I have a virtual machine base box for Debian wheezy that I've been using with vagrant for the last few months without any issues, however yesterday when I brought up a new machine and updated/upgraded packages I started getting a FastCGI server connection failure error:
[Wed Jun 04 14:39:03 2014] [error] [client 10.0.2.2] (13)Permission denied: FastCGI: failed to connect to server "/vagrant/php5-fcgi": connect() failed
[Wed Jun 04 14:39:03 2014] [error] [client 10.0.2.2] FastCGI: incomplete headers (0 bytes) received from server "/vagrant/php5-fcgi"
I am able to resolve the issue temporarily by manually touching and chmodding /tmp/php5-fpm-vagrant.sock, but my question is why did it start happening all of a sudden?
Personal preferences aside, is there anything functionally wrong with my configuration?:
In my apache sites available I have a file called 000php containing:
FastCgiExternalServer /vagrant/php5-fcgi -socket /tmp/php5-fpm-vagrant.sock -pass-header Authorization
Since apache loads sites alphabetically, this always gets loaded first, then I have another file called vagrant that contains:
<VirtualHost *:80 *:8080>
DocumentRoot /vagrant/public_html/
ServerName vagrant.localhost
<Directory /vagrant/>
AllowOverride all
</Directory>
AddHandler php5-fcgi .php
Action php5-fcgi /php5-fcgi
Alias /php5-fcgi /vagrant/php5-fcgi
ErrorLog ${APACHE_LOG_DIR}/vagrant_error.log
CustomLog ${APACHE_LOG_DIR}/vagrant_access.log combined
</VirtualHost>
and a php fpm pool config called vagrant.conf that looks like this:
[vagrant]
listen = /tmp/php5-fpm-vagrant.sock
listen.allowed_clients = 127.0.0.1
user = vagrant
group = vagrant
pm = ondemand
pm.max_children = 50
any suggestions would be greatly appreciated
Figured out the answer, this was caused by https://bugs.php.net/bug.php?id=67060
The fix was to add the following lines to my vagrant.conf php fpm configuration file and restart php fpm, a reload was not enough
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

I have two apache servers setup on two separate physical machines. My current setup is:
Apache 1 (Reverse Proxy) <===> Apache 2
Both apache server versions are Apache/2.4.29 (Ubuntu) running on Ubuntu 18.04.4 LTS and their /etc/apache2/apache.conf files are identical.
Apache 1 sites-enabled config:
<VirtualHost *:80>
ServerName subdomain.domain.tld
ServerAlias www.subdomain.domain.tld
ServerAdmin webmaster#domain.tld
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyRequests off
ProxyPreserveHost On
ProxyPass /maintenance_page !
ProxyPass / http://[apache2-ip-address]:27300/
ProxyPassReverse / http://[apache2-ip-address]:27300/
</VirtualHost>
Apache 2 sites-enabled config:
<VirtualHost *:27300>
ServerName subdomain.domain.tld
ServerAlias www.subdomain.domain.tld
ServerAdmin webmaster#domain.tld
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
ErrorDocument 400 /notfound.html
ProxyRequests off
ProxyPreserveHost on
</VirtualHost>
If I directly hit http://[apache2-ip-address]:27300/ from the web browser the apache server landing page comes up fine. If I enter http://subdomain.domain.tld into the browser I get a proxy error:
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request
I logged a trace on both apache servers. Apache server 2 is receiving the proxied request from apache server 1 and is returning a 200 status response perfectly fine to apache server 1. The flow breaks at apache server 1 where I am seeing the following logs:

Things I've tried, from few other discussions I could find online, are the following changes to apache server 1 sites-enabled config :
SetEnv proxy-initial-not-pooled 1
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
ProxyTimeout 600
ProxyPass / http://[apache2-ip-address]:27300/ timeout=600
ProxyPass / http://[apache2-ip-address]:27300/ nocanon
I've pretty much bruteforced the situation with several combinations of the above settings, but nothing seems to work. Any help is appreciated.
An additional check I ran is, if I run a nodejs application or python flask service on the same machine as either apache servers and proxy the service using ProxyPass / http://localhost:[port]/, the setup works properly. So both apache servers are running fine and are able to proxy services on their respective localhosts. Whatever is breaking has to do with the communication between the two apache servers.
UPDATE : Upon further triaging using curl with a networking person, the issue seems to be that the org firewall is only allowing inbound traffic to apache server 2 and blocking outbound traffic which may be causing 502 errors on apache server 1. This didn't seem like the issue up until I realized that my laptop was VPN'ed into the org network all along while testing and apache server 1 is sitting outside the org network. If this turns out to be the issue it's going to be a real bummer.
Adding following parameter in the http.conf file solves my issue of "proxy: error reading status line from remote server":
SetEnv proxy-initial-not-pooled 1
I go the reference from Apache URL https://httpd.apache.org/docs/2.4/mod/mod_proxy_http.html
Note: restart http server and try again.
In my case, an error with the database's connection was triggering this Apache's Reverse Proxyng error.
After adding a self-signed SSL certificate, I am unable to get my Drupal site to work on localhost.
I have attempted various proposed solutions that I have found online but none have gotten me past a 400 error at https://localhost/
I have uncommented the following in httpd.conf:
LoadModule ssl_module modules/mod_ssl.so
I have Listen set to port 80 in this same file. When I set it to the SSL channel, 443, Apache does not load.
In my httpd-ssl.conf file:
I have set the paths for my server.crt and server.key files correctly.
I have enabled SSLEngine
<VirtualHost *:443>
# General setup for the virtual host
DocumentRoot "/Applications/MAMP/Library/htdocs"
ServerName https://127.0.0.1:443
ServerAdmin you#example.com
ErrorLog "/Applications/MAMP/Library/logs/error_log"
TransferLog "/Applications/MAMP/Library/logs/access_log"
I have tried a variety of possibilities for the ServerName. The one above along with localhost:443 both lead to 400 errors.
I have Listen set to 443 here. Setting to 80 so it matches the httpd.conf file leads to the same result described above...not able to connect Apache.
Here is my error log for Apache:
Digest: generating secret for digest authentication ...
Digest: done

I don't know enough about Apache server configuration to figure out, when I start MAMP to be able to navigate with HTTPS to my Drupal project, which is in the HTDOCs file and make it run without the 400 error.
I solved the problem by commenting out the line "Document root" above in the virtual host section.
I am trying to make a VirtualHost for my Wordpress project that's being hosted on a EC2 Instance by Apache 2.4 with PHP-FPM. Most of the resources being loaded (mostly scripts and other php) are getting a 404 Error and when I look in the error log for the virtual host, I get the following errors
[Tue Mar 17 01:01:56.026492 2015] [proxy_fcgi:error] [pid 3382] (22)Invalid argument: [client 173.79.19.155:61617] AH01075: Error dispatching request to : (passing brigade to output filters), referer: http://52.21.23.15/project/

Below is my Virtual Host portion of the conf
<VirtualHost *:80>

</Directory>
ErrorLog /var/www/html/project/logs/error.log
</VirtualHost>
And below is the address portion of the php-fpm configuration.
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses on a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000
Please HELP! I have looked everywhere and can not find a solution. I am allowing all traffic to all ports from EC2, I tried all kinds of combinations for different apache Directives, and I even tried to add the js|html and all that stuff to the ProxyPassMatch.
What is causing this?
Help is greatly appreciated.
When i try to connect to my WAMP server using anything but localhost i get error 403.

I tried to start the wamp services as my account (running on win7 x64). I tried to edit these lines in the httpd.config
<Directory />
#Options FollowSymLinks
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order deny,allow
Allow from all
</Directory>
but i still get the error.
EDIT: I installed an older version of WAMP (2.2E) and everything works fine not sure what's different in the newest version (2.4)
Change that section back to
Order Deny,Allow
Deny from all
That section controls access to your root drive and that should always be `Deny from all'
Look for this section of https.conf
# onlineoffline tag - don't remove
And change the section below that to
Allow from 127.0.0.1 ::1 localhost
Also make sure that your hosts file c:\windows\system32\drivers\etc\host has these entries
127.0.0.1 localhost
::1 localhost
EDIT:
You didn't actually say you were using WAMP 2.4. It would have helped:
In that case, read this thread, from the wampserver forum, it describes how to fix a bunch of 2.4 issues.
I'm trying to set up a virtual host for a project that I need to do.
As many tutorials define I activated the virtual host file
Include conf/extra/httpd-vhosts.conf
Placed a virtual host in te file
<VirtualHost *80>
DocumentRoot "C:\Users\Jeroen\Work\Ba\CMS\trunk"
ServerName local.ba-check.be
</VirtualHost>
The hosts file also got a line extr
127.0.0.1 local.ba-check.be
My localhost works, but it returns my document root. Also the error log always gives me this error.
[Thu Jul 07 14:22:55 2011] [error] [client 127.0.0.1] client denied by server configuration: C:/httpd-2.2-x64, referer: http://local.ba-check.be/
I hope somebody could help me.
Thanks
Problems solved
After some time I just reinstalled WAMP and then it worked great.
