Application error Rails application failed to start properly issue

Added by Oscar Morao about 1 year ago

Hi all,

I've already installed redmine and ran with webrick.

When deployed trying to use mod_fcgi (Shared) I'm always getting this Apache error.

[Mon Nov 29 16:37:23.314074 2021] [core:error] [pid 29933:tid 46975154824960] [client] End of script output before headers: dispatch.fcgi

In google chrome I got this message.

Application error
Rails application failed to start properly

For this config, I've added a gem 'fcgi' to handle the setup, but seems there's something wrong.

This is my .htaccess
  1. General Apache options
    <IfModule mod_fastcgi.c>
    AddHandler fastcgi-script .fcgi
    <IfModule mod_fcgid.c>
    AddHandler fcgid-script .fcgi
    Options +FollowSymLinks +ExecCGI
  1. If you don't want Rails to look in certain directories,
  2. use the following rewrite rules so that Apache won't rewrite certain requests #
  3. Example:
  4. RewriteCond %{REQUEST_URI} ^/notrails.*
  5. RewriteRule .* - [L]
  1. Redirect all requests not available on the filesystem to Rails
  2. By default the cgi dispatcher is used which is very slow #
  3. For better performance replace the dispatcher with the fastcgi one #
  4. Example:
  5. RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
    RewriteEngine On
  1. If your Rails application is accessed via an Alias directive,
  2. then you MUST also set the RewriteBase in this htaccess file. #
  3. Example:
  4. Alias /myrailsapp /path/to/myrailsapp/public
    #RewriteBase /redmine

RewriteRule $ index.html [QSA]
RewriteRule ^([
.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
<IfModule mod_fastcgi.c>
RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
<IfModule mod_fcgid.c>
RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]

  1. In case Rails experiences terminal errors
  2. Instead of displaying this message you can supply a file here which will be rendered instead #
  3. Example:
  4. ErrorDocument 500 /500.html

ErrorDocument 500 "<h2>Application error</h2>Rails application failed to start properly"


My dispatch file. I've checked my folders and I have a /usr/bin/ruby file.

require File.dirname(FILE) + '/../config/boot'
require File.dirname(FILE) + '/../config/environment'

class Rack::PathInfoRewriter
def initialize(app)
@app = app

def call(env)
parts = env['REQUEST_URI'].split('?')
env['PATH_INFO'] = parts[0]
env['QUERY_STRING'] = parts[1].to_s

I don't know what else can I try. I've changed a lot of parameters in the dispatcher and didn't find a solution on internet.

Any help please?
