LVS在企业网中的应用(5)

背景：

LVS在企业网中的应用

这里需要配置yum

[root@localhost ~]# mkdir /mnt/cdrom

[root@localhost ~]# mount /dev/cdrom /mnt/cdrom/

[root@localhost ~]# vim /etc/yum.repos.d/rhel-debuginfo.repo

[rhel-server]
2 name=Red Hat Enterprise Linux server
3 baseurl=file:///mnt/cdrom/Server
4 enabled=1
5 gpgcheck=1
6 gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-RedHat-release
7 [rhel-cluster]
8 name=Red Hat Enterprise Linux cluster
9 baseurl=file:///mnt/cdrom/Cluster
10 enabled=1
11 gpgcheck=1
12 gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release
13 [rhel-vt]
14 name=Red Hat Enterprise Linux vt
15 baseurl=file:///mnt/cdrom/VT
16 enabled=1
17 gpgcheck=1
18 gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release
19 [rhel-clusterstorage]
20 name=Red Hat Enterprise Linux clusterstorage
21 baseurl=file:///mnt/cdrom/ClusterStorage
22 enabled=1
23 gpgcheck=1
24 gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release

安装ipvsadm

[root@localhost ~]# yum install ipvsadm –y

添加规则

访问192.168.145.101的80端口时采用rr调度算法，并且发送给Web服务器群集节点

[root@localhost ~]# ipvsadm -A -t 192.168.145.101:80 -s rr
[root@localhost ~]# ipvsadm -a -t 192.168.145.101:80 -r 192.168.145.200 –g  //-g表示模型为DR
[root@localhost ~]# ipvsadm -a -t 192.168.145.101:80 -r 192.168.145.201 -g

[root@localhost ~]# service ipvsadm save //保存规则

[root@localhost ~]# service ipvsadm start //启动服务

添加一个设备，这里命名为eth0:0 ,ip地址设为192.168.145.101 子网掩码设为255.255.255.0

[root@localhost ~]# ifconfig
