1. In the [trac] section of the conf/trac.ini file I needed to add the following:

database = mysql://trac:trac@localhost:3306/trac
database_charset = latin1

1.1 Reload the apache server

/etc/rc.d/init.d/httpd restart

2. trac-admin project-dir upgrade

I get an error there about a table, then

3. In mysql

drop table milestone;

create table milestone (
name varchar(255) primary key,
due int(11) null default null,
completed int(11) null default null,
started int(11) null default null,
description text null default null);

INSERT INTO milestone VALUES (‘milestone1′,0,0,0,NULL);
INSERT INTO milestone VALUES (‘milestone2′,0,0,0,NULL);
INSERT INTO milestone VALUES (‘milestone3′,0,0,0,NULL);
INSERT INTO milestone VALUES (‘milestone4′,0,0,0,NULL);

4. Try again the upgrade…
