Then I’ve developed MySQL backup script I’ve faced an error:
mysqldump: Got error: 1045: "Access denied for user '...'@'localhost' (using password: YES)" when using LOCK TABLES
which was fixed by adding
--lock-tables=false
parameter to mysqldump command.
Also, if you dump InnoDB tables consider using the
--single-transaction=true
parameter. As it is described in MySQL 5.7 documentation page.
