distributeCopy.py

1. get_remote_model
   download file from remote to jumpserver which can ssh all server without password
2. do_local_copy copy file from jumpserver to remote prepare for [3] (below)
3. do_peer_copy ssh remoteserver and rsync from [2]

parallel_rsync [deprecated]

先决条件

1. 一台机器(master)可以免密码 ssh 到其他机器
2. 要同步文件的所有机器(client)配置 rsync

演示

master

192.168.1.50

client

['192.168.1.100', '192.168.1.101', '192.168.1.102', '192.168.1.103', '192.168.1.104', '192.168.1.105'...]

以2的 N 次方的步进并发 rsync

1. 192.168.1.50 scp file ==> 192.168.1.100

2. 192.168.1.100 ==> 192.168.1.101

3. 192.168.1.100 ==> 192.168.1.102

   192.168.1.101 ==> 192.168.1.103

4. 192.168.1.100 ==> 192.168.1.104

   192.168.1.101 ==> 192.168.1.105

   192.168.1.102 ==> 192.168.1.106

   192.168.1.103 ==> 192.168.1.107

5. 2的3次方

6. 2的4次方
