The Go language implementation automatically uploads Web logs through the FTP library _golang

Because the Web server that is normally managed is a VM server, in order to save hard disk space, generally to the virtual machine allocation of hard disk space is relatively small, only 8G, because, can not save how many logs, so every day need to transfer each Web log to a larger server on a hard disk, and then use NBU centralized backup , this program uses the Go language implementation to automatically upload the Web log FTP server via FTP, using the filepath. Walk traverses the log directory and the third party Pure Go Library "github.com/jlaffaye/ftp", while the log VM local storage path format is/var/log/weblog/www.domainname.com/month/20140616. Access.log,
