ネットワーク上にあるServerやネットワーク機器の死活監視などを行うため、Zabbixという統合監視ソフトウェアが人気のようです。
Zabbixでは、次の監視が可能になるとのことです。
- 稼動監視
- リソース監視
- アプリケーション監視
私もセットアップしたいと思い、とりあえず、vagrant環境のCentOS7へインストールしてみました！
セットアップ手順
1. Vangrant構築
> vagrant box add centOS71min https://github.com/holms/vagrant-centos7-box/releases/download/7.1.1503.001/CentOS-7.1.1503-x86_64-netboot.box > mkdir C:\vagrant\hosts\centos71_zabbix24 > cd C:\vagrant\hosts\centos71_zabbix24 > vagrant init centOS71min A `Vagrantfile` has been placed in this directory. You are now ready to `vagrant up` your first virtual environment! Please read the comments in the Vagrantfile as well as documentation on `vagrantup.com` for more information on using Vagrant.
仮想マシンのIPアドレス設定
- 作成されたVagrantfileを編集します。メモ帳などで開き、1行のコメント行を有効にします。
# using a specific IP. # config.vm.network "private_network", ip: "192.168.33.10" <<< 有効化（#を削除する）
起動

2. Server接続（127.0.0.1）
- Tera Termを使ってSSHログインします。
host: 127.0.0.1 port: 2222 user: vagrant pass: vagrant
3. タイムゾーン設定・確認
# timedatectl set-timezone Asia/Tokyo
# timedatectl
Local time: Sun 2015-06-14 19:51:49 JST
Universal time: Sun 2015-06-14 10:51:49 UTC
RTC time: Sun 2015-06-14 10:51:48
Timezone: Asia/Tokyo (JST, +0900)
NTP enabled: n/a
NTP synchronized: no
RTC in local TZ: no
DST active: n/a
4．各種パッケージのアップデート
# yum -y update
5．SELinuxのdisabled
# vi /etc/selinux/config
- すでに｢SELINUX=disabled｣になっていました。
6. ファイアウォール無効化
# systemctl list-unit-files | grep firewall firewalld.service enabled # systemctl disable firewalld.service rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service' rm '/etc/systemd/system/basic.target.wants/firewalld.service' # systemctl list-unit-files | grep firewall firewalld.service disabled
7. Zabbix SIAのリポジトリ登録

12. ZabbixのWebインターフェース用設定ファイル更新
# vi /etc/httpd/conf.d/zabbix.conf php_value date.timezone Asia/Tokyo
13. 各種デーモン起動
# systemctl start zabbix-server Job for zabbix-server.service failed. See 'systemctl status zabbix-server.service' and 'journalctl -xn' for details.
失敗しました！
こちらのサイトを参考にさせてもらいました。
# rpm -Uvh https://kojipkgs.fedoraproject.org/packages/trousers/0.3.11.2/3.fc20/x86_64/trousers-0.3.11.2-3.fc20.x86_64.rpm Retrieving https://kojipkgs.fedoraproject.org/packages/trousers/0.3.11.2/3.fc20/x86_64/trousers-0.3.11.2-3.fc20.x86_64.rpm Preparing... ################################# [100%] Updating / installing... 1:trousers-0.3.11.2-3.fc20 ################################# [ 50%] Cleaning up / removing... 2:trousers-0.3.11.2-3.el7 ################################# [100%] # systemctl restart zabbix-server

14. Webコンソールへアクセス
- Version2.4の導入前に、2.2を入れたためにキャッシュが残っていたので、画面は「Welcome to Zabbix 2.2」となっていますｗ
これでセットアップは完了です！
http://192.168.33.10/zabbix/ へアクセスできるようになりました！！！
