Where did my apache module get installed - apache

I'm trying to get Crowd Apache Connector working. I've installed the modules. If I do a yum info it tells me that it's installed. If I do httpd -M it's listed as a shared module. However, it's not in apache/modules/
When I try the LoadModule in the pre main include, I get the error that it cannot load it into the server because it doesn't exist.
The error after trying to load the module:
Configuration problem detected on line 1 of file /usr/local/apache/conf/includes/pre_main_global.conf.tmp: : Cannot load /usr/local/apache/modules/mod_authnz_crowd.so into server: /usr/local/apache/modules/mod_authnz_crowd.so: cannot open shared object file: No such file or directory --- /usr/local/apache/conf/includes/pre_main_global.conf.tmp --- 1 ===> LoadModule authnz_crowd_module modules/mod_authnz_crowd.so <=== 2LoadModule authz_svn_crowd_module modules/mod_authz_svn_crowd.so --- /usr/local/apache/conf/includes/pre_main_global.conf.tmp ---

I figured it out. After reinstalling it, I checked the httpd.conf file and found that it was installing it to:
/usr/lib64/httpd/modules/mod_authnz_crowd.so
Knowing that I was able to get it working.

Flask Apache Start Fails with Permission Denied

I am trying to install Flask on my CentOS 7.9.2009 VM running Apache HTTP Server. I've installed Python3.8 and mod_wsgi but when I attempt to start Apache I get the below Permissioned denied when loading the mod_wsgi. I've checked multiple blogs and forums and cannot find a resolution. Any idea why I am getting this error?
Error: cannot open shared object file: Permission denied
httpd: Syntax error on line 56 of /etc/httpd/conf/httpd.conf: Syntax error on line 1 of /etc/httpd/conf.modules.d/02-wsgi.conf: Cannot load /home/myuser/.local/lib/python3.8/site-packages/mod_wsgi/server/mod_wsgi-py38.cpython-38-x86_64-linux-gnu.so into server: /home/myuser/.local/lib/python3.8/site-packages/mod_wsgi/server/mod_wsgi-py38.cpython-38-x86_64-linux-gnu.so: cannot open shared object file: Permission denied
I installed python3.8 from source using ./configure --enable-optimizations --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" but I am still getting the above permission denied error.
Below is how my app.conf file looks like and also output of mod_wsgi module-config.
app.conf:
LoadModule wsgi_module "/home/myuser/.local/lib/python3.8/site-packages/mod_wsgi/server/mod_wsgi-py38.cpython-38-x86_64-linux-gnu.so"
mod_wsgi module-config:
[myuser#mycentos conf.d]$ mod_wsgi-express module-config
LoadModule wsgi_module "/home/myuser/.local/lib/python3.8/site-packages/mod_wsgi/server/mod_wsgi-py38.cpython-38-x86_64-linux-gnu.so"
WSGIPythonHome "/usr/local"
I get the error when I try to start Apache - sudo systemctl start httpd.
The permission issue was because of SELinux enabled/enforced on my system. I reached out to one of the mod_wsgi source code authors and he pointed me to check this. For now disabling this resolved my immediate issue. If others have suggestions to resolve this without turning it off please suggest.

How can I solve this problem of installation xampp on fedora?

When I run xampp on fedora this error is showing up on application log
Starting Apache Web Server...
Exit code: 8
Stdout:
apache config test fails, aborting
Stderr:
httpd: Syntax error on line 522 of /opt/lampp/etc/httpd.conf: Syntax error on line 10 of /opt/lampp/etc/extra/httpd-xampp.conf: Cannot load modules/libphp7.so into server: libnsl.so.1: cannot open shared object file: No such file or directory
can anyone tell me how can I solve this?
it seems you're missing libnsl. install it through this command:
sudo dnf install libnsl
In case this doesn't work you can then download it manually:
Visit https://pkgs.org/
In the search box (pkgs.org of course) type libnsl.so.1 and choose the appropriate OS. The version shown might be higher e.g libnsl-2.28-9.fc29.x86_64.rpm, but it doesn't matter, the file needed is also included in this very package.
In the terminal, navigate to the directory where the .rpm was downloaded.
Type the following command to install it:
sudo rpm libnsl-2.XX-X.fc29.x86_64.rpm
Upon completion everything should be working fine.
A quick Google search returns this: https://www.reddit.com/r/Fedora/comments/8hlhlv/xampp_with_fedora_28/
The suggested fix is installing libnsl from this source:

Apache mod_ssl could not be loaded

Trying to enable the mod_ssl module on Apache 2.4.25, I get the following error:
httpd: Syntax error on line 129 of /ld01/otsweb/build/apache/httpd24.conf: Cannot load modules/mod_ssl.so into server: \t0509-022 Cannot load module /usr/local/apache24/modules/mod_ssl.so.\n\t0509-150 Dependent module libssl.so could not be loaded.\n\t0509-022 Cannot load module libssl.so.\n\t0509-026 System error: A file or directory in the path name does not exist.\n\t0509-022 Cannot load module /usr/local/apache24/modules/mod_ssl.so.\n\t0509-150 Dependent module /usr/local/apache24/modules/mod_ssl.so could not be loaded.
Line 129 is the LoadModule ssl_module modules/mod_ssl.so line in the httpd.conf file.
I have the same configuration running correctly on another server. That server does not have a libssl.so file on it, yet Apache with SSL is running.
Apache was configured with: (OpenSSL version is 1.0.2k from openssl.org)
./configure --enable-mods-shared="proxy proxy_http" --enable-auth-digest --enable-ssl --with-ssl=/usr/local/ssl/bin
Has anyone seen this same error?
With the release of OpenSSL 1.0.2l we decided to reinstall Apache from scratch, and everything is working correctly. A clean install of both seems to have cleared out the problem.

Mod_wsgi - configuration failed

I am trying to install mod_wsgi using with apache2 but i cant:
I placed the mod_wsgi.so file in C:\Apache24\modules directory
In httpd conf file
1) when i try to LoadModule wsgi_module modules/mod_wsgi.so and restart apache then apache cannot be started - I get an error "The requested operation has failed"
2) when i remove the previous line and add "WSGIScriptAlias /myapp C:/wsgi-scripts/myapp.wsgi" i get the same error
reinstalled python for all users and this resolved itself, I must have installed python on windows for "just me" before

Error installing libapache2-mod-rpaf for detecting IPs using nginx as a reverse proxy

I've seen here, that I should install mod_rpaf so that Apache will be able to detect the IPs coming from the Nginx reverse proxy.
Even seen that there is a bug on Ununtu SO, and it should be solved changing the first line on /etc/apache2/mods-available/rpaf.conf.
The first line contains <IfModule rpaf_module>. I've tried replacing with <IfModule mod_rpaf-2.0.c>, but nothing changes when I restart the Apache.
This is the output when I try to install this module:
apt-get install libapache2-mod-rpaf

Per the error, you already have a version of /usr/lib/apache2/modules/mod_rpaf.so on your system with a filehash that differs from what the package config is expecting (expected signature 41503234 but saw 41503232), so you either need to:
1) Work out what installed the conflicting version and uninstall it:
dpkg -S /usr/lib/apache2/modules/mod_rpaf.so
apt-get --purge remove <package>
Or if manually added:
mv /usr/lib/apache2/modules/mod_rpaf.so /usr/lib/apache2/modules/mod_rpaf.so.bak
apt-get install libapache2-mod-rpaf
This may break other stuff.
2) Manually download, re-compile and install from source, should solve the immediate issue, but you'll hit the same conflicting signature issue if you try to update via apt.
3) Unpack the deb file, hack the hash in the config, repackage and install.
