1、 在各个机器上配置ip地址，机器名，关闭selinux,同步时间
[[email protected] ~]# hostname
lvs01
[[email protected] ~]# getenforce
Disabled
[[email protected] ~]# hostname
lvs02
[[email protected] ~]# getenforce
Disabled
[[email protected] ~]# hostname
rs01
[[email protected] ~]# getenforce
Disabled
[[email protected] ~]# hostname
rs02
[[email protected] ~]# getenforce
Disabled
[[email protected] yum.repos.d]# cat /etc/hosts
192.168.20.10 lvs01
192.168.20.20 lvs02
192.168.20.100 rs01
192.168.20.200 rs02
[[email protected] yum.repos.d]# ntpdate 0.rhel.pool.ntp.org
[[email protected] yum.repos.d]# ntpdate 0.rhel.pool.ntp.org
[[email protected] yum.repos.d]# ntpdate 0.rhel.pool.ntp.org
[[email protected] yum.repos.d]# ntpdate 0.rhel.pool.ntp.org
2、 在各个机器关闭防火墙，配置yum源
[[email protected] yum.repos.d]# service iptables stop
[[email protected] yum.repos.d]# chkconfig iptables off
[[email protected] ~]# service iptables stop
[[email protected] ~]# chkconfig iptables off
[[email protected] ~]# service iptables stop
[[email protected] ~]# chkconfig iptables off
[[email protected] ~]# service iptables stop
[[email protected] ~]# chkconfig iptables off
[[email protected] yum.repos.d]# service iptables stop
[[email protected] yum.repos.d]# chkconfig iptables off
[[email protected] yum.repos.d]# cat rhel-source.repo
[base]
name=base
baseurl=file:///mnt
enabled=1
gpgcheck=0
[LB]
name=LB
baseurl=file:///mnt/LoadBalancer
enabled=1
gpgcheck=0
[HA]
name=HA
baseurl=file:///mnt/HighAvailability
enabled=1
gpgcheck=0
[RS]
name=RS
baseurl=file:///mnt/ResilientStorage
enabled=1
gpgcheck=0
[[email protected] yum.repos.d]# scp rhel-source.repo lvs02:/etc/yum.repos.d/rhel-source.repo
3、 在rs01.rs02上部署web服务，设置arptables，添加vip
[[email protected] ~]#ip addr add 192.168.20.254/24 dev eth0
[[email protected] ~]# echo "ip addr add 192.168.20.254/24 dev eth0">>/etc/rc.d/rc.local
[[email protected] ~]# arptables -A IN -d 192.168.20.254 -j DROP
[[email protected] ~]# arptables -A OUT -s 192.168.20.254 -j mangle --mangle-ip-s 192.168.20.100
[[email protected] ~]# service arptables_jf save
将当前规则保存到 /etc/sysconfig/arptables： [确定]
[[email protected] ~]# chkconfig arptables_jf on
[[email protected] ~]# yum install -y httpd
[[email protected] ~]# echo "rs01">/var/www/html/index.html
[[email protected] ~]# service httpd restart
[[email protected] ~]# chkconfig httpd on
[[email protected] ~]# arptables -A IN -d 192.168.20.254 -j DROP
[[email protected] ~]# arptables -A OUT -s 192.168.20.254 -j mangle --mangle-ip-s 192.168.20.100
[[email protected] ~]# service arptables_jf save
将当前规则保存到 /etc/sysconfig/arptables： [确定]
[[email protected] ~]# chkconfig arptables_jf on
[[email protected] ~]#ip addr add 192.168.20.254/24 dev eth0
[[email protected] ~]# echo "ip addr add 192.168.20.254/24 dev eth0">>/etc/rc.d/rc.local
[[email protected] ~]# yum install -y httpd
[[email protected] ~]# echo "rs02">/var/www/html/index.html
[[email protected] ~]# service httpd restart
[[email protected] ~]# chkconfig httpd on
4、 在lvs01,lvs02安装LB,在lvs01上配置lvs集群登录用户和密码
[[email protected] yum.repos.d]# yum groupinstall "Load Balancer"
[[email protected] yum.repos.d]# yum groupinstall "Load Balancer"
[[email protected] yum.repos.d]# piranha-passwd
New Password:
Verify:
Adding password for user piranha
[[email protected] yum.repos.d]# /etc/init.d/piranha-gui start
[[email protected] yum.repos.d]# chkconfig piranha-gui on
5、通过浏览器配置lvs集群
5.1 在浏览器输入http://192.168.20.10:3636 输入用户名和密码
5.2 配置lvs01,ip地址，选direct
5.3 配置lvs02
5.4 配置对外服务和真实服务器
5.5 将在lvs01 上的配置文件复制到lvs02 上，在lvs01,lvs02 上启动负载均衡的监控进程
[[email protected] ~]# scp /etc/sysconfig/ha/lvs.cf lvs02:/etc/sysconfig/ha/lvs.cf
[email protected]‘s password:
lvs.cf 100% 865 0.8KB/s 00:00
[[email protected] ~]# /etc/init.d/pulse restart
Shutting down pulse: [失败]
Starting pulse: [确定]
[[email protected] ~]# chkconfig pulse on
[[email protected] ~]# /etc/init.d/pulse restart
Shutting down pulse: [失败]
Starting pulse: [确定]
[[email protected] ~]# chkconfig pulse on
5.6 lvs 正常运行的状态
1、 测试
3.1 正常访问
3.2 lvs01 宕机了，可以正常访问
3.3 rs01 宕机了，也可正常访问
