The initial script (install-nextcloud.sh // install-nextcloud-debian.sh) will install your self hosted Nextcloud within few minutes fully automated. Your server will consist of:

Fail2Ban (Nextcloud and SSH jails)
MariaDB 10.3
Nextcloud 15
NGINX 1.15.8 TLSv.1.3
OpenSSL 1.1.1
PHP 7.2
Redis-Server
self signed or Let's Encrypt SSL using the second script
UFW (22, 80, 443)

The only precondition for the install-nextcloud.sh and install-nextcloud-debian.sh shell script is to utilize Ubuntu 18.04 LTS or Debian Stretch 9.x as your on-prem server OS. Optionally you may request your ssl certificate from Let's Encrypt by issuing the second script called "ssl-certificate.sh".

Beyond that you will find additional scripts at /usr/local/src/install-nextcloud/

fail2ban.sh
optimize.sh
restart.sh
ssl-renewal.sh
upgrade.sh

to optimize and maintain your Ubuntu system easily.
