keepalived脑裂现象

keepalived脑裂现象是指在keepalived主备架构的环境中，当主备机器之间的通信出现问题时，会导致keepalived系统中出现双主的情况，从而产生资源竞争的现象。[3]这种情况可能会导致虚拟 IP 移除不掉，进而引发脑裂的现象。

为了避免keepalived脑裂现象，可以采用第三方仲裁的方法。这种方法可以通过引入一个第三方设备，例如硬件负载均衡器，来监控主备机器之间的通信状态。当主备机器之间的通信出现问题时，第三方设备可以及时感知到，并决定哪一个机器应该拥有虚拟 IP。这样可以有效避免脑裂现象的发生。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
