安裝nginx mariadb php

apt update

apt install php-mbstring php-cli php-common php-curl php-fpm php-gd php-mbstring php-mysql php-opcache php-readline php-snmp php-xml php-zip acl curl fping git graphviz imagemagick mariadb-client mariadb-server mtr-tiny nginx-full nmap rrdtool snmp snmpd whois unzip python3-pymysql python3-dotenv python3-redis python3-setuptools python3-systemd python3-pip -y

安裝 Composer

cd /usr/local/bin

curl -sS https://getcomposer.org/installer | php 

mv composer.phar composer 

新增使用者

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

下載LibreNMS

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

設定權限

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/

安裝 LibreNMS和套件

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

exit
pip3 install --user --break-system-packages -r /opt/librenms/requirements.txt

修改PHP時區

sed -i "s|^;date.timezone =.*$|date.timezone = Asia/Taipei|" /etc/php/8.2/fpm/php.ini
sed -i "s|^;date.timezone =.*$|date.timezone = Asia/Taipei|" /etc/php/8.2/cli/php.ini

系統設定時區
timedatectl set-timezone Asia/Taipei

設定 PHP-FPM

cp /etc/php/8.2/fpm/pool.d/www.conf /etc/php/8.2/fpm/pool.d/librenms.conf
nano /etc/php/8.2/fpm/pool.d/librenms.conf

Change [www] to [librenms]:
[librenms]
Change user and group to “librenms”:
user = librenms
group = librenms
Change listen to a unique name:
listen = /run/php-fpm-librenms.sock

systemctl enable php8.2-fpm
systemctl restart php8.2-fpm

設定MariaDB

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

[mysqld]底下新增

innodb_file_per_table=1
lower_case_table_names=0

systemctl enable mariadb
systemctl restart mariadb

MariaDB新增使用者

mysql -u root

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

設定Nginx

建立/etc/nginx/conf.d/librenms.conf

server {
    listen 80;
    server_name librenms.example.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_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_pass unix:/run/php-fpm-librenms.sock;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        include fastcgi_params;
    }
    location ~ /\.(?!well-known).* {
        deny all;
    }
}

rm /etc/nginx/sites-enabled/default
rm /etc/nginx/sites-available/default

systemctl enable nginx
systemctl restart nginx

Enable lnms command completion

ln -s /opt/librenms/lnms /usr/bin/lnms
cp /opt/librenms/misc/lnms-completion.bash /etc/bash_completion.d/

Configure snmpd

cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.conf

curl -o /usr/bin/distro https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/distro
chmod +x /usr/bin/distro
systemctl enable snmpd
systemctl restart snmpd

設定排成

cp /opt/librenms/dist/librenms.cron /etc/cron.d/librenms

啟用調度程式

cp /opt/librenms/dist/librenms-scheduler.service /opt/librenms/dist/librenms-scheduler.timer /etc/systemd/system/

systemctl enable librenms-scheduler.timer
systemctl start librenms-scheduler.timer

Copy logrotate config

cp /opt/librenms/misc/librenms.logrotate /etc/logrotate.d/librenms

瀏覽器http://ip，依序安裝後進行組態驗證

cd /opt/librenms

su librenms

./validate.php

更新PHP8.5

Debian 12官方套件只有到PHP8.2，加入第三方 PPA 來源來升級PHP

apt update

apt-get -y install lsb-release ca-certificates curl apt-transport-https

curl -sSLo /tmp/debsuryorg-archive-keyring.deb https://packages.sury.org/debsuryorg-archive-keyring.deb

dpkg -i /tmp/debsuryorg-archive-keyring.deb

sh -c 'echo "deb [signed-by=/usr/share/keyrings/deb.sury.org-php.gpg] https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'

apt update

自動查詢PHP 8.2套件並安裝對應的 PHP 8.5 套件，php8.5-opcache 已經被直接內建在 php8.5-common 核心套件中故排除即可

apt install -y $(dpkg -l | grep php8.2- | grep -v 'opcache' | awk '{print $2}' | sed 's/php8.2/php8.5/g')

切換系統預設 CLI 版本到 8.5，輸入8.5對應編號1

update-alternatives --config php

root@librenms:~# update-alternatives --config php
There is 1 choice for the alternative php (providing /usr/bin/php).

  Selection    Path             Priority   Status
------------------------------------------------------------
  0            /usr/bin/php8.5   85        auto mode
* 1            /usr/bin/php8.5   85        manual mode

確認版本

root@librenms:~# php -v

sed -i "s|^;date.timezone =.*$|date.timezone = Asia/Taipei|" /etc/php/8.5/cli/php.ini

系統設定時區
timedatectl set-timezone Asia/Taipei

修改PHP-FPM

cp /etc/php/8.5/fpm/pool.d/www.conf /etc/php/8.5/fpm/pool.d/librenms.conf
nano /etc/php/8.5/fpm/pool.d/librenms.conf

Change [www] to [librenms]:
[librenms]
Change user and group to “librenms”:
user = librenms
group = librenms
Change listen to a unique name:
listen = /run/php-fpm-librenms.sock

systemctl enable php8.5-fpm
systemctl restart php8.5-fpm

systemctl restart nginx

確認PHP為8.5

完整移除舊版本

apt purge php8.2 php8.2-*

apt autoremove --purge
