Question

When I installed mysql it came with two database, mysql and information schema. I accidentally deleted the mysql database. Is there any way I can recreate it?

Also, since it contains a table that contains user information, would there be any way I can view users’ information without it?

Answer 1

If you are still able to log in (I assume you aren’t since there’s no user table) and have databases to save, dump them with

mysqldump --routines databasename > outfile.sql

The MySQL database can be recreated with the command

# Most MySQL versions
mysql_install_db

# MySQL 5.7 and later
mysqld --initialize
