#导出$ mysqldump -u root -p TUTORIALS tutorials_tbl > dump.txt#导入$ mysql -u root -p database_name < dump.txt#load datamysql> LOAD DATA LOCAL INFILE 'dump.txt' INTO TABLE mytbl;mysql> LOAD DATA LOCAL INFILE 'dump.txt' INTO TABLE mytbl -> FIELDS TERMINATED BY ':' -> LINES TERMINATED BY '/r/n';mysql>LOAD DATA LOCAL INFILE 'dump.txt' -> INTO TABLE mytbl (b, c, a);$ mysqlimport -u root -p --local database_name dump.txt
4，将导出的数据直接导入到远程的服务器
$ mysqldump -u root -p database_name / | mysql -h other-host.com database_name
