[root@jumpwjv ~]#
[root@jumpwjv ~]# cd web-vmstats-master/
[root@jumpwjv web-vmstats-master]#

Selanjutnya membuat direktori dan copy data yang ada di web-vmstat-master ke diretori yang Anda buat

[root@jumpwjv web-vmstats-master]# mkdir /opt/web_vmstats
[root@jumpwjv web-vmstats-master]# cp -r web/* /opt/web_vmstats/
[root@jumpwjv web-vmstats-master]# ls /opt/web_vmstats/
index.html js stats.css stats.js
[root@jumpwjv web-vmstats-master]#

Langkah selanjutnya adalah unduh dan install program streaming websocketd. Buka halaman WebSocket resmi dan unduh paket agar sesuai dengan arsitektur sistem Anda (Linux 64-bit, 32-bit atau ARM).

32-bit System

1

# wget https://github.com/joewalnes/websocketd/releases/download/v0.2.9/websocketd-0.2.9-linux_386.zip

64-bit System

1

# wget https://github.com/joewalnes/websocketd/releases/download/v0.2.9/websocketd-0.2.9-linux_amd64.zip

Disini kami menggunakan 64-bit system silakan gunakan wget untuk mengunduhnya seperti berikut

[root@jumpwjv web-vmstats-master]# unzip websocketd-0.2.9-linux_amd64.zip

[root@jumpwjv web-vmstats-master]#
[root@jumpwjv web-vmstats-master]# websocketd --port=8080 --staticdir=/opt/web_vmstats/ /usr/bin/vmstat -n 1
Sun, 15 Nov 2020 01:00:00 +0000 | INFO | server | | Serving using application : /usr/bin/vmstat -n 1
Sun, 15 Nov 2020 01:00:00 +0000 | INFO | server | | Serving static content from : /opt/web_vmstats/
Sun, 15 Nov 2020 01:00:00 +0000 | INFO | server | | Starting WebSocket server : ws://:8080/
Sun, 15 Nov 2020 01:00:00 +0000 | INFO | server | | Serving CGI or static files : http://:8080/

Deskripsi setiap parameter diatas sebagai berikut:

  • –Port = 8080: Port yang digunakan untuk terhubung pada protokol HTTP - Anda dapat menggunakan nomor port yang Anda inginkan.
  • –Staticdir = /opt/web_vmstats/: Jalur tempat semua file web Web-Vmstat dihosting.
  • /usr/bin/vmstat -n 1: Perintah Linux Vmstat yang memperbarui statusnya setiap detik. Terlihat diatas web vmstat sudah running.

Selanjutnya kita akan membuat bash script, script ini sebenarnya hanya opsional dan hanya sistem yang support script init. Untuk mengelola Websocket sebagai daemon sistem, sebagai berikut

[root@jumpwjv web-vmstats-master]#
[root@jumpwjv web-vmstats-master]# vim /etc/init.d/web-vmstats

#!/bin/sh
# source function library
. /etc/rc.d/init.d/functions
start() {
                echo "Starting webvmstats process..."

/usr/bin/websocketd --port=8080 --staticdir=/opt/web_vmstats/ /usr/bin/vmstat -n 1 &
}

stop() {
                echo "Stopping webvmstats process..."
                killall websocketd
}

case "$1" in
    start)
       start
        ;;
    stop)
       stop
        ;;
    *)
        echo "Usage: stop start"
        ;;
esac

Selanjutnya jika sudah silakan berikan hak akses execute ke file web-vmstat yang berada di init.d dan silakan start web-vmstats seperti berikut

[root@jumpwjv web-vmstats-master]#
[root@jumpwjv web-vmstats-master]# chmod +x /etc/init.d/web-vmstats
[root@jumpwjv web-vmstats-master]# /etc/init.d/web-vmstats start
Reloading systemd: [OK]
Starting web-vmstats (via systemctl): [OK]
[root@jumpwjv web-vmstats-master]#

Apabila sudah running, selanjutnya Anda dapat akses IP server Anda beserta port 8080 seperti berikut: http://IP_server:8080

Selamat mencoba 😁
