ipvsadm+keepalived安装错误解决

1、环境：
 rhel 6.0+ipvsadm-1.2.6+keepalived-1.2.5
2、安装
 
实现LVS/DR最重要的两个东西是ipvs内核模块和ipvsadm工具包，现在的系统已经包含ip_vs模块 

1）检查内核模块，看一下ip_vs 是否被加载 

# lsmod |grep ip_vs 

ip_vs    35009    0 

如果没有显示，则说明没有加载，执行命令 modprobe ip_vs 就可以把ip_vs模块加载到内核 

#modprobe ip_vs   然后再查看就有了。
2）安装ipvsadm 
 
查看内核版本   #uname -r  
  2.6.32-71.el6.x86_64

先把目录/usr/src/kernels/2.6.32-71.el6.x86_64链接为/usr/src/linux，命令如下 

ln –s /usr/src/2.6.32-71.el6.x86_64    /usr/src/linux 

解压ipvsadm-1.24.tar.gz,执行"make;但是报错了，类似的错误信息大概如下
 
make -C libipvs

解决：yum install libnl* libpopt*

再次make，还是有报错
类似如  /usr/src/ipvsadm-1.26/ipvsadm.c:667: undefined reference to `poptStrerror'
/usr/src/ipvsadm-1.26/ipvsadm.c:667: undefined reference to `poptBadOption'

/usr/src/ipvsadm-1.26/ipvsadm.c:693: undefined reference to `poptFreeContext'
collect2: ld returned 1 exit status
make: *** [ipvsadm] Error 1
 
解决：yum install    popt-static （ftp://ftp.muug.mb.ca/mirror/centos/6.3/os/x86_64/packages/popt-static-1.13-7.el6.x86_64.rpm）
再次make通过，然后make instll  完成安装
 
3）安装keepalived 

keepalived下载
http://www.keepalived.org/software/keepalived-1.2.5.tar.gz
  
解压 & ./configure   & make &  make install   完成安装。
