当我定义要在多个远程服务器上运行的任务时,如果任务在服务器1上运行并退出并出现错误,则Fabric将停止并中止该任务.但是我想让Fabric忽略错误并在下一个服务器上运行任务.我该怎么做呢？
例如:
$ fab site1_service_gw
[site1rpt1] Executing task 'site1_service_gw'
[site1fep1] run: echo 'Nm123!@#' | sudo -S route
[site1fep1] err:
[site1fep1] err: We trust you have received the usual lecture from the local System
[site1fep1] err: Administrator. It usually boils down to these three things:
[site1fep1] err:
[site1fep1] err: #1) Respect the privacy of others.
[site1fep1] err: #2) Think before you type.
[site1fep1] err: #3) With great power comes great responsibility.
[site1fep1] err: root's password:
[site1fep1] err: sudo: route: command not …我有以下fabfile.py:
from fabric.api import env, run
host1 = '192.168.200.181'
host2 = '192.168.200.182'
host3 = '192.168.200.183'
env.hosts = [host1, host2, host3]
def df_h():
run("df -h | grep sda3")
我得到以下输出:
[192.168.200.181] run: df -h | grep sda3
[192.168.200.181] out: /dev/sda3 365G 180G 185G 50% /usr/local/nwe
[192.168.200.183] run: df -h | grep sda3
[192.168.200.183] out: /dev/sda3 365G 41G 324G 12% /usr/local/nwe
[192.168.200.182] run: df -h | grep sda3
[192.168.200.182] out: /dev/sda3 365G 87G 279G 24% /usr/local/nwe
Done.
Disconnecting from 192.168.200.182... done.
