FreeBSD に Zabbix agent をインストールしようと思った経緯
自作の Web アプリを作成しようと思い、実環境にあわせた検証環境を作成しました。
その検証環境が FreeBSD の 12 だったのですが、アプリの稼働確認などで Zabbix で監視できていたら便利かなと思い監視設定を行ってみました。
環境
- OS
- FreeBSD 12.3-RELEASE
root@freebsd12:~ # uname -a FreeBSD freebsd12 12.3-RELEASE FreeBSD 12.3-RELEASE r371126 GENERIC amd64 root@freebsd12:~ #
事前準備
システムのアップデート
コマンド
pkg update pkg upgrade
Zabbix agent のインストール
Zabbix agent モジュールの確認
コマンド
pkg search zabbix | grep agent
実行結果
root@freebsd12:~ # pkg search zabbix | grep agent zabbix4-agent-4.0.30 Enterprise-class open source distributed monitoring (agent) LTS zabbix5-agent-5.0.28 Enterprise-class open source distributed monitoring (agent) LTS zabbix6-agent-6.0.9 Enterprise-class open source distributed monitoring (agent) zabbix62-agent-6.2.3 Enterprise-class open source distributed monitoring (agent) root@freebsd12:~ #
Zabbix サーバーのバージョンが 5.0.x なので、zabbix5-agent-5.0.28 をインストールします。
インストール
コマンド
pkg install zabbix5-agent-5.0.28
実行結果
root@freebsd12:~ # pkg install zabbix5-agent-5.0.28

Message from ca_root_nss-3.83:

FreeBSD does not, and can not warrant that the certification authorities
whose certificates are included in this package have in any way been
audited for trustworthiness or RFC 3647 compliance.
Assessment and verification of trust is the complete responsibility of the
system administrator.
This package installs symlinks to support root certificates discovery by
default for software that uses OpenSSL.
This enables SSL Certificate Verification by client software without manual
intervention.
If you prefer to do this manually, replace the following symlinks with
either an empty file or your site-local certificate bundle.

/usr/local/etc/zabbix5/zabbix_agentd.conf を修正
変更するのは以下の個所。
それぞれの環境にあわせた設定値にしましょう。
Server=127.0.0.1 ServerActive=127.0.0.1 Hostname=Zabbix server
Zabbix agent の起動
コマンド
(起動チェックまで)
echo 'zabbix_agentd_enable="yes"' >> /etc/rc.conf service zabbix_agentd start service zabbix_agentd status
FreeBSD12 には systemctl コマンドは存在しなかった。
ので、service コマンドでサービスの起動を実施。
実行結果
root@freebsd12:~ # systemctl status zabbix-agent systemctl: Command not found. root@freebsd12:~ # root@freebsd12:~ # service zabbix_agentd status Cannot 'status' zabbix_agentd. Set zabbix_agentd_enable to YES in /etc/rc.conf or use 'onestatus' instead of 'status'. root@freebsd12:~ # root@freebsd12:~ # root@freebsd12:~ # echo 'zabbix_agentd_enable="yes"' >> /etc/rc.conf root@freebsd12:~ # service zabbix_agentd start root@freebsd12:~ # root@freebsd12:~ # service zabbix_agentd status zabbix_agentd is running as pid 1730. root@freebsd12:~ #
