Installing haproxy load balancing for http and https--运维网
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
Web Server 1
Load Balancer <
Web Server 2
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
[*]
[*]defaults
[*] log global
[*] option httplog
[*] mode tcp
[*] clitimeout60000
[*] srvtimeout30000
[*] contimeout4000
[*] retries 3
[*] redispatch
[*] option httpclose
[*]
[*]listenload_balanced 192.168.0.2:80,192.168.0.2:443
[*] balance source
[*] option ssl-hello-chk
[*] option forwardfor
[*]
[*] server webserver1 192.168.0.10 weight 1 maxconn 5000 check
[*] server webserver2 192.168.0.20 weight 1 maxconn 5000 check
[*]
[*]listenadmin_stats 192.168.0.2:8080
[*] mode http
[*] stats uri /my_stats
[*] stats realm Global\ statistics
[*] stats authusername: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
