On macOS Sierra, I installed Apache using Homebrew:
$ brew install httpd24
This has caused some weird Apache issues. It seems that the default installation of Apache on macOS Sierra was still active in some way. I now want to completely uninstall httpd24 but am still seeing it in my processes. Here's what I did:
$ brew unlink httpd24
$ brew uninstall httpd24
$ rm -rf /usr/local/etc/apache2/
Running $ ps aux|grep httpd reveals:

The processes with the path /usr/sbin/httpd are the default Apache installation. The ones with the path /usr/local/Cellar/httpd24/2.4.23_2/bin/httpd is the Homebrew installation. This shouldn't even be possible. The directory /usr/local/Cellar/httpd24 doesn't even exist. I have tried manually killing those processes but they eventually come back. I have tried restarting my computer. I have restarted Apache countless times. I have confirmed that the Apache I am interacting with on the command line using $ apachectl is the default installation. I don't know what else to do. Thank you for any help.
I can't remember what exactly I did to resolve this, but I've pieced together a bash alias that might be useful to other people who are using Homebrew PHP but the default Mac OS Apache. It will stop Apache, kill any Homebrew Apache (httpd24) processes, unlink and uninstall Homebrew Apache and restart the remaining default Apache installation. Occasionally I have to use this after installing a new PHP version using Homebrew. See this issue for more information: https://github.com/Homebrew/homebrew-php/issues/3601
alias fix_apache='sudo apachectl stop; sudo pkill -f /usr/local/Cellar/httpd24; sudo pkill -f /usr/sbin/httpd; sudo pkill -f /usr/local/opt/httpd24; brew unlink httpd24; brew uninstall --ignore-dependencies --force httpd24; sudo apachectl start;'
I had the same problem and have followed #maskedjellybean answer, by upgrading the script for httpd, according to #pilot comment (i am using currently version 2.4.48).
Code follows:
alias fix_apache='sudo apachectl stop; sudo pkill -f /usr/local/Cellar/httpd; sudo pkill -f /usr/sbin/httpd; sudo pkill -f /usr/local/opt/httpd; brew unlink httpd; brew uninstall --ignore-dependencies --force httpd; sudo apachectl start;'
It all worked perfectly.

I have an Ubunto 18.04 LTS running with apache2 and various PHP versions (5.6 up to 8.0).
Apache is configured to run as the same user as my FTP user (let's call him 'test').
ps aux | grep apache2
says this user name for the processes.
Problem: When I run my website on it, which creates a file, then the file is created as user 'www-data', which only works if I give 777 permission to the folder, as the folder has the user 'test' as it's owner.
Question: How can I make apache write files as the user used for the process it runs with?

I'm trying to initialize Yii2 apps and after i run the command php init and all files generated by yii i try to view from n=my browser but keep getting error, i have search on google and on stackflow for possible solution with no luck, what i've tried so far, i run the command chmod 0777 web/assets i also do ps -ef | grep apache | grep -v grep and i got the below
apache 4074 4073 0 20:38 ? 00:00:01 /usr/sbin/httpd -DFOREGROUND
apache 4075 4073 0 20:38 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND

apache 4083 4073 0 20:38 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND
the i proceed doing sudo chgrp apache ./assets and then sudo chmod g+w ./assets/ it all not working i guess this is a kind of server problem, any help on this will be appreciated thanks
maybe the directory owner has conflict with your php user,
run this command to get your apache user:
ps -ef | grep apache | grep -v grep
then you can see {apache_user}, run below command in your frontend/web directory:
sudo chgrp {apache_user} ./assets
sudo chmod g+w ./assets/
but if it doesn't work, give me about your operation system information
I have install apache httpd 2.4.34 on SLES 15, and there are six httpd processes running.
When I send signal SIGTERM to httpd process, all the six httpd process couldn't receive signal SIGTERM (I had gdb attched httpd process to catch signal SIGTERM),
but I find kill 15 11143 return 0 via command strace. But httpd could reiveive signal SIGKILL, it's very strange.
And apache httpd 2.4.34 running on other platform(SLES12, SLES11, RHEL7) could reiveive and handle signal SIGTERM normally.
Does anyone encounter this phenomenon?

What is this about ?
Every line with /usr/sbin/apache2 -k start represents the command that started an apache process with the argument -k start to run a new instant of apache
Apache2 comes by default with many distributions, you can remove it if you only want ngix
Does anyone know why this command,
ssh -v user#address "exec ssh-agent bash"
...would hang on this output?
debug1: Sending command: exec ssh-agent bash
I'm trying to automatically setup a set of remote machines so they can SSH into each other without passwords. Have already scp'd over the relevant private key file. Need to run ssh-add on each instance. But first, I need to start the ssh-agent. But the command above hangs. Starting the agent manually on each instance is not really an option.
Running "ps ux" on the remote machine manually confirms that the ssh-agent is running:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
ubuntu 746 0.0 0.2 8844 1380 ? S 02:45 0:00 sshd: ubuntu#notty

ubuntu 813 0.0 0.1 4284 1076 pts/0 R+ 02:52 0:00 ps ux
Any help is appreciated.
What you see is the expected behavior. SSH is waiting for bash to finish execution. If you omit the "bash" as the argument to ssh-agent, then ssh-agent goes in the background like you expect it to.
So, perhaps you meant to run:
ssh -v user#address "ssh-agent"
looking at pstree output shows more clearly what is happening.
