mysql5.7上使用mysqldump

# mysqldump -utmp -ptmp -h127.0.0.1 -P3307   --single-transaction --master-data=2  --all-databases > 3307_20191123.sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed suppressed parts of the database. If you don't want to restore GTIDs, pass --set-gtid-purged=OFF. To make
a complete dump, pass --all-databases --triggers --routines --events.# 

mysqldump -utmp -ptmp -h127.0.0.1 -P3307   --single-transaction --master-data=2  --all-databases > 3307_20191123.sql
