红帽企业集群和存储管理之rhcs高性能HA群集构建的简单应用
红帽企业集群和存储管理之rhcs高性能HA群集构建的简单应用案例应用拓扑图：案例应用实现详细步骤如下：
# hostname

You must restart the luci server for changes to take effect.
Run "service luci restart" to do so

故障模拟
继续轮询到node1节点上
首次轮询至node2.junjie.com成功！！
再次轮询至node1.junjie.com失败！！
本人不知后面如何处理，希望高手指点！！
学习了，不错，讲的太有道理了 我不在江湖,但江湖中有我的传说。 如果跟导师讲不清楚，那么就把他搞胡涂吧! 丑，但是丑的特别，也就是特别的丑！ 帮帮顶顶！！ 我的id是假冒的，大家不要相信我是骗子。
