Para crear la contraseña del usuario root de MySQL ejecutamos:
mysql_secure_installation
Debemos responder a las preguntas con las acciones resaltadas en negrilla:
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we''ll need the current
password for the root user. If you''ve just installed MariaDB, 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):'presione ENTER'
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] 'presione ENTER'
New password: 'Coloque su clave de root de la base de datos y anótela, luego ENTER'
Re-enter new password: 'Coloque de nuevo su clave de root de la base de datos, luego ENTER'
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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] 'presione ENTER'
... 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] 'presione ENTER'
... Success!
By default, MariaDB 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] 'presione ENTER'
- Dropping test database...
... Success!
- 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] 'presione ENTER'
... Success!
Cleaning up...
All done! If you''ve completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB![root@desarrolloN tmp]#
Ahora debemos configurar phpMyAdmin para que acepte conexiones adicionales a localhost, comentando la sección <Directory “/usr/share/phpmyadmin”> en:
nano /etc/httpd/conf.d/phpMyAdmin.conf
Debe quedar como:
# phpMyAdmin - Web based MySQL browser written in php
#
# Allows only localhost by default
#
# But allowing phpMyAdmin to anyone other than localhost should be considered
# dangerous unless properly secured by SSL
Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin
<Directory /usr/share/phpMyAdmin/>
<IfModule mod_authz_core.c>
# Apache 2.4
<RequireAny>
# Require ip 127.0.0.1
# Require ip ::1
Require all granted
</RequireAny>
</IfModule>
<IfModule !mod_authz_core.c>
# Apache 2.2
Order Deny,Allow
Deny from All
Allow from 127.0.0.1
Allow from ::1
</IfModule>
</Directory>
Ahora cambiamos la autenticación de phpMyAdmin de cookie a http con:
nano /etc/phpMyAdmin/config.inc.php
Debe quedar como:
[...]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'http';
[...]
Ahora se crean los enlaces de arranque del Apache y se inicia:
systemctl enable httpd.service
systemctl restart httpd.service
Ahora podemos usar un navegador para entrar por http://desarrolloN/phpmyadmin/ o por http://192.168.1.X/phpmyadmin/ (donde N es el número del servidor y X es el número de la IP asignada)e ingresar con el usuario root y la nueva contraseña del usuario root de MySQL que hemos creado.
