在安装配置LVS时需要先进行安装ipvsadm,安装时报错如下

以上错误百度有许多等同案例,初步判断是缺少依赖包导致make失败,首先检查两个包是否存在,其次要核对报错信息是否与缺少这两个包的报错类似,64bit的kernel-headers,popt-static的两个包
[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
经过查询,本系统缺少popt-static包
去官网进行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

安装完成后,再次进行make,这次没有ERROR返回,表明ipvsadm已经安装成功了
