heartbeat v1
heartbeat v1一、实验环境介绍
硬件：lenovo T410S
软件：VMWARE workstation
SO: Centos 6.6
二、网络拓扑
网卡类型：NAT
RIP: 192.168.239.133 node1.hailang.com
192.168.239.134 node2.hailang.com
VIP: 192.168.239.200
三、实验环境准备
1、配置NTP服务器确保时间同步
# vim /etc/ntp.conf
添加如下
restrict 192.168.239.0 mask 255.255.255.0 nomodify #允许哪些个网段的主机过来同步
注释下面的时间服务器
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server server s1a.time.edu.cn #去该NTP服务器同步时间
# ntpdate s1a.time.edu.cn
# service ntpd start
2、节点之间名称相互通信
# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.239.133 node1.hailang.com node1
192.168.239.134 node2.hailang.com node2
# hostname node1.hailang.com
# uname -n
3、SSH互相认证
# ssh-keygen -t rsa
# ssh-copy-id ~/.ssh/id_isa.pub 192.168.239.134
# ssh node2.hailang.com
4、关闭防火墙和SELINUX
# service iptables stop
# setenforce 0
5、配置yum源
# vim /etc/yum.repos.d/epel.repo
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://mirrors.aliyun.com/epel/6/$basearch
http://mirrors.aliyuncs.com/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
6、httpd（node1提供页面的内容为node1，node2提供页面的内容为node2)
# yum -y install httpd
# vim /var/www/html/index.html
node1
四、安装并配置herartbeat v1
1、安装
# yum install perl-TimeDate net-snmp-libs libnet PyXML
# rpm -ivh heartbeat-pils-2.1.4-12.el6.x86_64.rpm heartbeat-2.1.4-12.el6.x86_64.rpmheartbeat-stonith-2.1.4-12.el6.x86_64.rpm
2、配置(2个节点的配置文件都一样）
# cp /usr/share/doc/heartbeat-2.1.4/{ha.cf,authkeys,haresources} /etc/ha.d/
1）ha.cf
# vim /etc/ha.d/ha.cf
logfile /var/log/ha-log
keepalive 2
deadtime 30
warntime 10
initdead 120
udpport 694
mcast eth0 225.0.0.1 694 1 0
auto_failback on
node node1.hailang.com
node node2.hailang.com
ping 192.168.239.1
2)authkeys
# vim /etc/ha.d/authkeys
auth 1
1 crc
3)haresources
node1.hailang.comIPaddr::192.168.239.200/24/eth0 httpd
3、启动
# service heartbeat start
4、验证
1）在2台服务器启动heartbeat服务
# ss -tulnp|grep 80
# ifconfig
2）访问主页显示node1
http://192.168.239.200
3）停掉node1
# service heartbeat stop
4）再次访问主页显示node2
http://192.168.239.200
