Installing Kibana 4 on CentOS 7

Prerequisites

• Nginx already installed

Environment

• CentOS Linux release 7.0.1406 (Core)
• Nginx 1.9.3
• Kibana 4.1.1

Installing Kibana

$ cd /usr/local/src
$ sudo wget https://download.elastic.co/kibana/kibana/kibana-4.1.1-linux-x64.tar.gz
$ sudo tar xvzf kibana-4.1.1-linux-x64.tar.gz

Editing the Kibana Configuration File

$ vi /usr/local/src/kibana-4.1.1-linux-x64/config/kibana.yml

• Specifying the host

By default it is set to 0.0.0.0.
This time we build it on the same server, so we set it to localhost and save.

- host: "0.0.0.0"
+ host: "localhost"

With this setting, Kibana becomes accessible at localhost.

Creating the Kibana Runtime Path

$ sudo mkdir -p /opt/kibana
$ sudo cp -R /usr/local/src/kibana-4.1.1-linux-x64/* /opt/kibana/

With the above setup, you can run Kibana with the following command.

/opt/kibana/bin/kibana

The above is good enough, but Kibana stops when the machine is rebooted.
So we create a startup script and register it as a service.

Creating the Startup Script

$ sudo vi /etc/systemd/system/kibana4.service

• kibana4.service

[Service]
ExecStart=/opt/kibana/bin/kibana
Restart=always
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=kibana4
User=root
Group=root
Environment=NODE_ENV=production

[Install]
WantedBy=multi-user.target

Save the above.

Starting / Registering the Service

$ sudo systemctl start kibana4
$ sudo systemctl enable kibana4

Installing Nginx

Please refer to the following.

Editing the Nginx Configuration File

Use a reverse proxy to forward to the Kibana 4 port (5601).

$ sudo vi /etc/nginx/conf.d/default.conf

server {
    listen       80;
    server_name  ec2-xx-xx-xxx-xxx.ap-northeast-1.compute.amazonaws.com;

    auth_basic "Restricted Access";
    auth_basic_user_file /etc/nginx/htpasswd.users;

    location / {
        proxy_pass http://localhost:5601;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

}

After saving the configuration above, restart Nginx.

$ sudo systemctl restart nginx

Accessing and Verifying

If it displays as shown below, everything is working fine.

That’s all.
