Mise en Place de l'Infrastructure
Connexion au Serveur Cloud
Pendant la durée de la formation, vous disposez d'un serveur dédié, pré-installé, pré-configuré et hébergé dans le cloud.
Linux, MacOS et Windows 10 muni du client ssh
Ouvrez un terminal ou CMD et tapez la commande suivante :
$ ssh -l desktop serverXX.ittraining.network
> ssh -l desktop serverXX.ittraining.network
où XX représente le numéro de votre serveur dédié. Entrez ensuite le mot de passe qui vous a été fourni.
Windows 7 et Windows 10 sans client ssh
Ouvrez putty et utilisez les informations suivantes pour vous connecter à votre serveur dédié :
- Host Name –> serverXX.ittraining.network
- Port –> 22
Au prompt, connectez-vous en tant que desktop avec le mot de passe qui vous a été fourni.
Configuration de Votre Serveur
Cette infrastructure doit être mise en place sur des serveurs bare metal avec les caractéristiques suivantes :
- XEON-SATA-2-64 Server - 8c/16t - Intel Xeon D-1540 - 64GB DDR4 ECC 2133MHz - 4x 2To HDD SATA Soft RAID
Dans le parc, les serveurs numéros 41 et plus sont compatibles.
Le serveur 40 est le serveur de référence. Remplacez XX par le numéro de votre serveur.
Téléchargement de la VM de base
Téléchargez la VM CentOS_7_8.ova :
desktop@serverXX:~$ cd Downloads desktop@serverXX:~/Downloads$ scp desktop@server40.ittraining.network:/home/desktop/Downloads/CentOS_7_8.ova .
Le mot de passe est Tk9ARhq48RQN
Importer la VM CentOS_7_8.ova
desktop@serverXX:~/Downloads$ VBoxManage import CentOS_7_8.ova --vsys 0 --eula accept desktop@serverXX:~/Downloads$ cd ~
