I have installed Apache 2.4.6 on Centos7 official.
httpd.conf was not changed from default.
Configured webdav.conf with the following:
DavLockDB /var/www/html/DavLock
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/html/webdav/
ErrorLog /var/log/httpd/error.log
CustomLog /var/log/httpd/access.log combined
Alias /webdav /var/www/html/webdav
<Directory /var/www/html/webdav>
DAV On
</Directory>
</VirtualHost>
webdav directory has 755 rights. DavLock not created.
I keep getting this error and not sure what the cause might be. Have tried many things without success:
[Fri Jan 29 11:41:17.027110 2021] [dav:error] [pid 15068] [client xxx.xxx.xxx.xxx:53946] The locks could not be queried for verification against a possible "If:" header. [500, #0]
[Fri Jan 29 11:41:17.027134 2021] [dav:error] [pid 15068] [client xxx.xxx.xxx.xxx:53946] Could not open the lock database. [500, #400]

any ideas are welcome
Got it working now.
all files/folders under /var/www/ are chown to apache
moved DavLock to here: /var/lib/dav/
and added this line under httpd.conf:
<IfModule mod_dav_fs.c>
# Location of the WebDAV lock database.
DAVLockDB /var/lib/dav/DavLock
</IfModule>
At this point, I am getting 403 error. Solved by executing the following:
chcon -R -t httpd_sys_content_rw_t /var/www/html/webdav/

I am trying to start the apache2 server installed on Ubuntu 22.04 LTS Desktop. However the restart failed and from what I can see in the error log, it is related to my configuration. However I cannot debug further on the exact issue. My apache2 server configuration is as below.

Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xeu apache2.service" for details.
Digging further into systemctl status apache2.service it seems that I have an issue on line 18 in my apache2 configuration file. I have checked that line, and cannot see exactly what the issue is.

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

ProxyPreserveHost On
ProxyPass /maintenance_page !
ProxyPass / http://[apache2-ip-address]:27300/
ProxyPassReverse / http://[apache2-ip-address]:27300/

Apache 2 sites-enabled config:
<VirtualHost *:27300>
ServerName subdomain.domain.tld
ServerAlias www.subdomain.domain.tld
ServerAdmin webmaster#domain.tld

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.
Good Morning StackOverFlow.. I have been troubleshooting this for quite a while.
Problem: When I try to access http://newdash.new it returns a 500 error. This happens both when accessing the URL locally and over the LAN.
Running on Debian8 with Apache 2.4.10
Below is my
/etc/apache2/sites-enabled/newdash.conf
Here:
<VirtualHost *:80>
ServerName newdash.new
ServerAdmin webmaster#localhost
DocumentRoot "/var/www/newdash/public"
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory "/var/www/newdash/public">
Order allow,deny
Allow from all
# New directive needed in Apache 2.4.3:
Require all granted
</Directory>
</VirtualHost>
And the permissions:
drwxr-xr-x 11 root root 4096 Nov 13 10:51 newdash
I can ping the named route (newdash.new) both locally and over the LAN and the ip resolves properly.
In my Apache2 error log:
[Fri Nov 13 11:45:51.345101 2015] [:error] [pid 1958] [client 10.1.1.108:56899] PHP Fatal error: Uncaught exception 'UnexpectedValueException' with message 'The stream or file "/var/www/newdash/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied' in /var/www/newdash/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:87\nStack trace:\n#0 /var/www/newdash/vendor/monolog/monolog/src/Monolog/Handler/AbstractProcessingHandler.php(37): Monolog\\Handler\\StreamHandler->write(Array)\n#1 /var/www/newdash/vendor/monolog/monolog/src/Monolog/Logger.php(289):
So it appears there is a permissions error on that directory..
I don't know what other information would be helpful...
Thank you.
I found the error in the error log.

As suggested, after looking there, I realized the permissions on the /storage/logs/ folder was causing the issues.
Thank you for the suggestion arkascha!
I've set up Pow and Apache the way they suggest in this tutorial. My httpd-vhosts.conf contains the following entry.
<VirtualHost *:80>
DocumentRoot /Users/michael/Dropbox/Development/test
ServerName test.dev
<Directory "/Users/michael/Dropbox/Development/test">
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
I'm still getting a 403 Forbidden when I got to http://test.dev/.
Error log says:
[Wed Nov 21 19:24:21 2012] [crit] [client 127.0.0.1] (13)Permission denied: /Users/michael/Dropbox/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable
[Wed Nov 21 19:24:43 2012] [error] [client 127.0.0.1] (13)Permission denied: access to / denied
Has anyone else had this problem?
This seems to have nothing to do with Pow. Apache doesn't have the necessary permissions to work within /Users/michael/Dropbox/Development/test.
Please check the permissions of this directory, I think they should be 755. Check them with:
cd /Users/michael/Dropbox/Development/
ls -l
And copy paste the line of the test directory.
The issue was the permissions. It finally worked when I chmod'd the full path to the directory I was working in to 755.
~/, ~/Dropbox, ~/Development...etc.
I'll bet there's a nicer way to do this, but it's working. So, there you go.

I've been trying to set up trac to be deployed with apache for a little while now and I'm running into a wall.
I can get it to work via tracd but I'm probably going to have multiple projects and I might want to use TSL for connections to trac.
This is the response I'm receiving from my server

Does anyone know what might be going on and what I should do to fix it? Thanks!
Is this on Windows? As noted in this question, running Python with FastCGI on Windows is bound to fail.
I recommend switching to mod_wsgi which is the recommended approach anyway.
