Keepalived+LVS-DR方式配置高可用负载均衡集群

Keepalived+LVS-DR模式配置高可用负载均衡集群

环境: 虚拟机:VMware Workstation          操作系统:CentOS 5.5

一、keepalived+lvs-DR模式配置高可用负载均衡

拓扑如下：

二、服务器ip配置信息

1. ip_lb 主机(master) :

 

2.ip_lb_2 主机 (backup)

3.web1 主机

4.web2 主机

三、在master和backup分别查看是否有ipvsadm软件

1. 检查ipvsadm是否安装成功.可以直接输入

[root@localhost ~]# ipvsadm

# PS:这里说的LVS.并不是用ipvsadm软件配置.而是直接用keepalived的virtual_server配置项控制的.
#  安装ipvsadm只是可以看到负载状况.其实只需要keepalived也可以实现负载均衡集群.

六、在web1和web2主机上配置LVS-DR的相关配置.
1. vim /etc/init.d/lvsDR_node   （web1主机）
<br><br>九、测试断开一个web服务或加入一个web服务<br>现在关闭 web2主机(192.168.96.4) 的web 服务..<br>查看日志可以看到:<br><img src="//img.reader8.com/uploadfile/jiaocheng/20140189/2819/2014012819193836209.jpg" alt="Keepalived+LVS-DR方式配置高可用负载均衡集群"><br><br>现在再把 web2主机(192.168.96.4)的web 服务加入进来:<br>查看日志可以看到:<br><img src="//img.reader8.com/uploadfile/jiaocheng/20140189/2819/2014012819193836210.jpg" alt="Keepalived+LVS-DR方式配置高可用负载均衡集群"><br><br>十、 测试HA<br>现在模拟主(master)的keepalived主机死掉. <br>备机的日志文件:<br><img src="//img.reader8.com/uploadfile/jiaocheng/20140189/2819/2014012819193836211.jpg" alt="Keepalived+LVS-DR方式配置高可用负载均衡集群"><br><br>可以看到备机的keepalived已经开始工作....<br><br>整个部署就完成了.<br><br>官方参考中文文档:http://www.keepalived.org/pdf/sery-lvs-cluster.pdf<br><br><br><p></p> </p><div class="aged2"><script type="text/javascript">a("article_content_down");</script></div> </div> <div id="pagebox" > <a href="/jiaocheng/vsts/" target="_blank">查看更多</a> <A href="/jiaocheng/20121231/2060381.html" title="卸载VMware在Visual Studio 2008下的插件">下一篇</A></div> <div id="MainLeftll"> <div id="MainLeftllToolbar">本文网址：<a href="https://www.reader8.com/jiaocheng/20120620/2060385.html">https://www.reader8.com/jiaocheng/20120620/2060385.html</a></div> <div class="related"><span class="relatedIco1">读书人精选</span> <ul class="relatedList"> </ul> </div> <div class="aged3"><script type="text/javascript">a("article_content_down2");</script></div> <div class="aged3a"><script type="text/javascript">a("article_content_down3");</script></div> </div> </div> <!-- 文章正文左边结束 --> <!-- 文章正文右边开始 --> <div class="leftbox_r"> <div class="aged4"><script type="text/javascript">a("article_right_up");</script></div> <div class="Rtitle"> <span class="Rtitle_text">热点排行</span></div> <div class="RContl"> <ul> <li><a href="/jiaocheng/20131013/2062199.html" target="_blank">[VS2010]逸雨清风 恒久稳定音乐外链生成</a></li> <li><a href="/jiaocheng/20130409/2062909.html" target="_blank">vs 2012自带封装工具进行部署安装</a></li> <li><a href="/jiaocheng/20130329/2060579.html" target="_blank">用VS2012干MFC ActiveX控件并使用html、</a></li> <li><a href="/jiaocheng/20131001/2060013.html" target="_blank">vs2012布局有关问题</a></li> <li><a href="/jiaocheng/20120715/2062142.html" target="_blank">使用VS2005开发 mobile无法调试的解决办</a></li> <li><a href="/jiaocheng/20130325/2060139.html" target="_blank">VS08 装配与部署 将应用程序添加到启动项</a></li> <li><a href="/jiaocheng/20131001/2061833.html" target="_blank">Java VS C++ (1)注释</a></li> <li><a href="/jiaocheng/20121024/2061901.html" target="_blank">PHP运用客户端传复杂参数，JSON vs jQue</a></li> <li><a href="/jiaocheng/20131008/2059695.html" target="_blank">C# VS2012操作word文档.(2)</a></li> <li><a href="/jiaocheng/20130701/2061569.html" target="_blank">CVS做的sso单点登录（集成普元BPS）报这</a></li> </ul> </div> <div class="aged7"><script type="text/javascript">a("article_right_up2");</script></div> <!-- 文章正文右边结束 --> </div> <!--主体结束--> <script type="text/javascript">a("article_down_up");</script> <script type="text/javascript">a("foot");</script> <script type="text/javascript">a("article_down_up2");</script> <!--主体结束--> <div style="display:none"> <!--百度统计代码--> <script> var _hmt = _hmt || []; (function() { var hm = document.createElement("script"); hm.src = "https://hm.baidu.com/hm.js?d6151f323a57d16696165e47eee86d53"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(hm, s); })(); </script> </div> <script type="text/javascript">a("allbt");</script> </body> </html>
