Server Deployment - Haproxy

Server Deployment - Haproxy

I will install the latest package in my system. I use it as software solution of hardware F5.

1. Install haproxy
download this file haproxy-1.4.15.tar.gz
unzip the file
>tar zxvf haproxy-1.4.15.tar.gz

move the file to work directory
>mv /home/luohua/soft_bak/haproxy-1.4.15 /home/luohua/tools/
>cd /home/luohua/tools/haproxy-1.4.15
compile the make file and install
>make TARGET=linux26
>make install

2. my configuration file, haproxy.conf:

global
    daemon
    maxconn 256
    log 127.0.0.1   local0
    debug
    #quiet

defaults
    log 127.0.0.1   local3
    mode http
    option httplog
    option httpclose
    option dontlognull
    option forwardfor
    option redispatch
    retries 2
    maxconn 2000
    balance roundrobin
    stats   uri     /haproxy-stats
    timeout connect 5000ms
    timeout client 50000ms
    timeout server 50000ms

listen web_proxy 0.0.0.0:82
        option httpchk GET /easymarket/index.jsp

        server s1 127.0.0.1:8083 weight 3 check
        server s2 127.0.0.1:8084 weight 3 check
        server s3 127.0.0.1:8085 weight 3 check

3. command to start the server
>haproxy -f haproxy.conf

I met a problem said:
Starting proxy web_proxy: cannot bind socket

my solution:
>vi /etc/sysctl.conf
net.ipv4.ip_nonlocal_bind=1

and start the haproxy with root or
>sudo haproxy -f haproxy.conf

4. We can see the status of this server on URL:
http://localhost:82/haproxy-stats
http://localhost:82/easymarket
