Users registering for Metabase are all stored in a file named “metabase. db. mv. db”. How can I view the specific data in the file?
I tried using the command java-cp metabase.jar org.h2.tools.Server-web
But what are the usernames and password?
There isn’t any username or password for that database by default.
It is not recommended to use H2 in production, you should migrate to another database:
Okay, I’d like to try to replace the H2 database with Mysql in the production process.
If the Mysql database is replaced, is there any requirement for the encoding of the database? If so, what should the character set and sorting rules be?
If you choose MySQL (I would recommend MariaDB), then you should use charset
If you use MySQL 8, then you need to use
mysql_native_password instead of
caching_sha2_password for user credentials (otherwise you’ll see an error)
Not sure what you mean by “encoding of the database” ?
The character set I am using at present is UTF-8, and the sorting rule is utf8_unicode_ci.
But it’s scrambled.
What do you normally use for charset/collation? Then use that.
You should not be using
utf8 - you should use
Hello, the character encoding of the database is as follows when doing data migration.
But there is still a scrambling problem.
It looks like you’re showing column
query.query_hash, which should be a
binary(32) type, so it shouldn’t be affected by any encoding.
You’re right. He’s really a binary (32) type, but in my opinion my data is more like garbage. What do you think?
@zsk It’s not supposed to be viewed by humans - it’s for computer eyes only
Thank you very much for your answer? So how do I test that the stored values are correct? (What functions or buttons should I manipulate to invoke the data in this table)
I don’t understand your question. The data is correct - it’s
binary, so encoding should not have any impact on that column.
The data inside
query.query_hash is a
sha256 hash (if I remember correctly). It is used as an identifier to other tables such as
query_execution - and as a check if data has changed (cache).
As you said, I tried without any mistakes. I think it is possible. Thank you very much.
By the way, if I use Nginx to load balance multiple instances of Metabase and use the default polling strategy, will it cause the problem that sessions cannot be shared?
@zsk I don’t know what “default polling strategy” means. You should use sticky connections, so each session stays with the same instance.
