Hi Rob Yes, this looks like an SQLAlchemy issue, producing an 'create index' statement which is not compatible with MySQL. I guess line 146 in "~/lib/galaxy/webapps/community/model/migrate/versions/0001_initial_tables.py" is the culprit: Column( "annotation", TEXT, index=True) ) I don't know whether this works, but I would suggest you change that line to: Column( "annotation", TEXT) ) run it again. And then manually add the index by executing CREATE INDEX ix_tool_annotation_association_annotation ON tool_annotation_association (annotation(100)) The problem is: MySQL can only index the first x characters of a BLOB or TEXT. Using the above suggested statement will create an index using the first 100 characters of the name column.

To ease the maintenance of our Dutch National galaxy, we're trying to set up our own toolshed on a system that happens to have a nicely large MySQL database running. We'd like to make it use that database. The setup has been ok, until we started running the toolshed on the MySQL server for the first time, which resulted in the message in the community_webapp.log I copied below. Is this an incompatibility?
