Puppet: relations between resources on different nodes

Question

I know that we can indicate a relationship between resources that determines the deployment order. But is it possible to create a relationship between resources on different nodes in Puppet?

For example, I have an apache web server in node A and a mysql server in node B. I want to start mysql first before starting the apache web server. How can I put it in puppet language?

---

I tried the following codes:

node ‘host1’ {
  @@service { ‘mysql’:
    ensure => running,
    tag => ‘host1-mysql’,
  }
}
node ‘host2’ {
  service { ‘apache2’:
    ensure => running,
  }
  Service<<| tag == ‘host1-mysql’ |>> -> Service[‘apache2’]
}

But this did not work - a compilation error occurred. Any other solution?
