I don't use Apache much, but I found this on a Google search. Running migrations from the terminal uses the current logged in user (unless one uses sudo, which I wouldn't recommend). Unlike other servers, it seems that Apache runs not with the currently logged in user, but it's own user. So the database can be read, but can't be written to because of permissions. See if this helps: https://stackoverflow.com/questions/17641993/operationalerror-attempt-to-write-a-readonly-database-in-ubuntu-server
