A RANDOM PASSWORD have BEEN SET for the MySQL root USER!

You'll find that password in '/root/.mysql_secret '.

You must change this password on your first connect,

No other statement but ' SET PASSWORD ' would be accepted.

See the Manual for the semantics of the ' password expired ' flag.

Also, the anonymous user has been removed.

In addition, you can run:

/usr/bin/mysql_secure_installation

Which would also give you the option of removing the test database.

This is the strongly recommended for production servers.

See the Manual for more instructions.

Problems at http://bugs.mysql.com/

The latest information about MySQL was available on the Web at

Http://www.mysql.com

Support for MySQL by buying support/licenses at http://shop.mysql.com

New Default Config file was created as/usr/my.cnf and

Would be used by default by the server when you start it.

You could edit this file to the Change server settings

Start MySQL:

Service MySQL Start

To view the default password:

Cat/root/.mysql_secret

# The random password set for the root user at Mon 18:31:26 (local time): Uc33bridiw2e_9us

Lr_i88lp6egm18fp

To set the root password:

Mysql-u Root

Mysql>set Password=password (' Rootfllg ');

Mysql>flush privileges;

mysql>exit;

/usr/bin/mysqladmin-u root password ' new-password '

/usr/bin/mysqladmin-u root-h wiki password ' New-password '

To test the MySQL daemon:

Cd/usr/share/mysql-test

Perl mysql-test-run.pl

Safety reinforcement:

/usr/bin/mysql_secure_installation

Note:running all PARTS of this SCRIPT are RECOMMENDED for all MySQL

SERVERS in PRODUCTION use! Please READ each STEP carefully!

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 would be blank,

So, should just press ENTER here.

Enter current password to root (enter for none): Uc33bridiw2e_9us

OK, successfully used password, moving on ...

Setting The root password ensures that nobody can log into the MySQL

Root user without the proper authorisation.

You already has a root password set so that you can safely answer ' n '.

Change the root password? [y/n] Y

New password:su********

Re-enter New password:su********

Password Updated successfully!

Reloading privilege tables.

... success!

By default, a MySQL installation have an anonymous user, allowing anyone

To log into MySQL without has to has a user account created for

them. This was intended only for testing, and 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 is allowed to connect from ' localhost '. This

Ensures that someone cannot guess at the root of password from the network.

Disallow Root login remotely? [y/n] Y (There is a bug here, the root login permissions are all removed, because the default root user can only be accessed via localhost)

... success!

By default, MySQL comes with a database named ' test ' that anyone can

Access. This was 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 ...

... success!

-Removing privileges on test database ...

... success!

Reloading the privilege tables would ensure that all changes made so far

would 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 is secure.

Thanks for using mysql!

Cleaning up ...

To move the MySQL data directory:

Service MySQL Stop

Cd/var/lib/mysql

MV mysql//data/mysql/

To modify a configuration file:

Vi/usr/my.cnf

# for advice The change settings

# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

[Mysqld]

# Remove Leading # and set to the amount of RAM for the most important data

# Cache in MySQL. Start at 70% of all RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

# Remove Leading # to turn on a very important data integrity option:logging

# Changes to the binary log between backups.

# Log_bin

# These is commonly set, remove the # and set as required.

# Basedir = ...

DataDir =/data/mysql/

# port = .....

# server_id = ...

Socket =/data/mysql/mysql.sock

# Remove Leading # To set options mainly useful for reporting servers.

# The server defaults is faster for transactions and fast selects.

# Adjust sizes as needed, experiment to find the optimal values.

# join_buffer_size = 128M

# sort_buffer_size = 2M

# read_rnd_buffer_size = 2M

Sql_mode=no_engine_substitution,strict_trans_tables

To start the MySQL service:

Service MySQL Start

Skip permission control and log in to MySQL as an administrator:

Service MySQL Stop

Mysqld_safe--user=mysql--skip-grant-tables--skip-networking &

Mysql

Mysql>

To view User rights:

Mysql-uroot-p

Mysql>select host,user from user where user= "root";

Mysql>select Host,user,password from user;

To forget the root password, restore the steps:

Service MySQL Stop
Mysqld_safe--skip-grant-tables &
Mysql-uroot
Mysql>update Mysql.user Set Password=password (' MyPassword ') whereuser= ' root ';
Mysql>flush privileges;
Mysql>quit

Service MySQL Start

Mysql–uroot–p

Allow the root user remote access when there are other privileged users who can log in to MySQL:

Mysql–u username

Mysql>update mysql.user Setpassword=password ("New_password") where user= ' root ' and host= ' localhost ';
Mysql> Grant All on * * to [e-mail protected] ' localhost ' identified by ' YourPassword ';
Mysql> Grant All on * * to [e-mail protected] '% ' identified by ' YourPassword ';

Mysql>flush privileges;

mysql>exit;

If the newly installed MySQL performs security hardening script mysql_secure_installation, it will cause the user table to be the case, and the root user cannot log on to MySQL from this machine. You can only reload MySQL with the following reload steps:

1. Uninstall MySQL Package
Rpm–qa | grep MySQL

Mysql-shared-compat-5.6.30-1.el6.x86_64

Mysql-client-5.6.30-1.el6.x86_64

Mysql-server-5.6.30-1.el6.x86_64

Mysql-shared-5.6.30-1.el6.x86_64

Mysql-devel-5.6.30-1.el6.x86_64

Rpm–e mysql-server-5.6.30-1.el6.x86_64

2. Delete related files

Rm-rf/var/lib/mysql/mysql (delete data file)

Rm-f/root/.mysql_secure (Delete the default root password file to regenerate the default password when the RPM package is installed, even if the root password has been changed)

3. Reinstall MySQL

RPM–IVH mysql-server-5.6.30-1.el6.x86_64.rpm

4. Change the root password

Service Mysqlstart

Cat/root/.mysql_secure

Mysql-uroot–p

Mysql>setpassword=password ('password');
