Directory layout

Mireka has a single home directory, MIREKA_HOME, which contains almost everything related to it: configuration, mails, log, Java code. The actual data may reside on some other part of the file hierarcy, but even then, the home directory contains a file system link to the actual place of the data. For example in case of the Ubuntu deb installation, MIREKA_HOME is /var/lib/mireka, which contains a soft link named log, which points to the /var/log/mireka directory, which in turn contains the log files.

The place of MIREKA_HOME depends on your system and installation method:

If you installed Mireka by extracting a binary distribution archive then the home directory is the one into which you extracted the archive. For example /opt/mireka.
If you installed the deb package then the home directory is /var/lib/mireka.

See the installation pages for more information.
