J'ai compilé et configuré keepalived
mais elle ne démarre pas.
Voici ma configuration de base ;
vrrp_sync_group PUBLIC_WEB_IPS {
group {
public_http_ip_lan
}
}
vrrp_instance public_http_ip_lan {
state MASTER
interface br1118
virtual_router_id 18
priority 100
advert_int 1
virtual_ipaddress {
192.168.0.254/24 dev br1118
}
nopreempt
}
Lorsque je démarre keepalived, je n'obtiens aucune erreur, mais il semble qu'il y ait la plupart du temps une attente au démarrage, puis des pauses/arrêts ? Voici l'extrait de /var/log/syslog au démarrage keepalived

Rien n'apparaît dans tcpdump lorsque je démarre keepalived, aucune publicité par exemple :
user@basil:~$ sudo tcpdump -nlASX -s 0 -vvv -e src net 192.168.0.0/24 and not port 22tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes
L'interface du pont est en place (car elle fonctionne sur un vlan séparé) ;
user@basil:/usr/local/etc/keepalived$ ip a s br1118

Je peux envoyer un ping aux hôtes de ce VLAN. Qu'est-ce qui se passe ici ? Je pense que j'ai fait une erreur stupide, mais je ne vois rien d'anormal.
UPDATE :

Je viens de redémarrer cette boîte, c'est pourquoi les compteurs de trafic sont bas.
