Deploying the web app

The instructions below are for installing the web application on a CentOS or RedHat Linux server.

Install dependencies

Install core server dependencies

sudo yum update
sudo yum install httpd mod_proxy mod_ssl -y
sudo yum install openssl -y
sudo yum install git -y

Install node

Install Node via NodeSource

curl --silent --location https://rpm.nodesource.com/setup_6.x | sudo bash -
sudo yum -y install nodejs
node -e "console.log('Running Node.js ' + process.version)"

Install yarn

Yarn is the primary package manager for the web app. Instructions copied from here

sudo wget https://dl.yarnpkg.com/rpm/yarn.repo -O /etc/yum.repos.d/yarn.repo
sudo yum install yarn

Add Apache VirtualHost entry

Add a VirtualHost entry in /etc/httpd/conf/httpd.conf. The web application uses mod_proxy to proxy requests to a Node application. The Location should match the PUBLIC_URL environment variable.

<VirtualHost *:80>
 ServerName localhost
 DocumentRoot /var/www/html
 ProxyRequests Off

 <Proxy *>
  Order deny,allow
  Allow from all
 </Proxy>

 <Location /talentmap/>
  ProxyPass http://localhost:3000/talentmap/
  ProxyPassReverse http://localhost:3000/talentmap/
 </Location>
</VirtualHost>

It is recommended to add the following to /etc/httpd/conf/httpd.conf to enable the compression of files served by Apache

<IfModule mod_deflate.c>
    SetOutputFilter DEFLATE
</IfModule>

Clone repository

Use git to clone the web app repository

git clone https://github.com/18F/State-TalentMAP.git
cd State-TalentMAP/

Source environment variables

Environment variables are documented here

source setup_environment.sh

Build web app

Build the application

yarn install
yarn run build

Copy files

Copy files from the build directory to the root Apache directory

sudo cp -r build/* /var/www/html/ -v

Start Node server

There is a simple Node + Express application that serves the front end and needs to run as a background process. NOTE - you may need to run which nohup to get the correct path.

/usr/bin/nohup node server.js &

Restart Apache

sudo apachectl restart
