部署高可用
業務需求描述
假設有兩臺服務器data-1-1/data-1-2 其實際ip分別為192.168.0.107和192.168.0.108（data-1-2），
配置目標，要求heartbeat服務啟動后，data-1-1初始啟動vip192.168.0.07，data-1-2初始啟動vip192.168.0.08.
一旦任意一臺服務器宕機，在宕機的機器上初始啟動的虛擬vip就會切換到運轉正常的機器上，實現了ip資源的
自動接管，從而達到高可用的目的
環境里的虛擬機雙網卡橋接
[root@localhost ?~]# setup空格切換

那么
[root@localhost ?~]# chkconfig NetworkManager off
[root@localhost ?~]# service NetworkManager stop
分別配置主機名與hosts
[data-1-1]
[root@localhost ~]# hostname data-1-1
[root@localhost etc]# vi /etc/sysconfig/network
HOSTNAME=data-1-1
[root@localhost etc]# cd /etc
[root@localhost etc]# cp hosts hosts_bak
[root@localhost etc]#vi hosts
127.0.0.1?? localhost localhost.localdomain localhost4 localhost4.localdomain4
::1???????? localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.107? data-1-1
192.168.88.108? data-1-2?? ?
[root@data-1-1 ~]# tail -2 /etc/hosts
192.168.0.107??? data-1-1
192.168.0.108??? data-1-2
[root@data-1-1 ~]# uname -n
data-1-1

[data-1-2]
[root@localhost ~]# hostname data-1-2
[root@localhost etc]# vi /etc/sysconfig/network
HOSTNAME=data-1-2
[root@localhost etc]# cd /etc
[root@localhost etc]# cp hosts hosts_bak
[root@localhost etc]#vi hosts

[root@data-1-2 ~]# tail -2 /etc/hosts
192.168.0.107??? data-1-1
192.168.0.108??? data-1-2
[root@data-1-2 ~]# uname -n
data-1-2
[root@data-1-1 ~]# ifconfig eth1[若ip為broadcast]就 ifup eth1；同理data-1-2
eth1????? Link encap:Ethernet? HWaddr 00:0C:29:34:72:3F ?
????????? inet addr:192.168.1.107? Bcast:10.0.10.255? Mask:255.255.255.0

添加主機路由
[data-1-1]
[root@data-1-1 ~]# route add -host 192.168.1.108 dev eth1 [/sbin/route add -host 192.168.1.108 dev eth1]
[root@data-1-1 ~]# route -n
Kernel IP routing table
Destination???? Gateway???????? Genmask???????? Flags Metric Ref??? Use Iface
192.168.1.108?????? 0.0.0.0???????? 255.255.255.255 UH??? 0????? 0??????? 0 eth1已經配置好了

echo '/sbin/route add -host 192.168.1.108 dev eth1' >>/etc/rc.local永久生效
[data-1-2]
[root@data-1-2 ~]# route add -host 192.168.1.107 dev eth1 [/sbin/route add -host 192.168.1.107 dev eth1]
