[Lxr-general] My configuration complications

[Shahbaz K. <sha...@gm...>]

I have switched from version 0.3 to version 0.9.5 after a continuous
failure in configuration.

Currently, after all configurations I do http://localhost/source, it
dumps the source.pl script from lxr directory as text! I cannot not
figure out how to run the various tests that come with lxr.

In the lxr.conf do I need to set username, password if I use initdb_mysql?
I also checked my /etc/passwd and did not find any lxr user so is this
user local to mysql server?
lxr database in mysql has not been populated even after generating the
indexes and genxref command.

I wish if someone could write a decent howto or guide on such a useful
tool so that it becomes useful for newbies like me!

Did you read the INSTALL file carefully enough? I found it sufficient to
install lxr-0.9.5.

Your problem happens when the Apache server doesn't run perl to execute
the perl script, but dumps the script instead. Make sure followed all
instructions.

Did you read the comments in templates/lxr.conf?

                # The DBI identifier for the database to use
                # For mysql, the format is dbi:mysql:dbname=<name>
                # for Postgres, it is dbi:Pg:dbname=<name>
                # for Oracle, it is
dbi:Oracle:host=localhost;sid=DEVMMS;port=1521
                'dbname' => 'dbi:mysql:dbname=lxr',

                # If you need to specify the username or password for
the database connection,
                # uncomment the following two lines
                #  'dbpass'             => 'foo',
                #  'dbuser'             => 'lxr',

Take your time to read the instruction files and even the source
files... This is always helpful at the end.

My advise: you should first solve your Apache / Perl issue.

Good luck!

This is an important step.  What exact LXR version do you use
(released 0.9.x or from CVS?) and what exact kind of web server
(Apache 1.x? Apache 2.x?) are you using?

>From the INSTALL file:

|1;
|- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

For me, it worked by just installing the appropriate Debian packages
(libapache2-mod-perl2 and apache2) and enabling the module (link it
into /etc/apache2/mods-enabled from mods-availabl).

Either the spam filter ate it, or it simply didn't find its way to the
mailing list.

Please resend--this version was missing the mentioned attachments.

You can use any existing user, but in general, it's wise to separate
stuff that's, well, separate. So better create a fresh user for LXR.

> > Does mysql server have local users?

It does. Usually, all the SQL servers have their own user management
that's not at all related to system users.

> > Is lxr linux user of sqlserver user?

I don't understand this question.

At most, I see these users being in the game:

  * One (system) user that Apache is using. This usually is "www",
    "apache", "www-data" or something like that, rarely "root" is
    uses.
  * One (system) user that's owning the LXR related files. The Apache
    web server's user (www, apache, www-data, ... as above) must have
    read access to the LXR files. Using the same user is the simple
    approach, but depending on your setup, you may want some real user
    to be able to update LXR or change its configuration, so it may be
    a regular user accoung.
  * A (system) user that the database server is using, usually named
    like the RDBMS system (eg. "postgres", "oracle", ...)  You
    possibly need to have access to this user to create the next one,
    a DB-specific user for use with LXR.
  * A (DB-specific) LXR user, which lifes entirely inside the DB,
    including its password, access management etc. Account data for
    this user is usually placed into the lxr.conf file.

> > My database is empty even after generating the indexes

That means that either there was nothing to index, or that some error
happened. Tough you didn't post error messages (and the config
attachments aren't in this resent email), we this is a guess--at best.

> > I do not use CVS so should I comment out its requirements? Like CVS bin

LXR is a system to present source code with the help of a web browser.
You need to give LXR the source code you want to present. How did you
do that? (Your lxr.conf file would probably tell us...)

There are several ways:

  * Offer a Bitkeeper repository to LXR.
  * Offer a CVS repository to LXR.
  * Offer a GIT repository to LXR.
  * Offer plain files to LXR (eg. extract tarballs of the project:
	mkdir /data/sources/linux-0.01 &&  ( cd /data/sources/linux-0.01  && tar x=
jf /path/to/linux-0.01.tar.bz2  )
	mkdir /data/sources/linux-1.0.0 && ( cd /data/sources/linux-1.0.0 && tar x=
jf /path/to/linux-1.0.0.tar.bz2 )
	mkdir /data/sources/linux-2.0.0 && ( cd /data/sources/linux-2.0.0 && tar x=
jf /path/to/linux-2.0.0.tar.bz2 )
	mkdir /data/sources/linux-2.6.1 && ( cd /data/sources/linux-2.6.1 && tar x=
jf /path/to/linux-2.6.1.tar.bz2 )
    )

Without sources, nothing will be indexed, because there's nothing to
index.

> > I have no idea how to install the test units! What to do?

Ignore it.  It's mostly used to test LXR after hacking it.

Apache2? Apache1? httpd.conf?  Thses handler options have to be set
for the <Location>:

    SetHandler perl-script
    PerlHandler Apache::Registry
    Options +ExecCGI

ISTR that this should be fixed in the CVS version of LXR.

and lxr.

Thought about offering somebody login data to the machine to install
it together with you in a screen -x session?

Mr Jan-Benedict Glaw

Its so sweet of you to look at all the configuration. Its always a
pleasure to know people like you are out there to help such newbies
like me.

I will work on your hints and let you know about the conclusions. I
should succeed now at least!

Thak you.
