MySQL用作备份还原的导入和导出命令用法整理

#> cd /usr/local/src
#> /usr/local/mysql/bin/mysqldump -uroot -p123456 cacti > cacti.sql;

　　mysqldump -u 用户名 -p 数据库名 > 导出的文件名
　　mysqldump -u root -p abc > abc.sql

　　mysqldump -u 用户名 -p 数据库名 表名> 导出的文件名
　　mysqldump -u root -p abc users> abc_users.sql

　　mysqldump -u root -p -d --add-drop-table abc >/usr/local/abc_db.sql
　　-d 没有数据 --add-drop-table 在每个create语句之前增加一个drop table

#> /usr/local/mysql/bin/mysql -uroot -p
mysql> create database cacti;   新建数据库名为cacti
mysql> use cacti;              选择目标数据库
mysql> source /usr/local/src/cacti.sql   导入数据库
