JDBC MySQL connection using Unix Socket

Question

I am using MySQL using the --skip-networking option on Linux.

Trying to connect my J2EE based application (using servlets) to the MySQL database using JDBC.

Answer 1

If you want to use UNIX sockets with the Mysql JDBC Connector/J you need to provide a socketFactory.

jdbc:mysql:///?user=test&password=test&socketFactory=&=/tmp/mysql.sock

So this will vary with the implementation you use. By default, Mysql does not ship with any implementation for that, just provides an example for such a factory in it's source-code.

There is an existing UNIX socket Java library named junixsocket which also has such a socketFactory class implementation. An example is outlined in Connecting to a MySQL database via Unix Domain Sockets which is part of their documentation.
