CenTos6.8 Installation Heartbeat

I combine the online tutorial, I slowly learn to write, write very simple, do not spray!

Environment:

System: Centos6.8 (2.6.32-642.el6.x86_x64)

Software: heartbeat-3.0.4-2.el6.x86_x64

Topology:

First: Turn off firewall time synchronization and so on, you can see the previous article.

HA01 Configuration

Modify hostname,

# hostname HA01 (the name can be casual, but not the number)

# echo ' 192.168.20.1 ha01 ' >>/etc/hosts (parsing)

#echo '/sbin/route add-host 192.168.30.2 dev eth2 ' >>/etc/rc.local (Heartbeat routing trend)

#route-N (see if correct)

After the modification, if it does not take effect can be restarted, ping 192.168.20.1 can get ha01 return value on the line.

The following Yum has been installed.

CentOS may not have a heartbeat Yum installation source and need to install epel-release.

# yum Install Epel-release-y

# yum Install heartbeat*-y

After the installation, all the documents are under/usr/share/doc/heartbeat-3.0.4, the main files are:

HA.CF Basic Configuration file

Authkeys Key Configuration

Haresources IP Address and script configuration file

After the first two configurations are almost unchanged, haresources may change frequently because the nodes are incremented in this file.

Copy three files to the/etc/ha.d/directory, but many of the online is handwritten a simple, so no copy, but handwritten three configuration files.

# cd/etc/ha.d/

This directory was originally HARC RC.D Readme.config resource.d Shellfuncs

The HA02 server configuration is almost constant:

(just modify the following two points)

#hostname HA02

#echo '/sbin/route add-host 192.168.30.1 dev eth2 ' >>/etc/rc.local (Heartbeat routing trend)

##########################################################

#启动服务:

/etc/init.d/heartbeat start

Prompt two lines, last line tip: Done

Then enter:

Ha01#ip A

You can see that there are two IP on the eth0, if the virtual machine has automatic acquisition, and the network will have three addresses.

Then simulate the down machine to see if it can take over.

Stop HA01

At present: Next time, if there are omissions or errors, I hope to correct.
