Two types of parallel method code for fabric

Fabric is a Python class library that uses SSH protocol-based command-line tools for application Deployment and System task management, and here are two ways that fabric code runs in parallel:

1: Parameter-P

From FABRIC.API import *  host1 = ' root@ip1:22 '  host2 = ' root@ip2:22 '   env.hosts = [Host1, host2]   Env.pass Words = {      host1: "P1",      host2: "P2"  }                                                                                                                                                                                                                     def BACKUP_AND_CP (): With      CD ("/home/**"):          run (' ls ')

And then  run Fab-p  backup_and_cp.

2: Decorator

Import timefrom fabric.api Import *host1 = ' root@ip1:22 ' host2 = ' root@ip2:22 '  env.hosts = [Host1, host2]  Env.pass Words = {      host1: "P1",      host2: "P2"  }  @parallel                                                                                                                                                                                                                     def BACKUP_AND_CP (): With      CD ("/home/**"):          run (' ls ')

Running Fab BACKUP_AND_CP is OK.
