Hi Everybody,
I have a problem with network HA architecture, and I want to have your
feeling.
I have two web server (W1 and W2), the two one have public IP. My goal
is to add high availibity between this two server.
Here the network :
INTERNET
SWITCH
SWITCH
|
\ / |
|
\ / |
|
X |
|
/ \ |
|
/ \ |
WEB 1
WEB 2
The problem I have are :
- I can't change public IP to private IP (for web1 et web2)
- I can't add a box between the switches and the web servers
My idea is to add LVS on WEB1. The request will arrive to web1 which
will load-balancing it between him-self and web2. (is it possible?).
The problem is, if web1 crash, there are lots a chance that lvs will
crash too. So request are lost. So my second idea, is to add monitor on
web2 so that if web1 crash, web2 reconfigure it-self like web1 (same
IP).
I think that LVS-DR is the right method for LVS.
Is someone found mistake on my idea ? Is someone have already done that
or have another better solution ?
