Problem while installing community server edition

Hello,
Sorry, but I´m new concerning installing software in a server.
I´m trying to install community server edition in a Linux server, but I get stuck at this point, while starting neo4j from the server console. I receive two permission denied messages.
I receive this message:

/home/ubuntu$ neo4j start
Directories in use:
home: /var/lib/neo4j
config: /etc/neo4j
logs: /var/log/neo4j

/usr/share/neo4j/bin/neo4j: line 371: /var/log/neo4j/neo4j.log: Permission denied
Starting Neo4j.
WARNING: Max 1024 open files allowed, minimum of 40000 recommended. See the Neo4j manual.

Can anyone help me?

Check the permission in the log file. The Neo4j database needs to be able to read+write to the log folder. On Linux look up the commands chown and chmod

Hi Mike,
Thank you for your answer
I think Neo4j has started, but I can´t reach it through localhost:7474.

what I see on my screen right now is this:
