I am creating a php web-app/web-service with mysql database access that should become opensource.

Currently i have to put 2 php variable $dbuser=... and $dbpassword=... into the script to connect to the osdn database

so everbody who gets the source code for the script will know my osdn-username/osdn password.

what is the osdn prefered way to handle this issue?

Since i donot have the permission to create database users like

CREATE USER 'fdRatingUser'@'somehost.osdn.jp' IDENTIFIED BY '*******'; GRANT SELECT ON fdappratingserv.knownApp TO 'fdRatingUser'@'somehost.osdn.jp'

i cannot add an additional database user that does not have my osdn-login credentials.

my proposal to solve this issue.

every project gets two database users: one project-db-admin user that can create/modify tables and one aditional project-db-webuser that can receive grants from the project-db-admin user.

It would be nice if this issue is documented in https://osdn.jp/projects/docs-en/wiki/ProjectWebDB_FAQ

Note: i cannot assign this ticket to a component because the component names are in japanese and i donot speak japanese

You would set correct permission to these kind of file to hide (can not read ) from non project members.

For example for project 'foo', target file 'bar'

• http daemon running on project web server will execute the script as user: foo.p, group: foo, so web script should be read by user foo.p or group foo. The script file should have user foo.p read permission or group foo read permission.
• The file owner can read and write the file.
• Other people should not be able to read the file 'bar'.

In this stuation you can change permission the filr bar as bellow:

 chmod 640 bar
