lvs-dr 模式-piranha

系统: redhat 6.5 mini

1、  在各个机器上配置ip地址，机器名，关闭selinux,同步时间

[root@lvs01 ~]# hostname

lvs01

[root@lvs01 ~]# getenforce

Disabled

[root@lvs02 ~]# hostname

lvs02

[root@lvs02 ~]# getenforce

Disabled

[root@rs01 ~]# hostname

rs01

[root@rs01 ~]# getenforce

Disabled

[root@rs02 ~]# hostname

rs02

[root@rs02 ~]# getenforce

Disabled

[root@lvs01 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

[root@lvs01 yum.repos.d]# ntpdate 0.rhel.pool.ntp.org

[root@lvs02 yum.repos.d]# ntpdate 0.rhel.pool.ntp.org

[root@rs01 yum.repos.d]# ntpdate 0.rhel.pool.ntp.org

[root@rs02 yum.repos.d]# ntpdate 0.rhel.pool.ntp.org

2、  在各个机器关闭防火墙，配置yum源

[root@lvs01 yum.repos.d]# service iptables stop

[root@lvs01 yum.repos.d]# chkconfig iptables off

[root@lvs02 ~]# service iptables stop

[root@lvs02 ~]# chkconfig iptables off

[root@rs01 ~]# service iptables stop

[root@rs01 ~]# chkconfig iptables off

[root@rs02 ~]# service iptables stop

[root@rs02 ~]# chkconfig iptables off

[root@lvs01 yum.repos.d]# service iptables stop

[root@lvs01 yum.repos.d]# chkconfig iptables off

[root@lvs01 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

[root@lvs01 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

[root@rs01 ~]#ip addr add 192.168.20.254/24 dev eth0

[root@rs01 ~]# echo "ip addr add 192.168.20.254/24 dev eth0">>/etc/rc.d/rc.local

[root@rs01 ~]# arptables -A IN -d 192.168.20.254 -j DROP

[root@rs01 ~]# arptables -A OUT -s 192.168.20.254 -j mangle --mangle-ip-s 192.168.20.100

[root@rs01 ~]# service arptables_jf save

将当前规则保存到 /etc/sysconfig/arptables：                [确定]

[root@rs01 ~]# chkconfig arptables_jf on

[root@rs01 ~]# yum install -y httpd

[root@rs01 ~]# echo "rs01">/var/www/html/index.html

[root@rs01 ~]# service httpd restart

[root@rs01 ~]# chkconfig httpd on

[root@rs02 ~]# arptables -A IN -d 192.168.20.254 -j DROP

[root@rs02 ~]# arptables -A OUT -s 192.168.20.254 -j mangle --mangle-ip-s 192.168.20.100

[root@rs02 ~]# service arptables_jf save

将当前规则保存到 /etc/sysconfig/arptables：                [确定]

[root@rs02 ~]# chkconfig arptables_jf on

[root@rs02 ~]#ip addr add 192.168.20.254/24 dev eth0

[root@rs02 ~]# echo "ip addr add 192.168.20.254/24 dev eth0">>/etc/rc.d/rc.local

[root@rs02 ~]# yum install -y httpd

[root@rs02 ~]# echo "rs02">/var/www/html/index.html

[root@rs02 ~]# service httpd restart

[root@rs02 ~]# 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

[root@lvs01 yum.repos.d]# yum groupinstall "Load Balancer"

[root@lvs02 yum.repos.d]# yum groupinstall "Load Balancer"

 [root@lvs01 yum.repos.d]# piranha-passwd

New Password:

Verify:

Adding password for user piranha

[root@lvs01 yum.repos.d]# /etc/init.d/piranha-gui start

[root@lvs01 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

[root@lvs01 ~]# scp /etc/sysconfig/ha/lvs.cf lvs02:/etc/sysconfig/ha/lvs.cf

root@lvs02‘s password:

lvs.cf                              100%  865     0.8KB/s   00:00

[root@lvs01 ~]# /etc/init.d/pulse restart

Shutting down pulse:                                       [失败]

Starting pulse:                                            [确定]

[root@lvs01 ~]# chkconfig pulse on

[root@lvs02 ~]# /etc/init.d/pulse restart

Shutting down pulse:                                       [失败]

Starting pulse:                                            [确定]

[root@lvs02 ~]# 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
