mysqldump -h [host] -p -u [user] [database name] > filename.sql

localhost中的示例

mysqldump -h localhost -p -u root cookbook > cookbook.sql

你可以使用下面的命令，

Mysqldump——databases——user=root——password your_db_name > export_into_db.sql

生成的文件将在运行此命令的同一目录中可用。

你可以找到更多关于mysqldump的官方参考:Import Export MySQL DB

注意:使用——databases代替——database，因为不再支持最后一个。

享受:)

首先 打开命令提示符，然后在CMD中打开bin目录(我希望你知道CMD命令) 进入WAMP程序文件中MySql文件夹的bin目录。

运行命令

mysqldump -u db_username -p database_name > path_where_to_save_sql_file

按enter system将导出特定的数据库并创建SQL文件到给定的位置。

我希望你能做到。 如果你有任何问题，请告诉我。

您可以使用此脚本从终端导出或导入任何数据库 网址:https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh

echo -e "Welcome to the import/export database utility\n"
echo -e "the default location of mysqldump file is: /opt/lampp/bin/mysqldump\n"
echo -e "the default location of mysql file is: /opt/lampp/bin/mysql\n"
read -p 'Would like you like to change the default location [y/n]: ' location_change
read -p "Please enter your username: " u_name
read -p 'Would you like to import or export a database: [import/export]: ' action
echo

mysqldump_location=/opt/lampp/bin/mysqldump
mysql_location=/opt/lampp/bin/mysql

if [ "$action" == "export" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysqldump that you want to use: ' mysqldump_location
        echo
    else
        echo -e "Using default location of mysqldump\n"
    fi
    read -p 'Give the name of database in which you would like to export: ' db_name
    read -p 'Give the complete path of the .sql file in which you would like to export the database: ' sql_file
    $mysqldump_location -u $u_name -p $db_name > $sql_file
elif [ "$action" == "import" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysql that you want to use: ' mysql_location
        echo
    else
        echo -e "Using default location of mysql\n"
    fi
    read -p 'Give the complete path of the .sql file you would like to import: ' sql_file
    read -p 'Give the name of database in which to import this file: ' db_name
    $mysql_location -u $u_name -p $db_name < $sql_file
else
    echo "please select a valid command"
fi

进口:

mysql -u db_username -p newFileName < databasName.sql

出口:

mysqldump -u db_username -p databasName > newFileName.sql

给出这个命令来导出您的数据库，这将包括日期

mysqldump -u[username] -p[userpassword] --databases yourdatabase | gzip > /home/pi/database_backup/database_`date '+%m-%d-%Y'`.sql.gz

(-p后没有空格)
