How do I connect to my MySQL service on Pivotal Cloud Foundry (PCF) via MySQL Workbench or CLI or MySQLWeb Database Management App?

问题

I have a Spring Boot based REST application that is deployed on Pivotal Cloud Foundry (PCF) and working fine. But this REST application did not had any DB connection till now. Hence, I decided to install MySQL service on PCF from the marketplace and finally got it bounded to my application successfully.

However, the problem is that I am NOT able to connect to this newly created MySQL instance via CLI or any other GUI.

So far I have followed following links but no luck.

https://docs.pivotal.io/pivotalcf/2-4/devguide/deploy-apps/ssh-services.html
How to setup mysql develper for PCF mySQL database to manage it

The steps that I performed in order to accomplish this are:

Created service instance for MySQL successfully
Bound the service instance for MySQL to the application successfully (see the cf services command result above)

# cf services

name service plan bound apps last operation
```
my-mysql-db             cleardb          spark      agrisell-rest-app   create succeeded
```
Pushed my app successfully and can hit the REST API successfully

https://agrisell-rest-app.cfapps.io/hello
Enabled ssh on the host app using cf enable-ssh agrisell-rest-app successfully
Created service key using cf create-service-key my-mysql-db my-mysql-db-service-key (the command for fetching service keys after creation is shown below)

# cf service-keys my-mysql-db

name my-mysql-db-service-key
Retrieved service key and DB credentials using following command

cf service-key my-mysql-db my-mysql-db-service-key

{
 "hostname": "us-cdbr-iron-east-01.cleardb.net",
 "jdbcUrl": "jdbc:mysql://us-cdbr-iron-east-01.cleardb.net/ad_b509d7f388732d5?user=hello123\u0026password=world456",
 "name": "ad_b509d7f388732d5",
 "password": "world456",
 "port": "3306",
 "uri": "mysql://b311794a3c31eb:ca7ad71f@us-cdbr-iron-east-01.cleardb.net:3306/ad_b509d7f388732d5?reconnect=true",
 "username": "hello123"
}

Configured SSH tunnel successfully

cf ssh -L 63306:us-cdbr-iron-east-01.cleardb.net:3306 agrisell-rest-app
Accessing the service instance through CLI

vcap@33eb3942-10bd-4068-650f-64fc:~$ mysql -u hello123 -h 0 -p -D ad_b509d7f388732d5 -P 63306 bash: mysql: command not found

Based the above error it felt to me as if did not install the mysql plugins correctly but I already have them installed.

# cf plugins
Listing installed plugins...

plugin   version   command name   command help
mysql    2.0.0     mysql          Connect to a MySQL database service
mysql    2.0.0     mysqldump      Dump a MySQL database

Use 'cf repo-plugins' to list plugins in registered repos available to install.

Second Approach:

Second approach I tried was to connect to the PCF MySQL DB through MySQL Workbench which comes bundled with MySQL server installation on Windows. I use it to connect to my local MySQL DB. I modified the settings to point it to the host, db and changed credentials and tried to connect which did not work either.

Third Approach

Third approach that I tried was installing Pivotal MySQL Web Database Management tool which I from one of the PCF documentation

https://docs.pivotal.io/p-mysql/2-2/use.html#mysqlweb

I installed it on my Windows 10 machine (did not deploy it to PCF) and tried to log in but that also failed.

Second Approach Tried and Failed

Based on your response Arun, I followed all the instructions mentioned in the Readme here (https://github.com/pivotal-cf/PivotalMySQLWeb) but it does not allow me to login to the application with DB URL and credentials. The first login with credentials admin/cfmysqlweb works but the login page where it requires DB credentials and password it send me back to the first login screen with a message "Bad Credentials". Screenshot below.

Deployed the PivotalMysqlWeb on PCF and bound it to DB instance

Login Page that shows up now after basic authentication is successful using admin/cfmysqlweb credentials

DB credentials entered above and on submit I am taken back to the first login page (Back to square one)

You cannot connect with any of the Marketplace service with the tools that you have in your PC / Laptop (like what you do with MySQL App)

The reason is that any Marketplace service within PCF can be running anywhere and you are just provided an instance of it .

For security purpose, your Marketplace service (that you ordered .. that you paid) is just exposed only to that particular PCF Foundation ..

If you still want to connect to MySQL and have a look at your database, I recommend you to use PivotalMySQLWeb tool . You would have to upload this App in the same PCF-space and bind it to your MySQL DB Instance that you would have created in that space. You can view lot of instructions in their README file

I installed MySQL Workbench and created a new connection. Then filled in the details from the service details on PCF (the ones you posted)

{
 "hostname": "us-cdbr-iron-east-01.cleardb.net",
 "jdbcUrl": "jdbc:mysql://us-cdbr-iron-east-01.cleardb.net/ad_b509d7f388732d5?user=hello123\u0026password=world456",
 "name": "ad_b509d7f388732d5",
 "password": "world456",
 "port": "3306",
 "uri": "mysql://b311794a3c31eb:ca7ad71f@us-cdbr-iron-east-01.cleardb.net:3306/ad_b509d7f388732d5?reconnect=true",
 "username": "hello123"
}

So in your case:

host: us-cdbr-iron-east-01.cleardb.net

Username: hello123

Password: world456

default Schema: ad_b509d7f388732d5 Port: 3306

Interesting to note, the default schema need to match the "name" attribute. I put a custom name and couldn't connect. Not super sure why, but what can you do.

In case anyone wants to connect aws-rds-mysql (instantiated from Pivotal Cloud Foundry) from IntelliJ, here are the steps:

Once you have created ssh tunnel, you can access the AWS-RDS database from your localhost on port 63306, follow the instructions in order to connect DB with DB Navigator plugin (intelliJ )

Install DB Navigator plugin in intelliJ (Community Edition), if you have't installed already -> https://plugins.jetbrains.com/plugin/1800-database-navigator
Connect to AWS RDS in intelliJ -> notice the connection is made via localhost on port 63306
- Go to DB Navigator plugin and click on custom under new connection.
- Enter the URL as: jdbc:mysql://:@localhost:63306/<database_name>

Steps are also available at GitHub
