To Modify the root password:

Copy Code code as follows:

mysqladmin-u root Password "YourPassword"

Configuration:

Attention, in Ubuntu under MySQL default is only allowed local access, if you want other machines can also access, then need to change the/ETC/MYSQL/MY.CNF configuration file! Here's a step-by-step:
The default MySQL installation after the root user does not have a password, so first access to the root user:
$mysql-U root-p
The reason for using-u root is that I am now a general user (Firehare), and if you do not add-u root, MySQL will assume that Firehare is logged in. Note that I did not enter root user mode here because it is not necessary. In general, the database in MySQL operation, there is no need to enter root user mode, only when the possibility of setting.
After entering MySQL, the most important thing is to set the root user password in MySQL, otherwise, the MySQL service is not safe to say.
mysql> GRANT all privileges on *.* to root@localhost identified by "123456";
Note that I'm using 123456 as the root password, but the password is unsafe, please use the combination of uppercase and lowercase letters and numbers, and not less than 8 digits.
In this way, you set the root password in MySQL, and then use the root to create the database you need. Here I take xoops as an example:
mysql>create DATABASE xoops;
Mysql>grant all privileges in xoops.* to Xoops_root@localhost identified by "654321";
This creates a xoops_roots user that has full permissions to the database Xoops. Later, the Xoops database is managed with xoops_root, without the need to use the root user, and the user's permissions are limited to the Xoops database.
If you want to make remote access or control, then you have to do two things:
One :
Mysql>grant all privileges in xoops.* to xoops_root@ "%" identified by "654321";
Allows xoops_root users to log on to MySQL from any machine.
secondly:
$sudo gedit/etc/mysql/my.cnf
>skip-networking => # skip-networking
This allows other machines to access MySQL.
