Documentation change requests

[dwk2]

Documentation change requests from an ISLE install test on December 19, 2017, on a new vm:

• CentOS Linux release 7.4.1708 (Core)

This section of documentation tweaks is from this URL:

• https://islandora-collaboration-group.github.io/ISLE/1_system_process_overview/1_4_testing/host_server_setup_centos/

1. DOC: adduser islandora (with password isle2017)
   CORRECTION: must also state how to set password!
   Existing text: adduser islandora (with password isle2017)
   add code format:
   adduser islandora
   passwd islandora
   isle2017

2. DOC: Create Docker group groupadd docker
   RESULT: groupadd: group 'docker' already exists

3. DOC: Add islandora user to wheel grop sudo usermod -aG wheel islandora
   TYPO: grop = group, right?

4. DOC: Exit out of the ssh session from the host server as the root user and shell back in as islandora
   SUGGESTION: Break this into two statements:
   Exit out of the ssh session from the host server as the root user
   exit
   SSH into host server as
   islandora

5. SUGGESTION: At very extreme end of "1.4. -Testing - Host Server Build - Centos" (and the other flavors, do this too), put an instruction (and hyperlink) to return to the "1.4. -Testing - Alpha Quickstart Guide"

https://islandora-collaboration-group.github.io/ISLE/1_system_process_overview/1_4_testing/alpha_quickstart/

6. DOC: The instruction that follows is confusing, as the quickstart guide never says when to run this command, only when not to run it.
   DO NOT RUN docker-compose up -d during the initial install process
   RESULT: initially, while counter-intuitive, I opted to not run any containers! That's not the result we want from that warning message above.

7. DOC: docker pull islandoracollabgroup/isle-mysql
   RESULT: failed to register layer: ApplyLayer exit status 1 stdout: stderr: write /usr/share/perl/5.24.1/Locale/Codes/Language_Codes.pm: no space left on device

8. DOC: docker pull islandoracollabgroup/isle-fedora
   RESULT: failed to register layer: ApplyLayer exit status 1 stdout: stderr: write /usr/share/perl/5.24.1/Locale/Codes/Language_Codes.pm: no space left on device

9. DOC: docker pull islandoracollabgroup/isle-apache
   RESULT: failed to register layer: ApplyLayer exit status 1 stdout: stderr: write /usr/lib/jvm/java-8-oracle/jre/lib/amd64/libjfxwebkit.so: no space left on device

NOTE: Discovered flaw in our (Williams) server setup. requested that our mount be repartition to be "/opt" instead of "/opt/isle". This will prevent running out of space on "/opt".

Closing this issue. I added documentation and pull requests for PRs 89-93 to cover these updates. I created a new issue #94 that contains the bugs that Gavin will need to fix in the scripts.
