How To Install Elasticsearch, Logstash, and Kibana 4 on CentOS 7

Joy

Hi ML People,
I'm doing some Linux Project-Just for practice only.
Now I'm following this guide
https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-4-on-centos-7
However I this this part"
sudo rpm --import http://packages.elasticsearch.org/GPG-KEY-elasticsearch

**Create and edit a new yum repository file for Elasticsearch:
**
sudo vi /etc/yum.repos.d/elasticsearch.repo

Add the following repository configuration:
/etc/yum.repos.d/elasticsearch.repo

[elasticsearch-1.4]
name=Elasticsearch repository for 1.4.x packages
baseurl=http://packages.elasticsearch.org/elasticsearch/1.4/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1

I can't move due to error "Repository 'elasticsearch-1.4': Error parsing config: Error parsing "gpgcheck = '1\ng'": invalid boolean value
"

Looks like you have a \ng in your text file. Open up the file in question, look for the like that should end in =1 but actually ends in =1\ng and remove the \ng.

Can you paste the contents your /etc/nginx.conf file?

Looks like you missed the last }. Put one after the curly brace at the bottom of your config file.

stacksofplates

That's what this line is saying, I just wanted to double check.

Oct 22 05:13:26 localhost.localdomain nginx[11343]: nginx: [emerg] unexpected end of file, expecting "}" in /etc/nginx...nf:41

stacksofplates

Once you put the brace in, then type

sudo systemctl reload nginx
sudo systemctl start nginx

Joy

Once you put the bracket in, then type
sudo systemctl reload nginx
sudo systemctl start nginx

I will double check my config, I'll get back

I already did and i got the same error

Ok what's the ouput of sudo systemctl status nginx again? Does it still say expecting "}" in /etc/nginx.conf:41?

server {
     
    include /etc/nginx/default.d/*.conf;
}

If you made a config file in /etc/nginx/conf.d/ then take out

server {
    include /etc/nginx/default.d/*.conf;
}

Then do

sudo systemctl reload nginx
sudo systemctl restart nginx

I apologize, I should have caught that in the beginning.

Did you create a .conf file in /etc/nginx/conf.d/?

yes, i did. I will check the file and will post it here

Ok. You will want to remove

server {
    include /etc/nginx/default.d/*.conf;
}

from the /etc/nginx/nginx.conf file.

Then type:

sudo systemctl reload nginx
sudo systemctl restart nginx
