Configure sinedon.cfg¶

Sinedon is an object relational mapping library designed to interact with the Leginon and Appion databases.

For older versions of Appion and Leginon (pre-2.2), please use the following instructions:
Instructions for Appion and Leginon versions prior to 2.2

The order in which Leginon/Appion looks for sinedon.cfg¶

1. individual user home directory
2. $PYTHONSITEPKG/sinedon
    
   Note: You can discover the $PYTHONSITEPKG path by starting python:
   

   python
   import sys
   sys.path
   

   
   The first path to site-packages should hold the config file.
    
3. /etc/myami (on Unix)

Locate the search directories and the currently loaded cfg files by running the following python script in $PYTHONSITEPKG/leginon¶

configcheck.py

Create a sinedon.cfg for all users¶

• An example configuration file is available at:
  myami/sinedon/examples/sinedon.cfg

• Configurations for all users should be placed at the following path:
  /etc/myami/sinedon.cfg

• Modify sinedon.cfg to look like the following example. Set the host, db, user, and passwd to match the databases created during your Database Server setup. Note that the user here is the MySQL user Leginon uses to communicate with the database for all Leginon users. For an Appion or Leginon installation that uses Project database, set the following:
  

  [global]
  #host: your_database_host
  host: localhost
  user: usr_object
  passwd:
  
  [projectdata]
  db: projectdb
  
  [leginondata]
  db: leginondb
  

Note: If you are a developer, and you need to use sinedon.cfg settings that are different from the global settings, you may create your own sinedon.cfg file and place it in your home directory. This version will override the global version located in the site packages directory.

Appion database is set dynamically through project database. No module entry is needed here.
