The jobqueue keeps blocking as I'm putting my multi-server cluster together. I've tried the htf-common-issues script and it reports nothing untoward. I've tried running the server.sh script manually - with loglevel "debug" - and that's revealing nothing. But then I tried "mysql -u ispcsrv2 -h node1.domain.tld" from node0 - I looked in the database with phpmyadmin to see that the user is "ispcsrv2" and that there is no password (field is blank). And I'm getting an "access denied". Generally, MySQL / MariaDB as installed on Ubuntu 16.04 has been a pain because it locks down everything by default. As the multi-server install instructions suggest, I created "root" users for every IP address and hostname. I cleared the "plugin" that's installed that prevents remote logins. I also created a 'root'@'%' user so that you ought to be able to login as root from anywhere (with the correct password). I can see, with phpMyAdmin, that the master server (node0) has created the "ispcsrv2" and "ispconfig" users. Node1 has an "ispconfig" user. And, yes, I gave it over 15 minutes waiting for the job to disappear. It was definitely blocked. Indeed, I tried uninstalling and reinstalling (including manually clearing out the user entries with phpMyAdmin too) and it still happens. I think what's happening is that the master server is getting an "access denied" to the other node, like I am when I try to login in manually from the command line, and this means the job blocks forever as it can never be completed. Edit - Yes, when I run "uninstall.php" to try it again, then it says "access denied" with logging in as "ispcsrv2@node0" from node1. And the node doesn't disappear on node0's interface. So it's basically not getting through to the master server to let it know it's uninstalling.
