General Newbie Questions

Hello everyone! My name is Onurhan, an undergrad CS student and a total newbie to Neo4j. Been trying to install Neo4j to my Windows 10.

I am following every step from here: Thanks for Downloading Neo4j Desktop - Neo4j Graph Data Platform

I navigate to the right directory, type "bin\neo4j console", then this is printed to the console:

2020-04-08 14:42:41.309+0000 INFO Neo4j Server shutdown initiated by request

Also http://localhost:7474/ gives "ERR_CONNECTION_REFUSED" on my Chrome browser. I tried it on Microsoft Edge, it's giving a similar error.

I have JDK 11.0.6 installed.

This is my second attempt to install. First time, I only downloaded "neo4j-desktop-offline-1.2.6-setup" and tried to start from there. But when I tried to start a database "Database failed to start: DB [database-da2830be-9da0-409c-a142-02b631b6b94c] 'v4.0.3' exited with status 'KILLED' " was what I got. I uninstalled Neo4j with the help of Elaine from user support, and reinstalled from above link. This is how i got here.

Thanks everyone for your help and time!

Hello,

If you have downloaded Neo4j desktop, you should simply click the executable to install it. The running of the console is if you have downloaded Neo4j Server.

Are you trying to install Neo4j Desktop?

It should create a icon on your "Desktop" that you simply click to stat Neo4j Desktop.

Hello,

I am hoping to use Neo4j for my graduation project. If Neo4j Desktop is what I need I can install it and use it.

Is server not needed to use the desktop app? I thought it was necessary because of the errors.

As you can see in the screenshot, the error is still the same. I installed Neo4j Desktop(1.2.6) and Neo4j Community Server(Neo4j 4.0.3).

At the first time I contacted you, there was only desktop application.

Is there really a problem or am I missing something? Can't be sure.

Appreciated for your help.

Forgetting, I can create a database. I create a local graph and it is also giving the same error.

Can you look at the log file for Neo4j Desktop here:

%USERPROFILE%.Neo4jDesktop\log.log

Also, hover over the three dots to the right of Sample database and select Manage and then view the log file for this sample database.

Hopefully the logs will show something useful.

Elaine

neo4j.log is the log for sample database.
All the best!

When you installed Neo4j Desktop, did you specify a different folder for the application data? In the log file, it is saying that ~/.Neo4jDesktop/neo4jDatabases does not exist?

Can you do the following:

  1. Remove all files in ~/.Neo4jDesktop
  2. Reinstall Neo4j Desktop and install it so all users on your system will have access. Use defaults for everything else.
  3. Then see if Neo4j Desktop starts and the sample database is started.

Should I leave the path for application data, as the installer suggest? It is %user_profile%.Neo4jDesktop

Yes, use all defaults, except you want all users on your system to be able to access Neo4j Desktop. This may help with permissions....

Didn't work, also I want to add that I tried it on my other pc too. That was the first time I installed Neo4j to that pc. I always registered with same information, can that result in my problem?

Can you send the logs from your recent install?

Good luck, thank you!

I am confused by the db.log. It seems to have records from the previous installation. Did you delete all files related to the previous installation?

I don't see anything alarming in the desktop log file. It didn't find a 5.1 or later version of powershell.

Can you install a later version of powershell?

And can you delete ALL files from the Neo4j Desktop installation and reinstall? I don't want to see anything in the db log file that refers to records written prior to the install of 1.2.7 of Desktop.
