Many occasions we have been requested to implement help for centralized database (DB) and file storage. Which is comprehensible as a result of these two options open up many handy hosting-building eventualities that have been beforehand unavailable or could possibly be created solely at your individual danger. And likewise as a result of the less single factors of failure (SPOF) you’ve gotten, the extra resistant you’re to faulting the answer. Nevertheless, because the launch of Plesk Obsidian 18.0.49, utilizing centralized DB (as Beta) and Community File System (NFS) has turn out to be potential. Let’s discover out what you are able to do with every of those options.
Beforehand, it was a requirement to have a regionally working database as a result of Plesk makes use of it for storing its personal database (known as “psa”). Even in the event you join an exterior database for the shoppers’ web sites, you need to have an area database service for Plesk. Which means it’s important to preserve that database like set up safety updates, make backups, watch logs, enhance disk and different assets to the server if required, and so forth. And when you’ve got numerous Plesk servers, it generates numerous extra work. This imposes one other severe limitation: you possibly can solely use the database that may be put in on the working system you’re utilizing.
However what has modified since Plesk Obsidian 18.0.49? Let’s dive a bit deeper to seek out out a couple of new eventualities:
There’s additionally a couple of cons:
Let’s begin. It’s not potential to transform an present Plesk set up to Plesk with a distant ‘psa’ database; it ought to be for brand spanking new Plesk installations solely. I made a decision to make use of Oracle Cloud due to ARM servers and their enticing circumstances of free tier for these servers.
First, I create a personal community (“native”, 10.0.0.0/24) in order that the visitors between Plesk and the database server goes inside this community. To make community setup simpler, I enable all visitors contained in the personal community. As you possibly can see within the picture beneath, I even have a community with public entry (“web”).
