1.導出整個數據庫
MySQLdump -u 用戶名 -p 數據庫名 > 導出的文件名
MySQLdump -u wcnc -p smgp_aPPS_wcnc > wcnc.sql
2.導出一個表
MySQLdump -u 用戶名 -p 數據庫名 表名> 導出的文件名
MySQLdump -u wcnc -p smgp_aPPS_wcnc users> wcnc_users.sql
3.導出一個數據庫結構
MySQLdump -u wcnc -p -d --add-drop-table smgp_aPPS_wcnc >d:wcnc_db.sql
-d 沒有數據 --add-drop-table 在每個create語句之前增加一個drop table
4.導入數據庫
常用source 命令
進入MySQL數據庫控制台，
如MySQL -u root -p
MySQL>use 數據庫
然後使用source命令，後面參數為腳本文件（如這裡用到的.sql）
MySQL>source d:wcnc_db.sql
alan發現有的時候source會出現亂碼，尤其是在liunx下，也可以這樣導入
導入數據庫 MySQL -u root -p dbmane < db.sql;
=====================================
外加整理下liunx權限的命令，免的每次的都要一個目錄一個目錄的該權限
-rwx------ :等於數字表示700。
-rwxr—r--:等於數字表示744。
-rw-rw-r-x:等於數字表示665。
drwx—x—x:等於數字表示711。
drwx------:等於數字表示700。
chmod 777 /home/user 單目錄權限
chmod -R 777 /home/user 所有子目錄

2.導出一個表
格式：MySQLdump -u 用戶名 -p 數據庫名 表名> 導出的文件名
舉例：表結構與上面的相同,命令如下：
C:MySQLMySQL Server 5.0bin>MySQLdump -u root -p testdb user > user.sql
Enter passWord:
C:MySQLMySQL Server 5.0bin>
user.sql內容如下：
-- MySQL dump 10.10
--
-- Host: localhost Database: testdb
-- ------------------------------------------------------
-- Server version 5.0.7-beta-nt
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;

--
-- Table structure for table `user`

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (

3.導出一個數據庫結構
格式：MySQLdump -u 用戶名 -p -d --add-drop-table 數據庫 > 導出的文件名
說明：-d 選項表示沒有數據
--add-drop-table 選項說明在每個create語句之前增加一個drop table
舉例：表結構與上面的相同
C:MySQLMySQL Server 5.0bin>MySQLdump -u root -p -d --add-drop-table testdb > testdbstruct.sql
Enter passWord:
C:MySQLMySQL Server 5.0bin>
testdbstruct.sql內容如下：
-- MySQL dump 10.10
--
-- Host: localhost Database: testdb
-- ------------------------------------------------------
-- Server version 5.0.7-beta-nt
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;

Enter passWord:
