mmi orr migration to xdomes vm

MMI ORR migration to xdomes VM

Completion planned for April 1, 2020.

2020-03-26 status

All core pieces are already set up on xdomes but with temporary URL-related settings so the system is visible at https://xdomes.tamucc.edu/mmisw.org/ont/ for testing purposes.

NOTE: Limited VPN access may cause extra delays with this task.

Cutover steps

• Final Mongo DB and ontology files transfer (Carlos)
• Repopulate triple store (Carlos)
• Basic functionality tests against https://xdomes.tamucc.edu/mmisw.org/ont/

---

• Set virtual host on xdomes for mmisw.org (Felimon / TAMUCC IT)

  What's basically needed is something like the following:

  <VirtualHost mmisw.org:443>
      DocumentRoot "/var/www/html/mmisw.org"
      ProxyPass        /ont    http://localhost:39090/ont
      ProxyPassReverse /ont    http://localhost:39090/ont
      ProxyPass        /sparql http://localhost:30035/repositories/mmiorr
      ProxyPassReverse /sparql http://localhost:30035/repositories/mmiorr
      Alias /ontapi    /var/www/html/mmisw.org/ontapi
      Alias /orrdoc    /var/www/html/mmisw.org/orrdoc
      # Carlos can be take care of further adjustments here.
  
      # TAMUCC IT please take care of certificate-related settings, etc.
      # ...
  </VirtualHost>
  

• Remove the temporary "MMI ORR" settings in /etc/httpd/conf.d/ssl-vhosts.conf.

---

• Apply IP cutover with domain name provider (John)

---

• Documentation and webhook for doc update https://mmisw.org/orrdoc/

  • almost there, for now visible at https://xdomes.tamucc.edu/mmisw.org/orrdoc/
  • supporting software in place

• API DOC: https://mmisw.org/ontapi/

  • almost there, for now visible at https://xdomes.tamucc.edu/mmisw.org/ontapi/

• CF vocabulary "watchdog"

  • almost there, supporting software in place and crontab ready to be enabled

• CF browser https://mmisw.org/cfsn/

  • almost there, for now visible at https://xdomes.tamucc.edu/mmisw.org/cfsn/

---

• Tests against mmisw.org as IP cutover propagates (All)

  • https://mmisw.org/ont
  • https://mmisw.org/ont/sparql
  • https://mmisw.org/orrdoc/
  • https://mmisw.org/ontapi/
  • https://mmisw.org/cfsn/
  • https://mmisw.org/experimental/vbrowser/

• Declare victory

Additional notes

Software installed

During the migration process:

• installed java, required to run the CF watchdog program

  $ sudo yum install java-1.8.0-openjdk-devel
  
  $ java -version
  openjdk version "1.8.0_242"
  

• installed mkdocs, required to generate MMI ORR documentation

  $ sudo yum install mkdocs
  
  $ mkdocs --version
  mkdocs, version 0.14.0
  

Migration scripts

• export-mongo-collections.sh to export mongo data on previous mmisw machine:

  for c in organizations users ontologies; do
    echo "importing $c ..."
    mongoexport --collection=$c --db=orr-ont --out=$c.json
  done
  

• import-mongo-collections.sh to import mongo data on xdomes machine:

  for c in organizations users ontologies; do
    echo "importing $c ..."
    mongoimport --collection=$c --db=orr-ont --mode=upsert --file=$c.json
  done
  

  Note that this script, along with the *.json files are first docker cp-ed to the mmisw-mongo container, where the script is then run.

mmisw.org directory

• Located at /var/www/html/mmisw.org, this will be the DocumentRoot for the mmisw.org VirtualHost

• Fixed permission issue with contents under experimental with: chcon -R unconfined_u:object_r:httpd_sys_content_t:s0 experimental. See https://cwiki.apache.org/confluence/display/HTTPD/13PermissionDenied.
