mysql怎么用命令行导出sql文件_MySQL：如何从命令行导出和导入.sql文件？

要导出

如果是整个数据库&＃xff0c;那么&＃xff1a;

$ mysqldump -u [uname] -p[pass] db_name > db_backup.sql

如果是全部数据库&＃xff0c;那么&＃xff1a;

$ mysqldump -u [uname] -p[pass] --all-databases > all_db_backup.sql

如果它是DB中的特定表&＃xff0c;则&＃xff1a;

$ mysqldump -u [uname] -p[pass] db_name table1 table2 > table_backup.sql

你甚至可以使用gzip自动压缩输出(如果你的数据库非常大)&＃xff1a;

$ mysqldump -u [uname] -p[pass] db_name | gzip > db_backup.sql.gz

如果您想远程执行此操作&＃xff0c;并且有权访问相关服务器&＃xff0c;则可以使用以下命令(假定MySQL服务器位于端口3306上)&＃xff1a;

$ mysqldump -P 3306 -h [ip_address] -u [uname] -p[pass] db_name > db_backup.sql

导入

键入以下命令导入sql数据文件&＃xff1a;

$ mysql -u username -p -h localhost DATA-BASE-NAME

在这个例子中&＃xff0c;使用sat作为用户名将&＃39;data.sql&＃39;文件导入&＃39;blog&＃39;数据库&＃xff1a;

$ mysql -u sat -p -h localhost blog

如果您有专用的数据库服务器&＃xff0c;请使用实际的服务器名称或IP地址replacelocalhost主机名&＃xff0c;如下所示&＃xff1a;

$ mysql -u username -p -h 202.54.1.10 databasename

或者使用主机名&＃xff0c;例如mysql.cyberciti.biz

$ mysql -u username -p -h mysql.cyberciti.biz database-name

如果您不知道数据库名称或数据库名称包含在SQL转储&＃xff0c;您可以尝试如下所示&＃xff1a;

$ mysql -u username -p -h 202.54.1.10

请参阅&＃xff1a; http &＃xff1a; //dev.mysql.com/doc/refman/5.6/en/mysqldump.html

如果你想要一个GUI工具&＃xff0c;那么你可以使用SQLyog

键入以下命令导入sql数据文件&＃xff1a;

$ mysql -u username -p -h localhost DATA-BASE-NAME

在这个例子中&＃xff0c;使用vivek作为用户名将&＃39;data.sql&＃39;文件导入&＃39;blog&＃39;数据库&＃xff1a;

$ mysql -u vivek -p -h localhost blog

如果您有专用的数据库服务器&＃xff0c;请使用实际的服务器名称或IP地址replacelocalhost主机名&＃xff0c;如下所示&＃xff1a;

$ mysql -u username -p -h 202.54.1.10 databasename

要导出数据库&＃xff0c;请使用以下命令&＃xff1a;

mysqldump -u username -p databasename > filename.sql

请注意每种情况下的符号。

尝试

mysqldump databaseExample > file.sql

如果您已经在运行SQL shell&＃xff0c;则可以使用source命令导入数据&＃xff1a;

use databasename; source data.sql;

mysqldump不会转储数据库事件&＃xff0c;触发器和例程&＃xff0c;除非在转储个别数据库时明确指出;

mysqldump -uuser -p db_name --events --triggers --routines > db_name.sql

将整个数据库转储到文件中&＃xff1a;

mysqldump -u USERNAME -p password DATABASENAME > FILENAME.sql

那么你可以使用下面的命令导出&＃xff0c;

mysqldump –database –user &＃61; root –password your_db_name> export_into_db.sql

并且生成的文件将在您运行此命令的同一目录中可用。

现在用命令login到mysql&＃xff0c;

mysql -u [用户名] -p

然后在文件path中使用“source”命令。

您可以使用此脚本导出或导入从此链接提供的任何数据库&＃xff1a; 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 &＃39;Would like you like to change the default location [y/n]: &＃39; location_change read -p "Please enter your username: " u_name read -p &＃39;Would you like to import or export a database: [import/export]: &＃39; action echo mysqldump_location&＃61;/opt/lampp/bin/mysqldump mysql_location&＃61;/opt/lampp/bin/mysql if [ "$action" &＃61;&＃61; "export" ]; then if [ "$location_change" &＃61;&＃61; "y" ]; then read -p &＃39;Give the location of mysqldump that you want to use: &＃39; mysqldump_location echo else echo -e "Using default location of mysqldump\n" fi read -p &＃39;Give the name of database in which you would like to export: &＃39; db_name read -p &＃39;Give the complete path of the .sql file in which you would like to export the database: &＃39; sql_file $mysqldump_location -u $u_name -p $db_name > $sql_file elif [ "$action" &＃61;&＃61; "import" ]; then if [ "$location_change" &＃61;&＃61; "y" ]; then read -p &＃39;Give the location of mysql that you want to use: &＃39; mysql_location echo else echo -e "Using default location of mysql\n" fi read -p &＃39;Give the complete path of the .sql file you would like to import: &＃39; sql_file read -p &＃39;Give the name of database in which to import this file: &＃39; db_name $mysql_location -u $u_name -p $db_name <$sql_file else echo "please select a valid command" fi

thx &＃64;Hariboo&＃xff0c;添加事件/触发器/路由参数

mysqldump -x -u [uname] -p[pass] -C --databases db_name --events --triggers --routines | sed -e &＃39;s/DEFINER[ ]*&＃61;[ ]*[^*]*\*/\*/ &＃39; | awk &＃39;{ if (index($0,"GTID_PURGED")) { getline; while (length($0) > 0) { getline; } } else { print $0 } }&＃39; | grep -iv &＃39;set &＃64;&＃64;&＃39; | trickle -u 10240 mysql -u username -p -h localhost DATA-BASE-NAME

一些问题/提示&＃xff1a;

错误&＃xff1a;……在使用LOCK TABLES时不存在

# --lock-all-tables&＃xff0c;-x , this parameter is to keep data consistency because some transaction may still be working like schedule. # also you need check and confirm: grant all privileges on *.* to root&＃64;"%" identified by "Passwd";

错误2006(HY000)在866行&＃xff1a;MySQL服务器已经消失mysqldump&＃xff1a;写到errno 32

# set this values big enough on destination mysql server, like: max_allowed_packet&＃61;1024*1024*20 # use compress parameter &＃39;-C&＃39; # use trickle to limit network bandwidth while write data to destination server

错误1419(HY000)在行32730&＃xff1a;您没有SUPER权限和启用二进制日志logging(您可能希望使用不太安全的log_bin_trust_function_creatorsvariables)

# set SET GLOBAL log_bin_trust_function_creators &＃61; 1; # or use super user import data

错误1227(42000)在行138&＃xff1a;访问被拒绝; 你需要(至less有一个)SUPER权限(s)用于这个操作mysqldump&＃xff1a;在写入时得到errno 32

# add sed/awk to avoid some privilege issues

希望这个帮助&＃xff01;
