VIP

heartbeat01.contoso.com

Heartbeat节点1

eth0:192.168.49.133

eth1:172.16.49.133(心跳连接)

172.16.49.100

heartbeat02.contoso.com

Heartbeat节点2

eth0:192.168.49.134

eth1:172.16.49.134(心跳连接)

一、准备工作

以下操作除非特别指明，否则均需在两台服务器上操作。

# 关闭iptables防火墙并禁用SELinux
/etc/init.d/iptables stop
chkconfig iptables off
sed -i ‘/^SELINUX/s/enforcing/disabled/‘ /etc/selinux/config
setenforce 0

# 设置时间同步
crontab -e  # 添加计划任务
0 * * * * /usr/sbin/ntpdate   210.72.145.44 64.147.116.229 time.nist.gov
:wq
或者
echo ‘0 * * * * /usr/sbin/ntpdate   210.72.145.44 64.147.116.229 time.nist.gov‘ >>/var/spool/cron/root  # 添加计划任务
crontab -l  # 检查计划任务是否存在
0 * * * * /usr/sbin/ntpdate   210.72.145.44 64.147.116.229 time.nist.gov

# 设置主机名（以heartbeat01为例，heartbeat02同样的方法）
sed -i ‘/^HOSTNAME/s/^/#/‘ /etc/sysconfig/network  
sed -i ‘/#HOSTNAME/aHOSTNAME=heartbeat01.contoso.com‘ /etc/sysconfig/network
grep HOSTNAME /etc/sysconfig/network
hostname heartbeat01.contoso.com
或者
sed -i ‘/^HOSTNAME/d‘ /etc/sysconfig/network
echo ‘HOSTNAME=heartbeat01.contoso.com‘ >>/etc/sysconfig/network
grep HOSTNAME /etc/sysconfig/network
hostname heartbeat01.contoso.com

# 编辑/etc/hosts文件
echo -e ‘192.168.49.133  heartbeat01.contoso.com\n192.168.49.134  heartbeat02.contoso.com‘ >>/etc/hosts
tail -2 /etc/hosts

# 添加一条主机路由
/sbin/route add -host 172.16.49.134 dev eth1 # 在heartbeat01上配置
echo ‘/sbin/route add -host 172.16.49.134 dev eth1‘ >>/etc/rc.local # 在heartbeat01上配置
/sbin/route add -host 172.16.49.133 dev eth1 # 在heartbeat02上配置
echo ‘/sbin/route add -host 172.16.49.133 dev eth1‘ >>/etc/rc.local # 在heartbeat02上配置
route -n #添加之后分别在heartbeat01和heartbeat02上检查

二、安装heartbeat软件

rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum -y install heartbeat*

三、编辑heartbeat配置文件

1）拷贝配置文件

cp /usr/share/doc/heartbeat-3.0.4/{ha.cf,haresources,authkeys} /etc/ha.d/
ll /etc/ha.d/
cd /etc/ha.d/

2）配置authkeys

[root@heartbeat01 ha.d]# egrep -v "#|^$" authkeys

auth 2

2 sha1 c6091592594cd14c

[root@heartbeat02 ha.d]# egrep -v "#|^$" authkeys

auth 2

2 sha1 c6091592594cd14c

# 两个节点的配置一致

3）配置ha.cf

下面以使用单播的方式为例，给出两个节点的配置：

[root@heartbeat01 ha.d]# egrep -v "#|^$" ha.cf

debugfile /var/log/ha-debug #设置debug文件位置

logfile /var/log/ha-log #设置日志文件位置

logfacility local1 #设置记录日志的设备

keepalive 2 #设置发送心跳报文的时间间隔

deadtime 30 #设置确认对端死亡的时间间隔

warntime 10 #设置发出最后的心跳警告报文的间隔

initdead 60 #设置初始化时间

ucast eth1 172.16.49.134 #设定侦听的心跳线的接口和对应的对端接口的IP地址

auto_failback on #启用自动恢复模式，当拥有该资源的属主恢复之后，属主将回收该资源

node heartbeat01.contoso.com #指定节点1，节点的名称一定要和uname -n的结果一致

node heartbeat02.contoso.com #指定节点2

ping 172.16.49.1 #指定第三方仲裁节点

respawn hacluster /usr/lib64/heartbeat/ipfail #使用这个脚本去侦听对方是否还活着（使用的是ICMP报文检测）

[root@heartbeat02 ha.d]# egrep -v "#|^$" ha.cf

debugfile /var/log/ha-debug

logfile /var/log/ha-log

logfacility local1

keepalive 2

deadtime 30

warntime 10

initdead 60

ucast eth1 172.16.49.133

auto_failback on

node heartbeat01.contoso.com

node heartbeat02.contoso.com

ping 172.16.49.1

respawn hacluster /usr/lib64/heartbeat/ipfail

# 两个节点的差别只有单播的对端IP不一样，其他都一样

4）配置haresources

echo ‘heartbeat01.contoso.com IPaddr::172.16.49.100/24/eth1‘ >>/etc/ha.d/haresources

[root@heartbeat01 ha.d]# egrep -v "#|^$" haresources

heartbeat01.contoso.com IPaddr::172.16.49.100/24/eth1

[root@heartbeat02 ha.d]# egrep -v "#|^$" haresources

heartbeat01.contoso.com IPaddr::172.16.49.100/24/eth1

# 两个节点的配置一致

四、启动heartbeat并测试

/etc/init.d/heartbeat start  #分别在heartbeat01和heartbeat02上执行

到两个节点上分别查看VIP：

[root@heartbeat01 ha.d]# ip addr |grep 172.16.49

inet 172.16.49.133/24 brd 172.16.49.255 scope global eth1

inet 172.16.49.100/24 brd 172.16.49.255 scope global secondary eth1

[root@heartbeat02 ha.d]# ip addr |grep 172.16.49

inet 172.16.49.134/24 brd 172.16.49.255 scope global eth1

然后，将heartbeat01上的heartbeat服务关闭，再进行查看：

[root@heartbeat01 ha.d]# /etc/init.d/heartbeat stop

Stopping High-Availability services: Done.

[root@heartbeat01 ha.d]# ip addr |grep 172.16.49

inet 172.16.49.133/24 brd 172.16.49.255 scope global eth1

[root@heartbeat02 ha.d]# ip addr |grep 172.16.49

inet 172.16.49.134/24 brd 172.16.49.255 scope global eth1

inet 172.16.49.100/24 brd 172.16.49.255 scope global secondary eth1

可以看到，VIP已经从heartbeat01上转移到heartbeat02上了。

技术分享

在VIP切换过程中，从另一台主机ping VIP地址，间断时间非常短暂。

五、检查日志

/var/log/ha-log
