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

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/

1. wget http://haproxy.1wt.eu/download/1.3/src/haproxy-1.3.17.tar.gz
2. cd haproxy-1.3.17
3. make TARGET=linux26
4. cp /path/to/haproxy-1.3.17/examples/haproxy.init /etc/init.d/haproxy
5. chmod +x /etc/init.d/haproxy

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.

1. useradd haproxy
2. mkdir /var/chroot/haproxy
3. chown haproxy:haproxy /var/chroot/haproxy
4. chmod 700 /var/chroot/haproxy

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

1. global
2. maxconn     10000 # Total Max Connections.
3. log     127.0.0.1   local0
4. log     127.0.0.1   local1 notice
5. daemon
6. nbproc      1 # Number of processes
7. user        haproxy
8. group       haproxy
9. chroot      /var/chroot/haproxy
10. defaults
11. log     global
12. option      httplog
13. mode        tcp
14. clitimeout  60000
15. srvtimeout  30000
16. contimeout  4000
17. retries     3
18. redispatch
19. option      httpclose
20. listen  load_balanced   192.168.0.2:80,192.168.0.2:443
21. balance     source
22. option      ssl-hello-chk
23. option      forwardfor
24. server webserver1 192.168.0.10 weight 1 maxconn 5000 check
25. server webserver2 192.168.0.20 weight 1 maxconn 5000 check
26. listen  admin_stats 192.168.0.2:8080
27. mode        http
28. stats uri   /my_stats
29. stats realm     Global\ statistics
30. stats auth  username:password

Step 4: Configuring logging

Edit /etc/sysconfig/syslog

1. SYSLOGD_OPTIONS=”-m 0 -r”
