Mysql Installation Summary In F7

It took me a lot of effort to run mysql in these two systems

To sum up

After running mysqld_safe, check the logs in/var/log/mysql. log.

If there is no specific error information in the log

You can modify the log records in the my. cnf file and add the # sign before log_err =... Or log_bin = ....

Run the command and check the log file carefully.

In mysql that is not installed according to the system, check whether there is a mysql account. If this account is not added

Useradd mysql

For other errors, you must first modify the mysql installation path and database permissions, and set the maximum permission to 0666.

If you have defined the my. cnf file, and the configuration of my. cnf file is ignored in the log, you need to change the attribute of the my. cnf file to 0644.

This is mainly about permissions.
