Have you also check the necessary apache directories in /etc and /var/log/
were installed as they should and something did not go wrong with the
installation of the package?

I wonder if some configuration files are missing, or the IP address/port
apache is configured to bind to is already taken by another process.

Try 'systemctl -l status apache2' and also check your '/var/logs/apache2/
error.log'.

Also run '/usr/sbin/apache2ctl configtest' and check it returns "Syntax OK",
otherwise follow any configuration errors it reports.

Thank you Michael for your response.

- no error during compilation and installation
- /var/log/apache2 and /etc/apache2/httpd.conf are in the right place
- by default in httpd.conf:
User apache
Group apache
- User and group for /var/www -> apache:apache
- /usr/bin/apache2ctl configtest returns nothing
- when trying to start apache2.service, i get this :
apache2.service: start operation timed out. Terminating.

Cheers,

OK

Check ownership of files in /var/log/apache2/

Apache will need to be able to write to them.

OK

Hmm ... it should return Status OK, or 0.

It is missing something, can't connect to the IP/port it needs, or there's a
file missing. What is the output of:

'systemctl -l status apache2'

Also set "LogLevel info" (or debug) in its config file and restart it to see
what the apache error log reveals.

Inside apache2, root:root and the files are empty.

I changed the ownership of the files into apache2 to apache:apache
No change. apache2 still fails.

I don't find any "LogLevel info" in /etc/apache2/httpd.conf
/var/log/apache2/error_log is empty.

Please take a look here to see what the httpd.conf should look like and if
there is no LogLevel directive add it yourself:

https://wiki.gentoo.org/wiki/Apache#.2Fetc.2Fconf.d.2Fapache2

Unfortunately I do not have access to an apache installation to compare notes,
but the above Wiki page should help with this. When troubleshooting similar
problems in the past I would run apachectl in a terminal and keep an eye in
the error.log to see what was being printed out.

The fact '/usr/bin/apache2ctl configtest' returns nothing makes me wonder if
all is well with the file /usr/bin/apache2ctl. Check:

which /usr/bin/apache2ctl
which /usr/bin/apachectl

to see which command exists in your installation.

After you are able to start it manually, you can edit your systemd service
file accordingly.

first of all, gentoo does install with a service file:

[root@noela:~]# equery f apache | grep systemd | grep service
/lib/systemd/system/apache2.service

also, I feel the way apache works is indifferent to distro or os. i
mean, it makes very little difference as far as apache goes if you have
openrc or systemd. in the end its just a shell script to apachectl
start|stop|restart||configtest. Get a grip on logging. On how the system
logs, and how apache logs. check /etc/conf.d/apache2 which establishes
the parameters with which apache starts.

Gentoo did not install any apache2.service.
I had to manually edit one and those found on the net don't work.
Have you got one i could use ?

thanks in advance.

GOOD NEWS ! i can start apache2ctl manually by #/usr/bin/apache2ctl
I get the warning message :
AH00558: apache2: Could not reliably determine the server's fully qualified
domain name, using 127.0.0.1. Set the 'ServerName' directive globally to
suppress this message
But, apache2 is working as i stay localhost.

So, by editing minimal apache2.service :

[Unit]
#Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target
#Documentation=https://httpd.apache.org/docs/2.4/

[Service]
#Type=forking
#Environment=APACHE_STARTED_BY_SYSTEMD=true
ExecStart=/usr/sbin/apache2ctl
ExecStop=/usr/sbin/apache2ctl graceful-stop
ExecReload=/usr/sbin/apache2ctl graceful
KillMode=mixed
#PrivateTmp=true
Restart=on-abort
TimeoutStartSec=5
[Install]
WantedBy=multi-user.target

#systemctl start apache2 works,
but #systemctl stop apache2 fails and is waiting for something....
So i can't reboot as apache2 is not stopped... :-(

Not perfect, but it is going...

Yes, you need to configure the apache files to specify IP address to listen
to, webroot, etc. for each host you want to serve files from.

Fix this by adding the "start" subcommand:

ExecStart=/usr/sbin/apache2ctl start

Nothing happens and system's waiting for something indefinitely ... (file
attached)

The same with ExecStart=/usr/sbin/apache2ctl stop.

So, i found a very very ugly way to make it working.

I wrote a micro bash shell script : /usr/bin/op_apache

!/bin/bash
case ${1} in
"start")
apache2ctl
;;
"stop")
#the ugly way... Don't repeat !
killall apache2
;;
esac

And i launch the script in apache2.service

#Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target
#Documentation=https://httpd.apache.org/docs/2.4/

[Service]
Type=forking
ExecStart=/usr/bin/op_apache start
ExecStop=/usr/bin/op_apache stop

[Install]
WantedBy=multi-user.target

So, waiting for better, it works !

Hi Michael, Alexandru and all gentoo users,
Thanks a lot for having helped me !

Cheers !
