haproxy+keepalive 实现jboss负载均衡和高可用
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
# pwd
/usr/local/jboss/server/jboss-ghl/deploy/ghn.war/WEB-INF
# cat jboss-web.xml
PUBLIC "-//JBoss//DTD Web Application 2.3V2//EN"
"http://www.jboss.org/j2ee/dtd/jboss-web_3_2.dtd">
/
你的域名
192.168.1.63
/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" />
然后写启动的脚本了
为了方便测试，写了一测试页
# cat index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
information from 192.168.1.60（63上面改成63的ip）
# pwd
/usr/local/jboss/server/jboss-ghl/deploy/ghn.war
# 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
# 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)
# cat haproxy.cfg
global
log 127.0.0.1 local0 info
maxconn 65536
chroot /var/lib/haproxy
pidfile /var/run/haproxy.pid
user haproxy

option httplog
option dontlognull

option forwardfor except 127.0.0.0/8
option redispatch

timeout queue 1m
timeout connect 10s
timeout client 1m

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
# 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
# ip add
1: lo: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:
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: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:
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
down掉主的keeplived，从的会立即接管浮动ip。实现无缝连接
