mysqldump备份脚本

• 备份全库

mysqldump -uroot -p --single-transaction --flush-logs -R -E  --all-databases --set-gtid-purged=off --master-data=2  >/root/backup-`date +%F-%H-%M-%S`.sql

• 备份单库

mysqldump -uroot -p --single-transaction --flush-logs -R -E   --databases DB_NAME --set-gtid-purged=off --master-data=2  >/root/backup-`date +%F-%H-%M-%S`.sql

• 备份多库

mysqldump -uroot -p --single-transaction --flush-logs -R -E  -B DB1 DB2 --set-gtid-purged=off --master-data=2  >/root/backup-`date +%F-%H-%M-%S`.sql

• 只备份单库下的全部表结构：

mysqldump  --databases DB_NAME  --no-data --single-transaction --flush-logs --set-gtid-purged=off > /root/backup-`date +%F-%H-%M-%S`.sql

• 单库下只备份某些表结构：

mysqldump   DB_NAME  --no-data table1  table2    --single-transaction --flush-logs   --skip-dump-date --set-gtid-purged=off --master-data=2  > /root/backup-`date +%F-%H-%M-%S`.sql

• 单库下的只备份数据(不带表结构)：

mysqldump    DB_NAME   -t    --single-transaction --flush-logs    --set-gtid-purged=off --master-data=2  > /root/backup-`date +%F-%H-%M-%S`.sql

• 单库下的只备份某些表的数据(不带表结构)：

mysqldump    DB_NAME   -t  table1 table2  --single-transaction --flush-logs    --set-gtid-purged=off --master-data=2  > /root/backup-`date +%F-%H-%M-%S`.sql

• 备份单库下的某些表(带表结构):

mysqldump   DB_NAME   table1  table2   --single-transaction --flush-logs  --set-gtid-purged=off --master-data=2  > /root/backup-`date +%F-%H-%M-%S`.sql

• 抽出为csv格式：

select * from t_user  into outfile '/tmp/t_user.csv' fields terminated by ',' optionally enclosed by  '"' escaped by '"' lines terminated by '\r\n';

• 导入：

load data infile  '/tmp/t_user.csv' into table table_name fields terminated by ',' optionally enclosed by  '"' escaped by '"' lines terminated by '\r\n';
