Change Snap Packages Update Frequency - Step by Step Process ?

This article covers how to use Snap and how it updates. Snap packages are set to refresh (update) 4 times per day by default. 

It should also be noted that automatic updating of snap packages cannot be completely disabled directly from the snapd settings, as there's no option for this (what's up with that?), so if you want to disable this altogether, you'll have to resort to workarounds like blocking the snap update URL, or setting your Internet connection to metered and them using the refresh.metered option to hold the snap refresh process when a metered connection is detected (sudo snap set system refresh.metered=hold).

If you want to check if a certain snap is available from the snap store, use the syntax:

$ snap find [ package name ]

To view the current snap refresh (update) schedule for your system, use:

# snap refresh --time

To change the snap refresh schedule, use:

# sudo snap set system refresh.timer=<frequency>

You'll need to replace <frequency> with the snap refresh frequency you want to set for the timer, as defined in the Snapcraft documentation.

Install CouchDB on CentOS 8 - Step by Step Process ?

This article covers CouchDB installation on CentOS Linux System. 

Apache CouchDB is an open-source database management system, developed by Apache Software Foundation. It is a NoSQL document-store database developed in ErLang.

CouchDB uses multiple formats and protocols to store, transfer, and process its data, it uses JSON (JavaScript Object Notation) to store data, JavaScript as its query language using MapReduce, and HTTP for an API.

Unlike a relational database, a CouchDB database does not store data and relationships in tables. Instead, each database is a collection of independent documents. Each document maintains its own data and self-contained schema.

CouchDB software includes a native web interface i.e. Fauxton for administration of CouchDB database server.

To Install CouchDB Yum Repository on CentOS 8:

1. Create a repo file by using vim editor.

# vi /etc/yum.repos.d/bintray-apache-couchdb-rpm.repo

2. And add following directives in this file.

[bintray--apache-couchdb-rpm]
name=bintray--apache-couchdb-rpm
baseurl=http://apache.bintray.com/couchdb-rpm/el$releasever/$basearch/
gpgcheck=0
repo_gpgcheck=0
enabled=1

3. Build cache for newly installed yum repositories.

# dnf makecache

4. Now we can install CouchDB software by using dnf command.

# dnf install -y couchdb
