Linux下sersync数据实时同步
<p>sersync其实是利用inotify和rsync两种软件技术来实现数据实时同步功能的，inotify是用于监听sersync所在服务器上的文件变化，结合rsync软件来进行数据同步，将数据实时同步给客户端服务器。</p>
<p>
工作过程：在同步主服务器上开启sersync，负责监听文件系统的变化，然后调用rsync命令把更新的文件同步到目标服务器上，主服务器上安装sersync软件，目标服务器上安装rsync服务。</p>

3、安装sersync服务</p>
<p>
采用inotify来对文件进行监控，当监控到文件有文件发生改变的时候，就会调用rsync实现触发式实时同步！</p>
<p>
安装sersync（注意sersync是工作在rsync的源服务器上，也就是客户端上）</p>
