Lvs(DR) +keepalived的架构部署

IP地址规划：

1.环境的大家和软件的安装

检查Linux内核版本是否支持ipvsadm模块

(1)源码编译安装

wgethttp://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz

wget http://www.keepalived.org/software/keepalived-1.1.17.tar.gz

uname -r                             (查看内核版本，下面的要和查看到的内核版本一样)

ln -s/usr/src/kernels/2.6.32-358.23.2.el6.x86_64/ /usr/src/linux   (如果/usr/src/kernels下面没有内容，可使用yum-y install kernel-devel安装即可)

2)安装依赖包

yum -y  install  openssl-devel librarie*  popt-devel

3)安装主要软件

tar -zxvf ipvsadm-1.24.tar.gz

cd ipvsadm-1.24

make && make install

cd ..

tar -zxvf keepalived-1.1.17.tar.gz

cd keepalived-1.1.17

./configure

make && make install

编译的时候出现这个提示，说明keepalived和内核结合了，如果不是这样的，需要加上这个参数./configure --with-kernel-

dir=/kernel/path

Keepalived configuration

------------------------

Keepalived version       : 1.1.17

Compiler                 : gcc

Compiler flags           : -g -O2

Extra Lib                : -lpopt -lssl -lcrypto

 UseIPVS Framework       : Yes

IPVS sync daemon support : Yes

Use VRRP Framework       : Yes

Use LinkWatch            : No

Use Debug flags          : No

(2)yum配置安装

yum -y install ipvsadm

yum -y install keepalived

进行安装即可，用yum安装完直接进行修改配置文件即可

2.配置单实例的lvs的DR模型

（1）手动配置

配置顺利我们关闭iptbales 和seLinux

Service iptables stop

Setenforce 0

（2）配置配置director的服务器的192.168.201.176的vip 192.168.201.170

Ifconfig  eht0:0192.168.201.170  netmask 255.255.255.0 up

添加路由route  add  –host  192.168.201.170  dev eth0:0

（2）配置RealServer1和Real Server2

设置vip4的配置

开启arp防护

cd /proc/sys/net/ipv4/conf/

修改

sysctl -w net.ipv4.conf.eth0.arp_announce=2

sysctl -w net.ipv4.conf.all.arp_announce=2

echo 1 >/proc/sys/net/ipv4/conf/eth0/arp_ignore

echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore

配置RealServer1 的vip  lo:0

Ifconfig lo:0 192.168.201.170  broadcast192.168.201.1  netmask 255.255.255.255 up

Route add  -host  192.168.201.170  dev lo:0

安装httpd服务

yum install httpd –y

修改index.html主页面

echo ‘zzx.178.com‘ >/var/www/html/index.html

service httpd restart

配置Real Server2 的vip  lo:0

Ifconfig  lo:0192.168.201.170  broadcast192.168.201.1  netmask 255.255.255.255 up

Route  add  -host 192.168.201.170  dev  lo:0

安装httpd服务

yum install httpd –y

修改index.html主页面

echo ‘zzx.179.com‘ >/var/www/html/index.html

service httpd  restart

3．配置lvs的Director Server1wcl

添加ipvsadm规则

ipvsadm -C --清空

ipvsadm -A -t 192.168.201.170:80 -s rr --统计

ipvsadm -a -t 192.168.201.170:80 -r192.168.201.179 -g -w 2 --配置权重

ipvsadm -a -t 192.168.201.170:80 -r192.168.201.178 -g -w 1 --配置权重

ipvsadm -L -n  --查看链接数

ipvsadm -L -n --stats -查看速率

查看结果：

测试结果

4.配置lvs+keepalived的架构

配置keepalived 的主备模式

176为keepalived主state MASTER

177为keepalived备state BACKUP

修改virtual_router_id主和备不要一致

vi /etc/keepalived/keepalived.conf

!Configuration File for keepalived

global_defs {

router_id LVS_DEVEL

}

# VIP1

vrrp_instance VI_1 {

state MASTER

interface eth0

lvs_sync_daemon_intefaceeth0

virtual_router_id 67

priority 100

advert_int 5

authentication {

auth_type PASS

auth_pass 1122

}

virtual_ipaddress {

192.168.201.170

}

}

virtual_server192.168.201.170 80 {

delay_loop 6

lb_algo rr

lb_kind DR

persistence_timeout 60

protocol TCP

real_server 192.168.201.178 80 {

# weight 100

TCP_CHECK {

connect_timeout 10

nb_get_retry 3

delay_before_retry 3

connect_port 80

}

}

real_server 192.168.201.179 80 {

# weight 100

TCP_CHECK {

connect_timeout 10

nb_get_retry 3

delay_before_retry 3

connect_port 80

}

}

}

重启keepalived

/etc/init.d/keepalived/  restart

验证效果

请大家多多指导,谢谢
