主机: 192.168.122.119 server19.example.com

192.168.122.25 server25.example.com

192.168.122.163 server63.example.com

192.168.122.193 server93.example.com

所需的包:keepalived-1.2.7.tar.gz

Realserver1
192.168.122.163:apache

Realserver2
192.168.122.193:apache

Load
Balance 192.168.122.119:keepalived

Load
Balance 192.168.122.25:keepalived

Virtual
IP 192.168.122.178

以下步骤在server19和server25上实施:

[root@server19
~]# yum install kernel-devel make gcc -y

[root@server19
~]# yum install openssl-devel popt-devel -y

[root@server19
~]# yum install libnl-devel -y

以下步骤在server19或server25上实施:

[root@server19
kernel]# tar zxf keepalived-1.2.7.tar.gz

[root@server19
kernel]# cd keepalived-1.2.7

[root@server19
keepalived-1.2.7]# ./configure –prefix=/usr/local/keepalived

[root@server19
keepalived-1.2.7]# make && make install

[root@server19
keepalived-1.2.7]# scp -r /usr/local/keepalived/
root@192.168.122.25:/usr/local/

以下步骤在server19和server25上实施:

[root@server19
keepalived-1.2.7]# ln -s /usr/local/keepalived/etc/keepalived/ /etc/

[root@server19
keepalived-1.2.7]# ln -s
/usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

[root@server19
keepalived-1.2.7]# ln -s
/usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/

[root@server19
keepalived-1.2.7]# ln -s /usr/local/keepalived/sbin/keepalived
/sbin/

注：系统镜像的负载均衡套件中也集成了keepalived,也可以直接使用yum
install keepalived -y进行安装。但需先配置yum源：

[LoadBalancer]

name=Instructor

~]# /etc/init.d/arptables_jf save

[root@server63
~]# ifconfig eth0:0 192.168.122.178 netmask 255.255.255.255 up

或

[root@server63
~]# ip addr add 192.168.122.178 dev eth0

注：可用ip
addr show查看

[root@server63
~]# echo `hostname` > /var/www/html/index.html

[root@server63
~]# /etc/init.d/httpd start

以下步骤在server93上实施:

[root@server93
~]# yum install arptables_jf httpd -y

[root@server93
~]# arptables -A IN -d 192.168.122.178 -j DROP

[root@server93
~]# arptables -A OUT -s 192.168.122.178 -j mangle --mangle-ip-s

[root@server93
~]# ip addr add 192.168.122.178 dev eth0

注：可用ip
addr show查看

[root@server93
~]# echo `hostname` > /var/www/html/index.html

[root@server93
~]# /etc/init.d/httpd start

以下步骤在server19和server25上实施:

[root@server19
~]# /etc/init.d/keepalived start

测试:

执行ip
addr show可查看虚拟IP,执行ipvsadm
-l查看规则是否加载，访问192.168.122.178反复刷新网页,每次出现的页面都不同说明配置成功.
当主备挂掉后可由另一台接管,当两台都正常时由Master充当调度器.
