I find keepalived much more easy to use to configure my director. Here is my
entry for the fwmark rule :
virtual_server [RIP masked here] fwmark 1 {
delay_loop 20
lb_algo rr
lb_kind DR
persistence_timeout 1800
persistence_granularity 255.255.255.0
protocol TCP
virtualhost www.toto.com
real_server 172.16.1.4 80 {
weight 1
HTTP_GET {
url {
path /index.jsp
}
connect_port 8083
connect_timeout 10
nb_get_retry 5
delay_before_retry 20
}
}
}
And here is it for the "standard users" :
virtual_server [VIP really masked, for sure] 80 {
delay_loop 20
lb_algo rr
lb_kind DR
persistence_timeout 1800
persistence_granularity 255.255.255.0
protocol TCP
virtualhost www.toto.com
real_server 172.16.1.4 80 {
weight 1
HTTP_GET {
url {
path /index.jsp
}
connect_port 8083
connect_timeout 10
nb_get_retry 5
delay_before_retry 20
}
}
real_server 172.16.1.5 80 {
weight 1
HTTP_GET {
url {
path /index.jsp
}
connect_port 8083
connect_timeout 10
nb_get_retry 5
delay_before_retry 20
}
}
}
So, in one file, you have both you're load balancing and you're HA settings. Of
course, you need to configure iptables by yourself. Also, it doesn't do
anything on the realservers (but on the realservers, I just need to configure
the VIPs and noarpctl things, which is easy).
I like it.
