CentOS 5.9下安装配置Keepalived(4)

virtual_server 10.10.10.2 1358 {
    delay_loop 6
    lb_algo rr
    lb_kind NAT
    persistence_timeout 50
    protocol TCP

sorry_server 192.168.200.200 1358

real_server 192.168.200.2 1358 {
        weight 1
        HTTP_GET {
            url {
              path /testurl/test.jsp
              digest 640205b7b0fc66c1ea91c463fac6334d
            }
            url {
              path /testurl2/test.jsp
              digest 640205b7b0fc66c1ea91c463fac6334d
            }
            url {
              path /testurl3/test.jsp
              digest 640205b7b0fc66c1ea91c463fac6334d
            }
            connect_timeout 3
            nb_get_retry 3
            delay_before_retry 3
        }
    }

real_server 192.168.200.3 1358 {
        weight 1
        HTTP_GET {
            url {
              path /testurl/test.jsp
              digest 640205b7b0fc66c1ea91c463fac6334c
            }
            url {
              path /testurl2/test.jsp
              digest 640205b7b0fc66c1ea91c463fac6334c
            }
            connect_timeout 3
            nb_get_retry 3
            delay_before_retry 3
        }
    }
}

5、配置主备keepalived

a、配置主备keepalived
#主，以下主要列出keepalived.conf差异部分
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 {
        192.168.1.220
        192.168.1.230
    }
}

#备，以下主要列出keepalived.conf差异部分
vrrp_instance VI_1 {
    state BACKUP
    interface eth0
    virtual_router_id 51
    priority 90
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.1.220
        192.168.1.230
    }
}

b、测试主备keepalived
#启动主服务器上的keepalived服务
[root@MASTER ~]# service keepalived start
Starting keepalived: [  OK  ]

[root@SZ-SYS-APP01 ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 192.168.1.65/24 brd 192.168.1.255 scope global eth0
    inet 192.168.1.220/32 scope global eth0    #可以看到220和230的虚IP

      valid_lft forever preferred_lft forever
3: sit0: <NOARP> mtu 1480 qdisc noop
    link/sit 0.0.0.0 brd 0.0.0.0

#启动备用服务器上的keepalived服务
[root@BACKUP ~]# service keepalived start
Starting keepalived: [  OK  ]
#下面的查询结果中，虚IP220和230并为出现在备用服务器
[root@HKBO ~]# ip addr

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