Question

Let’s say that I have database1 and database2.

database1 – contains data

database2 – is empty.

---

I want to copy all data from database1 to database2 via SSH – duplicate database1.

What command should I use?

---

I have tried

mysqldump -u user -p database1 > database1.sql
Enter password: mysqldump: Got error: 1045: Access denied for user 'user'@'localhost' (using password: NO) when trying to connect

Answer 1

This will copy database from S1 to S2

mysqldump --opt <database> | gzip -c | ssh user@wherever 'cat > /tmp/yourfile.sql.gz'

Unzip file

gunzip /tmp/yourfile.sql.gz

Next you’ll have to import on S2

mysql -h<host> -u<user> -p<password> < /tmp/yourfile.sql
