neo4j server is not restarting or stopping - neo4j

I am getting the following errors and I dont know how to restart the server .I tried multiple times but I get the same error all the time.How can I stop and restart the server.I really appreciate any help.
./bin/neo4j start
displays:
/usr/local/neo4j/data/log/console.log: Permission denied
process [11825]... waiting for server to be ready.. Failed to start within 120 seconds.
Neo4j Server may have failed to start, please check the logs.
sudo ./bin/neo4j start
displays:
Another server-process is running with [ST=ESTABLISHED], cannot start a new one. Exiting.

The exception you get is because another server is running.
Also, there is another exception, you don't have write access in the folder for the logs.
Check if http://localhost:7474 is displaying the neo4j web browser.
If yes, locate the location of the running database :
Then go to the location and stop the db, eg based on the image :
cd /Users/cw/_graphs/tests
./bin/neo4j stop
If it is not working, try to kill the process :
sudo htop
kill -9 10522
And try to run your new database. And make sure you have the right permissions for the stores and logs.

Neo4j goes off on CentoOS server

My neo4j stops by itself after some time on my Godaddy CentOS server. I have to run neo4j start before it come up again.
I do not know if godaddy server go to sleep mode after some inactivity time but you could try to enable the service to start it when the server spin up again.
systemctl enable neo4j
this command might need sudo permission

neo4j community edition 2.1.6 server process running even after server stop command executed

I know at least a few of us had this issue come up...I am issuing the command to start the server and yet it tells me that a server process is still running at 17922...I then try the following:
./bin/neo4j status
And it tells me: "Neo4j Server is not running"
Then I issue the command to start a new server: ./bin/neo4j start
and I get the following:
Another server-process is running with [17922], cannot start a new one. Exiting.
Not looking to run multiple Neo4J servers, so I'd like to stop whatever is running in the background.
Seems the process is not nicely responding for whatever reason. You might want to inspect the log files (data/log/* and data/graph.db/messages.log) to get more insight.
To terminate the process use kill 17922. If that does not help, kill -9 17922.

wont let me run rails s because there is another server running but i don't know how to access that server

How do I close the old server even though I can't see its terminal anymore so I can access my project?
I tried exiting out of the program then exiting back in but nothing would work.
keeps bringing up this error:
A server is already running. Check C:/Users/Nathan/Documents/Aptana Studio 3 Workspace/Nathans First project/tmp/pids/server.pid.
Exiting
Use netstat to find the process id running on the port the server has bound to. Then kill that process.
run cmd.exe as administrator.
To list process
C:\> netstat -a -b
Find the process id that is bound to the port your server runs on
C:\> Taskkill /PID <the process id (pid) of the server> /F
can you visit your app from the url 127.0.0.1:3000, 3000 is the port your app suppose to be running.
Case 1. if you can visit at the location, then use the activity monitor or something like that , find the ruby process and kill it.
Case 2. if you can not visit, then just delete the file C:/Users/Nathan/Documents/Aptana Studio 3 Workspace/Nathans First project/tmp/pids/server.pid will be fixed this problem. It is cause by a abnormal server exist like you shutdown your computer without shutdown the server normally.
Check you tmp/pids/server.pid file under your app which wil have the process id of other instance of rails server currently running. First kill that process using kill -9 process_id in your linux terminal. Check how to kill a process for your particular version
Delete the server.pid file in the C:/Users/Nathan/Documents/Aptana Studio 3 Workspace/Nathans First project/tmp/pids/ directory and restart the server.
Make sure you close the command prompt window and open it again before restarting the server.
Hope this helps!

Neo4j Server Closing for no Reason?

I have a small database that was working fine just a day ago, but now, when I try to start it, the console claims that it succeeds in opening, but the web server hangs.
lsof -i | grep 7474
states that neo4j is listening to the port, and "close_wait"-ing, which I'm told means that the server side shut it down.
The only new error I get is that logback.groovy is missing, along with logback-test.xml, which is very odd, because I set logging to false in the neo4j config file.
Any idea what could be happening? Any one else encounter this problem?
Check messages.log for more detail about the shutdown reason.

Problem stopping/starting MySQL Workbench

I've installed the MySQL workbench version 5.2.34 and having problems creating a local connection. I'm getting an error saying "Can't Connect to MySQL Server on 127.0.0.1'(10061)" when i try connecting to Localhost on Port 3306. I tried restarting the service but i don't have the option to stop/start/pause or resume using Windows 7. The status is just set to "starting". I also tried "net stop mysql" from the command line in DOS but get the following error: "The service is starting or stopping. Please try again later"
Does anyone know if this is another bug in the Workbench or is there a quick solution to get around this?
You can restart mysql from services. Also, check error log (by default, on Windows 7 machine it's under ...ProgramData\MySQL\MySQL Server [version]\data
Sounds like a problem with MySQL itself starting up. You may have to kill the mysqld process if nothing else gets it into a started or stopped state, and then investigate the .err logs in your data directory.
This solution uses the window's mysql installer which you have used to install your MySQL.
Even though this post is very old, I have wasted around 2 hours and hence want to post this so that it can save someone else's time.
I have tried every other way of restartring the service, but mysql service just wont start.
Start your windows mysql installer. For me it was "mysql-installer-community-8.0.20.0"
Then remove/uninstall the SQL Server and remove all configurations
Manually delete the SQL Server folder from "C:\Program Files\MySQL\MySQL Server 8.0."
Start your mysql installer again and install the SQL Server again
You can check now that the MySqL Server has started.
