Vip: 172.16.168.35

Apache_one 172.16.168.30

Apache_two 172.16.168.37

备Keepalived 172.16.168.23

vip :172.16.168.38

Apache_two 172.16.168.36

要求：  访问172.16.168.35  能由172.16.168.30  172.16.168.37  来处理web请求

　　　　访问172.16.168.38  能由172.16.168.34  172.16.168.36  来处理web请求

一、主keepalived的配置

yum -y install kernel-devel openssl-devel popt-devel gcc ipvsadm   #安装支持库和lvs

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

Make && make install #编译

chkconfig keepalived on

配置文件/etc/keepalived/keeplived.com的内容为：

! 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 {

}

}

}

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 {

}

}

二、备keepalived的配置

yum -y install kernel-devel openssl-devel popt-devel gcc ipvsadm   #安装支持库和lvs

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

Make && make install #编译

chkconfig keepalived on

配置文件/etc/keepalived/keeplived.com的内容为：

! 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、四台apache的配置

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

DEVICE=lo:0

IPADDR=172.16.168.38 # 另外一组apache配172.16.168.35

NETMASK=255.255.255.255

ONBOOT=yes

NAME=loopback

chkconfig iptables  off

chkconfig httpd on

init 6
