Access denied for root@localhost

@Hanz I cannot see how this is related to the topic of Ubuntu 16.04 mysql issues!?! Please help me.

[Quazz]

@Sebastian-Roth Unable to create tasks, no fog settings being displayed, the php error spam.

Mysql seems to work fine now (assuming it’s not causing the other issues that is)

[Quazz]

Images are unable to deploy (input/output error).

The other php errors have no longer showed up since Tom’s tomfoolery

you should dump Ubuntu for this:
https://www.turnkeylinux.org/lampstack

install is SO easy and the features of the stack are good too.

Added subnet to evasive mod whitelist to get rid off a bunch of stupid errors (it kept on blocking getfiles.php)

Perhaps worth noting that both php7.0-mbstring and php-mbstring exist and are in fact different packages. (why…)

[Sebastian Roth]

I think we need to face 16.04 at some point to I am trying to get a wiki article together: https://wiki.fogproject.org/wiki/index.php?title=Ubuntu_16.04

[NSmith]

I found the solution for me in this article: https://www.percona.com/blog/2016/03/16/change-user-password-in-mysql-5-7-with-plugin-auth_socket/

basically comes down to the following as the fix :

sudo mysql -u root
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’;
exit

[Wayne Workman]

@NSmith that’s in our wiki. https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_MySQL#MySQL_credentials_for_FOG_Main_and_Storage_Nodes

[Sebastian Roth]

@Wayne-Workman Sorry, but that’s a bit of a different story as Ubuntu 16.04 comes with MySQL 5.7 which defaults to something called auth_socket in contrast to normal tcp localhost socket connection.

Issue and solution are known and documented here and here.

[Wayne Workman]

@Sebastian-Roth Is there any way to address this in the installer so that it works out of the box for Ubuntu 16?

[Sebastian Roth]

@Wayne-Workman Yes, force people to set a MySQL root password when installing. But it would still fail if people have MySQL server pre-installed (with empty password)… Other than that I don’t think we have any chance to hook into the auth_socket thing. See if you can find anything related to php and auth_socket
