  7. Start MySQL server: [root@mcctb ~]# service mysqld start
    Initializing MySQL database:  2016-04-05 19:44:38 0 [Warning] TIMESTAMP with implicit DEFAULT 
    value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation
     for more details).
    2016-04-05 19:44:38 0 [Note] /usr/sbin/mysqld (mysqld 5.6.29) starting as process 2487 ...

    2016-04-05 19:44:42 2509 [Note] InnoDB: Shutdown completed; log sequence number 1625987
    To do so, start the server, then issue the following commands:
      /usr/bin/mysqladmin -u root password 'new-password'
      /usr/bin/mysqladmin -u root -h mcctb password 'new-password'
    Alternatively, you can run:
    which will also give you the option of removing the test
    databases and anonymous user created by default.  This is
    strongly recommended for production servers.
    ....Output truncated....
    WARNING: Default config file /etc/my.cnf exists on the system
    This file will be read by default by the MySQL server
    If you do not want to use this, either remove it, or use the
    --defaults-file argument to mysqld_safe when starting the server
                                                               [  OK  ]
    Starting mysqld:                                           [  OK  ]
  8. Confirm that MySQL server is running: [root@mcctb ~]# service mysqld status
    mysqld (pid  2739) is running...
  9. Configure security and password settings: [root@mcctb ~]# mysql_secure_installation
     In order to log into MySQL to secure it, we'll need the current
     password for the root user.  If you've just installed MySQL, and
     you haven't set the root password yet, the password will be blank,
     so you should just press enter here.
     Enter current password for root (enter for none):   <== on default install hit enter here
     OK, successfully used password, moving on...
     Setting the root password ensures that nobody can log into the MySQL
     root user without the proper authorisation.
     Set root password? [Y/n] y
     New password:
     Re-enter new password:
     Password updated successfully!
     Reloading privilege tables..
      ... Success!
     By default, a MySQL installation has an anonymous user, allowing anyone
     to log into MySQL without having to have a user account created for
     them.  This is intended only for testing, and to make the installation
     go a bit smoother.  You should remove them before moving into a
     production environment.
     Remove anonymous users? [Y/n] y
      ... Success!
     Normally, root should only be allowed to connect from 'localhost'.  This
     ensures that someone cannot guess at the root password from the network.
     Disallow root login remotely? [Y/n] y
      ... Success!
     By default, MySQL comes with a database named 'test' that anyone can
     access.  This is also intended only for testing, and should be removed
     before moving into a production environment.
     Remove test database and access to it? [Y/n] y
      - Dropping test database...
     ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
      ... Failed!  Not critical, keep moving...
      - Removing privileges on test database...
      ... Success!
     Reloading the privilege tables will ensure that all changes made so far
     will take effect immediately.
     Reload privilege tables now? [Y/n] y
      ... Success!
     All done!  If you've completed all of the above steps, your MySQL
     installation should now be secure.
     Thanks for using MySQL!
     Cleaning up...
