Installing haproxy load balancing for http and https--转载

This example will guide you through a simple IP based load balancing solution that handles ssl traffic.

The Configuration =

Load Balancer: <192.168.0.2> // will be our haproxy server

Web Server 1: <192.168.0.10> // web application server 1

Web Server 2: <192.168.0.20> // web application server 2

Admin Panel Port 8080: <192.168.0.2> // Statistics Panel on port 8080

Step 1: Get and Install haproxy

We’ll be using the 1.3.17 src files to install haproxy. You can get them from http://haproxy.1wt.eu/

wget http://haproxy.1wt.eu/download/1.3/src/haproxy-1.3.17.tar.gz
cd haproxy-1.3.17

make TARGET=linux26

cp /path/to/haproxy-1.3.17/examples/haproxy.init /etc/init.d/haproxy

chmod +x /etc/init.d/haproxy

Step 2: Create some users for security

We’re going to add a haproxy user and run it in a chroot jail. Be sure to read up on other security measures for your server.

useradd haproxy

mkdir /var/chroot/haproxy

chown haproxy:haproxy /var/chroot/haproxy

chmod 700 /var/chroot/haproxy

Step 3: Configure /etc/haproxy.cfg

This will be a simple load balancing. The HAProxy server will listen to 1 IP and distribute to 2 servers.

global

maxconn 10000 # Total Max Connections.

log 127.0.0.1 local0

log 127.0.0.1 local1 notice

daemon

nbproc 1 # Number of processes

user haproxy

group haproxy

chroot /var/chroot/haproxy

listen admin_stats 192.168.0.2:8080

mode http

stats uri /my_stats

stats realm Global\ statistics

stats auth username:password

Step 4: Configuring logging

Edit /etc/sysconfig/syslog

SYSLOGD_OPTIONS=”-m 0 -r”

Edit /etc/syslog.conf. Add the following:

local0.* /var/log/haproxy.log

local1.* /var/log/haproxy-1.log

Restart Syslog

service syslog restart
