Hello,

Have you followed the steps to install MySQL 8.0 according to the guide for IMC? https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=a00094095en_us

Make sure you have the same config file parameters configured as listed there, and that you initialized with lower_case_table_names = 1 on first startup, among other things.

If that's the case, can you please share the my.cnf file parameters you are using, as well as any error shown by the envcheck when it is run as part of the installer?

Hello,

Thanks for this additional data. I would suggest first testing as you have proposed by reinstalling and initializing MySQL correctly.

Note the error log location is modified by the my.cnf file you are using. It is not under /var/lib/mysql anymore but instead

log-error=/var/log/mysqld.log

so checking the log file located there may provide more useful insights.

I think you may have shared the log from the old location?

Despite this line, the most updated logs are stored at /var/lib/mysql/localhost.log. This is the reason , i shared this particular file.
I come back after reinstalling  and starting up mysql.

Hello again,

Perhaps your root user password contains one of the invalid special characters for IMC? There is a table on page 8 of the installation guide that lists these characters which must not be used.

Hello,
yes i know. I used password given on user  installation guide. Further more, there is a specific issue message when you use a password with special characters. In my case, it doesn't display this message issue.
The exemple password contains a specific characters which seems permitted (the only one _ )
Do you think trying with an other password can succeed without specific characters ? I will try

Hello,

I'm just trying to think of other reasons why it might fail like that. Perhaps something else you could test is creating an identical user to 'root'@'localhost' with 'root'@'%' and granting it the same privileges, then trying the install again. I recall on some IMC versions it was trying to access this user instead, and it is definitely needed in cases of remote DB/distributed deployment.

Hello,

Have you followed the steps to install MySQL 8.0 according to the guide for IMC? https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=a00094095en_us

Make sure you have the same config file parameters configured as listed there, and that you initialized with lower_case_table_names = 1 on first startup, among other things.

If that's the case, can you please share the my.cnf file parameters you are using, as well as any error shown by the envcheck when it is run as part of the installer?
