vim - The following problem occurred when setting up a PHP environment

After the installation is completed, open 127.0.0.1:2222 and prompt me:

SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.8
Protocol mismatch.

What’s the problem?
I have php/apache/mysql, I have reloaded it but it still doesn’t work
I have created a new one

<code><?php
phpinfo();
?></code>

Just install openssh-server and you’re good to go
