The following error occured due to magento setup:upgrade
As a result the mysql connection keeps dropping for every request (if i refresh page.navigate to other page)
I am all new to Iava and JDBC. Probably making a simple mistake. I am trying to start MySQL from NetBeans with the following server properties:

I realise I probably have to add some connector but I don't know where and how.
I am trying to setup MariaDB on my local machine.
Whenever I try to log in with:
mariadb -u <mac_name> or mariadb -u root I get this error:
using my mac password also doesn't work.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
When I tail the logs found at /usr/local/var/mysql/<host_name>.err or /usr/local/var/mysql/<host_name>.local.err
I get these errors:
[Note] InnoDB: Completed initialization of buffer pool
[ERROR] InnoDB: Invalid flags 0x4800 in ./ibdata1

Does anyone know how I could get this working?
This one is stumping me bigtime...

I am using a hosting server that doesn't provide me with a root account.
They don't provide me with an installation service of database.
The server is Red Hat Enterprise Linux Server release 6.1 (Santiago) x86_64.
I tried to download and install MySQL 5.7.10, but it shows me errors regarding to InnoDB setup as below:
[hoge#blackett mysql]$ ./bin/mysqld --initialize --basedir=/home/hoge/mysql --character-set-server=utf8

I also did the following:
cp ./support-files/my-default.cnf ~/my.cnf
I tried the following command, but it gives me the same errors:
[hoge#blackett mysql]$ ./bin/mysqld --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql --defaults-file=/home/hoge/my.cnf
I wrote the following in my.cnf, but doesn't solve the error:
innodb_use_native_aio = 0
I have no ideas to solve them.
Could you please help me?
Maybe...
On Linux systems, running multiple MySQL servers (typically more than
12) with default settings for innodb_read_io_threads,
innodb_write_io_threads, and the Linux aio-max-nr setting can exceed
system limits. Ideally, increase the aio-max-nr setting; as a
workaround, you might reduce the settings for one or both of the
MySQL configuration options.

I resolved the issue myself.
The document https://dev.mysql.com/doc/refman/5.7/en/data-directory-initialization-mysqld.html says
the --defaults-file option must be first
When I typed ./bin/mysqld --defaults-file=/home/hoge/my.cnf --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql, the option file was recognized.
Another solution is to specify --innodb_use_native_aio=0 option directly without using the option file, my.cnf, as below:
./bin/mysqld --initialize --basedir=/home/utpsy/mysql --character-set-server=utf8 --innodb_use_native_aio=0
