No data in rails 3 access.log - ruby-on-rails

One of the log files that i used regularly on my last server was the rails access.log
On our new host the file isn't supplying any data. I did a search and couldn't find any reference to the file. I'm wondering if needs to be configured and/or whether there are specific ownership/permission settings on the file that need to be in place.
Thanks for your help.

Access.log is usually written by the web server, not Rails. Check the apache or nginx or whatever config to find out where it's writing it. My guess is you're used to it being configured to be written in the same place as your rails logs, but now it isn't.

How to display log for Rails application?

I have a rails app and I would like to display the log in the app itself. This will allow administrators to see what changes were recently made without entering the console and using the file with the logs. All logs will be displayed in the application administration. How is it possible to implement and what kind of gems do I need to use?
You don't need a Gem.
Add a controller, read the logfiles and render the output in HTML.
Probably need to limit the number of lines you read. Also there might be different log files to chose from.
I don't think this is a good idea though. Log files are for finding errors and you should not need them in your day to day work, unless you manage ther server.
Also they might contain sensitive data (CC Numbers, Pwds, ...) and it might get complicated when you use multiple servers with local disks.
Probably better to look at dedicated tools for this and handle logs outside of your application.
Assuming that you have git associated with your application or git bash installed in your system.
For displaying log information for the development mode, migrate to your application folder in your console/terminal and type tail -f log/development.log

typo3 website move to other domain - need help step by step

I just got a typo3 website and need to transfer to an other domain.
Is it enough to copy all the folders (except typo3temp?) to the new place?
First I just changed baseurl in ts but it didn't do anything..
Should I do anything with the database when it still on the same server?
In case your question is about "cloning" a complete TYPO3-system an rsync/copy of the whole folder (yes including typo3temp) is the best idea, as this works on all versions, everything else (like excluding typo3temp) depends a whole lot on your TYPO3 expertise to resolve. The database needs to be copied as well. If you need to change db-name or db-credentials on the new system you need to change them in
typo3conf/LocalConfiguration.php
As soon as you have done this Install Tool and Backend should work: At first try the Install Tool:
https://my.new.domain/typo3/install/
If that doesn't work your problem is with the webserver configuration or dns.
If that works (and the reports there show no errors), try the Backend:
https://my.new.domain/typo3/
In case your question is about which changes are necessary to your TYPO3-installation if domain changes and the web server itself is configured correctly, then there are probably two things you need to change, in order to make the frontend work (although both cases might be omitted, depending on your configuration):
sys_template record, if any of those use absRefPrefix or baseurl. If you have access to the MySQL-Database a
SELECT pid FROM sys_template WHERE config LIKE "%baseurl%" OR "%absRefPrefix";
might help finding the template, however these template configuration might also be stored in files (typically in fileadmin/templates/**)
sys_domain records, a MySQL
SELECT pid FROM sys_domain;
might uncover where those are stored
However these changes are only necessary to enable the frontend to work.
Add a domain record in the backend. And while you don't need the content of the typo3temp folder, make sure the folder actually exists.
When you go to the new domain name in your browser, what happens?
Do you get redirected to the old domain? If so, maybe there is an .htaccess redirect happening.
Do you get to the new domain, but if you click on a link end up on the old one?
Do you get an error? If so, what is the error?
Does something else happen?

Where do I put the files I want to be displayed on my webpage on my webhost?

So I just finished the railstutorial.org twitter clone example and I want to put it online with my web hosting provider bluehost. Right now all I have is a file called sample_app with all of the rails stuff in it. And it works fine when I visit it on localhost:3000.
So I go to my bluehost file manager and there are 9 different folders, like public_html, public_ftp, rails_apps, www, tmp, access_logs, ect. Ive uploaded sample_app into this overall directory and into the public_html directory itself. But when I visit my website it just displays the html in a default.html file in the public_html directory.
What exactly is telling my hosting service to use public_html/default.html of any of the hundereds of different files and folders that are in other places on my server space? How do I find this thing and tell it to instead use sample_app or public_html/sample_app and then process everything in that to display my rails application?
Ive tried using bluehost support and they emailed me and said this would be accomplished by creating a symlink which links ~/rails_apps/NinetyNine/public to ~/public_html. I have no idea how to do this and the guides I find online all tell me to enter a series of commands. I dont know whether to do this in a terminal on my ubuntu system or some command prompt that bluehost provides. If it is at a terminal on my system which directory should I be in? any attempts I have made on my system have resulted in a no such file or directory error. When I asked bluehost to explain this they said that this was outside of the scope of their support and had to do with web development not hosting. It struck me as odd that they were unwilling to explain their own response to my problem but whatever.
If anyone of you could help me or point me in the right direction I would very much appreciate it. Thank you
What is telling my hosting service to use public_html/default.html ?
That would be a setting the web server configuration, probably Apache.
In Apache's case, the public_html directory is usually enabled with the
UserDir directive.
The default.html, is also an Apache configuration, DirectoryIndex.
Answering these because you asked: but typically, the global Apache configuration
is maintained by your provider (though you usually have some means to customize
parts of it).
Create the symlink from public_html to
They like gave you a command like (maybe not exactly)
$ ln -s ~/rails_apps/NinetyNine/public public_html
That is something that is intended to be run on your webhost, from a command prompt,
at the top of your home directory.
Look for docs on bluehost for finding out how to get SSH shell access.
That's where you'll enter the command.
More generally, however, you want to make sure you read the docs on how your
provider wants you to upload applications. Bluehost seems to have very nice
docs here:
https://my.bluehost.com/cgi/help/rails
Why your hosting provided said it was out of scope.
You're a beginner, and that's officially OK. Welcome!
But if you asked them a question like "Do I enter these commands on my computer
or yours", they are definitely going to politely respond that this out of scope;
meaning -- "We can't hand-hold you through this". If you ran a gas station and
someone asked you how to use the pump, you'd tell them. But if they then asked
"OK but do I put the gas in my car or yours?" you'd be reluctant to answer, because
there's some fundamental missing.
So how do I get more pointers, directions on this stuff?
Lots of approaches. By the far the best is to do as much stuff as you can on
your own computer. In your case, you could easily set up your own Apache
(Macs and Linux frequently ship with it - readily installable on Windows), and
that would clear up a lot of the conceptual issues.
Good luck!

How to upgrade mantis bug tracker database online?

Your database has not been created yet. Please create the database, then install the tables and data using the information above before proceeding.
Use a ftp/sftp/scp app like WinSCP to examine your directory.
There's usually a readme file in the directory.
Read it and do what it says. It'll likely say to run a script, visit an admin page (and then remove it when you're done), etc.. Or it may say to create your database, and enter the relevant info (hostname, directory, userid/pwd) into a .config file or something.
Oh, and you probably need to have a database created on the host before you do this. Sites like dreamhost and pair have control panels where you create the database, and give the admin/dba userid/passwords. Then it comes back with the server host name/directory where you will point your config to.

Rabbitmq erlang client build failed due to file paths problems?

I have been able to build rabbitmq server on ubuntu linux. It came already prepackaged and on making, it is able to start as a service. When i got the client source, i failed to make because it appeared like it needed a folder called ./deps/rabbitmq-server. Analysing the code, i find that the author of the client was accessing the same header files as are found in the server, using include_lib("path to rabbit.hrl e.t.c") in his header file called "amqp_client.hrl". I then decided to add rabbitmq_server in the lib dir of erlang so as its paths are automatically added on start up of the vm. But still this didnot help. There is also another folder which the client references called "rabbit_common" for an include folder he assumes would contain all the .hrl files there. Please assist me in building both the client and server on my ubuntu server, for testing.
Also, if anyone has used RabbitMQ server for IMs, please provide some benchmarks and/or your findings on its throughput, speed and number of users. How can it be compared to ejabberd?. How can one create AJAX/Jquery/Javascript clients for Web functionality?
thanks
I hope you had made some progress as far as RabbitMQ and ejabberd are concerned.
Below is a link to an interesting discussion that might be of help.
