集群配置同步工具 synctool 5.1 發布

synctool 是一個集群管理工具，用來在集群中的所有節點間進行保證配置文件的同步。節點可以是一個邏輯組和類的一部分，它們可能需要部分的配置文件。synctool 守護進程可以根據配置更改而對應用進行重啟，還包括執行一些其他的管理任務。

synctool simplifies system administration by working with the following concepts:

• a host can be part of one or more groups, or classes
• files are designated a group by means of filename extension
• the ‘overlay’ directory tree contains the files and directories that should be copied (or ‘synced’) to the target host
• when certain files are updated, you will want to execute a script (e.g, /etc/init.d/daemon restart)
• simplicity. It uses the power of rsync and ssh to distribute the files
• extendibility. Make synctool more powerful by writing plugin scripts
