Customized 502 Bad Gateway Page(Nginx)

During the task like database migration, php5-fpm service can be stopped,so that nobody can access the Wordpress site during database maintenance is underway.

Stop the php5-fpm service

sudo service php5-fpm stop

After this accessing the website will show 502 Bad Gateway. We will replace this error with "Under Manintainance Page"

Configuring and creating custom 502(Bad Gateway)

sudo nano /etc/nginx/sites-enabled/default

Add the following config code in port 443 section of Nginx config file which is stated above.

        error_page 502 /custom502.html;
        location = /custom502.html {
                root /var/www/html;
Enter fullscreen mode Exit fullscreen mode

After that create /var/www/html/custom502.html

                Site is currently under maintenance. Thank you for your understanding.
Enter fullscreen mode Exit fullscreen mode

Restart the nginx server

sudo service restart nginx

After this access the website to see the "Under Maintenance Page" instead of Bad Gateway
