Import 5gb sql file into MYSQL database

[girish]

@vadim I would give MySQL a lot of memory for a start - https://docs.cloudron.io/services/#configure . Was there any error message during abort?

[vadim]

No any way. I have on test server 4gb RAM, i set to max for mysql. During long time it is importing, then web terminal resets.

@vadim the systemctl command can only be run via SSH (and not the web terminal).

If you are comfortable with docker, you can try one more thing:

• SSH into server
• Find the container of the traccar app. You can find this from docker ps | grep traccar
• docker exec -ti <containerid> /bin/bash . Do the MySQL import here .

Thing is I suspect the web terminal is disconnecting because the command is running too long. Maybe there are proxies in the middle that disconnect the connection. There could be many reasons (OS/Network/Firewall/Proxy/Browser...). Doing docker exec directly atleast rules out most of the issues.

FWIW, the few times I have a large DB which wouldn't import I just opened the sql file in a local DB app, and copied and pasted section by section. Took awhile, but ultimately quicker than banging my head against a wall.

The issue here is that disk speed is quite low (90Mb/sec). To track the slow progress:

• Put app in recovery mode
• apt update && apt install pv
• pv traccar.sql | mysql --user=${CLOUDRON_MYSQL_USERNAME} --password=${CLOUDRON_MYSQL_PASSWORD} --host=${CLOUDRON_MYSQL_HOST} ${CLOUDRON_MYSQL_DATABASE}

FWIW, it imported in < 10 mins in my test installation on DigitalOcean.

I have tried so many times, everything upgraded on source server, did dumps for many times and after import I don't see any data on Cloudron installation. Just blank traccar with demo login.

@BrutalBirdie said in Import 5gb sql file into MYSQL database:

You can always directly upload it to the root server and move it into the /app/data/ folder.
Just rsync the file to the root server and move it to /home/yellowtent/appdata/{ID}/data/

@vadim this is one of the most save ways to get the file to the server.
Once on the root system you can copy it over and over for trying out different solutions so you don't have to wait for the upload over and over again.

[vadim]

@BrutalBirdie I have sql files in /app/data and use this way. But every import is blank. No way to get data from source service.

I have Traccar installed for 4 years since very old version. DB works perfect with new version. Could be there a problem with "old" db trying to import to a new installation?

[girish]

@vadim so the DB is importing but you have to make sure that you import the database into the right version of traccar. Which version of traccar were you using?

Also, after import, have you tried inspecting the tables? Make sure you were not using any table prefixes etc.

[vadim]

@girish I have version 5.12. But when version is upgraded database and config left the same without changes.
Now I got this situation during import and app not responding after!

[vadim]

Actually I finally got DB, but I also got another problem
No one user, also my old admin account, not able to login and it is not possible to recover and change password.

[girish]

@vadim when you installed traccar, did you install it with Leave user management to the app ? Otherwise, it will use LDAP by default. This flag can only be set at install time. So, start with a fresh installation and select Leave user management to the app at install time.

[vadim]

After a fresh installation with the option "Leave user management to the app" (the same option was used previously), none of the existing users are able to log in. Additionally, it's impossible to change or recover their passwords. I cleared the old database and proceeded with the import. However, after doing so, the system user admin@cloudron.local, who shouldn't be present, remained in the system after the import.

I guess you found this out by checking the users table in traccar ? In Cloudron package, the table name is tc_users . What is the table name of users in your mysql dump?

This was sorted out in support.
