Cassandra multinode installation,Cannot open file /var/log/cassandra/gc.log due to Permission denied

Question

I want to install Cassandra on 4 remote nodes. Everything works fine until I come to point when I check status

nodetool status
Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address    Load       Tokens       Owns (effective)  Host ID                               Rack
UN  127.0.0.1  103.68 KiB  256          100.0%            4e03d80f-5972-4bc7-b36d-6e536ebfa808  rack1

I have properly set listen_address to 192.68.0.25 and seeds to 192.69.0.13

I got same on the other node

Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address    Load       Tokens       Owns (effective)  Host ID                               Rack
UN  127.0.0.1  103.64 KiB  256          100.0%            c7ad74b0-9fa1-4068-a2f8-24e45523b731  rack1

This is what I got when I run cassandra from command shell

    OpenJDK 64-Bit Server VM warning: Cannot open file /var/log/cassandra/gc.log due to Permission denied

Actually I do not have gc.log.This is the content of the folder

/var/log/cassandra$ ls *.log
debug.log  system.log

And

/var/log$ ls -lia cassandra/
total 284

The error message means you have an invalid yaml file, could upload it to pastebin? — Gabor Vincze, Jan 25 '18 at 17:11
Also check whether the directory can be written by the cassandra user (or whichever you run it from) and when running from command line make sure you run it with sudo, or if you ran it from root, chown the dirs back — Gabor Vincze, Jan 25 '18 at 17:12

Make sure, your /etc/hosts file format is valid, such as

root@my-cass1-1:~# cat /etc/hosts | egrep -v "^#|::"
127.0.0.1 localhost
192.168.xxx.13 my-cass1-1.int.xxxxxxxxx.tld my-cass1-1

And no localhost.localdomain stuff in it.

in cassandra.yaml set these two options:

root@my-cass1-1:~# cat /etc/cassandra/cassandra.yaml | grep 192.168
          - seeds: "192.168.xxx.111,192.168.xxx.112,192.168.xxx.13,192.168.xxx.10"
listen_address: 192.168.xxx.13
broadcast_rpc_address: 192.168.xxx.13
