Что делать, если не запускается апач?
Апач перестал запускаться, в логе что то про конфиг test, но его нету!

Где-то в конфигурации апача ошибка.
Просмотрите errorlog — там может быть больше информации, например в какой строке.
У вас конкретно ошибка с MPM модулем — или для него недостаточно параметров, или вы апгрейдили апач, и конфиг остался от старого, в котором опции могут идти в некорректном порядке (например блоки virtualhost до блоков с погрузкой модулей)
Проверьте конфигурацию файлов, можно еще погуглить. Если все плохо — выложите конфиги сюда, тогда можно будет подсказать конкретнее. Потому что вариантов, что вызвало ошибку может быть много.
Пригласить эксперта
apt-get purge apache2 && apt-get install nginx -y
AH00534: apache2: Configuration error: No MPM loaded.
The Apache error log may have more information.
Action 'configtest' failed.
Говорит о том, что провален тест корректности конфигурации. Если Вы выполните в консоли команду configtest, то она скажет Вам где в ваших конфигах ошибка.

Try checking is sites enabled in the server.
# apache2ctl -S
Also please copy last 20 lines in Apache error.log file.
This is not a good practice. I would suggest you to install Apache on a server and rsync /var/www folder and Apache config folder instead of sync Apache folder. If you want a high availability why not install load balancer? Haproxy would be a great option.

try
sudo systemctl start apache2
That will probably error, then do
journalctl -xe
to see what it says is the issue.

Wish I could be more precise, but this Linux isn’t familiar to me.
When apache fails to start, i always run the equivalent the command to tell apache to «run a syntax check for config files».
In CentOS and the RedHat family of Liux distributions, this command «service httpd configtest».
Alternatively, try «apachectl -t» or «httpd -t» I got that from the output of «apachectl -h».
The main point is that it will run through the process of loading all the config files but not actually go to running. If you recently made a change but mistyped something, or some detail that it is pulling in is not able to be found, this will give show you the problem and then you can take it from there.
If you get «Ok», syntax is valid and what it wants to read in can be found so you can eliminate that as the problem. So you move on trying to start the service

Check Apache error log in /var/log/apache2/ location. If not in this location check the system logs. It should write to the system log. Share your Apache site config file in sites_enabled location.
Did you enable a new site? Any changes made to Apache config files?

Not accessing an Ubuntu system to test at the moment, but I think
BASH
apache2ctl configtest
is the command that would be equivalent.

Not a new site, it is out backup production server that has a rsync command to copy the apache2 folder but stopped working suddenly yesterday.
I have deleted the apache2 folder ran the rsync copied back the apache2 folder from the production server but still not working, and the production server is running apache2 fine without an issue.
Also, I was reading into this issue, and a few people have said to do the command «sudo apt-get -o DPkg::Options::=»—force-confmiss» —reinstall install apache2″ is that a command I should try or any recommendations on what I could do?

So this is a replica of production server? You cannot just clone production as it is. I’m not sure what you want to archive in here. I would suggest to check hostname and hosts files. Let me know detail what you want to archive so I can help more

This is the command we run from the production to the backup »
rsync -raz —delete root@our IP Address :/etc/apache2 /etc/ && /usr/sbin/service apache2 reload
We would fail over if there is ever an issue on the main server.

Your rsync
Text
rsync -raz --delete root@our IP Address :/etc/apache2 /etc/ && /usr/sbin/service apache2 reload
isnt copying the ssl certs, if this the rsync command.
If you wanted to have them copied over you would include the certificate path in your rsync, which you can find in the /etc/apache2/sites-enabled/sitename.conf file under SSLCertficateFile and SSLCertificateKey
You also might not have correct apache mods enabled on the backup server.

Found the issue with apache2, it was one of the sites .conf that needed to be fixed and after that was done I was able to get apache2 back up and running.
The
apache2ctl -S command helped me find the error log since it had a different name which led me to the logs to fix the one site that was causing the issue.

Use the commands
a2ensite (or a2dissite) [ [-q|—quiet] site] to enable or disable virtual hosts in Apache2.
To figure out which sites you have enabled, use:
# ls /etc/apache2/sites-enabled/
the directory above automatically adds and removes sym-links for your enabled sites, which makes it easy to check which sites are currently enabled.
Next, attempt to restart Apache2 using:
# apachectl restart
Once Apache2 is restarted, check its status with:
# apachectl status

libapache2-mod-qos – это один из модулей Apache для защиты от атак Slowloris (разновидность DoS атак).
QS_SrvMinDataRate – один из параметров мода libapache2-mod-qos. Он прописывался в файле /etc/apache2/mods-available/qos.conf и до недавнего времени прекрасно работал.

Итак, синтаксическая ошибка в пятнадцатой строке файла /etc/apache2/mods-enabled/qos.conf, Apache не знает больше директиву QS_SrvMinDataRate.
Уже 20 марта 2015 года на дебиановском баг-трекере появилось сообщение о «баге» и с тех пор оно только обрастает подтверждениями https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=780832.
В чейнджлоге mod_qos были найдены строки:
- Experimental: mod_qos compiles with Apache 2.4
* QS_SrvMinDataRate is not available (does not work, use mod_reqtimeout
instead)
* QS_Srv* directives shall not be used (connection cleanup takes
very long)
Разберёмся сначала с первой: QS_SrvMinDataRate недоступен (не работает, используйте вместо него mod_reqtimeout.
Ну с этим всё просто:
a2enmod reqtimeout service apache2 restart
Для настройки mod_reqtimeout нужно редактировать файл /etc/apache2/mods-enabled/reqtimeout.conf
vim /etc/apache2/mods-enabled/reqtimeout.conf
Вопрос в следующей фразе: Директивы QS_Srv* не должны использоваться (очищение соединений проходит очень долго) — я до сих пор не понимаю, эта проблема уже была устранена в последующих версиях или нет? Подскажите, кто знает.
