heartbeat主机配置

第一步关闭防火墙及selinux

iptables -F

service iptables save

vim /etc/selinux/config

reboot

添加host文件内容

vim /etc/hosts

192.168.238.132 linux-server

192.168.238.133 linux-client

下载扩展源安装包

wget www.lishiming.net/data/p_w_upload/forum/epel-release-6-8_64.noarch.rpm

安装扩展源安装包

rpm -ivh epel-release-6-8_64.noarch.rpm

yum安装heartbeat及libnet

yum install -y heartbeat libnet

切换到安装目录拷贝文件到/etc/ha.d下

cd /usr/share/doc/heartbeat-3.0.4/

cp authkeys ha.cf haresources /etc/ha.d/

切换目录到/etc/ha.d编辑配置

cd /etc/ha.d/

vim authkeys

auth 3

3 md5 Hello!

并且赋予600读写权限给root

chmod 600 authkeys

vim haresources

linux-server  192.168.238.100/24/eth0:0 nginx

vim ha.cf

debugfile /var/log/ha-debug

logfile /var/log/ha-log

logfacility   local0

keepalive 2

deadtime 30

warntime  10

initdead 60

udpport  694

ucast eth0 192.168.238.133

auto_failback on

node    linux-server

node    linux-client

ping 192.168.238.1

respawn hacluster /usr/lib64/heartbeat/ipfail

拷贝编辑的此三个文件到第二台服务器的/etc/ha.d目录下

scp authkeys ha.cf haresources linux-client:/etc/ha.d/

安装nginx服务

yum install -y nginx

启动heartbeat服务

/etc/init.d/heartbeat start

heartbeat备机配置

关闭防火墙及selinux

iptables -F

service iptables save

vim /etc/selinux/config

reboot

配置host文件

vim /etc/hosts

192.168.238.132 linux-server

192.168.238.133 linux-client

下载epel扩展源

wget www.lishiming.net/data/p_w_upload/forum/epel-release-6-8_64.noarch.rpm

安装epel扩展源

rpm -ivh epel-release-6-8_64.noarch.rpm

yum install -y heartbeat libnet

切换到/etc/ha.d目录下编辑ha.cf文件，authkeys和haresources文件不用更改

cd /etc/ha.d/

vim ha.cf

debugfile /var/log/ha-debug

logfile /var/log/ha-log

logfacility   local0

keepalive 2

deadtime 30

warntime  10

initdead 60

udpport  694

ucast eth0 192.168.238.133

auto_failback on

node    linux-server

node    linux-client

ping 192.168.238.1

respawn hacluster /usr/lib64/heartbeat/ipfail

yum install -y nginx

/etc/init.d/heartbeat start

环境测试

echo "this is heartbeat server11111111111111111111111111" > /usr/share/nginx/html/index.html   主机

echo "this is heartbeat server22222222222222222222222222" > /usr/share/nginx/html/index.html   备机

客户端浏览器访问192.168.238.100

出现“this is heartbeat server11111111111111111111111111" 正常

在服务器主机上添加一条防火墙规则，拒绝ping

iptables -A INPUT -p icmp -j DROP

客户端浏览器访问192.168.238.100

出现“this is heartbeat server22222222222222222222222222" 正常

删除刚才添加的防火墙规则

iptables -D INPUT -p icmp -j DROP

客户端浏览器访问192.168.238.100

出现“this is heartbeat server11111111111111111111111111" 正常
