6. Add maintenance options(deploy:web:enable, deploy:web:disable) in /home/<appuser>/tincan
7. Open the runcap.sh file from the follwing location and do the below changes
cd /home/<appuser>/tincan vi runcap.sh
8. In the printmenu() function add two more cases (ie) case 3 and case 4 to make the selection (Enable / Disable) for maintenance page
Add the following statements below this statement " echo "2). deploy:restart" "
echo "3). deploy:web:enable (Use this to remove maintenance page, all app servers are enabled)"
echo "4). deploy:web:disable (Use this to install maintenance page, public access to all app servers is disabled)"
Do the below change in the next line
Initially it will be like this " read -p 'Enter Cap Task number [1-2]: ' captask ". It has to be changed like this "read -p 'Enter Cap Task number [1-4]: ' captask "
9. Add two below mentioned fuction to perform the site maintenance page operation
addMaintenenceMode()
{
echo `pwd`
cd /deploy/tincan/current
echo `pwd`
bundle exec rake maintenance:start allowed_ips="182.72.26.6"
}
In the addMaintenenceMode() function we are allowing the ipaddress “182.72.26.6” to access the site even though the site in maintenance mode because it is our public ip
removeMaintenenceMode()
{
echo `pwd`
cd /deploy/tincan/current
echo `pwd`
bundle exec rake maintenance:end
}
Save the file and exit
