Willy Tarreau4689ae62007-11-30 15:23:38 +01001# This is a test configuration.
2# It makes use of a farm built from 4 active servers and 4 backup servers,
3# all listenening to different IP addresses on port 80. Health-checks are
4# TCP only on port 81 so that iptables rules permit easy selection of which
5# servers are enabled or disabled. It checks for the file /alive, and disables
6# the server if the response is 404.
7#
8# Create statistics counters this way :
9#
10# iptables -N http
11# iptables -A OUTPUT -p tcp --syn --dport 80 -j http
12# for i in $(seq 1 8); do iptables -A http -d 127.0.0.$i; done
13# iptables -A http -d 127.0.0.0/24
14#
15# Consult the statistics using iptables this way:
16#
17# iptables --line-numbers -nxvL http
18# iptables -Z http
19#
20# Block individual servers like this :
21# iptables -I INPUT -p tcp --dport 81 -d 127.0.0.1 -j DROP
22#
23# Enable each server like this :
24# touch $SRV_ROOT/alive
25#
26# Disable each server like this :
27# rm -f $SRV_ROOT/alive
28#
