I have apache 2.2 load-balancing a pool of 3 tomcat servers. I want
to replace it with nginx. I have the following very simple setup to
test the concept:
user nginx;
worker_processes 2;
error_log logs/error.log debug;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] $status
’
'“$request” $body_bytes_sent “$http_referer” ’
‘“$http_user_agent” “http_x_forwarded_for”’;
access_log logs/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
server {
listen 80;
server_name www.mysite.dmz;
large_client_header_buffers 4 16k;
access_log logs/host.access.log main;
# Main location
location / {
proxy_pass http://10.1.1.241:8080/;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
}
}
}
This seems to work ok, although I’ve not yet looked up what each thing
does. What I need it to do, which I had some problems doing with
apache is the following:
- Needs to loadbalance over 3 servers
- Sessions need to be sticky - so the user goes to the same server
all the time, after the session is started. - All http traffic needs to be coerced to https apart from
www.mysite.com/xml
Any pointers to example configs or bits of the documentation would be
most welcome. I’m just diving into the wiki now, but and handy
pointers would be a great help.
Thanks,
S.
