Installing Jira Software Server

Standard

Assuming you have downloaded from Atlassian. If not read how to prepare for installs.

Follow prompts and make sure you enable the service option if you want Jira Software to autostart on bootup.

If you installed using sudo it’ll place the app in dir: /opt/atlassian/jira, which is good.

Note these files in case you don’t want it to be installed as a service or if something happens.

Preparing a Server for Atlassian Software

Standard

I’ve been a user of Jira before the kanban “agile” interface and it was still one suite with an agile plugin. I use both Jira Core (“task”) and Jira Software (“agile”). I use Core for task based projects and Software for well software based projects.

I actually use Core for home projects like: my daughters 3rd birthday, remodeling the garage, gardening task like cloning my chili plant or gardenias. I have a project with multiple task and sub-task.

Given: I have an over powered media server running Ubuntu 18.04 and I have a need to track my personal task and projects. And I thought it would be a fun weekend project.

When: I install Atlassian’s Jira Software Server, Jira Core Server, and Confluence Server (I will be also installing Bamboo Server and BitBucket Server at a later time)

Then: I will have access to Jira for any task or project and I can track progress. I will have also learned how to manage and use Jira from another point of view. Not just moving features across and completing them.

Updating Ubuntu 17.10 to 18.04

Standard

If you need to upgrade your Ubuntu to a new release.

Wait a few minutes/hours, you should have upgraded your server.

Creating an image with A Dockerfile

Standard

The Dockerfile

Simply a file or manifest that has all the commands needed to be run to create an image when you run ‘docker build’. You can find more information here: Dockerfile docs

Simple Dockerfile

Just to keep it simple a Dockerfile can be as simple as installing packages after setting up a server and creating some directories. Here’s an example:

Here is a Dockerfile I used for a virtual host apache image:
https://github.com/mfung/alpine_apache2_php7

Commands

Some commands when dealing with building an image:

 

Using Docker-compose

Standard

Commands for docker-compose

You will need a YAML file that contains your stack.

Stack file

A little more complex example: https://gist.github.com/mfung/9b0fd65ccc793c7b1ec44dfb2deb370d

Install & Using Docker (OSX, CoreOS, Docker-CM, Alpine Linux, Docker-Compose)

Standard
I recently decided to consolidate some of my websites onto one server. I also wanted to https (SSL) most if not all my websites. Before I would use CentOS or Ubuntu and Nginx as a reverse proxy with Nginx/Passenger serving my Rails apps and Apache/PHP serving my WordPress/PHP sites. Here’s how I installed docker, docker-cm and started using containers on my production servers.

I’ve known about Docker and I’ve used it indirectly, a Rails app i worked on used it in production but it was abstracted from us software engineers. So I installed Docker-CM on both CentOS, Ubuntu, and Docker on OSX to experiment.

OSX: https://docs.docker.com/docker-for-mac/install/

 

After spinning up some containers and learning some Docker commands.

Docker Commands

 

I started to research minimalist Linux distros for the host OS. I only need to be able to run Docker-CM, maybe a firewall, and some other minimal software on it because the heavy lifting would be done in each of the containers. While doing that I learned about Alpine Linux for the container image. I was using CentOS and Ubuntu images at first and while looking at host images and file sizes I realized I can be more efficient with the containers as well.

Docker Images

REPOSITORY TAG SIZE (MB)
alpine latest 4.15
centos latest 207.0
ubuntu latest 111.0
busybox latest 1.14

Now why I didn’t use BusyBox instead of Alpine. I just found alpine and apk easy and familiar. And their motto is “Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busy box.” I like security, I like lightweight, and I like Linux.

With all this playing around and researching, I found docker-compose and read up on creating a Dockerfile. I also ran across some important images:

postgres:10.1-alpine
nginx:alpine
jrcs/letsencrypt-nginx-proxy-companion
jwilder/docker-gen
WordPress (there are different flavors of alpine, apache, and different versions of PHP)

What I wanted in my ecosystem is Postgres (Phoenix, Rails, and my goto DB), MySQL (for my WordPress sites), Redis, MongoDB + R, Nginx Proxy, Apache Virtual Hosting not just 1 instance of WordPress per container.

Setup Jenkins and BitBucket without plugins

Standard
Standard

This was pretty straight forward since BitBucket has hooks ready for Jenkins.

I usually create 2 Jenkins projects, 1 to build and 1 to deploy.

Jenkins Server

Make sure you have a Jenkins user that can Read Overall and Read Job. I use “Project-based Matrix Authorization Strategy” you can find that under “Configure Global Security”

So I have a user called automated-user and it has Read Overall and Read Job checked. It also has an API Token you will need that you will find here: Jenkins >> Manage Jenkins >> Manage Users >> Select your user, in my case ‘automated-user’ >> Configure >> “Show API Token”. I get eadefe23232121232sdasdfadf as an example.

Build Project

Give the project a name: project-name-build
Source Code Management: Select “Git Repositories” >> Repository URL = https://username@bitbucket.org/username/git-repo.git >> Add credentials & Select it.
Build Triggers: Check, “Trigger builds remotely (e.g., from scripts)” >> Authenticated Token, enter a token SecureRandom.urlsafe_base64 works well for this. Lets say we got this: wtOhS3d4TV1MRX_bVn_lAA

Deploy Project

Source Code Management: Select “Git Repositories” >> Repository URL = https://username@bitbucket.org/username/git-repo.git >> Add credentials & Select it.
Build Triggers: Check, “Build after other projects are built”

BitBucket

Go to: Your Repo >> Settings >> Hooks >> Select Jenkins

Enter: 
Endpoint: http://automated-user:eadefe23232121232sdasdfadf@ci-server-address.com
Project Name: project-name-build
Token: wtOhS3d4TV1MRX_bVn_lAA

Save.

You should be good to go minus some settings you’ll need to configure based on your needs.

Learn how to use top command in linux

Standard

I find myself using this often while debugging errors or trying to figure why a server is slow or unresponsive.

 

Vagrant Boxes / VMWare Fusion / CentOS 7

Standard

Use one found here: http://www.vagrantbox.es you can use one of those to build upon or you can create one.

These steps are if you want to to create a fresh box.
Grab the latest CentOS image here:
http://www.centos.org/download/

I use the minimal image http://ftp.usf.edu/pub/centos/7.0.1406/isos/x86_64/CentOS-7.0-1406-x86_64-Minimal.iso

First you need to create a VM using Fusion.

  1. Select “Install from disc or image” >> Continue
  2. “Use another disc or disc image” >> Find your iso >> Continue
  3. Uncheck “Use Easy Install” make sure “Make your home folder accessible to the virtual machine is unchecked. >> Continue
  4. Click “Customize Settings” >> Rename your vm and place it somewhere safe.

Nginx / Comodo PositiveSSL / CentOS 7

Standard

1. Before you purchase your SSL

Before any purchase of an SSL you’ll need a key file and a csr (Certificate Signing Request).

The certificate registrar is going to ask for the contents of your csr file, just cut and paste whats inside the file into the webform. Make sure you register with the domain name you plan on using. Purchase your SSL, they’ll send your administrator an email validate that. Then wait for an email from Comodo with a zip file.

Within this zip file you’ll receive 4 files:

  • AddTrustExternalCARoot.crt – Root Cert
  • COMODORSAAddTrustCA.crt – Intermediate Cert
  • COMODORSADomainValidationSecureServerCA.crt – Intermediate Cert
  • server_name.crt – Your Positive Cert

2. Prep for installing SSL Cert

3. Installing the SSL Certificate

Now to configure Nginx.

4. Restart Nginx
