set timezone for tomcat - timezone

I've got issue with this file .openshift/action_hooks/pre_start, the text is export JAVA_OPTS_EXT="-Duser.timezone=Europe/Stockholm" but new timezone does't work. It's not changing.
Any help, with this?
Thanks

You should use the "rhc env set" command to set the JAVA_OPTS_EXT environment variable like this:
rhc env-set JAVA_OPTS_EXT="-Duser.timezone=Europe/Stockholm" --app <appname>
But I ultimately agree with Jon that you should avoid using that timezone at all.

how to add environment variable in linux for rails app?

i need to set an environment variable for the rails app to use
SECRET_KEY_BASE=9941144eb255ff0ffecasdlkjqweqwelkjasdlkjasd
the config settings for production is as shown below
# Do not keep production secrets in the repository,
# instead read values from the environment.
production:
secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>
how can i set the environment variable using the linux command
export VARNAME="my value"
I tried to set the variable but looks like it needs to be for the right user. Sorry i am not an expert in linux.
I appreciate any help! Thanks!
export VARNAME="my value"
Well the above works for your current terminal session. After this command, all the subsequent commands can access this variable. Try running this:
echo $VARNAME
It will print the value my value in the console. If you want this behaviour to be persisted, you need to place the export command in your OS' config file (~/.bashrc in case of Ubuntu).
After editing this file, either restart your terminal, or run this:
source ~/.bashrc
This will reload the file in your current terminal session. Alternatively, you can try running your Rails server (or a rake command) as follows:
VARNAME="my value" rails s
For your local development I suggest you to use dotenv (https://github.com/bkeepers/dotenv) or figaro (https://github.com/laserlemon/figaro) and follow the README you find in the gem itself. This gives you much more flexibility than using directly environment variables because you set them only for this specific project and each project can have different of them.
You need to have either a .env file or a application.yml file where you will define your environment variables.
Remember to not commit or push this file to your repository because it contains sensible information!
When you will deploy to production you can use real environment variables or use admin panel control (on Heroku for example)

Environmental variables in /etc/environment are not accessible by rails

I have been trying to deploy a rails project and it requires some environmental variables so I did some research and it turns out the best place to add them is inside /etc/environment which i did so and then sourced the file.
I now can get/access the environmental variables by running echo $variablename; however the rails application can still not see these environmental variables?
/etc/environment is not automatically sourced by all shells in all login contexts. To get the settings into the rails environment, there are a couple options. The easiest is probably to modify (or create) the .bashrc (assuming the rails user's shell is bash, which is the Ubuntu default shell) in the home directory of the user rails runs as and add the following line:
source /etc/environment
If you want the variables to be available to all users on the system, you can create a file called /etc/profile.d/environment.sh (or something similar) and add the above line to that.
For either solution, log in again as the rails user and verify the environment.
You might want to use this gem for env variables:

Ruby on Rails environment variable for development environment

Just a quick question to which I couldn't find an answer on stackoverflow.
If it is easy to have environment variable for staging and production (on heroku for example), how can I set environment variable for my localhost (development environment)? (I am on a mac)
As of today I hardcode my api credential for development environment and I don't feel comfortable with that.
Thanks !
Use dotenv is intended to be used in development:
Add your application configuration to your .env file in the root of your project.
S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE
You may also add export in front of each line so you can source the file in bash.
in .bashrc
export S3_BUCKET=YOURS3BUCKET
export SECRET_KEY=YOURSECRETKEYGOESHERE
Then access in rails app ENV['S3_BUCKET']
Environment variables are best placed in your .bash_profile file which lives in your home directory on the Mac: /Users/you/.bash_profile. Open that file and add something like this to the end of it:
export MY_ENV_VAR=my_env_value
or
export MY_ENV_VAR="a string with spaces in it"
export is a shell command that sets environment variables. Your .bash_profile is a bash script that runs every time you open a new shell session (open a terminal window) and therefore your export commands will run and set the env vars.
Then they will be available in the ENV constant when you're in Ruby.
Edit /Users/your_user_name/.bash_profile and add there:
export RAILS_ENV=development

How to see the value of rails environment variables on production server

I'm currently trying to troubleshoot an issue on a production server for a rails app and have realised I don't know how to view the values of certain environment variables being used by the application.
I'm using figaro to store things such as the devise secret key but need to make sure that the value is correct for the instance of my app that is running.
I'm looking for something along the lines of
echo $MY_DEVISE_KEY
I understand that I can access figaro's variables from inside the rails console but would that be a different instance?
Also, I'm using ubuntu server and nginx to serve my app.
Thanks in advance
Have you tried
printenv
and you can search for a specific env variable like
printenv | grep foo

Rails Env Issue

So the other day I was trying to replicate some of the tests that were being ran by circleci and before some of the commands I called:
export RAILS_ENV=test
export RACK_ENV=test
and now I guess the problem is that I seem to be stuck in test?
Also,
I've tried executing those same commands except with each of the vars set to development, yet to no avail.
Any ideas?
try 'unsetting' those env variables.
export RAILS_ENV=
export RACK_ENV=
or try restarting the server to set them back to default.
