目的：将服务器的mysql中的数据导入到本地
设备：本地：Mac。 远程服务器：linux
使用ssh登录服务器
mysqldump -u [username] -p [database_name] > [/path/dumpfilename.sql]
例如：
`mysqldump -u root -p mywordpress > /var/mywordpress.sql
在Mac上使用软件filezilla将第2步导出的mywordpress.sql下载到本地
mysql -u [username] -p [database_name] < [dumpfilename.sql]
其中，database_name需要是本地数据库中已存在的数据库，比如新建一个。
