OCIで簡単な環境を作ってみた(その2)

Last updated at Posted at 2024-04-23

下記の続きです

OCIで簡単な環境を作ってみた(その1)
https://qiita.com/Cache-Hit/items/994a0095e8965912e677

下記の構成を作成します。
Public SubnetにあるVPNサーバと連携までは前回記事で用意が完了しています。
※疎通用にServerだけは適当に作って起動はしていますが、新たに作成し直します。

ga検証環境.drawio.png

今回作成する内容

  • Serverの作成
  • Apacheの設定とWordpressのインストール
  • Base Databaseの作成
  • データベース作成
  • Wordpressの連携と接続確認

最終的にBase Databaseを用いたWordpressをローカルIPで接続をすることで
VPN経由で作成することができたとします。

今回Serverを設定するにあたり、アウトバウンドの通信が取れないので、
一時的にNAT GATEWAYを作成してアタッチする。

NAT GATEWAY作成

あらかじめNAT GATEWAYという名前で作成しておく。

Private SubnetAのルート・ルールに一時的に追加する。

ルート・ルール
宛先 ターゲットタイプ ターゲット ルート・タイプ
0.0.0.0/0 NATゲートウェイ NAT GATEWAY 静的

Server作成

VPNサーバと同じOSでインスタンスを起動する。

スペックは今回は適当にVM.Standard3.FlexでCPU 2 メモリ15GB にする。
ブートボリュームは最低サイズの50GBで作っておく。

作成後、ローカルIPは10.0.1.18になったので、接続確認をします。

  • ping
C:\Users\81803>ping 10.0.1.18

10.0.1.18 に ping を送信しています 32 バイトのデータ:
10.0.1.18 からの応答: バイト数 =32 時間 =16ms TTL=63
10.0.1.18 からの応答: バイト数 =32 時間 =13ms TTL=63
10.0.1.18 からの応答: バイト数 =32 時間 =13ms TTL=63
10.0.1.18 からの応答: バイト数 =32 時間 =12ms TTL=63

10.0.1.18 の ping 統計:
    パケット数: 送信 = 4、受信 = 4、損失 = 0 (0% の損失)、
ラウンド トリップの概算時間 (ミリ秒):
    最小 = 12ms、最大 = 16ms、平均 = 13ms

  • SELINUX

firewalld停止と自動起動無効化
[root@server ~]# systemctl stop firewalld
[root@server ~]# systemctl disable firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
dnf updateとreboot
[root@server ~]# dnf update -y

[root@server ~]# reboot
必要な最低限をインストール
[root@server ~]# dnf install curl net-tools sysstat bind-utils yum-utils dstat wget rpm-build make git lsof telnet unzip
Apacheのインストール
[root@server ~]# dnf install httpd httpd-devel mailx
自動起動
[root@server ~]# systemctl enable httpd
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.

今回はローカル内のみかつHTTPのみで接続するため、
適当にバーチャルホストを設定します。

ディレクトリ作成
[root@server ~]# mkdir -p /var/www/vhosts/example.domain.com/public_html
[root@server ~]# echo example.domain.com > /var/www/vhosts/example.domain.com/public_html/index.html
