LVS DR模式

1.首先打开三台机器，server1,server2,server3 2.分别对yum源进行修改

vim /etc/yum.repos.d/rhel-source.repo [rhel-source] name=Red Hat Enterprise Linux $releasever - $basearch - Source baseurl=http://172.25.77.250/rhel6.5 enabled=1 gpgcheck=0 [HighAvailability] name=HighAvailability baseurl=http://172.25.77.250/rhel6.5/HighAvailability gpgcheck=0 [LoadBalancer] name=LoadBalancer baseurl=http://172.25.77.250/rhel6.5/LoadBalancer gpgcheck=0 [ResilientStorage] name=ResilientStorage baseurl=http://172.25.77.250/rhel6.5/ResilientStorage gpgcheck=0 [ScalableFileSystem] name=ScalableFileSystem baseurl=http://172.25.77.250/rhel6.5/ScalableFileSystem gpgcheck=0

3.在server1上安装ipvsadm

yum install ipvsadm -y

添加ip地址 添加策略

4.在server2,server3上启动httpd服务,并添加ip addr

5.测试结果如图 6.如果此时其中某个机器的httpd服务关闭，就不能访问该机器。此时就需要ldirectord来自移除失效节点。

在server1上安装ldirectord. yum install ldirectord-3.9.5-3.1.x86_64.rpm -y

vim /etc/ha.d/ldirectord.cf

7.关闭server2的httpd服务后进行测试

开启server2的httpd服务后测试
