Graylog

I tried to install Graylog using the steps below, but it didn't work, I got the following message:

$ wget https://packages.graylog2.org/repo/packages/graylog-4.1-repository_latest.deb
$ sudo dpkg -i graylog-4.1-repository_latest.deb
$ sudo apt-get update && sudo apt-get install graylog-server graylog-enterprise-plugins graylog-integrations-plugins graylog-enterprise-integrations-plugins

ubuntu@ubuntu:~$ sudo apt-get install graylog-server

ubuntu@ubuntu:~$

Therefore, I followed the Manual Setup

Downloaded the server from here:

ubuntu@ubuntu:~$ wget https://downloads.graylog.org/releases/graylog/graylog-4.1.3.tgz

Uncompressed and extracted the installation files:

ubuntu@ubuntu:~$ tar xfz graylog-4.1.3.tgz
ubuntu@ubuntu:~$ ls -lrt
total 192540
-rw-rw-r-- 1 ubuntu ubuntu      1768 May 15  2018 myKey

drwxrwxr-x 5 ubuntu ubuntu      4096 Aug 31 10:51 graylog-4.1.3

Renamed the folder:

ubuntu@ubuntu:~$ mv graylog-4.1.3 graylog
ubuntu@ubuntu:~$ cd graylog/
ubuntu@ubuntu:~/graylog$ ls -lrt

drwxrwxr-x 2 ubuntu ubuntu      4096 Aug 31 10:51 bin

Created the required folders:

ubuntu@ubuntu:~/graylog$ sudo mkdir /etc/graylog/
ubuntu@ubuntu:~/graylog$ sudo mkdir /etc/graylog/server/

Created the sha password:

ubuntu@graylog:~$ echo -n "Enter Password: " && head -1 </dev/stdin | tr -d '\n' | sha256sum | cut -d" " -f1
Enter Password: Str0ngPassw-rdH3re
7b5600e954f7206c67a31c02b532254c483966d1b2dcd9b3331eda95c93a5c68

Copied the config file to /etc/graylog/server

ubuntu@graylog:~$ sudo cp graylog.conf.example /etc/graylog/server/server.conf

Edited the config file adding the password and password sha:

ubuntu@graylog:~$ sudo vi /etc/graylog/server/server.conf

password_secret = Str0ngPassw-rdH3re

root_password_sha2 = 7b5600e954f7206c67a31c02b532254c483966d1b2dcd9b3331eda95c93a5c68

Installed Java
