After purging and reinstalling Apache2 through apt-get install apache2, it does not start. After starting service apache2 start, it does not give any message. systemctl status apache2 gives the following:
● apache2.service - LSB: Apache2 web server
Loaded: loaded (/etc/init.d/apache2)

there is nothing hanging on port 80. simple http-servers (by Python eg) work ok.
there is nothing in log - all files are empty.
How to make apache work?
I've found the answer. thanx for your attention. For that here is what i did for solving this.
What I have done
I've found that I do not have /usr/sbin/apache2 AT ALL. Have no idea, how it's happend. sudo apachectl configtest told me about it.
Took /usr/sbin/apache2 from backup. surely I could reinstall it from apt-get.
After that, doing sudo apachectl configtest, I've found a message like that:
apache2: Syntax error on line 140 of /etc/apache2/apache2.conf:
Syntax error on line 2 of /etc/apache2/mods-enabled/access_compat.load:
Cannot load /usr/lib/apache2/modules/mod_access_compat.so into server:
/usr/lib/apache2/modules/mod_access_compat.so: cannot open shared object file: No such file or directory
Action 'configtest' failed.
it was cured by sudo apt-get --reinstall install apache2-bin
that's all. thank you
Solved:
$ sudo apt-get update
$ sudo apt-get install apache2

My operating system is Red Hat Enterprise Linux 7. This isn't working...
# httpd -t
bash: httpd: command not found
In case it helps, this is the command I run to restart apache on this box...
# systemctl restart httpd24-httpd
But this doesn't work...
# httpd24-httpd -t
bash: httpd24-httpd: command not found
This doesn't work either...
# apachectl -t
bash: apachetl: command not found
Nor does this work...
# apachectl configtest
bash: apachetl: command not found
I know this is a couple months old but ended up here. I ran into the same issue initially, hence why I am here. I found that the location for the new httpd24-httpd wasn't in my env path to execute. While I could added it there, I found the command location and was able to execute.
How I found the command:
sudo find / -name apachectl
The output of the command:
/opt/rh/httpd24/root/usr/sbin/apachectl
Executed the command:
sudo /opt/rh/httpd24/root/usr/sbin/apachectl
Turns out I have to fix my configuration.
httpd: Syntax error on line 56 of /opt/rh/httpd24/root/etc/httpd/conf/httpd.conf: Syntax error on line 40 of /opt/rh/httpd24/root/etc/httpd/conf.modules.d/00-base.conf: Cannot load modules/mod_http2.so into server: libnghttp2-httpd24.so.14: cannot open shared object file: No such file or directory
Interesting that this came up for me, as I've not done anything with the configuration in this regard.
Here's the version I am running.
sudo /opt/rh/httpd24/root/usr/sbin/apachectl -v
Server version: Apache/2.4.34 (Red Hat)
Server built: Mar 17 2020 09:34:59
All the best!
Found something more for this as well from an old bug submitted to Redhat

I am trying to install Devstack but it stopping in the middle
Currently trying to install openstack, but the long process of individual installation, so am using devstack, however i already install OSM release 5. I just need a vim to put the images.

Upon running apache restart, its gives this.

So i tried to kill all pids then it's ok for once, after that it comes back up

Except i kill the pids again. I don't understand why this is happening.
I expect the devstack to install completely. It's just tiring
Try to reinstall apache2.
It worked for me.
sudo apt-get reinstall apache2
Last time I try add new domain on localhost and I leave it on few weeks so now I try run my apache this command /etc/init.d/apache2 start and I get error
[....] Starting apache2 (via systemctl): apache2.serviceJob for apache2.service failed. See "systemctl status apache2.service" and "journalctl -xe" for details.
failed!
If i tried to do reinstall apache2 but it is still not work.
I just did these two lines.It worked.
Two web servers cannot be active on the one port at the same time
this code for apache & nginx:
or
if error journalctl -xe used this code
sudo apt-get install psmisc
sudo lsof -t -i tcp:80 -s tcp:listen | sudo xargs kill
Virtual Host configuration might cause this error
I solved this same problem by configuring my virtual host .conf files properly.
I created a virtual host & then removed the exapmle.conf file form /etc/apache2/sites-avalable/ but I didn't deleted the examle.conf file from /etc/apache2/sites-enabled/ for this reason i was getting this error.
Then I removed the example.conf file from both the folders( ../sites-enabled & ../sites-available ) and solved this issue.
If you tried to setup any virtual host recently, then try this solution.
Best of Luck
Kill the running process on the port. Hope it will work!
sudo apt-get install psmisc
sudo fuser 80/tcp
sudo lsof -i tcp:80
sudo lsof -i tcp:80 -s tcp:listen
sudo lsof -t -i tcp:80 -s tcp:listen | sudo xargs kill
Go
sudo nano /etc/apache2/apache2.conf
remove this line:
Include /etc/phpmyadmin/apache.conf
Then
service apache2 start/restart
This problem may be a result of some configuration files in apache missing. One of the solutions would be to purge the apache2 file.
You can type:
sudo apt-get purge apache2
Then reinstall apache2 by typing:
sudo apt-get install apache2
As stated in the error message, we just have to execute :
systemctl status apache2.service
or
journalctl -xe
And you will have more detail about the error (line of the error, or command misspelled, or module not included in the configuration, ...) :
for example you can have following detail Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration ==> you then need to execute a2enmod ssl, and then execute service apache2 restart
Also I notice a difference between service apache2 reload and service apache2 restart commands. In case of persisting errors you should execute service apache2 restart, and then execute journalctl -xe.
You type
sudo netstat -pant
You check are you using port 80. If used, `
sudo service 'service_name' stop
and
sudo service apache2 start
The problem is because some configuration files are deleted.
You can use the following command to replace configuration files that have been deleted, without purging the package:
sudo apt-get -o DPkg::Options::="--force-confmiss" --reinstall install apache2
execute sudo service apache2 status and check the result. it might be trying to bind to a port that is already in use
I'm trying to start the rabbitmq-server using:
me#me:~$ sudo invoke-rc.d rabbitmq-server start
...and when I try to check if it is running I get:
me#me:~$ sudo systemctl status rabbit-mq-server
● rabbit-mq-server.service
Loaded: not-found (Reason: No such file or directory)
Active: inactive (dead)
What is the missing file or directory?
Alright, well...I feel really dumb.
me#me:~$ sudo systemctl status rabbit-mq-server
Should have been:
me#me:~$ sudo systemctl status rabbitmq-server
I am trying to setup OpenStack on Ubuntu 12.04 using devstack. Now, the error I am getting is:
Setting up rabbitmq-server (2.7.1-0ubuntu4) ...
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.
invoke-rc.d: initscript rabbitmq-server, action "start" failed.

Errors were encountered while processing:
rabbitmq-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
++ err_trap
++ local r=100
++ set +o xtrace
stack.sh failed
Any idea why am I getting this error?
I had this issue twice, when either hostname or ip address in the hosts file didn't match.
Therefore, check that you provide the correct ip address and hostname in the /etc/hosts file
Run sudo cat /etc/hostname to see your hostname
Output:
yoursite
Run sudo nano /etc/hosts
File contains:
127.0.0.1 yoursite
As you see from cat /etc/hostname, hostname is the same as in the /etc/hosts:
Run sudo rabbitmq-server start to start the rabbitmq-server
Try deleting the folder /var/lib/rabbitmq and re-running ./stack.sh
If that doesn't work either, run the following after stach.sh fails:
chown -R rabbitmq:rabbitmq /var/lib/rabbitmq
chown -R rabbitmq:rabbitmq /var/log/rabbitmq
service rabbitmq-server restart
and check the status of rabbitmq using "rabbitmqctl status"
Similar thing happen to me. Rabbit depends on being able to resolve a hostname, run this:
echo "127.0.0.1 $(hostname -s)" | sudo tee -a /etc/hosts
This way works for me.
First go to
sudo vim /etc/hosts
and set
127.0.0.1 <hostname>
then open firewall
sudo rabbitmq-plugins enable rabbitmq_management
sudo service rabbitmq-server restart
For a clean environment, this will not happen. You must run devstack for several times, and one of them failed but you didn't get it cleaned.
run command pf -ef | grep rabbitmq, kill all rabbitmq processes. then it would be fine to run ./stack.sh
it is highly recommended to run ./unstack.sh && ./clean.sh before ./stack.sh
Just to be sure, take a look to your local network
ip add
If there's no lo network, then you should enable it:
ifconfig lo up
Then restart the server again and let's see if it works again now
systemctl start rabbitmq-server
I had the same problem though my /etc/hosts and DNS were OK. I suspect that SystemV init script was started too early when the network was not ready yet. I rewrote the startup script to systemd on CentOS 7.8 and it seems to work well now.
