往服务器同步一些数据，于是报了一下错误：

bash: rsync: 未找到命令

rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at /BuildRoot/Library/Caches/com.apple.xbs/Sources/rsync/rsync-52/rsync/io.c(453) [sender=2.6.9]

通过排查客户机和服务器，发现居然是服务器端没有安装rsync。

在服务器端安装rsync即可：

[root@localhost ~]# yum -y install rsync

注：

同步与被同步机器都要安装rsync

否则会出现报错

bash: rsync: command not found
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: remote command not found (code 127) at io.c(226) [sender=3.1.2]
