fabric报错:Fatal error: run() received nonzero return code 1 while executing!

今天在使用fabric远程安装rpm时,一直报:Fatal error: run() received nonzero return code 1 while executing!

这看起来也是没笔病呀,但fabric就是这么蛋疼, 它在执行过程中, 如果执行命令返回非零, 就会中断后面的逻辑.

 

解决方法就是忽略掉这个fabric的告警

env.warn_only=True

 

 

错误代码:

from  fabric.api import  *

env.user = 'root'
env.hosts = ['192.168.79.55',]
env.password = 'hadoop'

def install():
    run('rpm -ivh /root/py/psutils-p17-18-mdv2011.0.x86_64.rpm')

 

执行fab命令,就报下面这个错

 

添加 env.warn_only=True 就Ok了

from  fabric.api import  *

env.user = 'root'
env.hosts = ['192.168.79.55',]
env.password = 'hadoop'
env.warn_only=True

def install():
    run('rpm -ivh /root/py/psutils-p17-18-mdv2011.0.x86_64.rpm')
