6 How To Configure Apache to Use Custom Error Pages on Ubuntu 14.04 Posted Jun 9, 2015 45.6k views Apache Ubuntu Introduction Apache is the most popular web server in the world.
Apache 500 Error
It is well-supported, feature-rich, and flexible. When designing your web pages, it is often helpful to customize every piece of content that your users will see. This includes error pages for when they request content that is not available. In this guide, we'll demonstrate how to configure Apache to use custom error pages on Ubuntu 14.04. Prerequisites To get started on with this guide, tomcat 503 error you will need a non-root user with sudo privileges. You can set up a user of this type by following along with our initial set up guide for Ubuntu 14.04. You will also need to have Apache installed on your system. Learn how to set this up by following the first step of this guide. Creating Your Custom Error Pages We will create a few custom error pages for demonstration purposes, but your custom pages will obviously be different. We will put our custom error pages in the /var/www/html directory where Ubuntu's Apache installation sets its default document root. We'll make a page for 404 errors called custom_404.html and one for general 500-level errors called custom_50x.html. You can use the following lines if you are just testing. Otherwise, put your own content in these locations:
- echo "
Error 404: Not found :-(
" | sudo tee /var/www/html/custom_404.html - echo "
I have no idea where that file is, sorry. Are you sure you typed in the correct URL?
" | sudo tee -a /var/www/html/custom_404.html - echo "
Oops! Something went wrong...
" | sudo tee /var/www/html/custom_50x.html generic error responses in the event of 4xx or 5xx HTTP status codes, these responses are rather stark, uninformative, and can be intimidating to site users. You may wish

to provide custom error responses which are either friendlier, or in some language other php custom error page than English, or perhaps which are styled more in line with your site layout. Customized error responses can be defined for apache custom error pages any HTTP status code designated as an error condition - that is, any 4xx or 5xx status. Additionally, a set of values are provided, so that the error document can be customized further based on the https://www.digitalocean.com/community/tutorials/how-to-configure-apache-to-use-custom-error-pages-on-ubuntu-14-04 values of these variables, using Server Side Includes. Or, you can have error conditions handled by a cgi program, or other dynamic handler (PHP, mod_perl, etc) which makes use of these variables. Configuration Available Variables Customizing Error Responses Multi Language Custom Error Documents See alsoComments Configuration Custom error documents are configured using the ErrorDocument directive, which may be used in global, virtualhost, or directory context. It may be used in .htaccess https://httpd.apache.org/docs/2.4/custom-error.html files if AllowOverride is set to FileInfo. ErrorDocument 500 "Sorry, our script crashed. Oh dear" ErrorDocument 500 /cgi-bin/crash-recover ErrorDocument 500 http://error.example.com/server_error.html ErrorDocument 404 /errors/not_found.html ErrorDocument 401 /subscription/how_to_subscribe.html The syntax of the ErrorDocument directive is: ErrorDocument <3-digit-code>
where the action will be treated as: A local URL to redirect to (if the action begins with a "/"). An external URL to redirect to (if the action is a valid URL). Text to be displayed (if none of the above). The text must be wrapped in quotes (") if it consists of more than one word. When redirecting to a local URL, additional environment variables are set so that the response can be further customized. They are not sent to external URLs. Available Variables Redirecting to another URL can be useful, but only if some information can be passed which can then be used to explain or log the error condition more clearly. To achieve this, when the error redirect is sent, additional environment variables will be set, which will be generated from the headers provided to the original request by prepending 'REDIRECT_' onto the original header name. This provides the error document the context of the original request. For example, you might receive, in addition to more usual environment variables, the 8.

Author: Deron Eriksson error page Description: This tutorial describes how to have Apache display a custom error page when an application deployed to Tomcat is down. Tutorial created using: Windows XP || Apache HTTP Server 2.2.21 Page: 1 In another tutorial, we saw how we could connect an ApacheSW Web Server to a TomcatSW servletW container using a proxy. custom 503 error As an example, in my http.conf Apache configuration file, here's a proxy so that requests to URL paths starting with /tutorials will be handled by the tutorials JavaSW web application running on Tomcat. Tomcat is using its standard port, 8080.
ProxyPass /tutorials http://localhost:8080/tutorials ProxyPassReverse /tutorials http://localhost:8080/tutorials If Tomcat isn't running or if the "tutorials" application isn't available, Apache will display a default 503 Service Temporarily Unavailable error message. A common requirement is to have Apache display a custom maintenance error page when Tomcat is down or when an application running in Tomcat is down. This is quite easy to do. All we need to do is add an ErrorDocument entry to our http.conf file. On the ErrorDocument line, we specify the error code, which in this case is a 503. After that, we can specify either a text message or the page to display. I'll specify to display the "maintenance-message.html" page, which I create in the Apache document rootStart here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Server Fault Questions Tags Users Badges Unanswered Ask Question _ Server Fault is a question and answer site for system and network administrators.

The configuration on the Virtual Host in Apache is:
ProxyPass /Site1/ServLet1 http://1.1.1.1/Site1/ServLet1 ProxyPassReverse /Site1/ServLet1 http://1.1.1.1//Site1/ServLet1 ProxyPass /Site2/ServLet2 http://2.2.2.2/Site2/ServLet2 ProxyPassReverse /Site2/ServLet2 http://2.2.2.2/Site1/ServLet1 Essentially, if it comes to 10.10.10.10 and requests /Site1/ServLet1, route it to /Site1/ServLet1. if I addProxyPass /Site1/ServLet1 http://1.1.1.1/Site1/ServLet1 ProxyPassReverse /Site1/ServLet1 http://1.1.1.1//Site1/ServLet1 ErrorDocument 404 /customerrors/site1/404.html ProxyPass /Site2/ServLet2 http://2.2.2.2/Site2/ServLet2 ProxyPassReverse /Site2/ServLet2 http://2.2.2.2/Site1/ServLet1 so it will show a custom error for site1 (I set the ErrorDocument), it will be served to both. How can I have a different 404 error page per site maintaining this kind of configuration? Thank Edit: if I modify the configuration based on the comments below like:ProxyPass http://1.1.1.1/Site1/ServLet1 ProxyPassReverse http://1.1.1.1/Site1/ServLet1 ErrorDocument 404 /customerrors/site1/404.html Then I can still get to http://1.1.1.1/Site1/ServLet1 but no error page is displayed whatsoever apache-2
