====== Apache - Create a maintenance page ====== Sometimes you need to place a site into maintenance mode for some reason. This is the easy way to do it. 1. Create a directory named err/ in the root directory. Lets say the site is called example.com.


cd /var/www/html/example.com
mkdir err

2. Create a file named 503.html in the err directory.


cd /var/www/html/example.com/err
touch 503.html

3. Put a maintenance message into 503.html.


echo "This site is currently under maintenance. Thank you" > 503.html

4. Add below lines to your virtual host setting for example.com.


ErrorDocument 503 /err/503.html
## uncomment below to enter maintenance mode
RedirectMatch 503 ^/(?!err/)

5. Restart Apache.


httpd -k graceful

6. Test the website.
