Persiapan

Siapkan sebuah server Linux yang sudah di install. Disini kami menggunakan OS Ubuntu 22.04. LibreNMS ini Support untuk beberapa OS seperti Ubuntu 22.04, Ubuntu 20.04, Centos 8, Debian 11.

Langkah — Langkah

Pertama, rekomendasi dari kami harap Anda untuk melakukan Update pada System Linux terlebih dahulu, agar semua paket yang akan di install juga terbaru/latest. Untuk update System gunakan perintah berikut ini

apt update && apt upgrade

Setelah proses update selesai, Install beberapa depedencies yang diperlukan untuk instal LibreNMS Ubuntu 22.04, Gunakan perintah berikut ini

apt-get install rrdtool whois fping imagemagick graphviz mtr-tiny nmap python3-mysqldb snmp snmpd python3-pip python3-memcache mtr-tiny acl unzip git curl wget -y

Install WebServer, PHP and Database

Selanjutnya untuk kebutuhan LibreNMS, Anda perlu menginstall Nginx Server, Php, and Database, yaitu MariaDB. Ikuti proses Install dengan menggunakan perintah berikut ini

apt-get install nginx mariadb-server php php-pear php-cgi php-common php-curl php-mbstring php-gd php-mysql php-bcmath php-imap php-json php-xml php-snmp php-fpm php-zip -y

Jika proses Installasi sudah selesai, Anda harus mengganti Timezone lokasi dimana Anda berada, agar untuk Log Devide nantinnya sesuai dengan waktu dimana Anda berada.

Untuk mengganti TimeZone cukup dengan mengganti pada file php.ini.

nano /etc/php/8.1/fpm/php.ini
nano /etc/php/8.1/cli/php.ini

Ganti seperti berikut, jika menggunakan Editor nano, dapat menggunakan CTRL + W untuk mencari timezone, lalu ganti seperti berikut

date.timezone = "Asia/Jakarta"

Save and Clode, lalu restart service PHP-FPM yang barusan kita ganti timezone nya

systemctl restart php8.1-fpm

Lalu ganti Timezone server dengan menggunakan perintah berikut ini

timedatectl set-timezone Asia/Jakarta

Create Database Install LibreNMS Ubuntu

Jika Installasi PHP dan Konfigurasinya sudah selesai, selanjutnya kita perlu menambahkan Database untuk LibreNMS. Ikutin perintah berikut ini

Pertama, kita perlu masuk ke Database MariaDB, dengan menggunakan perintah berikut ini

mysql

Buat Sebuah User, Password dan Database. Mengunakan Perintah berikut ini

CREATE DATABASE librenms CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'localhost';
FLUSH PRIVILEGES;

Untuk memastikan Database sudah dibuat, gunakan perintah berikut

show databases;

OUTPUT

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| librenms           |
+--------------------+
2 rows in set (0.002 sec)

Lalu Exit

exit;

Lalu edit konfigurasi Database MariaDB Install LibreNMS Ubuntu. Buka file berikut

nano /etc/mysql/mariadb.conf.d/50-server.cnf

Tambahkan konfigurasi berikut pada diantara line [mysqld] :

innodb_file_per_table=1
sql-mode=""
lower_case_table_names=0

OUTPUT

# this is read by the standalone daemon and embedded servers
[server]
# this is only for the mysqld standalone daemon
[mysqld]
innodb_file_per_table=1
sql-mode=""
lower_case_table_names=0

Simpan dan Close file tersebut, untuk menyetujui perubahan, Restart Service MariaDB

systemctl restart mariadb

Install LibreNMS Ubuntu and Configuration

Pertama untuk mulai Install LibreNMS ubuntu, kita perlu menambahkan user untuk LibreNMS.

useradd librenms -d /opt/librenms -M -r -s "$(which bash)"

Lalu tambahkan user librenms tersebut ke Group www-data. ikuti perintah berikut ini

lalu pindah ke Directory /opt, dan download Package LibreNMS yang terbaru

cd /opt
git clone https://github.com/librenms/librenms.git

SET PERMISSIONS user yang telah kita buat tadi

chown -R librenms:librenms /opt/librenms
chmod 771 /opt/librenms
setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
setfacl -R -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/

Lalu install dependecies

su - librenms
./scripts/composer_wrapper.php install --no-dev

OUTPUT

> LibreNMS\ComposerHelper::preInstall

  - Downloading symfony/polyfill-mbstring (v1.27.0)

Lalu exit dari user librenms

exit

Konfigurasikan PHP-FPM Install LibreNMS

Selanjutnya kita akan mengkonfigurasi PHP-FPM yaitu mengganti user untuk PHP ke librenms. ikut perintah berikut ini

cp /etc/php/8.1/fpm/pool.d/www.conf /etc/php/8.1/fpm/pool.d/librenms.conf
nano /etc/php/8.1/fpm/pool.d/librenms.conf

Ganti [www] to [librenms]

[librenms]

dan juga untuk user dan group ganti juga ke librenms

user = librenms
group = librenms

pada bagian listen pastikan sesuai dengan konfigurasi web server kita
(fastcgi_pass untuk NGINX) dan SetHandler untuk APACHE

listen = /run/php-fpm-librenms.sock

Konfigurasi Web Server (Install LibreNMS Ubuntu)

Selanjutnya kita akan mengkonfigurasi We Server NGINX, agar dapat diakase menggunakan Browser. masuk ke file config librenms

nano  /etc/nginx/conf.d/librenms.conf

Tambahkan script berikut ini, untuk server_name dapat disesuikan dengna Domain atau IP Address yang Anda gunakan

server {
 listen      80;
 server_name librenms.dixmata.com;
 root        /opt/librenms/html;
 index       index.php;
 charset utf-8;
 gzip on;
 gzip_types text/css application/javascript text/javascript application/x-javascript image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;
 location / {
  try_files $uri $uri/ /index.php?$query_string;
 }
 location ~ [^/]\.php(/|$) {
  fastcgi_pass unix:/run/php-fpm-librenms.sock;
  fastcgi_split_path_info ^(.+\.php)(/.+)$;
  include fastcgi.conf;
 }
 location ~ /\.(?!well-known).* {
  deny all;
 }

Hapus file config default dari Nginx agar tidak bentrok dengan konfigurasi LibreNMS yang akan kita buat.

rm /etc/nginx/sites-enabled/default

Save and Close, Uji coba konfigurasi Nginx yang telah kita tambahkan, apakah terjadi error. Gunakan perintah berikut ini.

nginx -t

OUTPUT

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Jika OK, maka lakukan Restart pada Service NGINX Web Server.

systemctl restart nginx

Check Status nginx, dengan perintah berikut ini

systemctl status nginx

OUTPUT
