Troubleshooting MySQL



Connecting to MySQL using a private certificate

1.Create SSL keys as described in Creating SSL Certs

2.Create a client certificate.

2.1.openssl pkcs12 -export -in client-cert.pem -inkey client-key.pem -certfile cacert.pem -out client.pfx

3.Grant privileges to the user as described in Grant Syntax

3.1.GRANT ALL PRIVILEGES ON test.* TO 'root'@'localhost' IDENTIFIED BY 'goodsecret' REQUIRE SSL;

4.Run certmgr.msc and import the client certificate in the user store

5.In the advanced settings or your MySQL data source set the following values

5.1.Certificate Store Location: CurrentUser

5.2.SSL Mode: Required


Error when edit entry "MySql.Data.MySqlClient.MySqlException (0x80004005): Packets larger than max_allowed_packet are not allowed."

When you have that type of error when you try to edit or add a new entry on a MySQL database the problem is because your Advanced Setting had been modified.


The resolution is to Edit your database, Select the Advanced tab and go to Advanced Settings.
