  This script installs the community edition of the Seafile Server on a Centos 7 64bit
  - Newest Seafile server version, MariaDB, Memcached, NGINX -
  -----------------------------------------------------------------

  This installer is meant to run on a freshly installed machine
  only. If you run it on a production server things can and
  probably will go terrible wrong and you will loose valuable
  data!

  For questions or suggestions please contact us at
  support@seafile.com

  1 = Seafile Community (Free) Edition (CE)

  Your Seafile server is installed

  Seafile Admin:       ${SEAFILE_ADMIN}
  Admin Password:      ${SEAFILE_ADMIN_PW}

  Seafile DB Credentials:  Check /opt/seafile.my.cnf
  Root DB Credentials:     Check /root/.my.cnf

  This report is also saved to ${TOPDIR}/aio_seafile-server.log



  Next you should manually complete the following steps
  -----------------------------------------------------------------

  1) Log in to Seafile and configure your server domain via the system
     admin area if applicable.

  2) If this server is behind a firewall, you need to ensure that
     tcp port 80 is open.

  3) Seahub tries to send emails via the local server. Install and
     configure Postfix for this to work or
     check https://cloud.seafile.com/published/seafile-manual-cn/config/sending_email.md
     for instructions on how to use an existing email account via SMTP.




  Optional steps
  -----------------------------------------------------------------

  1) Check seahub_settings.py and customize it to fit your needs. Consult
     https://cloud.seafile.com/published/seafile-manual-cn/config/seahub_settings_py.md 
     for possible switches.

  2) Setup NGINX with official SSL certificate.

  3) Secure server with iptables based firewall. For instance: UFW or shorewall

  4) Harden system with port knocking, fail2ban, etc.

  5) Enable unattended installation of security updates. Check
     https://wiki.Ubuntu.org/UnattendedUpgrades for details.

  6) Implement a backup routine for your Seafile server.

  7) Update NGINX worker processes to reflect the number of CPU cores.
