heartbeat 安装
- rpm -ivh heartbeat-pils-2.1.3-3.el5.centos.x86_64.rpm
- rpm -ivh heartbeat-stonith-2.1.3-3.el5.centos.x86_64.rpm
- rpm -ivh PyXML-0.8.4-4.x86_64.rpm
- rpm -ivh heartbeat-2.1.3-3.el5.centos.x86_6
4.rpm
注:若heartbeat一次未安装好,再装一次
- rpm -q heartbeat -d #查看安装路径
- echo "service heartbeat start" >> /etc/rc.local
配置heartbeat
- cd /usr/share/doc/heartbeat-2.1.3/
- cp authkeys ha.cf haresources /etc/ha.d/
- cd /etc/ha.d
- vi authkeys
#去掉注释 设置校验模式
- auth 1
- 1 crc
- #2 sha1 HI!
- #3 md5 Hello!
- echo "10.0.0.108 HA1" >>/etc/hosts
- echo "10.0.0.109 HA2" >>/etc/hosts
- vi haresources
- #添加:(约44行下面)
- HA1 10.0.0.100 vip.sh
- vi ha.cf
- #去掉注释(约95行)
- bcast eth0
- #去掉注释并修改(约125行)
- ucast eth0 10.0.0.109
- #去掉注释并修改(约215、216行)
- node HA1
- node HA2
- chmod 600 authkeys
- vi /etc/init.d/vip.sh
- #/sbin/bash!
- ifconfig eth0:0 10.0.0.100 broadcast 10.0.0.100 netmask 255.255.255.255 up
- route add -host 10.0.0.100 dev eth0:0
- #setup ipvs
- ipvsadm -C
- ipvsadm -A -t 10.0.0.100:80 -s rr
- ipvsadm -a -t 10.0.0.100:80 -r 10.0.0.110 -g
- ipvsadm -a -t 10.0.0.100:80 -r 10.0.0.111 -g
- ipvsadm
HA2的配置和HA1一样,可以直接上传HA1的authkeys ha.cf haresources三个文件
- sftp 10.0.0.108
- cd /etc/ha.d
- get authkeys ha.cf haresources
- quit
修改HA2中ha.cf里(约125行)为:
- ucast eth0 10.0.0.108
把vip.sh放到LVS服务器
- vi /etc/init.d/vip.sh //放到这里开机自启动
- chmod 755 /etc/init.d/vip.sh
- /etc/init.d/vip.sh
- echo "service heartbeat start" >> /etc/rc.local
lvs.sh
- #/sbin/bash!
- ifconfig lo:0 10.0.0.100 broadcast 10.0.0.100 netmask 255.255.255.255 up
- route add -host 10.0.0.100 dev lo:0
- echo "1">/proc/sys/net/ipv4/conf/lo/arp_ignore
- echo "2">/proc/sys/net/ipv4/conf/lo/arp_announce
- echo "1">/proc/sys/net/ipv4/conf/all/arp_ignore
- echo "2">/proc/sys/net/ipv4/conf/all/arp_announce
- sysctl -p
web1 web2安装WEB服务
安装过程略
注:
把lvs.sh放到WEB服务器
- #vi /etc/init.d/lvs.sh #放到这里开机自启动
- #chmod 755 /etc/init.d/lvs.sh
- #/etc/init.d/lvs.sh
得出结论:
不断刷新10.0.0.100,会轮流显示web1和web2页面
