CentOS8にNginxとPHP7.3でNextcloudをインストールする方法

Nextcloudソースコードをダウンロードした後、Nextcloud用にNginx仮想ホストをセットアップします。

'/etc/nginx/conf.d'ディレクトリに移動し、新しい構成'nextcloud.conf'を作成します。

cd /etc/nginx/conf.d/
vim nextcloud.conf

次に、ドメイン名とSSL証明書パスを独自のものに変更し、次の構成を貼り付けます。

upstream php-handler {
 #server 127.0.0.1:9000;
 server unix:/run/php-fpm/www.sock;
}

server {
 listen 80;
 listen [::]:80;
 server_name cloud.hakase-labs.io;
 # enforce https
 return 301 https://$server_name:443$request_uri;
}

server {
 listen 443 ssl http2;
 listen [::]:443 ssl http2;
 server_name cloud.hakase-labs.io;

 # Use Mozilla's guidelines for SSL/TLS settings

保存して閉じます。

その後、nginx構成をテストし、Nginxサービスを再起動します。そして、エラーがないことを確認してください。

nginx -t
systemctl restart nginx

これで、Nginxサービスがシステムに新しいHTTPSポートを開きます。次のコマンドを使用して、それを確認してください。

netstat -plntu

そして、以下のような結果が得られます。

その結果、NextcloudのNginx仮想ホスト構成を追加し、その上で安全なHTTPSを有効にしました。
