##### Choix du serveur SSH

Je laisse par défaut avec OpenSSH

```shell
Which SSH server? ('openssh', 'dropbear' or 'none') [openssh]
```

##### Choix du disque d’installation

```shell
Available disks are:
  sda   (21.5 GB VMware,  VMware Virtual S)
Which disk(s) would you like to use? (or '?' for help or 'none') [none] sda
The following disk is selected:
  sda   (21.5 GB VMware,  VMware Virtual S)
```

##### Type d’installation pour Alpine Linux

La on ce trouve avec un choix important en fonction de l'usage que l'on veut en faire.

- sys : mode d’installation traditionnel sur disk avec /boot, / (filesystem root) et swap.
- data : seul seront les données stokées sur le disque, l'OS n'est pas installé car celui ci est lancé en mémoire.
- lvm : partition en lvm
- lvmsys : installation sys sur un volume en lvm
- lvmdata : installation data sur un volume en lvm

```shell
How would you like to use it? ('sys', 'data', 'lvm' or '?' for help) [?] ?

You can select between 'sys', 'data', 'lvm', 'lvmsys' or 'lvmdata'.

sys:
  This mode is a traditional disk install. The following partitions will be
  created on the disk: /boot, / (filesystem root) and swap.

  This mode may be used for development boxes, desktops, virtual servers, etc.

data:
  This mode uses your disk(s) for data storage, not for the operating system.
  The system itself will run from tmpfs (RAM).

  Use this mode if you only want to use the disk(s) for a mailspool, databases,
  logs, etc.

lvm:
  Enable logical volume manager and ask again for 'sys' or 'data'.

lvmsys:
  Same as 'sys' but use logical volume manager for partitioning.

lvmdata:
  Same as 'data' but use logical volume manager for partitioning.

The following disk is selected:
  sda   (21.5 GB VMware,  VMware Virtual S)
How would you like to use it? ('sys', 'data', 'lvm' or '?' for help) [?] sys
WARNING: The following disk(s) will be erased:
  sda   (21.5 GB VMware,  VMware Virtual S)
WARNING: Erase the above disk(s) and continue? [y/N]: y
Creating file systems...
Installing system on /dev/sda3:
/mnt/boot is device /dev/sda1
100% #########################==> initramfs: creating /boot/initramfs-lts
/boot is device /dev/sda1
```

##### Fin de l’installation

L’installation est terminer, on reboot pour démarrer sur l'OS fraîchement installé.  
Comme vous avez pu le constater, l'Alpine Linux est très léger au vu du temps d’installation.

```shell
Installation is complete. Please reboot.
```

##### Pour aller plus loin

Dans le cadre d'une installation automatisée, il est possible de créer un fichier de réponses pour ne pas avoir besoin d'interagir (et accessoirement aller boire un café :-) ) avec le programme d'installation.

Celui-ci peut-être créé à la main ou (plus simple) en ajoutant l'option **'-c &lt;le\_nom\_de\_mon\_fichier\_de\_reponses\_a\_creer&gt;'** à la commande **setup-alpine**.

```shell
setup-alpine -c answers
```

Le programme va effectuer toutes les étapes vues plus haut sans pour autant installer le système. Il en résultera un fichier **answers** avec tout les paramètres indiqués.

L'installation automatisée se fait via **'-f &lt;le\_nom\_de\_mon\_fichier\_de\_reponses\_precedemment\_cree&gt;'**, dans ce cas précis cela donne simplement:

```shell
setup-alpine -f answers
```

### **VMware tools**

Comme sur les autres distribution linux cela ce fait via le paquet : open-vm-tools. Mais il y a une subtilité chez Alpine, il faut démarrer le service manuellement et l'inscrire pour le démarrage.

#### Installation

```shell
alpine:~#  apk add --update open-vm-tools
fetch http://mirrors.ircam.fr/pub/alpine/v3.12/main/x86_64/APKINDEX.tar.gz

#### Lancement du service

```shell
alpine:~# rc-service open-vm-tools start
 * Starting open-vm-tools ...                                                                         [ ok ]
```

#### Démarrage automatique au boot

```shell
alpine:~# rc-update add open-vm-tools
 * service open-vm-tools added to runlevel default
```

# MariaDB

### Installation

```shell
apk add mariadb mariadb-common mariadb-client
```

### Initialisation

Il faut lancer la commande pour initialiser le service et créer la base SQL de départ.

```shell
alpine:~# rc-service mariadb setup
 * Creating a new MySQL database ...
Installing MariaDB/MySQL system tables in '/var/lib/mysql' ...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system


Two all-privilege accounts were created.
One is root@localhost, it has no password, but you need to
be system 'root' user to connect. Use, for example, sudo mysql
The second is mysql@localhost, it has no password either, but
you need to be the system 'mysql' user to connect.
After connecting you can set the password, if you would need to be
able to connect as any of these users with a password and without sudo

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd '/usr' ; /usr/bin/mysqld_safe --datadir='/var/lib/mysql'

You can test the MariaDB daemon with mysql-test-run.pl
cd '/usr/mysql-test' ; perl mysql-test-run.pl

Please report any problems at http://mariadb.org/jira

The latest information about MariaDB is available at http://mariadb.org/.
You can find additional information about the MySQL part at:

```

#### Inscription du service au boot

```shell
alpine:~# rc-update add mariadb default
 * service mariadb added to runlevel default
```

#### Lancement du service

```shell
alpine:~# rc-service mariadb start
 * Starting mariadb ...
200606 17:17:43 mysqld_safe Logging to syslog.
200606 17:17:43 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql                                             [ ok ]

```

#### Configuration

Il y a une petite subtilité, c'est **mariadb-secure-installation** même si *mysql\_secure\_instalation* est toujours présent.

```shell
alpine:~# mariadb-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
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] y
Enabled successfully!
Reloading privilege tables..
 ... Success!


You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password:
Re-enter new password:
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] y
 ... 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
 ... 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
 - 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] y
 ... 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!
