道不尽声声珍重
默默地祝福平安
人间事常难遂人愿
且看明月又有几回圆
远去矣，远去矣

大气，正气，史诗历史大剧，值得一看！
赞同余世维说过的"法家思想再兴旺发达一点，就不一样了……“！
原著《大秦帝国》的作者孙皓晖教授是法家的fans，此书共六部，值得一读。彩！

LVS + Keepalived 之DR实现

LVS原理可以看章博士的文章，Keepalived在这里主要用作RealServer的健康状态检查以及LoadBalance主机和BackUP主机之间failover的实现
OS: CentOS5.2/RHEL5.2
VIP: 129.0.3.236
LoadBalance : 129.0.3.230
BackUP: 129.0.3.231
RealServer1: 129.0.3.233
RealServer2: 129.0.3.234
1. LoadBalance配置
设置
安装ipvsadm
下载地址：http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz
如果编译错误，看时候做了内核的软连接 /usr/src/linux
然后 make && make install
配置lvs
依次执行：

LoadBalance : 129.0.3.230
BackUP: 129.0.3.231
RealServer1: 129.0.3.233
RealServer2: 129.0.3.234
1. LoadBalance配置
设置
net.ipv4.ip_forward = 1
安装ipvsadm
