実行環境

Raspberry Pi 4 Model B (8GB)
Raspberry Pi OS (Bookworm)

導入手順

基本は以下の URL に従って導入する
- https://www.zabbix.com/download?zabbix=7.0&os_distribution=raspberry_pi_os&os_version=12&components=server_frontend_agent&db=pgsql&ws=nginx
MySQL 導入は面倒そうだったので PostgreSQL を選択

1 Choose your platform

Key	Value
ZABBIX VERSION	7.0 LTS
OS DISTRIBUTION	Raspberry Pi OS
OS VERSION	12 (Bookworm)
ZABBIX COMPONENT	Server, Fontend, Agent
DATABASE	PostgreSQL
WEB SERVER	Nginx

2 Install and configure Zabbix for your platform

a. Install Zabbix repository

wget https://repo.zabbix.com/zabbix/7.0/raspbian/pool/main/z/zabbix-release/zabbix-release_latest_7.0+debian12_all.deb
sudo dpkg -i zabbix-release_latest_7.0+debian12_all.deb
rm zabbix-release_latest_7.0+debian12_all.deb
sudo apt update

b. Install Zabbix server, frontend, agent

sudo apt install -y zabbix-server-pgsql zabbix-frontend-php php8.2-pgsql zabbix-nginx-conf zabbix-sql-scripts zabbix-agent

別で PostgreSQL の導入も必要だったので Install

sudo apt install -y postgresql postgresql-server-dev-all

c. Create initial database

non-interactive で操作する

POSTGRES_USER="zabbix"
POSTGRES_PASSWORD="zabbix"
#sudo -u postgres createuser --pwprompt "${POSTGRES_USER}"
sudo -u postgres psql -c "create role ${POSTGRES_USER} with login password '${POSTGRES_PASSWORD}';"
sudo -u postgres createdb -O ${POSTGRES_USER} zabbix 
zcat /usr/share/zabbix-sql-scripts/postgresql/server.sql.gz | sudo -u zabbix psql zabbix

d. Configure the database for Zabbix server

sudo sed -i.bak -e "s/# DBPassword=/DBPassword=${POSTGRES_PASSWORD}/" /etc/zabbix/zabbix_server.conf

e. Configure PHP for Zabbix frontend

(ここの項目名 PHP じゃなくて Nginx じゃない？)
80 番ポートで待ち受けるようにする

sudo sed -i.bak -i "2i listen 80;" /etc/zabbix/nginx.conf
sudo sed -i.ba2k -i "3i server_name <your domain>;" /etc/zabbix/nginx.conf

Zabbix 公式サイトの手順から抜けている Nginx の設定を行う
- 初期設定のままだと、Nginx と Zabbix Nginx の設定が衝突して Nginx 側の設定が優先されてしまう

z. raspi の初期設定だといくつかエラーが出るのでその設定を行う

# Locale (en_US) 導入
sudo raspi-config nonint do_change_locale en_US.UTF-8

f. Start Zabbix server and agent processes

sudo systemctl restart zabbix-server zabbix-agent nginx php8.2-fpm
sudo systemctl enable zabbix-server zabbix-agent nginx php8.2-fpm

g. Open Zabbix UI web page

Zabbix が走っているサーバの http://***.***.***.***/ でアクセス
- ユーザ名：Admin、パスワード：zabbix
Pre-Check で Locale のエラーが出る場合は、適切 Locale が Install されていない
Zabbix UI ではなく Nginx の Welcome page が表示される場合、Nginx 側の設定が無効化できていない
