1. Reset aliceanderson password example

2. How to "unsource" your bash session
   source .bashrc

A fix to avoid slow yum mirror in anisble lab when a mirror is down and yum slows to a craw or completely fails.

1. Why are YUM updates taking so long!!

• Here is the YUM mirror status: http://mirror-status.centos.org/
• Here is yum.conf file info: https://docs.fedoraproject.org/en-US/Fedora/15/html/Deployment_Guide/sec-Configuring_Yum_and_Yum_Repositories.html
• The default retries before YUM advances to the next mirror is 10 (TEN!!!) retries, let's make that 1: Copy this text into the files directory and name the file "yum.conf"

2. In your home directory, make a new directory called "files"

3. copy /etc/yum.conf to /~/files

4. Edit your new yum.conf file by adding retries=1 to the bottom of the config as shown below.

[main]
cachedir=/var/cache/yum/$basearch/$releasever
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=5
bugtracker_url=http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/bug_report_page.php?category=yum
distroverpkg=centos-release
retries=1

5. Save the file

6. After you have downloaded sl.yml file, modify it to look like this:

 
- hosts: openstack
  remote_user: root
  tasks:
  - name: Look at me adding my first line of devops code! The next line of code updates yum.conf on all my hosts, this is really cool.
    copy: src=/home/centos/files/yum.conf dest=/etc/yum.conf owner=root group=root mode=0644
  - name: Install sl even though I have no idea what sl does... yet.
    yum: name=sl state=installed

Now run the sl.yml playbook and it should go a lot faster.

How to save files from my Openstack Lab to view later

1. First do lab 13 which will set up an account with github

2. Then SSH into your controller and issue these commands

   `mkdir ~/myopenstack``

   cd myopenstack

   yum install git

   git config --global user.name "---Your Name Here---"

   git config --global user.email "[email protected]"

   git config --list

   git init

   touch readme.txt

   vim readme.txt

   This is my test file to see if I can push a file up to gut hub.

   git status

   git add readme.txt

   git commit -m 'This is supposed to add Readme.txt to my repository'

   git add

   CREATE REPOSITORY on github called 'myopenstack'

   git remote add origin https://github.com/YOUR-ACCOUNT-NAME-HERE/myopenstack.git

   git push origin master

   # respond to login
# respond to password

Out of sync? Do this

git remove origin

remote add origin https://github.com/YOUR-ACCOUNT-NAME-HERE/myopenstack.git

git pull origin master

This will sync github with your current directly

git push origin master

Now that you are synced with github, this should work
