The Plesk web server is basically Nginx.

You can add
to /etc/sw-cp-server/fastcgi_params.

Don't forget to reload the new configuration.

ICANN policies have been becoming more and more insane.

The only thing you can do is ensure that that correct e-mail contact is being used in the registration.

As in-memory key/value store, for caching mostly. Do understand that it's not secure if you plan on using it on a shared hosting platform.

This is a good thing, and should be painless. However, if any of your php scripts created new files on your old system they will be owned by apache.apache or apache.psacln and will need to be converted to [ftpusrrname].psacln MANUALLY once migrated. (you can also do it automatically using one of th...

A password is a password. If you need stronger authentication, than use something else (or additionally to the password) as authentication. In any MySQL flavour, also MariaDB, you use password() for password hashing, see https://mariadb.com/kb/en/mariadb/password/. Protip: firewall your MySQL server.

If you run Apache 2.4 with MPM Event, you really don't need Nginx, and you can still use an advanced mod_security setup.

"XPath error : Invalid expression" comes from a web application. Since the line is in your Apache error_log, probably from a PHP application under mod_php running an XPath query on XML data.

It is absurd for an MX not to support TLS. This forces all your messages to be shouted in clear text over the internet from server to server. qmail was written before tls even existed. is it any wonder it doesnt support it? of course you could ask for your money back lol I wasn't complaining about ...

Assuming the metrics provided are correct, it seems that the disk was incredibly slow between 9:10 and 9:20. This caused processes waiting on the disk, temporarily slowing down everything. Perhaps a RAID rebuild? Hardware issues? Overbooked public cloud?

Using a single connection will most likely be more efficient. However, if you keep the connection open for a long time, without really using it, you will be wasting a tiny bit of memory and an otherwise available connection slot on the database server. If you have a huge amount of concurrent request...

That entirely depends on your hardware and work load. Unfortunately there is no silver bullet solution. Some people dedicate their entire work to achieving the optimal settings for database servers. You could start at reading the documentation carefully, and read in on stuff like the Percona blog, b...

"COMPACT" is the default row format for InnoDB tables.

But I guess you mean something else? Compression? Although possible when using the Barracuda file format for InnoDB tables, why on earth would you want compression for your databases?

Table-level encryption is possible with MariaDB 10.1. See https://mariadb.com/kb/en/mariadb/data-at-rest-encryption/ If you do not want to use this feature, or if you are (most likely) on an older MySQL/MariaDB version you could use an encrypted file system. (You should probably not forget to encryp...

This is a bug in the package from Atomic.

A package should never manually create files or directories in /run (or /var/run, which is a symlink to /run) on installation. Systemd with tmpfiles is the way to go, see "man tmpfiles.d".
