You'll need to know
the Host
Port
Database name
Username
Password
You'll need to make sure your firewall accepts requests from the following IP addresses:
Once you hit Connect you will see your connection details including a full list of tables accessible with this connection.
If you're having trouble connecting, check the error message returned at the top of the Connection page against the table below for a possible fix.
Error snippet
Possible resolution
Can't connect to MYSQL server Connection timed out
Connection Refused
ENOTFOUND
ETIMEDOUT
Check your Host and Port settings and that your database server is open to accept connections from the whitelisted Count IP addresses
Access denied for user
Password authentication failed; please check Username, Password, and Database name settings
Not allowed to connect to MYSQL server
Check the Username with these credentials is authorised to connect to the database from the whitelisted Count IP addresses
Self signed certificate in certificate chain
Check that your database server supports SSL connections. If your database server has self-signed certificates, does not support verifiable certificates, or your host is an IP address you may need to add the Certificate Authority or "trust" the incoming server certificate (see SSL certificate errors section below)
If you see a connection error complaining about "self signed certificates", it's likely that there's an issue verifying the SSL certificates issued by your database server against the host parameter of your sever details. This can happen for several reasons
You are using manually created self signed certificates, in which case it's not possible to verify the identity of your server
The database server does support verifiable certificates (e.g. some Heroku systems)
The certificates are issued by the provider of your managed database server (e.g. Digital Ocean, GCP) and the host parameter is an IP address
If anyone of these is the case, the connection issue can usually be resolved either by
downloading your database server Certificate Authority (CA) file, usually given in PEM format, and uploading to the "Advanced" section of the connection setup
or, activating the "Trust server certificate" in the "Advanced" section of the connection setup
You may be wondering why you're able to connect automatically to clients such as mysql client or other web-based BI tools, but Count may require you to upload the CA certificate.
You should consult your database administrator to confirm that this setting is appropriate for your system.
If another product is able to connect automatically without the above worrying about server certificates, it may be worth checking what SSL mode they are using for communication, and whether this is sufficient for your needs.
In the section of the MySQL documentation, it clarifies that there are 6 modes of SSL support.
By default, Count communicates with your database server by using the most secure method of communication, "verify-full", which provides full protection against eavesdropping and attacks. This method requires full verification of the CA , which may not be possibly if the server does not issue a root certificate, or if the domain of the certificate and the database server host address do not match (as is usually the case where the host parameter is an IP address). In that case, uploading the CA file manually to Count allows the communication to happen safely with the mode "verify-ca", using your uploaded certificate to ensure maximal protection against eavesdropping and MITM attacks.
If you are unable to obtain a copy of your database CA (e.g. some Heroku systems), the only way to initiate encrypted communication with your database is to trust that the certificate sent by the server is correct (SSL mode "require"). This ensures full protection against eavesdropping, but not against attacks. Count will only use this mode of communication if you activate the "Trust server certificate" in the "Advanced" section of the connection setup.
