数日前、VPS を購入し、そこに Centos 7 をインストールしました。現在、SSH 用に fail2ban を設定しようとしています。epel-release をインストールしました。デフォルトで Iptables が使用されていました。fail2ban を起動しようとすると、次のメッセージが表示されます。
Job for fail2ban.service failed because the control process exited with error code. See "systemctl status fail2ban.service" and "journalctl -xe" for details.
fail2ban開始のデバッグ:

Iptables を再インストールしようとしましたが、新規インストール後もセキュア ログ ファイルが見つかりません。VPS プロバイダーの設定が原因でしょうか?
答え1
不足しているファイルを作成してみませんか?
touch /var/log/secure
chown root. /var/log/secure
chmod 0600 /var/log/secure
それから:
systemctl restart fail2ban.service
/var/log/secure
は から来ていますrsyslog
。authpriv.* /var/log/secure
が にあり/etc/rsyslog.conf
、rsyslog
実行されていることを確認してください:
systemctl status rsyslog
