系统为centos 6.4 64位

主:192.168.1.61

备:192.168.1.62

浮动ip:192.168.1.64

realserver:192.168.1.60和192.168.1.63

第一:jboss的安装配置:

 yum install java-1.7.0* -y 

 unzip jboss-5.1.0.GA.zip  -d /usr/local

ln -sv jboss-5.1.0.GA   jboss

cd /usr/local/jboss/server

cp -r default default_init

cp -r default jboss-gh1(项目的目录)

把项目的包放在 jboss-gh1目录下

修改配置文件让其能用域名访问

[root@localhost WEB-INF]# pwd 

/usr/local/jboss/server/jboss-ghl/deploy/ghn.war/WEB-INF

[root@localhost WEB-INF]# cat jboss-web.xml 

<?xml version=‘1.0‘ encoding=‘UTF-8‘ ?>

<!DOCTYPE jboss-web

     PUBLIC "-//JBoss//DTD Web Application 2.3V2//EN"

          "http://www.jboss.org/j2ee/dtd/jboss-web_3_2.dtd">

          <jboss-web>

          <context-root>/</context-root>

          <virtual-host>你的域名</virtual-host>

          <virtual-host>192.168.1.63</virtual-host>

          </jboss-web


/usr/local/jboss/server/jboss-ghl/deploy/jbossweb.sar/server.xml

<Host name="你的域名" autoDeploy="false"

                  deployOnStartup="false" deployXML="false"> 

               <Valve className="org.apache.catalina.valves.AccessLogValve"

                      prefix="localhost_access_log."

                      suffix=".log"

                      pattern="common"

                      directory="${jboss.server.log.dir}"

                      resolveHosts="false" /> 

         </Host>

      </Engine>


   </Service>


</Server>

然后写启动的脚本了

为了方便测试,写了一测试页

[root@localhost ghn.war]# cat index.jsp 

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<?xml version="1.0" encoding="utf-8" ?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

 <title></title>

</head>

  <body>

   information from 192.168.1.60(63上面改成63的ip)

  </body>

</html>

[root@localhost ghn.war]# pwd 

/usr/local/jboss/server/jboss-ghl/deploy/ghn.war

[root@localhost bin]# cat jboss-gh1.sh 

#!/bin/bash

/usr/local/jboss/bin/run.sh -c jboss-ghl -b 0.0.0.0 -Djboss.service.binding.set=ports-01 -Djboss.messaging.ServerPeerID=1

[root@localhost bin]# pwd 

/usr/local/jboss/bin

./jboss-gh1.sh &启动进程

到此jboss的配置完成。

第二:haproxy和keepalive的配置

haproxy和keepalived都是直接yum安装的

 haproxy的配置(主从都是一样的)

[root@localhost haproxy]# cat haproxy.cfg

global

        log 127.0.0.1 local0 info

        maxconn 65536

       chroot      /var/lib/haproxy

       pidfile     /var/run/haproxy.pid

       user        haproxy

       group       haproxy

        daemon

        nbproc 4


defaults

    mode                    http

    log                     global

    option                  httplog

    option                  dontlognull

    option http-server-close

    option forwardfor       except 127.0.0.0/8

    option                  redispatch

    retries                 3

    timeout http-request    10s

    timeout queue           1m

    timeout connect         10s

    timeout client          1m

    timeout server          1m

    timeout http-keep-alive 10s

    timeout check           10s

    clitimeout              30000

    srvtimeout              30000

    contimeout              30000




frontend    60_ha

    bind  *:80

   mode http

   log global

   option httplog

   option dontlognull

   option forwardfor

   option httpclose

   clitimeout 60000

acl test  path_beg  /ghn

acl test1   hdr_dom(host) -i 你的域名



use_backend istest  if test or test1

backend istest

balance roundrobin

mode http

log global

option httplog

option httpclose

option forwardfor

contimeout 30000

srvtimeout 30000

fullconn 4000

server jbosstest1 192.168.1.60:8180 cookie c1 check inter 9000 rise 2 fall 3 weight 1 maxconn 2000

server jbosstest2 192.168.1.63:8180 cookie c1 check inter 9000 rise 2 fall 3 weight 1 maxconn 2000

service haproxy start 直接启动即可

keepalived的配置

主配置

[root@localhost keepalived]# cat keepalived.conf

! Configuration File for keepalived

global_defs {

router_id LVS_DEVEL

}

vrrp_instance VI_1 {

state MASTER

interface eth0

virtual_router_id 51

priority 150

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

192.168.1.64

}

}

备的配置

! Configuration File for keepalived

global_defs {

router_id LVS_DEVEL

}

vrrp_instance VI_1 {

state backup

interface eth0

virtual_router_id 51

priority 100

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

192.168.1.64

}

}

service keepalived start直接启动即可

启动之后 在主的上面 查看ip地址

[root@localhost keepalived]# ip add 

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 127.0.0.1/8 scope host lo

    inet6 ::1/128 scope host 

       valid_lft forever preferred_lft forever

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000

    link/ether 52:54:00:3b:2d:8c brd ff:ff:ff:ff:ff:ff

    inet 192.168.1.61/24 brd 192.168.1.255 scope global eth0

    inet 192.168.1.64/32 scope global eth0

    inet6 fe80::5054:ff:fe3b:2d8c/64 scope link 

       valid_lft forever preferred_lft forever

备的ip地址

root@localhost keepalived]# ip add 

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 127.0.0.1/8 scope host lo

    inet6 ::1/128 scope host 

       valid_lft forever preferred_lft forever

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000

    link/ether 52:54:00:6f:b9:8d brd ff:ff:ff:ff:ff:ff

    inet 192.168.1.62/24 brd 192.168.1.255 scope global eth0

    inet6 fe80::5054:ff:fe6f:b98d/64 scope link 

       valid_lft forever preferred_lft forever

第三:测试

绑定hosts文件

192.168.1.64  你的域名

bubuko.com,布布扣

bubuko.com,布布扣


down掉主的keeplived,从的会立即接管浮动ip。实现无缝连接
