Migrate From Parse To Rackspace

Suggest Edits

This article provides instructions for migrating your Parse database to
Rackspace. It assumes that you have already migrated your database from Parse
to ObjectRocket. If you have not, you can find more information
on the ObjectRocket website.

Deploy the Parse stack

Log in to the Cloud Control Panel.
In the top navigation bar, click Select a Product > Rackspace Cloud.
Select Orchestration > Stack Templates.
In the All Stacks list, scroll to Parse and click Create Stack.
In the pop-up box, choose the flavor and then click Create Stack.
On the Create Stack page, enter a name and region for the stack, and enter your Parse site domain and email address.
(Optional) To automatically pull in and install your custom code on the new server, enter GitHub repository information.
Click Create Stack.

On the stack details page, a green Up status in the Status field indicates when the stack is active.

Configure the new server

After the stack has been successfully created, configure your database
authentication information. Repeat this procedure on all Parse servers created
in the stack. These servers are linked from the stack details page, which is
displayed after you create the stack. The parse password should be the same for
all servers.

Log in to the new primary server via SSH either as root by using the SSH key provided or as parse by using the password provided.

For more information about logging in to a server, see Connect to a cloud server.

Edit the /home/parse/parse.json configuration file to add the following values:

MongoDB Connection String
Application ID
Master Key

You can find the MongoDB Connection String value in the ObjectRocket Control Panel, listed as Connect under the instance that you plan to use. The Application ID and Master Key values are in your Parse.com account under App Settings > Security and Keys. Any other application-specific keys are optional. Leave them blank if you aren’t going to use them.

Following is an example parse.json config file:

  {
        "apps" : [{
     "name"        : "parse-wrapper",
     "script"      : "/usr/local/bin/parse-server",
     "watch"       : true,
     "merge_logs"  : true,
      "cwd"         : "/home/parse",
     "env": {
       "PARSE_SERVER_CLOUD_CODE_MAIN": "/home/parse/cloud/main.js",
       "PARSE_SERVER_DATABASE_URI": "mongodb://user:password@ip:27017/db",
       "PARSE_SERVER_APPLICATION_ID": "your_application_id",
       "PARSE_SERVER_MASTER_KEY": "your_master_key",
       "PARSE_SERVER_COLLECTION_PREFIX": "collection_prefix",
       "PARSE_SERVER_CLIENT_KEY": "your_client_key",
       "PARSE_SERVER_REST_API_KEY": "your_rest_key",
       "PARSE_SERVER_DOTNET_KEY": "your_dotnet_key",
       "PARSE_SERVER_JAVASCRIPT_KEY": "your_javascript_key",
       "PARSE_SERVER_FILE_KEY": "your_file_key",
       "PARSE_SERVER_FACEBOOK_APP_IDS": "app1, app2, app3",
       "PARSE_MOUNT": "/1",
       }
    }]
  }

Restart Parse by running the following, commands while logged in as the parse user:
```
pm2 stop 'Your Application'
pm2 start parse.json
```

You might need to modify custom code for it to run successfully. You can
find more information about this process on the Parse website.
The Parse stack already has all of the Cloud Code replacements installed.

For debugging purposes, you can view the Parse logs at /home/parse/.pm2/logs/.

Install and configure your certificate

After Parse is running, you can configure a valid certificate within NGINX. If
you do not have a valid certificate, you can purchase one through Rackspace if
you are hosting a physical server with us. If you have questions, contact your
Account Manager or Rackspace Support.

Modify /etc/nginx/conf.d/<your_url>.conf, where <your_url> is the URL that you provided when you deployed your Parse stack.

If you need help installing your SSL certificate, see NGINX's information on SSL certificate chains.
Validate your SSL certificate by using the following command:

nginx -t -c /etc/nginx/nginx.conf

Configure the Parse dashboard

The Parse stack also comes with a Parse dashboard, which enables you to visualize
all the Parse applications running on your server. The dashboard is configured
separately from the server.

Edit the /home/parse/parse-dashboard-config.json configuration file and add the Application ID and Master Key values.

Following is an example parse-dashboard-config.json file:

{
 "apps": [
     {
       "serverURL": "https://your_api_url/parse",
       "appId": "your_application_id",
       "masterKey": "your_master_key",
       "appName": "Your Application"
     }
   ]
}

Restart the Parse dashboard service by running the following command (as root):

service parse-dashboard restart
