The "Next" button is greyed out in step "Set up your database" when MySQL is selected

[Boaz Konig]

There is absolutely no indication or error output anywhere to indicate why this button is greyed out.

I have started the installation using the bin installer:  atlassian-confluence-6.12.2-x64.bin

According to your docs, this installer also installs the required JRE (but I have also tried to install Oracle JRE java version "1.8.0_191" with same results)

Operating system is headless Ubuntu server 18.10

I have installed MySQL Ver 14.14 Distrib 5.7.24, and configured it as per https://confluence.atlassian.com/doc/database-setup-for-mysql-128747.html

One Issue here which may be the source of greyed out "Next":

Your manual says to execute this command in mysql:

GRANT ALL PRIVILEGES ON <database-name>.* TO '<confluenceuser>'@'localhost' IDENTIFIED BY '<password>';

....but nowhere did your installer gave me the password it created for the confluence user it created. So how must I know what it is?, and if I change it, how will Confluence know what it is?

Anyways, I have also installed this JDBC driver "mysql-connector-java-5.1.47-bin.jar" by copying it to "/opt/atlassian/confluence/WEB-INF/lib/" and making it executable:  (NOTE that I had to create the directories /WEB-INF/lib/ as they did not exist)

sudo chown confluence:confluence mysql-connector-java-5.1.47-bin.jar
sudo chmod 755 mysql-connector-java-5.1.47-bin.jar

I have also tried making confluence a sudo user:

sudo usermod -a -G sudo confluence

I did restart the confluence server after putting the driver file there.

It is also VERY unclear from this web page:

https://confluence.atlassian.com/doc/configuring-a-datasource-connection-937166084.html

if the steps on this web page is ONLY for a JNDI connection or if the steps for Tomcat etc should also be done for a JDBC connection.

So how do I get passed this issue? 

How do I get what is bugging Confluence to keep that "Next" butt grey?

Hey,

it's not very detailed in the documentation but you create the confluence database and username yourself. The statement is actually creating a user with a password of your choice.
