Could not create connection to database server. (MySQL)

kellyh · November 27, 2018, 2:03pm

I’m trying to setup a new instance of HippoCMS with a MySQL database.

I’m getting the following error when attempting to run mvn -Pcargo.run;

[WARNING] [talledLocalContainer] 27-Nov-2018 12:38:39.409 WARNING [localhost-startStop-1] org.apache.catalina.core.NamingContextListener.addResource Failed to register in JMX: [javax.naming.NamingException: Unexpected exception resolving reference [Root exception is java.sql.SQLException: Cannot create PoolableConnectionFactory (Could not create connection to database server.)]]

Using Configure Hippo CMS for MySQL as a guide I’ve done the following;

Added the example JNDI resource to conf/context.xml after replacing DBUSER, DBPASS, DBHOST, DBPORT and DBNAME
Added the example repository.xml file to the conf directory
Created a database on a local instance of MySQL
Created a user with CREATE, ALTER, DROP, INDEX, SELECT, INSERT, UPDATE, DELETE and LOCK TABLES privileges

This is also for a development environment so using Use MySQL in a Development Environment I have;

Added the MySQL driver dependency to pom.xml. (I added the <dependencies> node alongside the <depenendencyManagement> node instead of inside it as mentioned in the warning in the instructions.)
Added the MySQL driver to the cargo.run profile in pom.xml
Added the repo.config to the <systemProperties> in the cargo.run profile

I’ve checked every page in the documentation that seems relevant but I’m not sure where I’m going wrong.

I’m happy to provide more specific information about any of the above but didn’t know which finer details would be important and which would just be clutter.

Thanks in advance.

Well the error is that is can’t connect to the database. Check to see that the database is running and accessible.

@jasper.floor Thanks for the reply

The database is running and accessible. I confirmed this by connecting to it via another application on a different machine.

Hope this helps

Thanks for the reply @bcanvural

Your cargo.run profile and Resource declaration match my own. So, it’s still not connected, but at least I know I’ve not done anything wrong in either of those areas, thanks

pankaj467 · February 2, 2021, 12:25pm

@bcanvural : I have created the conf/context.xml and cargo.run profile as you mention . But table is not created in MySQL database. I am not getting any error.

conf/context.xml:

<Resource

maxTotal="100" maxIdle="10" initialSize="2" maxWaitMillis="10000"

timeBetweenEvictionRunsMillis="10000"
minEvictableIdleTimeMillis="60000"
username="root" password="12345"
driverClassName="com.mysql.cj.jdbc.Driver"

2 YEARS LATER…

delete any existing storage directories (repo.path)…are you running right maven profile?

pankaj467 · February 2, 2021, 3:00pm

Thanks @machak for quick response.

I am pretty new in Bloomreach and start exploring Bloomreach couple of days before. I have face the same issue that’s why I have replied here and not create a new thread. .

I am pretty new in Bloomreach. So could you please elaborate your answer. So that I can understand and follow the steps.
