I'm using OS X (Yosemite) and this error happened to me when I upgraded from Mavericks to Yosemite. It was solved by using this command
sudo /usr/local/mysql/support-files/mysql.server start
回答2:
The MySQL daemon should not be executed as the system user root which (normally) do not has any restrictions.
According to your cli, I suppose you wanted to execute the initscript instead:
sudo /etc/init.d/mysql stop
Another way would be to use the mysqladmin tool (note, root is the MySQL root user here, not the system root user):
/usr/local/mysql/bin/mysqladmin --port=8889 -u root shutdown

Try this for Amazon Linux AMI or for centOS
sudo service mysqld restart
回答4:
osx could be using launchctl to launch mysql. Try this:
sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysqld.plist

Donal had the right solution for me. However, the updated plist name for 2017 is
com.oracle.oss.mysql.mysqld.plist.

On top of @mise's answer, After I installed MacOS Mojave, I also had to change files ownership on all my MAMP directory and contents).
From the Finder, I went in Application/MAMP, showed files info (cmd + i) and in permissions section added myself with read & write perms, then from the little gear applied to all the children.

The correct answer that worked for me on CentOS is
/etc/init.d/mysql restart
which is an init script and not /etc/init.d/mysqld restart, which is binary
The is in fact comment of @MrTux on the question which worked for me. It took quite a bit of my time hence posting it as answer.

How i resolved this was following the 4th point in this url: https://dev.mysql.com/doc/refman/8.0/en/changing-mysql-user.html
- Edit my.cnf
- Add
user = rootunder under [mysqld] group of the file
If this doesn't work then make sure you have changed the password from default.
回答9:
to run mysqld as root user from command line you need to add the switch/options --user=root
mariadb run as system root user
回答10:
in my case (RHEL7 and MariaDB) this works.
sudo systemctl restart mariadb
