我的代码备份mysql问题然后上传到服务器ftp？

Question

我想尝试将自己的自动匹配mysql备份到我的ftp服务器，但是当我尝试这样做时。它不想将它发送到我的服务器，但如果我手动执行它就可以了

 open xxxx
    user $xxx $xx
    cd $xxx
    put $xxx
    close
    bye

bash脚本

 #!/bin/bash
    user=zzzzzzzz
    password=zzzzzzzz
    host=localhost
    db_name=zzzzzzzz
    #backup_path="/var/www/html/storelte/database"
    date=$(date +"%d-%b-%Y")
    file=$db_name-$date.sql

    ############### Local Backup  ########################
    mysqldump  --routines --user=$user --password=$password --host=$host $db_name > $file
    gzip -9 $file
    ############### FTP details  #########################
    FTP_SERVER=xxxxxx
    FTP_USERNAME="xxxxxx"
    FTP_PASSWORD="xxxxxx"
    FTP_UPLOAD_DIR="/database"
    FTP_FILE = $db_name-$date.sql.gz
    #ftp -inv $FTP_SERVER << EOF
    #user $FTP_USERNAME $FTP_PASSWORD
    #cd $FTP_UPLOAD_DIR
    #put $file_name
    #close
    #bye
    #EOF

    ftp -inv << EOF
        open $FTP_SERVER
        user $FTP_USERNAME $FTP_PASSWORD
        cd $FTP_UPLOAD_DIR
        put $FTP_FILE
        close
        bye
    EOF

输出

<p>./database.sh: line 18: FTP_FILE: command not found
Connected to xxx.xxx.xxxx.xxxx.
