回答1:

You will get detailed info in systemd journal: sudo journalctl -f then, on an other terminal, start mysql: sudo systemctl start mysqld to get logs on the first terminal. You will likely get error messages that will help you figure out what goes wrong.

回答2:

You should type this command before starting the service

mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

ِAnd later you can start the service Regularly

For one session:

systemctl start mysqld

OR being enabled automatically on startup << (NOT RECOMMENDED)

systemctl enable mysqld

Did you follow the install instruction on the ArchLinux Wiki ?

https://wiki.archlinux.org/index.php/MySQL#Installation

As mentionned by Medo Tareq, you need to run the following command :

mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

(Obviously you can adjust the parameters on the command, if you know what you are doing.)

The Wiki page also has other hint and information, notably about the mysql_secure_installation command that "will interactively guide you through a number of recomended security measures at the database level".

Try change the permission of MySQL folder. If you are working locally and try to reinstall MySQL again after runing this command, it will work.

sudo chmod -R 755 /var/lib/mysql/
