Description C.J.S. Hayward 2017-06-23 23:35:42 UTC
As of 17.05.01, I was told there were reports of successful installations. However, I have not been able to reproduce such.

I had earlier made a couple of attempts to add Koha to a multipurpose appliance, and that remains my end goal. However, when I tried to back up, I saw the same issue verbatim.

What I have done today was:

Download a fresh Linux Mint 18.1 ISO.

Build a VirtualBox VM with the ISO, with mostly default features and with third-party addons, and also enabling auto-login, but in general intended to be a plain vanilla install.

Rebooted; installed Chrome and touched /etc/sudoers, ran "aptitude update"; ran "aptitude upgrade", installed MariaDB, and rebooted again.

Followed the steps, including a couple of a2enmod enablings, and created a virtual site.

I was able to edit passwords in /etc/koha/.../koha-conf.xml, and enter the web setup wizard.

However, I experienced identical output from the installer: at a certain point, it says:

> Software error:
> 
> DBIx::Class::Storage::DBI::catch {...} (): DBI Connection failed: Access denied for user 'root'@'localhost' at /usr/share/perl5/DBIx/Class/Storage/DBI.pm line 1492. at /usr/share/koha/lib/Koha/Database.pm line 100
For help, please send mail to the webmaster ([no address given]), giving this error message and the time and date of the error.

I am having difficulties with MariaDB and my difficulties may be contributing to the problem.

My understanding, as inherited from MySQL, is that "mysql -uroot -p", for any account that will run it, will check a password and, if you have root's password set, will let you into the MySQL root command line if and only if you type the password exactly.

The behavior I have observed is that as root "mysql -uroot" does not prompt for a password, but just logs you in, and "mysql -uroot -p" prompts for a password, but will accept any password, the empty password included. However, from an unprivileged account, "mysql -uroot -p" prompts for a password, but none of the passwords I've tried have worked; I've tried and used values as set in my customized koha-conf.xml, and every single password is rejected.

I believe that this command line behavior is a symptom of the same problem quoted above: permission is being denied for user 'root'@'localhost' where the action in question would be permitted for any account with UID 0 and no account with any other UID.

Again, this is after the 17.05.01 release, where it was reported to me that some people have had success. The system setup shows a couple of my personal idiosyncracies, but is meant to be awfully close to a procedure of "Step 1: Create a new Linux Mint VM. Step 2: Install Koha." The behavior is the same between the fresh new VM running 17.05.01, and an "everything but the kitchen sink" multitool of an appliance.

Please bring this up on the mailing list - many more people are reading there. There is probably only a handful reading the incoming bug reports.

Hi,

This sounds like it is because of an odd "feature" of mysql which is not always present.

This page: https://askubuntu.com/questions/766334/cant-login-as-mysql-user-root-from-normal-user-account-in-ubuntu-16-04

with the answer from "Todor", explains that mysql will change over to using an auth_socket "plugin."  So, instead of using password authentication, part of the permission is blocked by unix file-level permissions.

The simple solution:

   sudo mysql -u root
   update mysql.user set plugin = 'mysql_native_password' where User='root';
   FLUSH PRIVILEGES;

Then you should be able to connect up as root even if you are not a root user.

After that, you should be able to run the script.
