En la entrada anterior hemos visto como instalar Apache ahora continuamos y instalamos mysql (MariaDB).

Como instalar Apache

Como instalar PHP

• MariaDB(MySql)

  • En Debian Jessie el paquete de MariaDB ya viene incluido en los repositorios, pero si lo queremos en otra distribución tenemos que añadir las url al repositorio.
  • En está página explica como hay que hacerlo de 2 formas.
  • Hecho el proceso seguimos.

  • apt-get install mariadb-server

  • Una vez instalado ejecutamos el asistente de seguridad mysql_secure_installation para borrar permisos y la tabla de pruebas.
  • Las respuestas a las preguntas

    root@todoseaprende:/# mysql_secure_installation
    
    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): (Escribimos la contraseña que pusimos cuando instalamos MariaDB)
    OK, successfully used password, moving on...
    
    Setting the root password ensures that nobody can log into the MariaDB
    root user without the proper authorisation.
    
    You already have a root password set, so you can safely answer 'n'.
    
    Change the root password? [Y/n] n (Si quieres cambiar la contraseña anterior le dices que si)
    ... skipping.
    
    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] y (Quita los usuarios anónimos)
    ... 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 (Si nos queremos conectar con el usuario root remotamente le decimos que no)
    ... 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] y (Elimina la base de datos de pruebas)
    - 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 (Recarga los privilegios de las tablas)
    ... 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!

  • Y con esto ya tenemos instalado MariaDB(MySql)
  • Vamos a configurar MariaDB para que acepte conexiones remotas, que nos permitirá conectarnos con programas como (MySql Workbench, Navicat, Toad, etc…).

  • nano /etc/mysql/my.cnf

  • Buscamos la linea bind-address = 127.0.0.1, podemos hacer 2 cosas, comentar la linea añadiendo delante # o cambiando la ip, para saber que ip tiene la maquina utilizamos el comando ifconfig.
  • Ahora reinciamos el servicio

    service mysql restart

Y con esto ya tenemos configurado nuestro mysql.
