Project JF - Centos 7.1 Install Guide

[mafernando]

Install Steps:

• Download Centos 7.1 Image - obtained here
  • Hopefully, this image mirrors the RHEL 7.1 AMI offered in the AWS marketplace
• Follow steps on this setup guide.
  • Make sure image has at least 1 GB of RAM and 2 CPUs, otherwise you will be stuck in a spinlock when ruby builds
  • See here for instructions on how to install postgres9.4 on Centos7.x
  • Will need to run rpm -Uvh http://yum.postgresql.org/9.4/redhat/rhel-7-x86_64/pgdg-centos94-9.4-1.noarch.rpm and sudo yum update before the yum install commands for posgresql.
  • These are better
    • sudo yum install http://yum.postgresql.org/9.4/redhat/rhel-7-x86_64/pgdg-redhat94-9.4-1.noarch.rpm
    • sudo yum groupinstall "PostgreSQL Database Server 9.4 PGDG"
    • sudo /usr/pgsql-9.4/bin/postgresql94-setup initdb
    • sudo systemctl start postgresql-9.4.service
    • sudo yum -y install postgresql94-devel, this isnt included in group install
    • To Start PGSQL on Boot:
    • sudo systemctl enable postgresql-9.4.service
    • sudo systemctl restart postgresql-9.4.service
  • Definitively: Run
    • rpm -Uvh http://yum.postgresql.org/9.4/redhat/rhel-7-x86_64/pgdg-redhat94-9.4-1.noarch.rpm
    • sudo yum update, and then
  • Need to temporarily su - to root user to be able to edit pg_hba.conf. Run exit after saving edits.
  • gem install pg -v '0.18.2' -- --with-pg-config=/usr/pgsql-9.4/bin/pg_config is all lower case

Notes:

• Should be able to hit the instance using its public ip address if port 3000 inbound is opened in the security policy
• Things work better if you set the environment variables using the DOTENV file, otherwise you may encounter this error.
  • DEVISE_SECRET_KEY
  • SECRET_KEY_BASE
  • DATABASE_URL
  • RAILS_ENV
  • RACK_ENV
• If running from virtualbox, make sure time is up to date. E.g. sudo ntpdate ntp.ubuntu.com Otherwise AWS will not verify your creds.
• Adding GUI to RHEL
• [Adding GNOME GUI to Centos/RHEL EC2 instance](http://www.idevelopment.info/data/AWS/AWS_Tips/AWS_Management/AWS_12.shtml#Add GNOME Desktop and X Window System)
• Rails deployment AWS

Open Questions:

• Should Rbenv be run as root or jellyfish user?
• Should NPM be run as root? There are that require sudo that the jellyfish user doesn't have access to.
  • for Centos, the NPM steps as well as the gulp/bower ones were run as root
  • Maybe incorporate instructions here
  • In the JF Chef cookbook, Kevin had to add jellyfish to the sudo list (under /sudors.d) to execute the node install steps and then remove himself from that list. Not sure if this work around should be accounted for.
• Will need to run rails console proudction to tap into the correct instance, otherwise console will plug into development which is NOT what is needed
