VirtualHost の設定（複数バーチャル・ホスト）

小ネタですが、サブドメインなど複数バーチャル・ホストを設定したときのメモ

/etc/httpd/conf.d/vhost.conf 内、下記の記述があるので、ServerName をサブドメイン（もしくは別ドメイン）に変更した <VirtualHost *:80> から </VirtualHost> までを丸ごとコピー＆ペーストして、vhost.conf に追加（オリジナルのドメインの記述はそのまま）：

<VirtualHost *:80>

  # REQUIRED. Set this to the host/domain/subdomain that

  # you want this VirtualHost record to handle.

  ServerName ほげほげ.com

  # Optional. You can specify additional host names that

  # serve up the same site. This can be top-level, domains,

  # sub-domains, and can even use wildcard subdomains such

  # as *.yourdomain.com - just separate each host name

  # with a single space.

  #ServerAlias ほげほげ.com

  # REQUIRED. Set this to the directory you want to use for

  # this vhost site's files.

  DocumentRoot /var/www/html/ほげほげ

  # Optional. Uncomment this and set it to your admin email

  # address, if you have one. If there is a server error,

  # this is the address that Apache will show to users.

  ServerAdmin admin@ほげほげ.com

  # Optional. Uncomment this if you want to specify

  # a different error log file than the default. You will

  # need to create the error file first.

  #ErrorLog /var/www/vhosts/logs/error_log

  # REQUIRED. Let's make sure that .htaccess files work on 

  # this site. Don't forget to change the file path to

  # match your DocumentRoot setting above.

  

  <Directory /var/www/html>

    AllowOverride All

  </Directory>

</VirtualHost>

Apache を再起動して設定を反映：

 sudo systemctl restart httpd 

DocumentRoot は別ディレクトリに作成して、アクセス権を設定（参照）

SSL は追加したドメイン（またはサブドメイン）ごとに新規に証明書を生成しなくてはいけないが（参照）今回はスキップ。
