Online MySQL backup and remote copy to Remote Backup Server shell script

This script implements the following functions: 1. Backing up mysql databases online; 2. Saving backup logs to log files; 3. compressing data backup files; 4. Remotely ftp the compressed file to the backup server; 5. deleting data that has been backed up locally for more than seven days is mainly to prevent the abnormal growth of the disk space of the production server from leading to performance bottlenecks. The specific implementation of shell is as follows :#! /Bin/sh
