I have two servers running ldap with replication between them, now i need to install a loadbalancer, so what i have in mind is:
vm1: ldap1
vm2: ldap1(replication)
vm3: haproxy1 + keepalived
vm4: haproxy2 + keepalived
vm4 will be backup for vm3, and vm3 will be in charge of loadbalance for trafic towards vm1 and vm2.
My question is: can i install haproxy and keepalived on the same vms running ldap? soemthing like this:
vm1: ldap + haproxy(master) + keepalived
vm2: ldap(replication) + haproxy(slave) + keepalived
if the answer is yes, what are the pros and cons of each architecture?
