RSync :
Les éléments présent dans serveur sont synchronisé sur websebp (qui centralise)
Configuration SSH
Sur les 2 noeuds (sous root) :
mkdir ~/.ssh chmod 700 ~/.sshClé RSA :
/usr/bin/ssh-keygen -t rsa
à Pas de passphrase
Clé DSA :
/usr/bin/ssh-keygen -t dsa
à Pas de passphrase
Création du fichier d’authorisation :
$ touch ~/.ssh/authorized_keys
Sur websebp (root) :cd .ssh ssh websebp cat /root/.ssh/id_rsa.pub >> authorized_keys ssh websebp cat /root/.ssh/id_dsa.pub >> authorized_keys ssh serveur cat /root/.ssh/id_rsa.pub >> authorized_keys ssh serveur cat /root/.ssh/id_dsa.pub >> authorized_keys scp authorized_keys serveur:/root/.ssh/ chmod 600 ~/.ssh/authorized_keys
Sur serveur (root):$cd .ssh ssh serveur cat /root/.ssh/id_rsa.pub >> authorized_keys ssh serveur cat /root/.ssh/id_dsa.pub >> authorized_keys
Sur websebp (root)scp serveur:/root/.ssh/authorized_keys .
Synchronisation /var/www sur “serveur vers /home/bdemolon/serveur
Sur websebp (root)
