Describes a very useful mysql boot parameter ——--Skip-grant-tables. As the name implies, when you start MySQL, do not start the grant-tables, authorization table. What's the use of it? Of course it is useful to forget the administrator password.
Operation Method:
1. Kill the original MySQL:
Rcmysqld stop
Service Mysqld Stop
Kill-term mysqld
2. Start MySQL with command line parameters:
/usr/bin/mysqld_safe--skip-grant-tables &
3. Modify the Administrator password:
Use MySQL;
Update user set Password=password (' Yournewpasswordhere ') where user= ' root ';
Flush privileges;
4. Kill MySQL and restart MySQL
