Configure sersync for multi-server file synchronization

Sersync is mainly used for server synchronization, web images, and other functions. Developed based on boost1.43.0, inotifyapi, and rsynccommand. Currently, inotify-tools + rsync is the most widely used synchronization solution, and Openduckbill, an open-source google Project (dependent on inotify-tool ..

SersyNcIt is mainly used for server synchronization, web images, and other functions. Based on boost1.43.0, inotify api, rSyncCommand. Development. Currently, inotify-too is the most widely used synchronization solution.Ls+ Rsync, another Open-source google ProjectDuCkbill (dependent on inotify-tools), both of which are written in script language. Compared with the above two projects, the advantages of this project are:

1. SersyncIs written in c ++, andLinuxThe temporary files generated by the file system and repeated file operations are filtered (see appendix for details. This filtering script is not implemented). Therefore, when combined with rsync synchronization, this reduces runtime consumption and network resources. Therefore, it is faster.
2. Compared with the above two projects, sersync is easy to configure. The bin directory already has a basically statically compiled binary file, which can be used directly with the xml configuration file under the bin directory.
3. In addition, compared with other open-source scripts, this project uses multiple threads for synchronization. Especially when synchronizing large files, multiple servers can be synchronized in real time.
4. This project has an error handling mechanism. The failed queue is used to re-Synchronize the failed files. If the failed files still fail, the files that fail to be synchronized are re-synchronized every 10 hours.
5. This project comesCrontabFunction. You only need to enable the function in the xml configuration file to synchronize the configuration file at intervals according to your requirements. You do not need to configure the crontab function.
6. The socket and http plug-in extensions in this project meet your needs for secondary development.

The specific configuration is simple: Enable sersync on the synchronization master server, and configure rsync on the synchronization target server.

Synchronization master server configuration: assume that the master server ip address is 10.0.0.1, and the target server ip address is 10.0.0.2 and 10.0.0.3.
