Hi all,

So I know how to do this for the most part, but I’ve got two servers that when I have to reboot them, one needs to be done before the other and cannot before a specific port comes available. That port is only accessible from that second server, not the ansible server itself. Does that make sense?

Is there a way that I can create a playbook that will do what I’m describing?

ie

Reboot server1

Reboot server2 when tcp/3306 comes available on server1. **tcp/3306 is only open to server2.**

Use the reboot module on server1, it will wait for the server to be available again.  
Then in the next task you can use the wait\_for module on server2 to check the port 3306.

Pseudo code for 2 play in one playbook.

- hosts: server1  
&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- reboot:

- hosts: server2  
&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- wait\_for:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;host: server1  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;port: 3306  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;state: started

&nbsp;&nbsp;&nbsp;&nbsp;- reboot:

or in one play

- hosts: server1,server2  
&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- reboot:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: inventory\_hostname == "server1"

&nbsp;&nbsp;&nbsp;&nbsp;- wait\_for:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;host: server1  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;port: 3306  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;state: started  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: inventory\_hostname == "server2"

&nbsp;&nbsp;&nbsp;&nbsp;- reboot:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: inventory\_hostname == "server2"

Doesn’t this use the ansible server running the playbook to check if the port is open?
