Use fabric to automatically launch small batches

During normal development, you should often encounter code online problems. Generally, there are several headaches:
<Ul>
<Li> a large number of hosts, but not many (1 ~ 100) </LI>
<Li> the launch process is cumbersome and error-prone </LI>
<Li> sudo may be required. You need to enter the sudo password multiple times. </LI>
</Ul>
Generally, you have two options:
<Ul>
<Li> <a href = "http://www.fabfile.org/" target = "_ blank"> fabric </a> written in python </LI>
<Li> <a href = "http://capistranorb.com/" target = "_ blank"> Capistrano </a> written in ruby </LI>
</Ul>
Then fabric is selected and the code is directly displayed.
