Running any of the commands varnishstat, varnishhist, varnishlog, varnishtop will give the error message as
Could not get hold of varnishd, is it running?
Below is some information for understanding.

Answer:
sudo varnishstat
sudo varnishhist
sudo varnishlog
sudo varnishtop
If you’re using Varnish utilities as unprivileged user, you’re probably missing privileges to execute some actions. For some distros, it’s enough to add yourself to Varnish’s group:
gpasswd -a my_user varnish
Then put the new group in use and at least varnishstat should work.
If sudo varnishstat doesn't help: check if varnish is started
sudo /etc/init.d/varnish start
Following worked fine for me:
sudo varnishadm
Found this thread, however the answers here did not help.
As per: http://lists.varnish-cache.org/pipermail/varnish-misc/2020-July/026914.html when you have updated the serverhostname, you need a full server reboot.

I would like to install the most recent tinyproxy version 1.11.0 on Ubuntu. How can I do that?
Unfortunetly does sudo apt update; sudo apt install tinyproxy -y; not work for me and only gives me the most recent stable version 1.10.0 from 2018.
So I tried to download and unzip the most recent version on GitHub
https://github.com/tinyproxy/tinyproxy/releases
But I couldn't get it to work properly installed yet.
What I tried so far:
sudo apt update;
... [loading the unzipped tinyproxy 1.11.0 folder via own GitHub repo]
cd OwnGitHubRepo/tinyproxy-1.11.0
sudo apt-get install build-essential -y
sudo apt install autoconf -y
autoconf
./configure
make
sudo make install
The installation seems to have been working somehow as tinyproxy -v returns: tinyproxy 1.11.0
But I now can not run following command which I would usually do:
sudo /etc/init.d/tinyproxy restart;
As there is no tinyproxy folder inside /etc/ listed yet. :/
(Also sudo lsof -i:8888 doesn't show any listing server yet)

I'm trying to run a bash script on startup as a systemd service, I'm doing this on a Raspberry Pi 4 with Raspbian Buster Lite.
I'm able to execute the bash script if I run it manually ./hls.sh and I am able to also run the service if I do sudo service tv start but the tv.service does not appear to be able to execute the bash script hls.sh on start. I did give permissions chmod 777 for both the service and the bash file as well.
Any help here would be appreciated, I've been trying to figure this out on and off for a month now.
Edit:
Using the suggestions by Carl, I modified the files. However, it still doesn't work. I noticed also that when Type=oneshot you can't do a Restart=always, and if I do a restorecon -r there's an error that says the command isn't found. Per Carl's suggestion I put everything in /opt I decided not to use the temp file suggestion because I need to have the ffmpeg output go to the same place every time (my understanding is that the other way would randomly generate a folder?).
Edit2: Issue was related to this systemd issue: https://unix.stackexchange.com/questions/209832/debian-systemd-network-online-target-not-working the workaround was simply to do RestartSec=5s under [Service]

There are a few issues with this service file. I'll address them below and then show the final solution.
Avoid putting system-level services under the /home directory. While it may work, it is not advised. There are many out-of-scope issues that could occur by doing that. Instead, consider placing the scripts under /opt, /srv, or /usr/local.
When moving the files around in a big way like this, make sure to run restorecon -r on that directory after moving it. This ensures SELinux contexts are reset to their correct values, rather than mixing the new context with the old context. This can help solve permission denied errors when SELinux is in enforcing mode.
The Restart= directive goes under [Service] not [Unit], so that should be moved there or be removed entirely. It's probably innocuous since systemd is sometimes forgiving, but the systemd.service is the one that defines that directive, not systemd.unit.
Change ExecStart= to not have & at the end. Just leave it be and run it as a normal script. Systemd will handle the rest, if properly configured.
Change ExecStop= to ExecStopPost= instead. This will allow systemd to do its normal stop behavior, which is to send a SIGTERM to the script when being asked to stop the service. After the stop has been completed (either gracefully or forcefully), the ExecStopPost= will run. Since it appears you're using it to cleanup after the script ran, that should be changed. If left as is, systemd will remove the directory then wait for the script to exit, which the script will never do since it wasn't told to, so systemd will wait the timeout period before asking the kernel to SIGKILL the script. Definitely not ideal.
A few extra directives under [Service] would solve some of the assumptions about how this service should behave.
WorkingDirectory= — so that it is defined rather than assumed. If left as default, it becomes the home directory of the User, which if also is left default, would be /root. Instead, set it to the location of the script or to /tmp if PrivateTmp=true.
User= — so that the script doesn't run as root which is the default user. I suggest nobody or whichever user you wish to have managing the ffmpeg execution. This prevents giving the script root privileges when it runs, which ffmpeg shouldn't need.
Type= — this is arguably the most important, since the script is being ran as a one-off and will then exit after succeeding; it doesn't daemonize to the background and continue running as the default simple service would. This should be set to oneshot instead so that systemd knows that; it will treat the script exiting (with a status code of 0) as a successful run of the service, and will move on.
PrivateTmp= — In most cases, this should be enabled. Only in rare circumstances should it be disabled. The default behavior is disabled. When enabled, anything the script tries to store in /tmp will actually be transparently stored in a namespaced directory called /tmp/systemd-private-xxxx-servicename.service-xxxxx/, preventing any conflicts with other files in /tmp. If you use this, I would change your ffmpeg to write to /tmp instead of managing a directory next to the script, enabling you to remove ExecStartPre= and ExecStopPost= altogether.
Make sure the ExecStartPre= and ExecStopPost= have a + prepended, that way they run as root instead of the defined User= which might not be root; this may or may not be necessary depending on your expectations with the directory. See systemd.service Table 1. Special executable prefixes for more info.
Change WantedBy=default.target to multi-user.target; it is more likely that this service is supposed to be ran for that target, rather than whatever target happens to get booted as default.
You probably shouldn't make the script chmod 777, I would go with a modest chmod 755 instead. It should only need the read and execute bits (+rx).
So without further adieu, this is the final solution:

I'm trying to set up a minecraft server to play with my friends. It's my first time doing this on linux, so I have a (I believe) small problem. I can't figure out how to set up it on my usb hard drive.

Distro is Ubuntu Server 18.04.3 LTS
I need it on usb hard drive because I have small sd card. In future I want to replace it with ssd on adpter
Ok. Thank you all for not helping me. After hours I found solution(s).
I re-created user minecraft with --system
Created group minecraft with --system
added user to group
Set home folder of minecraft user to .../.minecraft-server (when i did it on create it throwed error)
This fixed my problem with server not starting at all, but then i cannot attach to screen.
I tried -c with custom config and editing /etc/screenrc (second option totally broke screen, so I needed to reinstall it). Finally i created .screenrc in /.minecraft-server with options multiuser on and added users that can attach.
Now it's working, but I spend about 10 hours straight to fix it...
Creating user and group:
adduser --system minecraft
addgroup --system minecraft
usermod -a -G minecraft minecraft
usermod --home /home_folder minecraft
.screenrc in minecraft's home directory:
multiuser on
addacl root
addacl user1

I installed httpd 2.4.27 in CentOS 7. I configured httpd.service as systemd service. But everytime I got this error PID file /usr/local/apache2/logs/httpd.pid not readable (yet?) after start. when I start or restart httpd.service.

I found there was no use to change the permission of httpd.pid file manually, because the file will be removed automatically when service gets stopped. And new httpd.pid file will be generated once service is turned on.
Note: I see some posts saying updating /usr/lib/tmpfiles.d/httpd.conf will work. But I don't have this file since I installed apache from source. I think only 'yum install httpd' has this.
Anyone can help? I just want to have a clean service start with no error or warning. Thanks.
you can set /lib/tmpfiles.d/httpd.conf follow:
d /usr/local/apache2/logs/httpd.pid 700 apache apache
vim /etc/systemd/system/httpd.service
