    /sbin/chkconfig --levels 235 mysqld on
  2. Start the MySQL:
    service mysqld start
    MySQL will bind to localhost (127.0.0.1) by default
  3. Harden MySQL Server
    Run the mysql_secure_installation script to address several security concerns in a default MySQL installation

Mysql Root Login:

then type your root password

Create new user and database

create new database with name newDB, new user with name newUser and newPassword is newUser‘s password:
create database newDB;
create user 'newUser'@'localhost' identified by 'newPassword';
grant all on newDB.* to 'newUser' identified by 'newPassword';

and exit root mysql to login as newUser:

mysql -u newUser -p

and type newUser’s password and if it show mysql>, you have succeed

Reset the MySQL Root Password

If you forget your root MySQL password, it can be flushed and then reset.

  1. Stop the current MySQL server instance, then restart it with an option to not ask for a password.

    sudo /etc/init.d/mysqld stop
    sudo mysqld_safe --skip-grant-tables &
  2. Reconnect to the MySQL server with the MySQL root account.
    mysql -u root
  3. Use the following commands to reset root’s password. Replace password with a strong password.

    use mysql;
    update user SET PASSWORD=PASSWORD("password") WHERE USER='root';
    flush privileges;
    exit
  4. Then restart MySQL.

    service mysqld restart

You’ll now be able to log in again using mysql -u root -p.

Dump and restore backup

$ mysqldump –opt -u [uname] -p[pass] [dbname] > [backupfile.sql]

$ mysql -u [uname] -p[pass] [db_to_restore] < [backupfile.sql]
