shell编程系列25--shell操作数据库实战之备份MySQL数据，并通过FTP将其传输到远端主机备份mysql中的库或者表mysqldump
常用参数详解：
-u    用户名
-p    密码
-h    服务器ip地址
-d    等价于--no-data    只导出表结构
-t    等价于--no-create-info    只导出数据，不导出建表语句
-A    等价于--all-databases
-B    等价于--databases    导出一个或多个数据库需求：将school中的score表备份，并且将备份数据通过ftp传输到 10.11.0.148(windows) 的ftp的 bak 目录下FTP常用指令：open    与FTP服务器建立连接，例子：open 10.11.0.148user    有权限登录FTP服务器的用户名和密码，例子：user ftpuser ftpuser# 备份school库
[root@localhost shell]# mysqldump -udbuser -p123456 -h 10.11.0.215 school >school.sql
# 备份school库下的score表
[root@localhost shell]# mysqldump -udbuser -p123456 -h 10.11.0.215 school score >score.sql
# -A备份所有数据库，所有有权限的数据库
# mysqldump -udbuser -p123456 -h 10.11.0.215 -A >score.sql[root@localhost shell]# sh auto_backup.sh aaa
