CentOS 6.5上部署Heartbeat

前端之家收集整理的这篇文章主要介绍了CentOS 6.5上部署Heartbeat前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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/iptablesstop
chkconfigiptablesoff
sed-i'/^SELINUX/s/enforcing/disabled/'/etc/selinux/config
setenforce0

#设置时间同步
crontab-e#添加计划任务
0****/usr/sbin/ntpdate210.72.145.4464.147.116.229time.nist.gov
:wq
或者
echo'0****/usr/sbin/ntpdate210.72.145.4464.147.116.229time.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/ntpdate210.72.145.4464.147.116.229time.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
grepHOSTNAME/etc/sysconfig/network
hostnameheartbeat01.contoso.com
或者
sed-i'/^HOSTNAME/d'/etc/sysconfig/network
echo'HOSTNAME=heartbeat01.contoso.com'>>/etc/sysconfig/network
grepHOSTNAME/etc/sysconfig/network
hostnameheartbeat01.contoso.com

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

#添加一条主机路由
/sbin/routeadd-host172.16.49.134deveth1#在heartbeat01上配置
echo'/sbin/routeadd-host172.16.49.134deveth1'>>/etc/rc.local#在heartbeat01上配置
/sbin/routeadd-host172.16.49.133deveth1#在heartbeat02上配置
echo'/sbin/routeadd-host172.16.49.133deveth1'>>/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-ivhhttp://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum-yinstallheartbeat*

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/heartbeatstart#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

/var/log/ha-log
