Installing Drupal

I am attempting to install Drupal 8.4.0 on a client's hosting, which is a GoDaddy Classic Linux account. I launch the installer, and I get the following warnings;
 

Warnings found

PHP OPCODE CACHING Not enabled

PHP OPcode caching can improve your site's performance considerably. It is highly recommended to have OPcacheinstalled on your server.

LIMITED DATE RANGE Your PHP installation has a limited date range.

After many failed trials (php -r, ...) , the sanest way that worked to get Composer running was: 

# curl -s getcomposer.org/installer | php -d detect_unicode=Off -d allow_url_fopen=On
# mv ./composer.phar /usr/local/bin/
# ln -s /usr/local/bin/composer.phar /usr/local/bin/composer
# composer

Hope this saves someone the hours I lost.

FreeBSD - 11.3
drupal8 version 8.4.1
php version 5.6.32 (cli)

When attempting to add content or perform any other function except signing in,I receive this error message:

The website encountered an unexpected error. Please try again later.

This is from the apache24 error log:

FreeBSD-11.3 /64 bit

This is the first time I have tried installing Drupal8. I get as far as enering the database info, and them the setup crashes with this message. I have cleared out everything and retried several times with no lucK. I am about ready to give up. I have no idea what is wrong.

Dear Community!

I am moving a working Drupal 8.4 installation from an ubuntu on raspberry to a centOS 7.3 (root server). On the target system there are other running websites, including a working Drupal 8.4

My problem: after migration, including install of composer, setup of MariaDB 10.2, copying of files (rights checked), I can get the static files, like robots.txt, but I get errors with the drupal pages: »The website encountered an unexpected error. Please try again later.«

I want to install Drupal 8.4.0 onto a shared 1and1 server. I downloaded all the files, prepared the database, set the PHP version to 7.1, but on the very first install screen, before I have done anything, I am getting the following error:

Strict Standards: DateTime::createFromFormat(): We selected 'Europe/Berlin' for 'CEST/2.0/DST' instead in /homepages/0/d309344694/htdocs/drupal8/vendor/symfony/http-foundation/Response.php on line 231
