getting error on installing mpm-worker in ubuntu apache2.
How to fix this problem?
There is no apache2-mpm-worker package because the mpm_worker module is included by default when you install Apache on Ubuntu's newer versions. It is contained in the apache2-bin package that is a dependency of apache2:
sudo a2dismod prefork event php* && sudo a2enmod worker
If you see any errors like cannot enable module (similar), then let me know with the whole output. Make sure you enable php-fpm when you use prefork, if you wish to use PHP.

I am a new to web development.I have created Django(-v 2.2) web application and I want to deploy it on my linux server(OS Centos).After installation apache2, when I was going to install libapache2-mod-wsgi-py3, it says that no package available. Is there different name for libapache2-mod-wsgi-py3 for OS Centos?
It is always recommended to install mod_wsgi directly into the python3 package using pip3.
pip3 install mod_wsgi
If you install mod_wsgi into the OS, it could cause conflict and unexpected behavior.
Do you have apache2-dev installed?
Also, for mod_wsgi it is better to go the CMMI path (configure-make-make install) in order to compile it with the correct version and load it in Apache as a module. This worked for me on Debian VPS:
To do so,
wget https://github.com/GrahamDumpleton/mod_wsgi/archive/4.6.5.tar.gz
tar xvfz 4.6.5.tar.gz
cd mod_wsgi-4.6.5
whereis apxs
whereis python3
./configure --with-apxs=/usr/bin/apxs --with-python=/usr/bin/python3.5
make
sudo make install
Double check the path for apxs and python, and run make install as sudo.
When it’s all ready, check the last line of prompt results, as there will be a path to a file: /usr/lib/apache2/modules/mod_wsgi.so
To cleanup after installation, run:
make clean
If you need to build the module for a different version of Apache, you should run:
make distclean
If you have a httpd.conf file, you should edit and add this line:
LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so
If not, create it and paste that line, and edit /etc/apache2/apache2.conf. file, by adding this line:
Include /etc/apache2/httpd.conf
You don't need that file to configure apache, but you can create it if other software relies on it being there.
You should restart Apache and check the log
sudo tail /var/log/apache2/error.log
as there should be a line that says:
Apache/2.4.25 (Debian) mod_wsgi/4.6.5 Python/3.5 configured -- resuming normal operations
When I recently installed PHP56 via Homebrew, Apache would no longer start, with this error in the logs:
Cannot load /usr/local/opt/php56/libexec/apache2/libphp5.so into server: dlopen(/usr/local/opt/php56/libexec/apache2/libphp5.so, 10): image not found
Note: I'm running Apache 2.4 on Mac El-Capitan.
How can I resolve this error and get Apache running again?
I've seen this before. If you brew options php56, it says:
With the release of macOS Sierra the Apache module is now not built by default. If you want to build it on your system
you have to install php with the --with-apache option. See brew options php56 for more details.
Thus, try uninstalling (brew uninstall php56) then reinstalling php56 with the flag --with-apache for Apache v2.4.x (--with-apache22 for Apache 2.2). Generally, you can check your Apache version by typing in command line: httpd -v.
My version is 2.4.18, so I would brew install php56 --with-apache, which creates the proper file path /usr/local/opt/php56/libexec/apache2/libphp5.so.
Now, it is properly compiled with Apache Handler module.
IMPORTANT: installing php56 with this option appears to also install httpd24. From a brew program stance, this makes sense. However, this may break your server set up. If you don't want to use brew's Apache install, do a brew unlink httpd24 after this.
To see additional brew build options, try brew options php56.
I am trying to install Cobbler on a brand new Ubuntu 15.10 virtual box but it is not working. When I run the apt-get install cobbler cobbler-web it seems to break apache completely to the point I can't get it working again.
I see this in the apache error log:
[wsgi:crit] [pid 8112:tid 140273573488512] mod_wsgi (pid=8112): The mod_python module can not be used on conjunction with mod_wsgi 4.0+. Remove the mod_python module from the Apache configuration.
and this in the auth.log:
polkitd(authority=local): Unregistered Authentication Agent for unix-process:8081:54865 (system bus name :1.24, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus)
I have tried removing the mod_python and wsgi modules but apache still doesn't start up. And I think Cobbler uses them anyways, so I kind of need them.
I have also tried disabling polkitd. I don't find any clues when searching for that weird error message.
I was able to install Cobbler on Ubuntu 14.04 pretty easily and apache works fine.
Here is the basic chain of install commands I used:
apt-get update
apt-get install apache2
apt-get install isc-dhcp-server
apt-get install bind9 bind9utils bind9-doc
apt-get install cobbler cobbler-web debmirror mkisofs
Disable the module by typing sudo a2dismod python
You should then see this:
Module python disabled. To activate the new configuration, you need to
run: service apache2 restart
So type sudo service apache2 restart.
If that doesn't fix it, check the error log for more information by typing
cat /var/log/apache2/error.log.
hello i trying to install libapache2-mod-fcgid mod but have always get error.

Some packages could not be installed. This may mean that you have

distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies:
libapache2-mod-fcgid : Depends: apache2.2-common but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
and without fcgid mod i cannot launch apache server

Output of config test was:

This worked for me: Ubuntu 21.10 in year 2022:
sudo apt-get install -y libapache2-mod-fcgid
I know it is a bit late for a response but, since there is no answer yet, I'll put one.
In this situation, the dependencies from libapache2-mod-fcgid are not met. In this case, you could download and install apache2.2-common prior the installation of libapache2-mod-fcgid like this:
sudo apt-get install apache2.2-common
and then try your install command afterward.
I got the below error while I was configuring CKAN DataPusher.
Invalid command 'WSGIScriptAlias', perhaps misspelled or defined by a
module not included in the server configurationAction 'configtest'
failed.
How can I fix this?
Try to enable wsgi mod in Apache
sudo a2enmod wsgi
If you come across below error
ERROR: Module mod-wsgi does not exist!
You will have to install mod wsgi as below. What you have to do is run the following commands,
sudo apt-get install libapache2-mod-wsgi
sudo a2enmod wsgi
sudo service apache2 restart
To enable wsgi_mod in httpd, install the module
sudo yum install mod_wsgi
and make sure to load the module in the httpd config file
sudo nano /etc/httpd/conf/httpd.conf
then add the following line in the config file, to the list of other loaded module:
LoadModule wsgi_module modules/mod_wsgi.so
I had this error after messing up my Apache installation and restarting the setup after an apt purge apache2. This also seems to have removed the wsgi mod but Ubuntu 20 LTS kept thinking it's still around.
So I had to to purge and reinstall the wsgi mod from scratch:
apt purge -y libapache2-mod-wsgi-py3
apt install -y libapache2-mod-wsgi-py3
a2enmod wsgi
After that, Apache was able to find it again.
I faced this problem because
I installed mod_wsgi which was compatible with python3.5, but my project's virtual environment was using python3.7. So, mod_wsgi for 3.7 was required. I installed that as well (python3.7 -m pip install mod_wsgi). But a configuration was missing from apache2 which resulted in this issue.
run : mod_wsgi-express module-config
add the output in /etc/apache2/apache.conf
( LoadModule wsgi_module "/home/user/.local/lib/python3.7/site-packages/mod_wsgi/server/mod_wsgi-py37.cpython-37m-x86_64-linux-gnu.so"
WSGIPythonHome "/usr" )
then restart - sudo service apache2 restart
This solved the problem.
I think you might need to add this line in your apache2.conf
LoadModule wsgi_module "/usr/local/lib/python3.6/dist-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"
Below command will give you the above output
mod_wsgi-express module-config
