When creating a small farm search topology, does the web application get created on the Central Admin server or the other server?

Question

I'm fairly new to Sharepoint and I'm trying to set up a small farm search topology such as the following: https://technet.microsoft.com/en-us/library/gg750251(v=office.14).aspx . I don't believe I set it up right, however. I have two servers - we'll call them SPCrawl and SPSearch. According to the guide linked above, the SPCrawl server should host Central Admin and perform the crawling. I believe I messed up because I created the web application on SPCrawl, but then created the Enterprise Search Center and linked it to the web application on SPCrawl.

Basically, my question is this: should I have created the web application on SPSearch instead? I'm just wondering because unless I'm misinterpreting something, it doesn't seem like SPSearch is actually doing anything. I just want confirmation before changing anything. Thank you!

If hardware on all server are same then it really doesnot matter, You can change the server role.

Central Admin will host on the 1st server in the farm( on which you run the Config wizard & create config db).

By default all web apps created on the Central Admin server but you can change the AAM to change it to different server.Once you created the Web Application just Change the AAM setting then you all set.
