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

    [root@node2 ha.d]# 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

    [root@node2 ha.d]# ntpdate s1a.time.edu.cn

    [root@node2 ha.d]# service ntpd start


    2、节点之间名称相互通信

    [root@node2 ha.d]# 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

    [root@node1 ha.d]# hostname node1.hailang.com

    [root@node1 ha.d]# uname -n


    3、SSH互相认证

    [root@node1 ha.d]# ssh-keygen -t rsa 

    [root@node1 ha.d]# ssh-copy-id ~/.ssh/id_isa.pub 192.168.239.134

    [root@node1 ha.d]# ssh node2.hailang.com


    4、关闭防火墙和SELINUX

    [root@node1 ha.d]# service iptables stop

    [root@node1 ha.d]# setenforce 0

    

    5、配置yum源

    [root@node1 ha.d]# vim /etc/yum.repos.d/epel.repo

    

    [epel]

    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)

    [root@node1 ha.d]# yum -y install httpd

    [root@node1 ha.d]# vim /var/www/html/index.html

    node1


四、安装并配置herartbeat v1


    1、安装

    [root@node1 ~]# yum install perl-TimeDate net-snmp-libs libnet PyXML

    [root@node1 ~]# rpm -ivh heartbeat-pils-2.1.4-12.el6.x86_64.rpm heartbeat-2.1.4-12.el6.x86_64.rpm  heartbeat-stonith-2.1.4-12.el6.x86_64.rpm

    

    2、配置(2个节点的配置文件都一样）      

        [root@node1 ~]# cp /usr/share/doc/heartbeat-2.1.4/{ha.cf,authkeys,haresources} /etc/ha.d/


        1）ha.cf

        [root@node1 ~]# 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

        [root@node1 ~]# vim /etc/ha.d/authkeys

        auth 1

        1 crc


        3)haresources

        node1.hailang.com  IPaddr::192.168.239.200/24/eth0 httpd


        3、启动

        [root@node1 ha.d]# service heartbeat start

        

        4、验证

        1）在2台服务器启动heartbeat服务

            [root@node1 ha.d]# ss -tulnp|grep 80

            [root@node1 ha.d]# ifconfig 

        

        2）访问主页显示node1

        http://192.168.239.200


        3）停掉node1

        [root@node1 ha.d]# service heartbeat stop


        4）再次访问主页显示node2

        http://192.168.239.200
