Why my Ldirectord check multiple times on read server every interval?
- by garconcn
I have a Ldirectord server and two real servers. My ldirectord used to check the request page on real server once in every interval, but now I found that it check four times. I have monitored the log on both real servers, they have the same problem.
Here is my ldirectord configuration:
checktimeout=10
checkinterval=5
autoreload=yes
logfile="/var/log/ldirectord.log"
quiescent=no
virtual=192.168.1.100:80
fallback=127.0.0.1:80
real=192.168.1.10:80 gate
real=192.168.1.20:80 gate
service=http
request="lb.html"
receive="still alive"
scheduler=sh
persistent=60
protocol=tcp
checktype=negotiate
Ldirectord will connect to each real server once every 5 seconds (checkinterval) and request 192.168.0.10:80/test.html (real/request).
The access log in real server:
