keepalived+ipvsadm 安装

1.下载keepalived

   yum -y install gcc makeopenssl openssl-devel wget kernel-devel

   http://www.keepalived.org/software/keepalived-1.1.20.tar.gz

2.下载ipvsadm

  wgethttp://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz
3.安装。在安装keepalived出现以下错误：Use IPVSFramework      : No

 Keepalivedversion      : 1.1.15
 Compiler                : gcc
 Compilerflags          : -g -O2
 ExtraLib               : -lpopt -lssl -lcrypto
 Use IPVSFramework      : No
 IPVS sync daemon support : No
 Use VRRPFramework      : Yes

以上错误，需要先安装kernel-devel

./configure--with-kernel-devel=/usr/src/kernels/2.6.18-308.20.1.el5-i686

则可以安装成功。

 cp/usr/local/etc/sysconfig/keepalived   /etc/sysconfig/

5.设置为服务开机启动
