NGINX failed to work while configuring server for subdomain - amazon-web-services

Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
Prior to this prompt, the server was working fine, but when I tried to config the server for subdomain it failed to work with this error.
Also for detailed error ...

You can always check configuration errors by using this command :
nginx -T
before launch a catastrophic restart :)

You have an error unexpected end of file, check the syntax of your NGINX configuration as it is likely that you have a broken file.
The likely candidate is forgetting to close a } character.

Thank you all for your prompt response.
You've an error in your flags for alertmanager.
It appears, you should use --web.external-url rather than -web.external-url

Failed to start Redis In-Memory Data Store. Ubuntu 18.04

I am trying to install redis on my AWS server. I have Ubuntu 18.04 installed on it. I am following steps to install redis from digitalocean article.
When i run sudo systemctl status redis command i am getting below error.
screenshot
I tried to edit /etc/systemd/system/redis.service file and added Type=forking under [Service] section but still getting the same error.
Can anyone suggest me how i can get it fixed?
Thanks in advance.
Based on same digitalocean tutorial, actually it's running fine.
Run this command sudo systemctl restart redis.service, we get (showing "failed" on last line):

After searching for hours, it seems like it's some difference between systemctl & service and nothing more, but the actual redis server is running fine. Corrects me if that's not the case. Here's the link: https://askubuntu.com/questions/903354/difference-between-systemctl-and-service-commands
You can even check if redis is working fine, by redis-cli ping, should print PONG
I also encountered this problem, then I tried to check it again.
Finally, I found that when I authorized /var/lib/redis, I entered the wrong command, causing the redis account to have no access to /var/lib/redis.
sudo chown redis:redis /var/lib/redis
sudo systemctl restart redis
succeeded.

Systemctl with gunicorn permission denied

I've been working on systemctl for a while and it's just not working.
I have tested with gunicorn and it works perfectly, but when I'm doing this
systemctl daemon-reload
systemctl enable flaskapp
systemctl start flaskapp
However, I've been getting issues like this

I tried with sudo and it doesn't work either. I have searched everything online but no result. Can anyone help me with this?

docker-machine create with digitalocean driver: ssh command error

I´m using docker tools on windows.
create command was working perfectly last week and I managed to create a number of machines on Digital Ocean. Then I tried today with no success. I repeated the same command with different regions and I always get the same result:

Any help would be appreciated
Update
It´s working with ubuntu 14:
--digitalocean-image=ubuntu-14-04-x64 so it seams like a problem with the default image (ubuntu-16-04-x64)
This seems to be hitting a lot of people. TL;DR: There is a bug in docker-machine v0.12.0 and this issue can be resolved by upgrading.
Logging in to the DigitalOcean instance and running journalctl -xe provides more information:
-- Unit docker.service has begun starting up.

-- Subject: Unit docker.service has failed
-- Defined-By: systemd
-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel
The key here is docker daemon is not supported on Linux. A bug in docker-machine's version comparison code caused an incorrect systemd unit file to be produced (located at /etc/systemd/system/docker.service.d/10-machine.conf) on certain versions of Ubuntu.
A fix has been committed and a new release (v0.12.1) was made.

Does anybody know how to fix something like this, i am still newbie for setup things like this, been searching the answer but nothing similiar to me.
i just started using django and it worked using:
uwsgi --http :8080 --home /root/Env/apxweb --chdir /root/apxweb -w apxweb.wsgi
but when i started using it with nginx,
uwsgi service failure to start.
notes: nginx service worked.
Thanks Luke Dixon,
Yes the problem is within user,
I update the file like this:
/usr/bin/bash -c mkdir -p /run/uwsgi; chown root:nginx /run/uwsgi
uwsgi worked again,
i dont know if this is the correct way to fix uwsgi,
but anyway thank you very much.
