system load, especially when several hundred megabytes of large packets are encountered, which not only occupies the bandwidth, in addition, the subsequent compressed packages are blocked, which affects the real-time processing of website content. In addition, dynamic application updates occupy a large amount of time in our daily work and are repetitive and boring, one thing that is completely technical is that for some applications that only have two or three servers, it takes a little time an

Inotify + unison implement bidirectional Real-time Data SynchronizationA new project was created a few days ago. The website architecture is that the front-end uses nginx to reverse proxy the two backend tomcat servers. At this time, the data between the two tomcat servers is synchronized in real time, which becomes a problem? I have searched for many solutions on the Internet. There are several methods for file synchronization under liux: 1. nfs for

Unios can keep the content consistent between the two folders on the local disk and synchronize network data. Features: cross-platform 1. No special requirements on kernel and User Permissions 2.

The project has a new demand, in more than one app server randomly upload Pictures/resource files, one of the app needs to read the uploaded images, so that the previous rsync+inotify settings will not be able to deal with.So we study the next multi-directional trigger real-time synchronization mechanism, we can experiment, if there is inappropriate place, please contact me to amend, thank you.Here's the start.First, IntroductionUnison is a file Sync tool that can be used under Windows, Linux, a

The installation of unison under MacOSX-Linux Enterprise Application-Linux server application information. The following is a detailed description. Unison is a cross-platform file synchronization tool that not only supports local synchronization, but also supports synchronization through network protocols such as SSH, RSH, and Socket. Unison supports both one-way

also has a corresponding version under the Windows platform, such as Cwrsync and Sync2nas tools. The basic features of rsync are as follows: 1. Can be mirrored to save the entire directory tree and file system; 2. It is easy to maintain the original file permissions, time, soft and hard links, etc. 3. No special permission is required to install; 4. Optimized process, high file transfer efficiency; 5. You can transfer files using rsh, SSH, etc. , of course, can also be connected via a direct so

Unison is a free and cross-platform file synchronization tool. With it, we can save two sets of file copies (instances) on two different platforms, or save it on different disks of the same system. Unlike a simple image method or backup utility, Unison can update two copies of the distributed directory structure at the same time. It can detect and display conflicting updates. Unlike distributed file systems

The multi-machine data synchronization mechanism Unison + inotify-tools was accidentally encountered in the QQ group this morning when I heard a problem about two-way Real-Time Synchronization of different machines. When I thought of it, I found that the database (mysql ), it seems that the two-way real-time synchronization technology seems very limited, not to mention the need to achieve two-way Real-Time Synchronization of multiple machines, a varie
