rsync:failed to exec SSH solution appears when using rsync

On a streamlined CentOS VPS, install a rsync to find that the problem is very large synchronization when prompted by the following error

Rsync:failed to exec ssh:no such file or directory (2)
rsync Error:error in IPC Code (code) at pipe.c [sender=3.0.6]
Rsync:connection unexpectedly closed (0 bytes received so far) [sender]
rsync Error:error in IPC Code (code) at io.c [sender=3.0.6]

What's more, the information found on the Internet is basically crap or nobody gives a solution.

Find a solution on a foreign site:

Rsync:failed to exec ssh:no such file or directory (2)
rsync Error:error in IPC Code (code) at pipe.c [sender=3.0.6]
Rsync:connection unexpectedly closed (0 bytes received so far) [sender]
rsync Error:error in IPC Code (code) at io.c [sender=3.0.6]
