I have installed and configured and also used TV the first time today in Nvidia jetson Xavier,
but after restart Im getting this issue:
teamviewerd.service: Can't open PID file /var/run/teamviewerd.pid (yet?) after start: No such file or directory
Please tell me why and how to fix it, it is of extreme importance !
I use TeamViewer to connect to a machine (Ubuntu 20.04) that not always have a graphical user session started and I noticed that even with teamviewerd running the machine is offline.
I fixed the problem running:
sudo teamviewer setup
From teamviewer --help:
teamviewer setup Configure headless modes (non-gui/console)
Without running this, the only way for me was to start manually a graphical user session and open the TeamViewer GUI on the host I wanted to use.
Make sure you enable/start gdm.service or another supported login manager
Found this question via a search when facing the same issue on Fedora 30 x86_64.
Solution for me was to edit /etc/systemd/system/teamviewerd.service and comment out the line that says:
PIDFile = /run/teamviewerd.pid
So it reads:
# PIDFile = /run/teamviewerd.pid
(or whatever PIDFile it specifies)
then run:
systemctl daemon-reload
systemctl start teamviewerd
systemctl status teamviewerd
Serve is a library that allows you to serve your React build folder similar to npm start
Create an app with npx create-react-app .
Then run the following the following to create build and serve the app
npm run build
npm install -g serve
serve -s build
It works perfectly, only how does one kill the listening on port 5000
control c brings back the suspended terminal prompt and lsof -iTCP -sTCP:LISTEN -n -P indicates that it is no longer listening on port 5000.
pkill -9 node does not do it.
Even though it appears not to be listening on port 5000 I can go to localhost:5000 and it serves up the file as though it were listening on 5000;
NOTE: this happened on MacOS
The reason you're still seeing content even after the server is killed is because you're using a Service Worker. Service Workers will cache content so that even when a user is offline, they can continue to use your web app. What you're experiencing is the intended functionality.
You can make your life a little easier by using Incognito Mode when working with service workers, so you can easily reset your browser and thereby clear any active service workers.
I'd recommend you read more of the Workbox documentation as I can see you're working with that framework.
Another way to stop a service worker is through the Chrome Dev tools panel.

Disable Selinux!
Configure SELINUX=disabled in the /etc/selinux/config file and then reboot!
Be ensure the selinux is disabled by the command getenforce.
$ getenforce
Disabled
zhe.
Correctly installing the enterprise edition depends on the correct system prerequisites. Anyway I suppose you're still on the bootstrap node so I will give you some path to succed in your current task.
Run the script as root or as a user issuing sudo dcos_generate_config.ee.sh
The script will also generate the config file automatically; if you want to use your own configuration file then create a folder named genconf and put it inside before running the script. You should changes the values inside <> with your specific configuration. If you need more help for your specific case send me an email to infofs2 at gmail.com
What I'm trying to do:
Make screenshots of desktop and running program (Firefox Webdriver with Selenium, if it's important) in daemon (celeryd) in auto mode.
And I need desktop manager to be running, this is mandatory requirement. Currently I'm trying to use Fluxbox but I can switch to any other manager.
Current progress:
I can start X-server (Xvfb) in daemon and start Selenium Webdriver. Fluxbox start succeeds when I try to make it from terminal, but fails in daemon with following errors in log:
Can't create directory
Failed to load database:
Failed to load database:/init
Retrying with: /etc/X11/fluxbox/init
I tried to specify init-file directly, but Can't create directory error still exists and Fluxbox fails to start.
This might be daemon-mode restriction.
Question:
Is it possible to run any desktop manager inside daemon?
If yes, then how can I do this?
Something that I've noticed recently on two different machines is that Apache2 installed via MacPorts seems to have stopped launching when I boot up. The honest truth is that I can't swear it did so before, but it's something I think I'd notice because installing the LaunchDaemon is part of my install process. In fact, if I try to reload the LaunchDaemon, it fails:
$ sudo launchctl load -w /Library/LaunchDaemons/org.macports.apache2.plist
org.macports.apache2: Already loaded
Unless I start Apache manually (using sudo apachectl restart), grep'ing for either "apache2" or "httpd" in my process list only produces this:
$ sudo ps -ef | egrep "apache2|httpd"
0 52 1 0 0:00.06 ?? 0:00.08 /opt/local/bin/daemondo --label=apache2 --start-cmd /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper start ; --stop-cmd /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper stop ; --restart-cmd /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper restart ; --pid=none
1410639199 6960 6792 0 0:00.00 ttys001 0:00.00 egrep apache2|httpd
Looks like the daemon itself is in place, but no executable. As far as I know/can tell, the relevant executables (httpd and apachectl) are executable by everyone.
Has anyone else noticed this? Any ideas?
UPDATE
As requested below, I did execute launchctl list. The list is long and I'm not sure how to snip it, but suffice to say that no org.macports.* items are listed. That in itself is interesting because my MySQL daemon is loaded the same way. It works, but also doesn't appear in the list. Let me know if the entire output is really needed.
UPDATE
I assumed that I had executed launchctl list under sudo, but prompted by mipadi's comment below, I tried again ensuring that I did so and I assumed incorrectly. When executed under sudo, the MacPorts items appear:
51 - org.macports.mysql5
52 - org.macports.apache2
I'm not sure whether that will help, but it's a little more info nonetheless.
UPDATE
I've asked a different, but related, question at LaunchDaemons and Environment Variables. I'll update both questions as I learn more.
UPDATE
Today, based on mailing list input, I tried using a wildcard home directory. Academically, it's a little more inclusive than I'd like, but the practical reality is that I'm the only one using this computer; certainly the only one who'd have Apache config files laying around.
Include "/Users/*/Dropbox/Application Support/apache/conf.d.osx/*.conf"
Include "/Users/*/Library/Application Support/MacPorts/apache/conf.d/*.conf"
Unfortunately...
httpd: Syntax error on line 512 of /opt/local/apache2/conf/httpd.conf: Wildcard patterns not allowed in Include /Users/*/Dropbox/Application Support/apache/conf.d.osx/*.conf
I found my answer to this problem here:
https://trac.macports.org/ticket/36101
"I apparently fixed this when changing my local dnsmasq config. In /etc/hosts I added my servername (gala) to the loopback entry:
127.0.0.1 localhost gala
and then I changed ServerName in /opt/local/apache2/conf/httpd.conf to match:
ServerName gala
Apache now starts at boot for me."
Since I now know why Apache has stopped loading on startup, I'm going to articulate that answer and mark this question as answered. The reason Apache has stopped launching on boot is that I'm trying to share an httpd.conf file across systems. The config file needs to Include files from directories that exist within my home directory. Since the home directory is different on each machine, I was trying to reference the ${HOME} environment variable.
This works fine when manually starting after the machine is booted, but fails on startup because the environment variable isn't yet set. As mentioned above, see this question for more information.
Rob:
Had the same problem: "sudo launchctl load -w ..." started Apache2 while I was logged in, but did not work during startup (the "-w" should have taken care of that). Also, as you noticed, the daemon seems to be registered with launchctl. It will show up with "sudo launchctl list" and another "sudo launchctl load ..." will result in the error message.
I played with "sudo port load apache2" and "sudo port unload apache2", but could not get httpd running on reboot.
In the end, I got rid of the MacPorts startup item: "sudo port unload apache2", checked with "sudo launchctl list" that org.macports.apache2 is no longer registered for startup.
Afterwards, I followed the steps on http://diymacserver.com > Docs > Tiger > Starting Apache. I only had to adapt the path from /usr/local/... to /opt/local/...
Now the MacPorts Apache2 is starting fine with every reboot.
Good luck, Klaus
I found that my MacPorts apache2 was not starting on boot because of an “error” in my httpd.conf.
I was using
Listen 127.0.0.1:80
Listen 192.168.2.1:80
Listen 123.123.123.123:80 # Example IP, not the one I was really using
And in Console.app I was seeing
4/8/12 4:59:06.208 PM org.macports.apache2: (49)Can't assign requested address: make_sock: could not bind to address 192.168.2.1:80
4/8/12 4:59:06.208 PM org.macports.apache2: no listening sockets available, shutting down
4/8/12 4:59:06.208 PM org.macports.apache2: Unable to open logs
I tried adjusting permissions on all the log folders (despite the fact that logs were being written just fine when I manually started apache2) and that didn't help.
Even though the Apache Documentation for Listen clearly states
Multiple Listen directives may be used to specify a number of addresses and ports to listen to. The server will respond to requests from any of the listed addresses and ports.
I decided to try switching back to just using
Listen 80
And after doing so apache2 is starting on boot with no errors or warnings.
If you're using Subversion with Apache, you may find that Apache is not starting because the mod_dav_svn.so file has moved to /opt/local/libexec. You'll need to adjust your Apache startup files to account for the new location of this file.
In newer versions of MacPorts you can run sudo port load apache2 to instruct MacPorts to take care of the launchctl setup and automatically start the process. To stop the process run port unload.
After loading check /opt/local/apache2/logs/error_log for errors, including configuration issues.
In addition to my previous answer I have also found that sometimes Apache fails to start because something else with the system is not yet ready.
On one OS X Server machine I also use the DNS to create a “internal only” DNS name for the machine and that name is used in my Apache configuration. Sometimes when Apache tries to start the DNS server is not yet ready and Apache fails to load because the hostname isn’t valid.
I have also seen this on other non-Server systems without local DNS as well where something else required by Apache must not be ready yet.
One thing that has worked is to edit the apache2.wrapper located at /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper that MacPorts’ daemondo uses to start up Apache.
Edit the Start() function to add a sleep command to wait a bit before launching Apache.
Original (Lines 14-17 on my machine)
Start()
{
[ -x /opt/local/apache2/bin/apachectl ] && /opt/local/apache2/bin/apachectl start > /dev/null
}
With wait time added
Start()
{
[ -x /opt/local/apache2/bin/apachectl ] && sleep 10 && /opt/local/apache2/bin/apachectl start > /dev/null
}
