Enable chef-server-webui

Hi .

I was running my chef w/o webui option , how to reconfigure the ~/chef.json to
run chef on 4040 as well ?

I tried to edit the one in this way but 4040 port remains closed .

{
“chef_server”: {
“server_url”: “http://localhost:4000”,
“init_style”: “init”,
“webui_enabled”: true
},
“run_list”: [ “recipe[chef-server::rubygems-install]” ]

}

I understand I need to use the [chef::bootstrap_server ] recipe . How and
where this should be done?
