實驗環境：

主Keepalived 172.16.168.24   

Vip: 172.16.168.35

Apache_one 172.16.168.30

Apache_two 172.16.168.37

 

備Keepalived 172.16.168.23

vip :172.16.168.38

Apache_two 172.16.168.36

 

要求：  訪問172.16.168.35  能由172.16.168.30  172.16.168.37  來處理web請求

　　　　訪問172.16.168.38  能由172.16.168.34  172.16.168.36  來處理web請求

 

一、主keepalived的配置

yum -y install kernel-devel openssl-devel popt-devel gcc ipvsadm   #安裝支持庫和lvs

./configure --prefix=/ --with-kernel-dir=/usr/src/kernels/2.6.32-431.el6.x86_64   /#配置

Make && make install #編譯

chkconfig keepalived on

配置文件/etc/keepalived/keeplived.com的內容為：

 

! Configuration File for keepalived

 

global_defs {

   notification_email {

    15888036388@163.com

   }

   notification_email_from Alexandre.Cassen@firewall.loc

   smtp_server localhost

   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 {

172.16.168.38

172.16.168.35

        

    }

}

 

virtual_server 172.16.168.38 80 {

    delay_loop 6

    lb_algo rr

    lb_kind DR 

    protocol TCP

 

    real_server 172.16.168.34 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

 

    real_server 172.16.168.36 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

}

 

virtual_server 172.16.168.35 80 {

    delay_loop 6

    lb_algo rr

    lb_kind DR

    !persistence_timeout 50

    protocol TCP

 

    real_server 172.16.168.30 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

 

    real_server 172.16.168.37 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

}

 

 

二、備keepalived的配置

yum -y install kernel-devel openssl-devel popt-devel gcc ipvsadm   #安裝支持庫和lvs

./configure --prefix=/ --with-kernel-dir=/usr/src/kernels/2.6.32-431.el6.x86_64  /#配置

Make && make install #編譯

chkconfig keepalived on

配置文件/etc/keepalived/keeplived.com的內容為：

! Configuration File for keepalived

 

global_defs {

   notification_email {

    15888036388@163.com

   }

   notification_email_from Alexandre.Cassen@firewall.loc

   smtp_server localhost

   smtp_connect_timeout 30

   router_id LVS_DEVEL

}

 

vrrp_instance VI_1 {

    state BACKUP

    interface eth0

    virtual_router_id 51

    priority 50

    advert_int 1

    authentication {

        auth_type PASS

        auth_pass 1111

    }

    virtual_ipaddress {

172.16.168.38

172.16.168.35

        

    }

}

 

virtual_server 172.16.168.38 80 {

    delay_loop 6

    lb_algo rr

    lb_kind DR 

    protocol TCP

 

    real_server 172.16.168.34 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

 

    real_server 172.16.168.36 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

}

 

virtual_server 172.16.168.35 80 {

    delay_loop 6

    lb_algo rr

    lb_kind DR

    !persistence_timeout 50

    protocol TCP

 

    real_server 172.16.168.30 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

 

    real_server 172.16.168.37 80 {

        weight 1

        TCP_CHECK {

            connect_port 80

            connect_timeout 3

            nb_get_retry 3

            delay_before_retry 3

        }

    }

}

 

 

三、四臺apache的配置

vim /etc/sysconfig/network-scripts/ifcfg-lo:0

DEVICE=lo:0

IPADDR=172.16.168.38 # 另外一組apache配172.16.168.35

NETMASK=255.255.255.255

ONBOOT=yes

NAME=loopback

 

chkconfig iptables  off

chkconfig httpd on

init 6
