问题
I'm trying to create a Firebird database in my home directory through Flamerobin however I always get
*** IBPP::SQLException ***
Context: Database::Create
Message: isc_dsql_execute_immediate failed
SQL Message : -902
Unsuccessful execution caused by a system error that precludes successful execution of subsequent statements
Engine Code : 335544344
Engine Message :
I/O error during "open O_CREAT" operation for file "/home/user/test.fdb"
Error while trying to create file
Permission denied
even though the file is chmod 777, the file /etc/firebird/2.5/firebird.conf has been modified so that:
DatabaseAccess = Full
is set to allow access to all files. The service is running:
$ ps ax | grep fireb
3909 ? S 0:00 /usr/sbin/fbguard -daemon -forever -pidfile /var/run/firebird/2.5/fbserver.pid
even though strangely the netstat doesn't find the connection port:
netstat | grep 3050
and returns empty list.
If I connect to an existing database all works, for instance connecting to
/var/lib/firebird/2.5/system/help.fdb
correctly shows tables.
回答1:
I see two possible causes:
You mention that the file is chmod 777, this implies that the file already exists, so creating a new database will fail.
You are trying to create (or connect) to a file in a user folder (I assume yours), through the Firebird server (although the fact no server is running might indicate this isn't the case).
I assume that the Firebird server isn't running under your account (but under the firebird user), and therefore it isn't allowed to access files in your folder.
You need to create (or access) the database in a location where the Firebird user has sufficient access rights, or use a local (embedded) connection (although I am not sure if that is supported by flamerobin.

You must do some things... first, let's see the security stuff...
in the file /etc/firebird/2.5/firebird.conf
section: DatabaseAccess it must be like this:
DatabaseAccess Restrict /the/directory/you/want/to/put/the/database
now, in the file /etc/firebird/2.5/aliases.conf
you put an alias and the directory...
diryouwant = /the/directory/you/want/to/put/the/database/database.fdb
save and restart the firebird service like:
sudo service firebird-2.5"theversionyouhave" restart
you must change the directory owner like this:
sudo chown firebird.firebird /the/directory/you/want/to/put/the/database
and now you can use flamerobin without any trouble...

Check /home/user owner and mode and firebird process owner. I'm pretty sure user which running firebird just do not have access to this directory.
回答4:
I had same problem, as described, trying run firebird 2.5 in a Oracle Linux OS, can't restore any database with gbak, same error message.
After a search, I found an answer saying about permissions on the destination directory and on the temp directory.
My solution: as root:
first re-run firebird installer to grant that are no problems in installation;
after, create specific directory for firebird databases on / (example, /fdb),
move the backup files to this directory;
change owner of entire directory to firebird with this commands
chown firebird /fdb -R
chmod 700 firebird /fdb -R
after this, gbak is normally for me, running it as root.
