How to install and configure Mysql after oracle acquires Mysql

Since oracle's acquisition of Mysql, there have been some minor changes. After mysql was installed, there is no password by default, however, after the new version of mysql is installed, oracle provides a free password with/root /. in the mysql_secret file, the installation process on redhat6.2 is described in detail below.

Download the package of the operating system at http://www.mysql.com/downloads/

The following is a comprehensive installation document on the Internet. mysql installation is quite simple. I personally recommend using the rpm package installation method.

Mysql downloaded on the oracle official website now has the following rpm packages

MySQL-client-advanced

MySQL-devel-advanced

MySQL-embedded-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-server-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-shared-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-shared-compat-advanced-5.6.14-1.rhel5.x86_64.rpm

MySQL-test-advanced-5.6.14-1.rhel5.x86_64.rpm

1. First, find all the mysql instances installed in the system.

# Rpm-qa | grep-I after mysql runs this command, all lists are displayed:

Mysqlclient10-3.23.58-4.RHEL4.1

Mysqlclient10-devel-3.23.58-4.RHEL4.1

2. Force Delete the list one by one:

# Rpm-ev -- nodeps mysqlclient10-3.23.58-4.RHEL4.1.

# Rpm-ev -- nodeps mysqlclient10-devel-3.23.58-4.RHEL4.1.

3. manually delete several files of earlier versions:

# Rm-f/etc/my. cnf

# Rm-rf/var/lib/mysql

# Rm-rf/var/share/mysql

# Rm-rf/usr/bin/mysql *

4. Install the downloaded mysql version,

[Root @ oracle11 ~] # Rpm-ivh MySQL-server-advanced-5.6.14-1.el6.x86_64.rpm

Preparing... ######################################## ### [100%]

1: mySQL-server-advanced ################################### ####### [1, 100%]

5. Install the client

[Root @ oracle11 ~] # Rpm-ivh MySQL-client-advanced-5.6.14-1.el6.x86_64.rpm

Preparing... ######################################## ### [100%]

1: mySQL-client-advanced ################################### ####### [1, 100%]

NOTE: If mysql-client is not installed, you cannot log on to the mysql database using the mysql tool.

6. after oracle acquires Mysql, the new version of mysql cannot directly enter mysql to log on to the database after mysql is installed. Instead, the default free password is set, and the default password is stored in/root /. in the mysql_secret file, you need to change the password after logging on

After the installation is complete,

A randompassword has been set for the MySQL root USER!

You willfind that password in '/root/. mysql_secret '.

You must change thatpassword on your first connect,

No other statementbut 'set password' will beaccepted.

See the manual forthe semantics of the 'password expired' flag.

Also, the accountfor the anonymous user has been removed.

In addition, you canrun:

/Usr/bin/mysql_secure_installation

Which will also giveyou the option of removing the test database.

This is stronglyrecommended for production servers.

See the manual formore instructions.

Please report anyproblems with the/usr/bin/mysqlbug script!

New default configfile was created as/usr/my. cnf and

Will be used bydefault by the server when you start it.

You may edit thisfile to change server settings

7. Change Password

(1) view the file and find the password

[Root @ oracle11 ~] # Vi/root/. mysql_secret

# The randompassword set for the root user at Mon Oct 28 11:09:39 2013 (local time): 3 eriwUfI

(2) log on to Mysql

[Root @ oracle11 ~] # Mysql-u root-p

Enter password:

Welcome to the MySQLmonitor. Commands end with; or \ g.

Your MySQLconnection id is 3

Mysql>

(3) change the password

Mysql> setpassword for 'root' @ 'localhost' = password ('root ');

Query OK, 0 rowsaffected (0.05 sec)

Of course, you can also use the script/usr/bin/mysql_secure_installation to interactively modify the mysql root Password, as shown below:

[Root @ oracle11 ~] #/Usr/bin/mysql_secure_installation

NOTE: running all parts of this script is 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 will be blank,
So you shoshould just press enter here.

Enter current password for root (enter for none ):
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
Them. This is intended only for testing, and to make the installation
Go a bit smoother. You shoshould remove them before moving into
Production environment.

Remove anonymous users? [Y/n] n
... Skipping.

Normally, root shoshould 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] n
... Skipping.

By default, MySQL comes with a database named 'test' that anyone can
Access. This is also intended only for testing, and shocould be removed
Before moving into a production environment.

Remove test database and access to it? [Y/n] n
... Skipping.

Reloading the privilege tables will ensure that all changes made so far
Will take effect immediately.

Reload privilege tables now? [Y/n] n
... Skipping.

All done! If you 've completed all of the above steps, your MySQL
Installation shoshould now be secure.

Thanks for using MySQL!
