tamuraです。 SSLとクライアント認証を使うシステムを作ってみたくなったので、認証局を作ります。
サーバ作成
サーバはazureで作りました。
| OS | コア | メモリ |
|---|---|---|
| CentOS7 | 1 | 1.75GB |
[root@il-sus-web-www2 ~]# cat /etc/centos-release
CentOS Linux release 7.0.1406 (Core) こんな感じです。
で、DNSに追加します。
※お名前.comでドメインを設定しています。
これで、www2.il-sus-web.netという名前でアクセスできます。
サーバ設定
opensslを入れます。
yum -y install openssl認証局(CA)作成
