VMware上搭建lvs(DR)+keepalive （已解决）

标签：lvs keepalive

这个问题纠结了很久，现已解决，问题记录在：http://pmghong.blog.51cto.com/3221425/1201533

   最近在VMware上搭建lvs+keepalive，总是不成功，试了N多次，看了N多视频和资料，也换过不同版本的包，但结果还是那样，想请教高手帮忙看看到底是哪里出问题了。

我总共开启了4台虚拟机（2台Director,2台Real Server），用真机当客户端，下面是我的IP分配
IP分配
192.168.30.105            DR（主）
192.168.30.106            DR（从）
192.168.30.113            RS1
192.168.30.114            RS2
192.168.30.254            VIP

一、安装ipvsadm
# yum install popt popt-devel popt-static openssl-devel kernel-devel libnl libnl-devel
# tar xf ipvsadm-1.26.tar.gz
# cd ipvsadm-1.26
# make && make install
# ipvsadm

二、安装keepalive
# tar xf keepalived-1.2.7.tar.gz
# cd keepalived-1.2.7
# ./configure --prefix=/usr/local/keepalive --with-kernel-dir=/usr/src/kernels/2.6.32-279.el6.x86_64/
# cd /usr/local/keepalive/
# make && make install

# cd /usr/local/keepalive/
# cp etc/rc.d/init.d/keepalived  /etc/rc.d/init.d/
# cp etc/sysconfig/keepalived /etc/sysconfig/
# cp sbin/keepalived /usr/sbin/
# cp etc/keepalived/keepalived.conf etc/keepalived/keepalived.conf.bk
# vim etc/keepalived/keepalived.conf
! Configuration File for keepalived

global_defs {
  notification_email {

    failover@firewall.loc
    sysadmin@firewall.loc
  }
  notification_email_from Alexandre.Cassen@firewall.loc
  smtp_server 128.0.0.1
  smtp_connect_timeout 30
  router_id LVS_DEVEL
}

vrrp_instance VI_1 {
   state MASTER
   interface eth0
   virtual_router_id 51
   priority 100
   advert_int 1
   authentication {
       auth_type PASS
       auth_pass 1111
   }
   virtual_ipaddress {
       192.168.30.254
   }
}
virtual_server 192.168.30.254 80 {
   delay_loop 6
   lb_algo wlc
   lb_kind DR
   nat_mask 255.255.255.0
   persistence_timeout 50
   protocol TCP

   real_server 192.168.30.113 80 {
       weight 1
       TCP_CHECK {
       connect_timeout 10
       nb_get_retry 3
       connect_port 80
       }
   }
   real_server 192.168.30.114 80 {
       weight 1
       TCP_CHECK {
       connect_timeout 10
       nb_get_retry 3
       connect_port 80
       }
   }
}
配置完成后，启动keepalive

[root@server keepalive]# service keepalived start

Starting keepalived:                                       [  OK  ]

正常来说，到这里之后，查看lvs应该可以看到VIP在本机了，可是我的就是看不到：
[root@server ~]# ip addr show
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 00:0c:29:5f:bb:08 brd ff:ff:ff:ff:ff:ff
   inet 192.168.30.105/24 brd 192.168.30.255 scope global eth0
   inet6 fe80::20c:29ff:fe5f:bb08/64 scope link
      valid_lft forever preferred_lft forever

从上面输出信息看出VIP并不在本机上

查看日志，似乎也没有报错

不知道什么原因，求高手指点迷津,万分感谢！
