  17. yum -y install wget
  18. wget '<Download-URL>' -O '<Installer-filename>'
  19. yum -y install perl-Data-Dumper
  20. Create appropriate swap space using CentOS 7.x adding swap space using file

  28. Generate lets-encrypt certificate if public DNS FQDN is set using:
    cd /opt/wordpress-<ver>
    ./bncert-tool --perform_dns_validation 0
    https://docs.bitnami.com/aws/how-to/generate-install-lets-encrypt-ssl/
  29. 'crontab -e' and update

    /opt/wordpress-<ver>/mysql/bin/mysql -u bn_wordpress -p bitnami_wordpress
    with password read in above step
  36. Create /opt/take-database-backup.sh with following contents:
    /opt/wordpress-<ver>/mysql/bin/mysqldump -u bn_wordpress -p<password> bitnami_wordpress | bzip2 > /opt/bitnami_wordpress.sql.bz2
