The script realizes automatic configuration of vsftp and shares the opt directory with other node machines to realize offline source configuration.
To use the script, you need to modify the following:
ftp_ip is the ftp server ip
reponame is the repo file name
dir is the warehouse directory, which is under opt by default.
houzui is an offline warehouse in the opt directory, and is written to houzui as an array.
Before use, you need to ensure that the server can download the vsftp service.
