Failed to create the EUM user account in the database.

When I run the script to install EUM (euem-64bit-linux-21.4.3.34447.sh), it showed this notification:

 

....

Setting the configuration properties...
Checking EUM MySQL version
Please wait as this operation may take some time...
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
Failed to create the EUM user account in the database.

Rolling back changes ...

Please help me to fix this. Can we create account manually?

I still stuck in this problem. I test to install new server run Redhat 7.9 in my lab same as in my product. I had the same error.

Anyone here get this error?

Hi @Tuan.Le,

 

Can you confirm if the requirements given in the below doc were followed before you have tried the installation and if not, request you to install the packages.
 
https://docs.appdynamics.com/21.4/en/application-performance-monitoring-platform/eum-server-deployme...
 

The EUM processor requires the libaio library to be on the system. This library facilitates asynchronous I/O operations on the system. Note if you have a NUMA based architecture, then you are required to install the numactl package.

 
Install these packages if not done already and then before retrying the install again, You would need to delete the old failed installation directory and then try it out

Hi @ryan

 

My server has 8 core, 100GB RAM, 500GB Harddisk.

For POV purposes, so now I'm installing Controller (version 21.4) and EUM in the same server. (On-premise)

I follow this link the Platform Installation :: AppDynamics PoV Playbook (appdpartnerlabs.net)

My first installation in my lab, I choose type Demo. It's OK. But when I choose type Product, I get this error.

I still try to uninstall, delete all directories of EUM and reinstall again but it did not work.

Hi @Tuan.Le,

 

Not sure if you have already done this, but I would recommend contacting our Sales team to see if they can help you out getting things all set up.
