ran into this issue in a 12.04 upgrade, my conf is spread across include files based on usage.
I had this for 5.1 (note the two server settings): /etc/mysql/conf.d$ cat charset.cnf [mysqld] collation-server = utf8_unicode_ci character-set-server = utf8 default-character-set=utf8 [client] default-character-set=utf8 sudo mysql service start - this would hang until sending a Ctrl+C Changing to this allowed mysql to start, I guess the client entry is Ok. /etc/mysql/conf.d$ cat charset.cnf [mysqld] collation-server = utf8_unicode_ci character-set-server = utf8 [client] default-character-set=utf8 Bit of a tough one, It's possible mysql (the vendor) issued notices about deprecated configuration but it would be good if the service start would not hang and instead issue a warning and die with log messages so a sysadmin knows what's happening. I checked logs (syslog, mysql error log) and nothing showed up, thinking AppArmor was the issue - which has happened before - I uninstalled that to test but no cigar. Reinstalled and the same issue. If you hit this issue in a 12.04 upgrade, try out the charset conf change above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/958120 Title: MySQL does not start with utf8 options To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/958120/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
