CentOS 6.5 安装haproxy

1、安装haproxy

#tar xzvf haproxy-1.5.9.tar.gz

#cd haproxy-1.5.9

# make TARGET=linux26 PREFIX=/usr/local/haproxy

# make install PREFIX=/usr/local/haproxy

# mkdir /usr/local/haproxy/etc

# mkdir -p /data/logs/haproxy

2、编辑haproxy 配置文件

# vi /usr/local/haproxy/etc/haproxy.conf

global

maxconn 4096

chroot /usr/local/haproxy

server web_mgr 192.168.0.2:9000 check inter 2000 rise 2 fall 2

3、编辑haproxy 服务脚本

#vi /etc/init.d/haproxy

#!/bin/sh

#chkconfig: 35 86 86

#description: HAProxy is a TCP/HTTP reverse proxy.

#processname: haproxy

# config: /usr/local/haproxy/etc/haproxy.conf

# pidfile: /usr/local/haproxy/haproxy.pid

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

BINFILE="/usr/local/haproxy/sbin/haproxy"

CFGFILE="/usr/local/haproxy/etc/haproxy.conf"

PIDFILE="/usr/local/haproxy/haproxy.pid"

LOCKFILE="/usr/local/haproxy/haproxy.lock"

RETVAL=0

start() {

[[ -x $BINFILE ]] || exit 5

[[ -f $CFGFILE ]] || exit 6

$BINFILE -c -q -f $CFGFILE

[[ $? -ne 0 ]] && echo "The HAProxy configure has error." && return 1

echo -n "Starting HAProxy......"

$BINFILE -f $CFGFILE -p $PIDFILE

RETVAL=$?

echo

[[ $RETVAL -eq 0 ]] && touch $LOCKFILE

return $RETVAL

}

stop() {

echo -n "Shutting down HAProxy......"

while true

killall $BINFILE

[[ -z `ps aux | grep sbin/haproxy | grep -v grep` ]] && break

done

RETVAL=$?

echo

[[ $RETVAL -eq 0 ]] && rm -f $LOCKFILE $PIDFILE

return $RETVAL

}

restart() {

stop

sleep 1

start

}

reload() {

[[ -z `ps aux | grep sbin/haproxy | grep -v grep` ]] && echo "The HAProxy is not running." && return 1

echo -n $"Reloading HAProxy......"

if [[ -f $PIDFILE ]]; then

$BINFILE -f $CFGFILE -st `cat $PIDFILE`

else

$BINFILE -f $CFGFILE -st `ps aux | grep sbin/haproxy | grep -v grep | awk '{print $2}'`

RETVAL=$?

echo

return $RETVAL

}

case "$1" in

start)

start

;;

stop)

stop

;;

restart)

restart

;;

reload)

reload

;;

condrestart)

[[ -e $LOCKFILE ]] && restart || :

;;

check)

$BINFILE -c -q -V -f $CFGFILE

;;

echo "Usage: service haproxy {start|stop|restart|reload|condrestart|check}"

RETVAL=1

esac

exit $RETVAL

4、编辑系统日志配置

# vim /etc/rsyslog.conf

默认有下面的设置，会读取 /etc/rsyslog.d/*.conf目录下的配置文件

$IncludeConfig /etc/rsyslog.d/*.conf

5、为haproxy创建一个独立的配置文件

# vim /etc/rsyslog.d/haproxy.conf

$ModLoad imudp

$UDPServerRun 514

local3.* /var/log/haproxy.log

#如果不加下面的的配置则除了在/var/log/haproxy.log中写入日志外，也会写入message文件

6、配置rsyslog的主配置文件，开启远程日志

# vim /etc/sysconfig/rsyslog

SYSLOGD_OPTIONS=" -c 2 -r -m 0"

#-c 2 使用兼容模式，默认是 -c 5

#-r 开启远程日志

#-m 0 标记时间戳。单位是分钟，为0时，表示禁用该功能

7、重启haproxy和rsyslog服务

#/etc/init.d/rsyslog restart

#/etc/init.d/haproxy restart

8、查看haproxy 状态

#/etc/init.d/haproxy status

haproxy 安装完成。
