1.下载并安装软件包
yum -y install make gcc pcre*
mkdir -p /data/app_platform/haproxy/conf/
useradd -r haproxy -s /sbin/nologin
wget http://www.haproxy.org/download/1.4/src/haproxy-1.4.26.tar.gz
tar zxvf haproxy-1.4.26.tar.gz
cd haproxy-1.4.26
make TARGET=linux26 PREFIX=/data/app_platform/haproxy/
make install PREFIX=/data/app_platform/haproxy/
2.添加配置文件
/data/app_platform/haproxy/conf/haproxy.cfg
global chroot /data/app_platform/haproxy/share/ log 127.0.0.1 local3 info daemon user haproxy group haproxy pidfile /var/run/haproxy.pid nbproc 1 stats socket /tmp/haproxy level admin stats maxconn 20 node master_loadbalance1 description xxxx maxconn 65536 nosplice spread-checks 3 defaults option httpchk GET /php-fpm_status log global mode http option httpclose option abortonclose no option accept-invalid-http-response option allbackups #option http-server-close #option httplog #option log-health-checks #option tcp-smart-connect option tcpka option redispatch option forwardfor except 127.0.0.1 retries 3 timeout check 60s timeout connect 600s timeout http-keep-alive 600s timeout http-request 600s timeout queue 600s timeout server 600s timeout tarpit 60s timeout client 600s frontend game_pool 0.0.0.0:80 mode http no option accept-invalid-http-request option http-server-close log global option log-separate-errors #option forwardfor except 127.0.0.1 header X-Real-IP option forwardfor except 127.0.0.1 # acl path_web_inf path_beg -i /WEB-INF # block if path_web_inf acl game_url hdr_reg(host) -i ^(s\d*.xxxx.com|s\d*.xxx.com|s\d*.xxx.com|s\d*.xxx.com)$ backend game_pool mode http balance roundrobin cookie SERVERID insert indirect # http-check disable-on-404 # http-check send-state # option httpchk GET /check.php HTTP/1.1\r\nHost:\ example.com default-server inter 2s fastinter 1s downinter 5s slowstart 60s rise 2 fall 5 weight 30 server xxx-taiwan-game1 192.168.1.183:80 cookie xxx-taiwan-game1_80 check maxconn 2000 server xxx-taiwan-game2 192.168.1.184:80 cookie xxx-taiwan-game2_80 check maxconn 2000 listen monitor1 0.0.0.0:10443 mode http balance roundrobin stats enable stats uri /nc-haproxy # - default is haproxy?stats stats realm Haproxy\ statistics # - Enable statistics and set authentication realm stats show-desc example gintama-taiwan-lb1 status page stats auth ncadmin:taiwan stats refresh 30s stats show-legends # - Enable reporting additional informations on the statistics page timeout check 10s timeout client 45s timeout connect 45s timeout http-keep-alive 45s timeout http-request 45s timeout queue 45s timeout server 45s timeout tarpit 45s
3.添加启动脚本
#!/bin/sh
#
# haproxy
#
# chkconfig: - 85 15
# description: HAProxy is a free, very fast and reliable solution # offering high availability, load balancing, and # proxying for TCP and HTTP-based applications
# processname: haproxy
# config: /data/app_platform/haproxy/conf/haproxy.cfg
# pidfile: /var/run/haproxy.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
exec="/data/app_platform/haproxy/sbin/haproxy"
prog=$(basename $exec)
conf_file="/data/app_platform/haproxy/conf/haproxy.cfg"
[ -e /etc/sysconfig/$prog ] && . /etc/sysconfig/$prog
lockfile=/var/lock/subsys/haproxy
check() {
$exec -c -V -f $conf_file
}
start() {
$exec -c -q -f $conf_file
if [ $? -ne 0 ]; then
echo "Errors in configuration file, check with $prog check."
return 1
fi
echo -n $"Starting $prog: "
# start it up here, usually something like "daemon $exec"
daemon $exec -D -f $conf_file -p /var/run/$prog.pid
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
# stop it here, often "killproc $prog"
killproc $prog
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
$exec -c -q -f $conf_file
if [ $? -ne 0 ]; then
echo "Errors in configuration file, check with $prog check."
return 1
fi
stop
start
}
reload() {
$exec -c -q -f $conf_file
if [ $? -ne 0 ]; then
echo "Errors in configuration file, check with $prog check."
return 1
fi
echo -n $"Reloading $prog: "
$exec -D -f $conf_file -p /var/run/$prog.pid -sf $(cat /var/run/$prog.pid)
retval=$?
echo
return $retval
}
force_reload() {
restart
}
fdr_status() {
status $prog
}
case "$1" in
start|stop|restart|reload)
$1
;;

force_reload

;;
condrestart|try-restart)
[ ! -f $lockfile ] || restart
;;
*)
echo $"Usage: $0 {start|stop|status|restart|try-restart|reload|force-reload}"
exit 2
esac4.添加日志输出
/etc/rsyslog.d/haproxy.conf
local3.* /var/log/haproxy.log $ModLoad imudp $UDPServerAddress 127.0.0.1 $UDPServerRun 514
service rsyslog restart
5.启动HAProxy
service haproxy start
tail -f /var/log/haproxy.log Feb 9 17:43:53 127.0.0.1 haproxy[25770]: backend game_pool has no server available! Feb 9 17:44:02 127.0.0.1 haproxy[25810]: Proxy game_pool started.

Feb 9 17:44:05 127.0.0.1 haproxy[25829]: backend game_pool has no server available!
6.设置HAProxy开机启动
chkconfig --level 35 haproxy on
