puppet agent is not performing according to puppet master

Hi, I'm trying to configure puppet server and client. My server's `puppet.conf` looks like

[main]
    logdir = /var/log/puppet
    rundir = /var/run/puppet
    ssldir = $vardir/ssl
    dns_alt_names = puppet,rahul.example.com
[agent]
    classfile = $vardir/classes.txt
    localconfig = $vardir/localconfig

My Client's puppet.conf looks like,

[main]
    server = rahul.example.com
    logdir = /var/log/puppet
    rundir = /var/run/puppet
    ssldir = $vardir/ssl

[agent]
    classfile = $vardir/classes.txt
    localconfig = $vardir/localconfig
    runinterval = 0

My manifest looks like, `site.pp`

node 'client.example.com' {

        file { '/etc/motd':
                content => "This is configured via Puppet Server\n",
        }

        package { 'vsftpd':
                ensure => present,
        }

        user { 'ironman':
                ensure => present,
                comment => 'Iron Man',
                home => '/home/ironman',
                managehome => true,
                password => $6$poTX4MwAOs0sA3YN$CkTVJZGoiaybS9EAe1VotzJ5NC/x1mU32YHu.H9Gn77z9LxrLnybREeIMo5vKdN2KPWm/jNXEGxNudgthzAQs.
}

after that I restarted `puppetmaster` service at server, and puppet at client still there is no such user created, no vsftpd installed, nothing written to `/etc/motd` file. Please help me out, I'm new to Puppet.
