I have my blockchain network setup up on the IBM blockchain starter plan using the starter kit (https://github.com/sstone1/blockchain-starter-kit)
I'm trying to setup up GitHub passport authentication on my ibmblockchain/composer-rest-server but I cant install the passport-github package on my composer-rest server.
If I ssh into my server I don't have the permission to use npm as I'm the composer user and I don't know where to find the password to change to the root user.
I tried to install the npm package by adding 'npm install -g passport-github' in the deploy_composer_rest_server in the pipeline-DEPLOY.sh file in https://github.com/sstone1/blockchain-starter-kit/blob/master/.bluemix/pipeline-DEPLOY.sh but it still didn't work.
If I look at the logs of my ibmblockchain/composer-rest-server I keep getting the error:
Cannot find module 'passport-github'
Has anyone found a way to get around this or know how to install the 'passport-github' package on the ibmblockchain/composer-rest-server?

If you look at the Google OAuth tutorial in the composer documentation you will see a similar example of running a passport authentication strategy inside a composer-rest-server docker container. These are the specific lines used to build the new container and install the npm module:
FROM hyperledger/composer-rest-server
RUN npm install --production loopback-connector-mongodb passport-google-oauth2 && \
npm cache clean --force && \
ln -s node_modules .node_modules
If you have continuing problems, I would suggesting opening a ticket the IBM Cloud.

I am trying to restart Apache and I get...
ubuntu#ip-172-xx-xx-xx:~$ systemctl restart apache2
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to restart 'apache2.service'.
Authenticating as: Ubuntu (ubuntu)
This is a brand new instance and I never set the ubuntu user password. Is there a default password set on instance creation?
How do I restart apache in AWS Ubuntu?
If you setup a key pair for your instance on creation, then there is no password for the user ubuntu nor is password based login enabled. You must login using your key pair.
To execute commands that require elevated permissions, use sudo in front of your command. The actual command to restart apache2 depends on which Linux distribution and version you are using.
sudo systemctl restart apache2
or
sudo service apache2 restart

Disclaimer: I am a newbie to web development.
I built a program using Python, on Django framework. I am at a point where I feel ready to deploy my site, and make it go live.
After extensive research, I've noticed that every possible path to deployment requires me to use Git.
The problem is that Git is so hard to manipulate on my computer. I have the wrong version (I guess) installed, and my attempts to fix compatibility issue has been a nightmare (Im using Mac 10.7.5, and for some reason cant upgrade to newer MAC El Captain)
My question is this: Is there a way to deploy WITHOUT using Git? Evenmore, is there a way to deploy without the use of version control (I'm the only one building this site).
I just want the easiest path to deployment possible, since I am a complete newbie.
PS Please dont direct me to this link: Is git branches necessary for a single developer?
my questions is about the importance of using Git altogether.
For some platforms, git is required for deployment. Heroku, in particular, requires git for pushing changes to a remote defined on the command heroku create. See here for more details.
In other instances, you have more options, with the caveat that you may spend a lot of time configuring a system to do so and that you may suffer from the inability to have continuous deployment without downtime.
For example, using an Amazon EC2 instance or DigitalOcean, you essentially have a bare-bones Ubuntu installation upon which you control pretty much all facets of configuration, you would be able to send files to your remote instance via SSH or using one of their clients. In this case, you would generally do the following:
Shut down your Django server
Backup your existing application and DB, just in case
Upload the files for your updated application
Run any manage.py commands for migrations and updates
pip install -r requirements.txt to check for updated dependencies
Start your server up again
As stated before, git is not required for deployment, but most Django devs would highly, highly suggest you find the root of the issue you are having with git as it helps to protect against potentially devastating problems down the line and can greatly simplify deployment when your production environment is set up correctly.
EDIT: It's worth noting that git can provide deployment functionality when your deployment environment is set up properly, but deployment often is too complex a task to rely on git alone. A commonly used method is to use Fabric with a custom fabfile to automate deployment tasks. In tandem with git you gain version control, simplified deployment commands, and the ability to run tasks as part of your deployment.

I have been trying to install basic softwares needed for making my linux machine into a development env. I got a machine with RHEL6, however it is not connected to the internet. I am able to connect to the lan and ssh to other machines. I tried to install using yum but failed with the following error.

Prior to this i installed an ngnix web server and tried to do a make but that failed with:
...
checking windows.h presence... no
checking for windows.h... no

make: *** [build] Error 2
Any help is appreciated.
PS: This question is similar to another question How to install C compiler for GCC without Internet connection? (RHEL6)
but i have absolutely no way of getting internet right now.
It looks like your RHEL machine is configured to download packages from RHEL's official repositories, which are only accessible via the Internet.
If you do not have Internet connectivity, you can reconfigure yum, using the configuration files in /etc/yum.repos.d, to download packages from some local RHEL mirror on your LAN.
Either you have to have Internet connectivity, or you need to configure your server to point to a local mirror of RHEL's official repository. Obviously you cannot install something if that "something" is not to be found anywhere. Sadly, software packages cannot just appear, out of thin air, in order for them to be installed.
The only other option for you is to either; download the relevant RPMs on another machine that does have the necessary connectivity, manually copy them over to this machine, and manually install them using the rpm command, and not yum; or obtain DVD-based installation media and install the rpms from the installation DVD.

I am testing apache spark on my aws free tier account following this tutorial. However it creates 2 new instances (1x master and 1x slave) which means I wouldn't be able to run my machines for the whole month...
Question: Is there a way I can install apache spark on one single machine?
thanks
If you are just testing Spark you actually don't need to "install" spark. I do all my Spark development in a local VM running in local mode, but you can do the same thing in AWS with these steps:
Download Spark: http://spark.apache.org/downloads.html I typically go for the "Pre-built for Hadoop 2.6 and later" (don't worry, you don't need Hadoop whatsoever)
scp the tar to your machine, unpack somewhere like /opt or /usr/share
That's it!
You can run the spark shell:
/opt/spark-1.4.1-bin-hadoop2.6/bin/spark-shell
You can run packaged spark applications in local mode:
/opt/spark-1.4.1-bin-hadoop2.6/bin/spark-submit --master local[*] --class com.example.project.class project-1.0.jar
You can start Spark:
/opt/spark-1.4.1-bin-hadoop2.6/sbin/start-all.sh
And hit the Spark UI at port 8080
The solution was easy... follow the instructions to setup apache spark as a standalone server link

I'm looking to deploy a django app on AWS (since I have some credit coupon) and am looking for a good place to read about it - mostly b/c I never used it before. thanks
looking for a good place to read about it
Here you go
I am a developer at BitNami, you may want to take a look at our free Django AMI. It is compatible with the AWS free tier.
2 new tutorials are given
realpython doc
and
Ashok Fernandez blog
The simplest approach is to simply spin up an EC2 instance, install nginx (mysql? and any other dependencies you might have) then follow the steps on the django site: https://code.djangoproject.com/wiki/DjangoAndNginx to deploying it. This basically goes through setting up a script to run "python [your app directory]/manage.py runfcgi host=127.0.0.1 port=8080" and setting up nginx to proxy requests to that port.
Another approach is to simply use a 3rd party tool like http://nudow.com to automate the deployment. For now the initial deployment I believe has to be done manually, however subsequent deployments can be done with one click. (and has other benefits like versioning)
I usually use Nginx on an EC2 instance
If you wish to deploy your Django app ASAP, without scratching your head :
You can use this script that I wrote:
Safely deploy your Django app in less 1 minute!
Instructions
Installing the DeployDjango script
$ wget https://raw.githubusercontent.com/yask123/DeployDjango/master/deploydjango.sh && chmod +x deploydjango.sh
From your Django App’s root directory (Where manage.py file exists).
$ sudo ./deploydjango.sh project_name
Done!
