I followed the steps mentioned in the link: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/ to install and start the mongodb server in CentOS 8 server. After completing the steps when i try to execute "sudo systemctl start mongod" command to start the mongodb server, I am getting the error mentioned in the below screenshot.
error on executing "sudo systemctl start mongod" command
Below is the screenshot of the stack trace when I execute "journalctl -xe".

Tailscale version 1.22.0
Your operating system & version Debian bullseye 11
version
Hello sir, could you guide me how to start tailscaled.service. i got an error message like this :
failed to connect to local tailscaled; it doesn’t appear to be running (sudo systemctl start tailscaled ?)
And when i try to run this command sudo systemctl start tailscaled. I got another different error :
Job for tailscaled.service failed because the control process exited with error code.
See “systemctl status tailscaled.service” and “journalctl -xe” for details.
Thanks
The journalctl output it suggests to run would tell the error it is experiencing. I'd recommend running:
journalctl -u tailscaled --since="2 hours ago"
I have already tried it with the following thread but it didn't help me:
ERROR: child process failed, exited with error number 1,mongodb
Tried that:
sudo mongod --fork --config /etc/mongod.conf --logpath /var/log/mongodb/mongod.log
Result:
forked process: 2887
ERROR: child process failed, exited with 48
To see additional information in this output, start without the "--fork" option.
Tried the following as well:
sudo systemctl start mongod
One of the lines in the error message say:
ERROR: child process failed, exited with 14
Would appreciate any help. mongod was working pretty well until I have started trying to implement a replica set.
Use this command on the terminal:
sudo mongod --dbpath /System/Volumes/Data/data/db
It should start the MongoDB server and allocate a port for it. You can exit out of the server and then try the command again and it should work.
when I try to boot Ubuntu, it never finishes the boot process because it appears the message "Failed to start PostgreSQL Cluster 10-main." I also get the same message with 9.5-main. But lets focus on 10.
When I execute:
systemctl status postgresql#10-main.service
I get the following message:

I got this error from one day to an other without touching anything related to Database Servers.
I tried to fix it by my self but nothing worked
Writing the command
service postgresql#10-main start
I get
Job for postgresql#10-main.service failed because the service did not take the steps required by its unit configuration
See "systemctl status postgresql#10-main.service" and "journalctl -xe" for details.
Running this two command I get the message from the beginning.
Anyone has an idea of what is happening? How I can fix it?
I had same issue, I followed below steps,
Error status :
pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
10 main 5432 down postgres /var/lib/postgresql/10/main
/var/log/postgresql/postgresql-10-main.log
Applied Solution :
sudo chmod 700 -R /var/lib/postgresql/10/main
sudo -i -u postgres
postgres#abc:~$ /usr/lib/postgresql/10/bin/pg_ctl restart -D /var/lib/postgresql/10/main
After Solution status :
pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
10 main 5432 online postgres /var/lib/postgresql/10/main
/var/log/postgresql/postgresql-10-main.log
as mentioned by #gruentee in comment above,
/usr/lib/postgresql/10/bin/pg_ctl restart -D /var/lib/postgresql/10/main -l /var/log/postgresql/postgresql-10-main.log -s -o '-c config_file="/etc/postgresql/10/main/postgresql.conf"'
started the postgresSql DB. Dont forget to
sudo -i -u postgres
before issuing above command
I was facing the same challenge, I try a lot of methods but none work for me till I try these commands below
sudo apt-get -y install postgresql
sudo systemctl start postgresql#15-main.service
pg_lsclusters
then everything started working fine, but please the version of postgresql i'm using is 15 that's you are seeing 15 in the second command so in your case you substitute it with the version you are using
While trying to run a puppet update form a node:
sudo /opt/puppetlabs/bin/puppet agent -t
I get an error:
Error: Could not retrieve catalog; skipping run
Error: Could not send report: Connection refused - connect(2) for "puppet" port 8140`
Elsewhere indicates this is likely a problem with the puppetserver service, and suggests to reboot the server. Restarting didn't help, and when I try to restart the service I get failure:
~$ sudo service puppetserver restart
Job for puppetserver.service failed because the control process exited with error code. See "systemctl status puppetserver.service" and "journalctl -xe" for details.
I've looked at these logs, and as a puppet/linux noob, I'm not sure what to do next.

The puppet master communicates with the other node using port number 8140.
I don't think a restart will help, since this looks like a connection issue between the server and the node.
please try the following -
first make sure that the puppet master is actually listening on port 8140. run the following command on the puppetmaster -
netstat -ntlp | grep 8140
this command should return something like this -
tcp 0 0 0.0.0.0:8140 0.0.0.0:* LISTEN 1783/puppetmaster
If you don't get the same output, your puppetmaster is not listening, and therefore can not compile catalogs for the node.
Try checking the puppet master log at /var/log/puppetmaster.log
check that the node can communicate with the puppetmaster on the relevant port. you can check this quickly with the telnet command. run this on your node -
telnet < puppetmaster ip address \ dns name> 8140
you should get something like -
Connected to <puppet-master-IP/DNS-name>
Escape character is '^]'.
if you don't get this output, this means that something is blocking you from accessing the puppetmaster. try opening the port in your firewall to access the puppetmaster.
if you're still stuck try using the --debug flag for verbose output and edit your question.
Could be 2 things: (1) in puppet.conf you have configured more memory than you have on your machine. Or (2) You installed both apt-get install puppetserver and apt-get install puppet.
If you get failed to start puppet.service: unit not found. error on slave machine while connecting to puppet.
Close the putty and then again open and connect it.The issue wont come while starting putty on slave.
The error occurs because there is not enough RAM and to fix the error, open the Puppet server configuration file:
sudo nano /etc/sysconfig/puppetserver
And reduce the amount of allocated RAM for the Puppet server (for example, I specified 512m instead of 2g):
JAVA_ARGS="-Xms512m -Xmx512m"
Now let’s start the Puppet server:
sudo systemctl start puppetserver
I have installed MongoDB 3.0.6 in Ubuntu 15.04 using the following commands.
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/3.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
sudo apt-get update
sudo apt-get install -y mongodb-org
In the end in the installation process I got this:

sudo service mongod start
And the error is

Now when I run:
sudo systemctl status mongod.service

Someone please help, I am new to Ubuntu and MongoDB and I am not getting what is the problem.
There is a log file: /var/log/mongodb/mongod.log
In the log I've found the following:
Failed to unlink socket file /tmp/mongodb-27017.sock errno: Operation not permitted
Most probably this was from previous MongoDB version. I deleted the file (rm -rf /tmp/mongodb-27017.sock) and finished the installation:
apt-get install mongodb-org
Now it works. :-)
Recently i ended up with same issue and i tried all the possible solutions explained up here. But it didn't worked out for me. I was getting the below error.
# sudo service mongod restart
Restarting mongod (via systemctl): Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details. [FAILED]
Eventually i figured out the solution which worked for me.
I went to /run/mongodb folder and deleted the file called mongod.pid. Then tried to restart the mongo using # sudo service mongod restart and it's worked!
My log said:
[initandlisten] Found an invalid index { v: 2, key: { version: 1 }, name: "incompatible_with_version_32", ns: "admin.system.version"
so:
$cd /var/lib
$sudo rm -rf ./mongodb
$sudo mkdir mongodb
$sudo chown -R mongodb.mongodb mongodb/
$sudo service mongod restart
and then all worked fine.
sudo nano /etc/systemd/system/mongodb.service
[Unit]

ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

sudo systemctl start mongodb
sudo systemctl status mongodb
sudo systemctl enable mongodb
Is job!
The first thing you should check is a mongodb log file located at /var/log/mongodb/mongod.log
Look for the line with status E containing words like 'failed', 'fatal', etc.
Make sure that the /data/db directory exists
Make sure your user have write privileges in that directory:
$ sudo chown id -u /data/db
Execute mongod
If you still have problems and if the file /data/db/mongod.lock exists, remove it and execute mongod --repair.
I removed the mongodb lock file-
sudo /data/db/mongod.lock
Then restarted the mongodb
sudo service mongod restart
This solved the issue.
I was having the same issue, after searching I got the answer that, when I executed
sudo service mongod restart
I changed the permissions from user mongodb to root of the database folder, so the service was not able to read the data.
So to solve I just reverted the permissions back to the user mongodb
sudo chown -R mongodb:mongodb /path-to-db-folder
sudo service mongod restart
