[Qt-interest] Deploying application issue

[Robert Escott]

I'm not sure if I understand what you are trying to do. I know you're trying to install your application on various other machines but you say that the program must be able to run without MySQL server installed. This could mean a couple of different things.


1) If you mean that you only want one MySQL server to be installed and all other machines must use this central database, then you need to make sure that the application and the driver files are installed on each of the other machines. From what I've seen in your emails, it looks like you've done this correctly. What you need to do now is to get them to connect to your central server. This turns out to be a networking issue, not a Qt one. You must make sure that you specify the database server's IP (or domain name) as the host name, the user name and the password, and then you must also make sure that you get the port correct. You must make sure that, on all the computers that must use your application as well as the server, that the port is not being blocked by a firewall. The default port for MySQL is 3306 but you can change this in the server settings.

2) If you mean that you are only allowed to install the MySQL server on one central computer but want to use your application on many others without connecting to the MySQL server, you can't. The libmysql.dll and qsqlmysql.dll files are only for communicating to a MySQL database. They do not do any data storage themselves.

Robert

    It could be that there is no mysqlserver on your localhost(10060), and
    therefore your application is unable to connect to a MySql database.

    But, there seem to be possibilities to set the host name and port for a
    database connection:
