Hi there !
I have an emergency problem now , and I join this mail list expect
some help , thanks all of you !
The case scene:
user ----> public IP( supplied by a hardware firewall) ----->
public IP(supplied by LVS : NAT,rr) ----> 5 Real Servers(nginx、php-fpm)
----> Mysql
maybe you can see the hidden trouble , lvs only can see only one
client(one prublic IP , the hardware firewall)
The trouble is:
Sometimes , the request is very unbalanced !
lvs puts a lots of requests to 1 real server. And this poor、unlucky real
server have to handle 3 times more then others!
I count this from the nginx access.log
most of the times , lvs balances well!
I try to use LeastConn instead of RoundRobin, but doest effect.
(some one said the frewall and LVS should work in a LAN, why must I
use this architecture? Because some more cold backup firewalls are in
different IDC. to prevent DDOS and redundancy )
Any ideas ? Thanks very mych !
