############################### ##########Start deployment

centos 5.8 directly yum install heartbeat -y twice That’s it (remember)

If it is centos 6.5, you need yum install heartbeat* -y< /p>

The following is installed under centos 6.5

1. First download and install the epel package

wget http ://mirrors.opencas.cn/epel/6/i386/epel-release-6-8.noarch.rpmwget http://mirrors.opencas.cn/epel/6/x86_64/epel-release-6-8. noarch.rpm

mkdir -p /home/lvnian/tools && cd /home/lvnian/tools p>

#Download and install the epel package

 mkdir -p /home/lvnian/tools&& cd /home/lvnian/tools wget http://mirrors.opencas.cn /epel/6/x86_64/epel-release-6-8.noarch.rpmrpm -ivh epel-release-6-8.noarch.rpm

2. Install heartbeat , The following is deployed in the centos version system, all use yum install heartbeat* -y. If it is centos5.8, you need yum twice

yum install heartbeat*-y

3. Copy ha configuration files, resource files and authorization files to /etc/ha.d/.

By default, there is no configuration file in /etc/ha.d/, and the configuration files are all in /usr /share/doc/heartbeat-3.0.4/ directory

ll /usr/share/doc/heartbeat-3.0.4/cd /usr/share/doc/heartbeat-3.0.4/cp ha.cf haresources authkeys /etc/ha.d/4. Start configuration

cd/etc/ha.dmvha.cfha.bakmvauthkeysauthkeys.bakmvharesourcesharesources.bak

Note: The following three files, ha.cf, authkeys, and haresources, are both active and standby The same

########Configuration ha.cfcat>/etc/ha.d/ha.cf</etc/ha.d/ authkeys< /etc/ha.d/haresources<

 < p>


 #Start the heartbeat service


/etc/init.d/heartbeat start/etc/init.d/heartbeat stop/etc/init.d /heartbeat Restart




Use ip add to view vip


View cat /var/log/ha-log log file

HB1 is the host name, which means that the initial state will bind IP 10.0.0.103 to HB1. IPaddr is a script in the /etc/ha.d/resource.d directory, and the following IP 10.0.0.103 and eth0 are the parameters of the script. Its function is to add an auxiliary IP on the specified network card. 10.0.0.103/24/eth0 is the VIP for external services of the cluster, which is initially started on HB1, #24 is the subnet mask, and eth0 is the actual physical network card bound to ip, which provides the communication interface for external services for heartbaeat
