Install vnStat 2.1 di Debian 9

Last Updated on 18 March 2019 By tommy Leave a Comment

Bila anda menggunakan vnstat dari repository Debian, vnstat yang digunakan versi jadul 1.15, kadang error yang muncul

$ vnstat
eth0: Not enough data available yet.

Solusi : Compile vnstat dari Source Code

Solusinya adalah mengcompile vnstat dari source code langsung

apt install wget make gcc libsqlite3-dev

Download source code vnstat

wget https://humdi.net/vnstat/vnstat-2.1.tar.gz

Ekstrak dan install

tar zxvf vnstat-2.1.tar.gz
cd vnstat-2.1
./configure --prefix=/usr --sysconfdir=/etc && make && make install

Edit file vnstat.conf

Bila nama interface anda bukan eth0, buka file /etc/vnstat.conf, ubah bagian

Interface "eth0"

menjadi

Interface "ens18"

untuk melihat nama interface yang benar bisa menggunakan perintah ifconfig

Ubah file permission

Ubah file permission di /var/lib/vnstat agar dapat dibaca/tulis oleh user vnstat

chown vnstat:vnstat /var/lib/vnstat -R

Systemd Daemon

Agar vnstat otomatis dijalankan dan merekam aktivitas bandwitdh anda aktifkan service systemd

cp -v examples/systemd/vnstat.service /etc/systemd/system/
systemctl enable vnstat
systemctl start vnstat

tunggu sekitar 1-5 menit untuk proses pengumpulan data pertama lalu cek penggunaan bandwitdh dengan vnstat atau untuk cek traffic live dengan vnstat -l, contoh output di server saya

$ vnstat -m
 
 eth0  /  monthly
 
       month        rx      |     tx      |    total    |   avg. rate

Bash Linux netstat: command not found di Debian/Ubuntu

Last Updated on 12 March 2018 By tommy Leave a Comment

Bila anda mendapati netstat, ifconfig, ipmaddr, route, mii-tool atau arp, ini terjadi karena Debian/Ubuntu sudah menggunakan ip sebagai default untuk melihat info jaringan.

Solusinya adalah menginstall paket net-tools

apt install net-tools -y
# atau 
apt-get install net-tools -y

setelah selesai coba salah satu perintah diatas.

Error diatas terjadi karena paket yang akan anda install tidak bisa diverifikasi oleh apt, makanya muncul error, coba update repository anda

apt-get update

Bila muncul error seperti ini

Ign http://kambing.ui.ac.id jessie InRelease
Hit http://security.debian.org jessie/updates InRelease
Get:1 http://security.debian.org jessie/updates/main Sources [172 kB]
Hit http://kambing.ui.ac.id jessie-updates InRelease                  
E: Release file for http://kambing.ui.ac.id/debian/dists/jessie-updates/InRelease is expired (invalid since 5d 13h 35min 24s). Updates for this repository will not be applied.

Ganti repository dengan default dari Debian, buka file /etc/apt/sources.list ganti isinya dengan

deb http://httpredir.debian.org/debian jessie main
deb-src http://httpredir.debian.org/debian jessie main
 
deb http://httpredir.debian.org/debian jessie-updates main
deb-src http://httpredir.debian.org/debian jessie-updates main
 
deb http://security.debian.org/ jessie/updates main
deb-src http://security.debian.org/ jessie/updates main

Lalu update kembali

apt-get clean all
apt-get update

Install Debian Keyring

apt-get install debian-keyring debian-archive-keyring
apt-get clean all;
apt-get update

masalah teratasi.

Solusi Error PHP nginx Permission denied while connecting to upstream

Last Updated on 5 December 2016 By tommy 1 Comment

Saat menggunakan nginx dan php-fpm error yang sering muncul adalah

2016/12/05 12:01:05 [crit] 20397#20397: *3 connect() to unix:/run/php/php7.0-fpm.pid failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: localhost, request: “GET /info.php HTTP/1.1”, upstream: “fastcgi://unix:/run/php/php7.0-fpm.pid:”, host: “localhost”

Bila anda menggunakan PHP 5 biasanya socketnya berada di /var/run/php5-fpm.sock.

Solusi

Error unix:/run/php/php7.0-fpm.pid failed (13: Permission denied) while connecting to upstream bisa disebabkan oleh salah user/group nginx, php-fpm atau root location di server block (virtualhost) nginx.
Sebagai solusinya kita akan menjalankan nginx sebagai www-data, bisa juga diganti dengan nginx, apache dan lain sebagainya.

1. User Group

Pastikan user/group www-data tersebut sudah ada

$ id www-data
uid=33(www-data) gid=33(www-data) groups=33(www-data)

ganti www-data dengan user yang ingin di cek.

2. User nginx

Buka file /etc/nginx/nginx.conf, ubah bagian

user  nginx;

menjadi

user  www-data;

lalu restart nginx

service nginx restart

3. User php-fpm

PHP 7
buka file /etc/php/7.0/fpm/pool.d/www.conf, sesuaikan dengan nilai dibawah ini

user = www-data
group = www-data
listen = /run/php/php7.0-fpm.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

PHP 5
buka file /etc/php5/fpm/pool.d/www.conf, sesuaikan dengan nilai dibawah ini

user = www-data
group = www-data
listen = /var/run/php5-fpm.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

lalu restart php-fpm

# php 7.0
service php7.0-fpm restart
# php5
service php5-fpm restart

4. Server Block alias Virtualhost

Sesuaikan alamat socket php-fpm, contoh di server block nginx
PHP 7

  location ~ \.php$ {
    try_files $uri =404;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }

PHP 5

  location ~ \.php$ {
    try_files $uri =404;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }

lalu update file cache apt-get

apt-get update; apt-get upgrade -y
