Error connecting to database

Dianna Newman

I am reinstalling Jira to our new Linux server and I got this error:

Error connecting to database

Cannot load connection class because of underlying exception: com.mysql.cj.core.exceptions.WrongArgumentException: Malformed database URL, failed to parse the connection string near '=InnoDB'.

Originally it said that the mysql connector file was missing so I put 'mysql-connector-java-6.0.6.jar' into the lib folder as directed. Now I have a new error that I just don't know how to fix. I have set up a brand new database.

You've given the setup an incorrect or badly formed url when ytying to connect. We need to see that.

Depending on how far through the install you've got, there are two possibilities.

1. There's a file in your JIRA home directory called dbconfig.xml which has the connection settings in it. We just need to see the connection string out of that, not username and password etc.

2. What are you entering when the system asks you for the database connection details

Dianna Newman

I don't see any dbconfig.xml file under Jira. I see a lock file.

Here is a photo from my screen

Ok, it's not been able to connect, so it has not created the dbconfig file. I sort of expected that, but had to check.

The parameters you are entering look good to me, so I'm not sure what is wrong.

Next thing to do is a look at the log file, which should tell us the full reason for the failure and contain the string it has constructed to try the connection. Should be under "logs" in the directory you found the lock file.

I had the same problem.

In my case I was using the wrong driver version.

I used version 6.0.6, but the correct version is 5.1.44

Take a look at the documentation about Copy the MySQL JDBC driver to your application server

The documentation says

If you are installing JIRA, download the recommended MySQL driver JDBC Connector/J 5.1. You can download either the .tar.gz or the .zip file by selecting the 'Platform Independent' option. Extract the jar for the driver (e.g. mysql-connector-java-5.x.x-bin.jar) from the archive.

I downloaded the driver from the central maven repository: mysql » mysql-connector-java

using

wget http://central.maven.org/maven2/mysql/mysql-connector-java/5.1.44/mysql-connector-java-5.1.44.jar

Thanks! I got same error and the old mysql-connector-java-5.1.46.jar fixed it.

I'm setting up Jira on Ubuntu 16.04, MySQL 5.7 all dancing on VMware.

I'm thinking the documentation isn't clearly stating, "please use the old drivers". I ran into the same scenario setting up Conflunence, it wanted an old driver.

Thanks again for this post.
