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



  • 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.

    Thank you, i removed the n and the end of "gpgcheck=1"
    Awesome already installed the Elasticsearch



  • When i run the command " sudo systemctl start nginx"

    i got this error
    Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.

    Help please



  • Type sudo systemctl status nginx and tell us what you get.

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



  • 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


  • Once you put the brace in, then type

    sudo systemctl reload nginx
    sudo systemctl start nginx


  • @johnhooks said:

    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



  • @johnhooks said:

    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?

    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.

    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


  • I removed the
    server {
    include /etc/nginx/default.d/*.conf;
    }

    but when i run the command "nginx -t -c /etc/nginx/nginx.conf" it says

    Thanks, nginx: configuration file /etc/nginx/nginx.conf test is successful

    I probably could have just posted mine earlier and saved all of that 😛

    However when i do the "sudo systemctl reload nginx" or sudo systemctl start nginx
    the Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.
    😁

    what's sudo systemctl status nginx show again?

    Are there quotes around the last curly brace?

    Also, you still need the include /etc/nginx/conf.d/*.conf;

    Here's my nginx.conf file, you can use it.

    Do you have anything else running on port 80?

    What do you get if you type netstat -tulpn?
