软件:heartbeat
准备两台机器,均是64位系统
给两台主从机器分别设置新的hostname:master 和 slave
确保两台机器的selinux和iptables都关掉
编辑主和从的/etc/hosts:
192.168.237.133 master
192.168.237.137 slave
安装扩展源:rpm -ivh epel-release-6-8_64.noarch.rpm
yum安装heartbeat: yum install -y heartbeat
yum安装libnet: yum install -y libnet
拷贝配置文件样例:
[root@master ~]# cd /usr/share/doc/heartbeat-3.0.4
[root@master heartbeat-3.0.4]# ls
apphbd.cf authkeys AUTHORS ChangeLog COPYING COPYING.LGPL ha.cf haresources README
[root@master heartbeat-3.0.4]# cp authkeys ha.cf haresources /etc/ha.d/
[root@master heartbeat-3.0.4]# cd /etc/ha.d
[root@master ha.d]# ls
authkeys ha.cf harc haresources rc.d README.config resource.d shellfuncs
编辑authkeys,让两台机器在加密的情况下进行通信,确认对方是否存活:
vim authkeys
安全级别有小到大:1<3<2
auth 3
#1 crc
#2 sha1 HI!
3 md5 Hello!
修改权限:chmod 600 authkeys
编辑haresources:修改主的名字,流动IP和启动的服务资源
首先给网卡eth0添加一个虚拟ip:
[root@master ha.d]# cd /etc/sysconfig/network-scripts/
[root@master network-scripts]# cp ifcfg-eth0 ifcfg-eth0:1
[root@master network-scripts]# vim ifcfg-eth0:1
DEVICE=eth0:1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.237.109
NETMASK=255.255.255.0
重启网卡:[root@master network-scripts]# /etc/init.d/network restart
vim haresources
master 192.168.237.109/24/eth0:1 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 192.168.237.137
auto_failback on
node master
node slave
ping 192.168.237.1
respawn hacluster /usr/lib64/heartbeat/ipfail
把配置文件拷贝到slave上去:
[root@master ha.d]# rsync -av authkeys ha.cf haresources slave:/etc/ha.d/
在slave上只修改ha.cf
[root@slave ha.d]# vim ha.cf
ucast eth0 192.168.237.133
两台机器上准备好启动nginx服务
启动heartbeat: 先启动主,再启动从
