CentOS 6.5 Inotify+rsync Do real-time synchronization-Enterprise Instance (1.0)

Inotify+rsync real-time synchronization origin and introduction

INotify Service mechanism

INotify Implementation Preparation

The INotify configuration is based on the rsync service

Inotify,sersync,lsyncd

Sersync function More, can do a variety of filtering, but from a performance perspective, through the test results inotify higher performance, can sync good hundreds of images per second, inotify 150 can not be real-time

Check rsync daemon before implementation is normal

And can be pushed normally
