Public bug reported: The mysqld.cnf file includes a commented out line for log_slow_queries = /var/log/mysql/mysql-slow.log
As it turns out, log_slow_queries was deprecated long ago and it now causes MySQL 5.7 to fail to start/restart if it exists. The current variable/option is slow_query_log_file. By including this deprecated variable/option, users are going to get failures to restart that are not even printed to the MySQL log file. I did not find ANY log of what happened, only that MySQL failed to start. I believe this justifies updating mysqld.cnf with the current option so other users don't go through the frustration that I just experienced. For me, this is running on a clean install of Ubuntu 16.04 LTS with the default xenial package install for mysql (which is 5.7). I installed it via "apt-get install". ** Affects: mysql-5.7 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577096 Title: MySQL 5.7 on Xenial ships w/mysqld.cnf that causes crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1577096/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
