**Step:4**   RESTART APACHE

# SETUP APACHE ON UBUNTU

**Enable these after installing apache2**

       sudo a2enmod rewrite
       sudo a2enmod proxy
       sudo a2enmod proxy_http
       sudo a2enmod proxy_balancer

**Paste this to /etc/apache2/sites-available/000-default.conf**

       <VirtualHost *:80>
            ServerName  livec.outgrow.local
            ServerAlias live.outgrow.local

            RewriteEngine On
            RewriteCond %{HTTP:Upgrade} =websocket
            RewriteRule /(.*)           ws://localhost:4444/$1 [P,L]
            RewriteCond %{HTTP:Upgrade} !=websocket
            RewriteRule /(.*)           http://localhost:4444/$1 [P,L]

            ProxyPass / http://localhost:4444/
            ProxyPassReverse / http://localhost:4444/
      </VirtualHost>
      <VirtualHost *:80>

            ServerName  app.outgrow.local
            ServerAlias *.outgrow.local

            RewriteEngine On
            RewriteCond %{HTTP:Upgrade} =websocket
            RewriteRule /(.*)           ws://localhost:5555/$1 [P,L]
            RewriteCond %{HTTP:Upgrade} !=websocket
            RewriteRule /(.*)           http://localhost:5555/$1 [P,L]

            ProxyPass / http://localhost:5555/
            ProxyPassReverse / http://localhost:5555/
      </VirtualHost>
      <virtualhost *:80>
          ServerName localhost
          DocumentRoot "default path to apache html folder"
      </virtualhost>

**Paste this to /etc/hosts**

        127.0.0.1       app.outgrow.local
        127.0.0.1       live.outgrow.local
        127.0.0.1       livec.outgrow.local
        127.0.0.1       yoursubdomain.outgrow.local

**Restart Apache**

      systemctl status apache2.service

      sudo service apache2 restart

**Or**

      sudo service apache2 reload
