I'm trying to use nginx for load balancing in my server.
Actually I have 2 servers in the same network with Apache listening the
port 8080 (http://IP:8080/ it's works!). In one of them i install nginx
to
send 50% of requests to one server and 50% to other. The configuration
looks like:
upstream mysite{
server 10.10.14.64:8080;
server 127.0.0.1:8080;
}
server {
server_name 10.10.14.66;
# pass all else onto apache waiting at localhost:8080
location / {
proxy_pass http://mysite;
}
}
When i run ''ab -c 100 -n 1000 http://10.10.14.66/prueba.php'', where
prueba.php only does ''phpinfo()''. The result show:
...
Complete requests: 1000
Failed requests: 499
(Connect: 0, Receive: 0, Length: 499, Exceptions: 0)
...
But if i run the same benchmark individually, there are 0 Fail requests.
Just commenting one server or the other from upstream nginx
configuration.
If i try with a html or jpg file don't get fail requests. But the times
don't improve with the 2 servers. If i does the test directly to port
8080 for each machine, i get 5-6 seg average, but if i does to nginx
with load balance, i get 7-8 seg average. It's that reasonable?
Can anyone help me?
