在安裝配置LVS時需要先進行安裝ipvsadm,安裝時報錯如下
[root@lvsslave ipvsadm]# cd ipvsadm-1.26

以上錯誤百度有許多等同案例，初步判斷是缺少依賴包導致make失敗，首先檢查兩個包是否存在,其次要覈對報錯信息是否與缺少這兩個包的報錯類似，64bit的kernel-headers，popt-static的兩個包
[root@lvsmaster ipvsadm-1.26]# rpm -qa | grep kernel-headers
kernel-headers-2.6.32-573.el6.x86_64
[root@lvsmaster ipvsadm-1.26]# rpm -qa | grep popt-static
經過查詢，本系統缺少popt-static包
去官網進行wget
[root@lvsmaster ~]# wget http://mirror.centos.org/centos/6/os/x86_64/Packages/popt-static-1.13-7.el6.x86_64.rpm
--2016-05-19 00:30:18-- http://mirror.centos.org/centos/6/os/x86_64/Packages/popt-static-1.13-7.el6.x86_64.rpm

安裝完成後，再次進行make,這次沒有ERROR返回，表明ipvsadm已經安裝成功了
