CentOS 6.5上部署Heartbeat

g87616758

　　环境说明：

主机名	角色	IP地址	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 "#|^$" ha.cf
　　debugfile /var/log/ha-debug  #设置debug文件位置
　　logfile/var/log/ha-log  #设置日志文件位置
　　logfacilitylocal1  #设置记录日志的设备
　　keepalive 2  #设置发送心跳报文的时间间隔
　　deadtime 30  #设置确认对端死亡的时间间隔
　　warntime 10  #设置发出最后的心跳警告报文的间隔
　　initdead 60  #设置初始化时间
　　ucast eth1 172.16.49.134  #设定侦听的心跳线的接口和对应的对端接口的IP地址
　　auto_failback on  #启用自动恢复模式，当拥有该资源的属主恢复之后，属主将回收该资源
　　nodeheartbeat01.contoso.com  #指定节点1，节点的名称一定要和uname -n的结果一致
　　nodeheartbeat02.contoso.com  #指定节点2
　　ping 172.16.49.1  #指定第三方仲裁节点
　　respawn hacluster /usr/lib64/heartbeat/ipfail  #使用这个脚本去侦听对方是否还活着（使用的是ICMP报文检测）
　　[root@heartbeat02 ha.d]# egrep -v "#|^$" ha.cf
　　debugfile /var/log/ha-debug
　　logfile/var/log/ha-log
　　logfacilitylocal1
　　keepalive 2
　　deadtime 30
　　warntime 10
　　initdead 60
　　ucast eth1 172.16.49.133
　　auto_failback on
　　nodeheartbeat01.contoso.com
　　nodeheartbeat02.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。

　　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
