Install and use collectd under CentOS Stream 9 using OpsTools

collectd is a daemon, which collects system data and statistics and it may send them over the network to a back-end data. Under CentOS Stream 9 the collectd package has been removed from the CentOS Stream 9 repositories. Special Interest Groups (SIG), which is a group of CentOS Community, provides and supports multiple small repositories for different Linux utilities and tools. One of the SIG‘s repositories is OpsTools, which provides a package for collectd daemon and multiple collectd modules packed in separate packages.

To use collectd under CentOS Stream 9 a CentOS Community repository should be installed – OpsTools.

Steps to install and use the collectd daemon:

dnf install -y centos-release-opstools
dnf install -y collectd

It’s worth noting that all the Linux distribution, which tries to track and be compatible with Red Hat Enterprise Linux like Rocky Linux will have the same problem with missing collectd package. So the SIG OpsTools repository should be also possible to install under all of these Linux distributions.

Here is the output of installing the above packages under CentOS Stream 9:

collectd default configuration

The default configuration comments all the lines in /etc/collectd.conf except one, which includes all the files under /etc/collectd.d/. So the logic is to have a separate file for each collectd plugin. By default, there are 5 default configuration files activating 5 plugins:

Software comparison Ubuntu server 22.04 LTS vs CentOS Stream 9 head-to-head

The following article compares two different and very popular for servers Linux distros with Ubuntu Server 22.04 LTS (Jammy) and CentOS Stream 9. These are the latest versions released in the past month. Bear in mind, that they have different release cycle, but the these are the system with log support up to 2032! The two Linux distors Ubuntu Server 22.04 LTS (Jammy) and CentOS Stream 9 support is till 2032! Here is the links to their life cycle and what kind of support could be expected in the time frame of 10 years:

Ubuntu 22.04 LTS life cycle – https://ubuntu.com/about/release-cycle. In simple words – 5 years of Standard and 5 years of Extended/Security support till April 2032.
CentOS Stream 9 life cycle –https://access.redhat.com/support/policy/updates/errata#RHEL9_Planning_Guide. In simple words – 5 years of Full and 5 years of Maintenance support till April 2032.

In the Desktop world upgrading to the new and latest version of a Linux distribution is almost mandatory, but in the server world, upgrading is more complicated. The first step in updating a server is to check what software versions come with the new distribution version and then check whether the running custom (application) software supports the software versions. For example, updating to a new distribution version, which comes with PHP 8.1, but the current application supports only 7.4 is not very wise and in addition, the current version may have years of support in the future.

Lately, with the virtualization and container software and it is more common to choose a long-living Linux distribution for the host and more short-living with bleeding edge technologies for the guest environments. So check out the Fedora 36 Server Edition articles in the site – Minimal network installation of Fedora 36 Server, Software and technical details of Fedora Server 36 including cockpit screenshots and the comparison software table between Ubuntu 22.04 LTS and Fedora 36 Server Edition – Software comparison Ubuntu server 22.04 LTS vs Fedora 36 server edition – head-to-head.

Network installation of CentOS Stream 9 (20220606.0) – minimal server installation

Minimal net install is useful when a dedicated server is installed from a IPMI KVM or Dell iDRAC, HP iLO, IBM IMM or where the initial client side download of files need to be minimal.
CentOS Stream 9 is receives the updates before Red Hat Enterprise Linux (RHEL) and there is no versioning except the major release, which is 9. So the CentOS Stream 9 receives the updates for Red Hat Enterprise Linux (RHEL) 9. On monthly or less basis CentOS community releases a stable ISO with a temporary time version like this one CentOS Stream 9 (20220606.0).

Building python 3.10.4 and possibly undefined macro: AC_MSG_ERROR

Emerging the new python 3.10 in Gentoo may lead to the following error, despite all the dependencies installed. This error might also occur in any other Linux distro! During the configure stage the autoconf tool outputs error:

Migrate emails from GMail to another IMAP server with imapsync

It appears pretty easy to migrate an existing GMail account to another IMAP server, i.e. not GMail/Google server. There is an excellent synchronization tool – imapsync, which checks and downloads all the mails of an user account from one IMAP server to another IMAP server per user. The tool supports Google’s GMail accounts and their specific naming including the labels folders peculiarity (some folders in GMail may not have any physical emails, but just to show emails from another folders with specific labels). It’s worth mentioning that the imapsync works only only with GMail accounts, but it can be used to migrate from one IMAP server to another IMAP. The key here is the source and the destination server should support IMAP protocol.

Imapsync is an IMAP transfer tool. The purpose of imapsync is to migrate IMAP accounts or to backup IMAP accounts.

GMail will expose the labels as folders and in some early versions of the imapsync tool the emails with multiple labels may be shown in multiple folders and be duplicated. The version used here did not duplicate any email, even some emails were shown in multiple GMail folders.

There are two GMail settings to enable before proceeding with the migration:

Enable “Less secure app access” or if 2-Step-Verification is enabled use App Passwords
Enable IMAP, which is disabled by default.

SCREENSHOT 1) Manage the current Google account options by clicking on the top right corner as shown in the screenshot.

Recovery of MySQL 8 Cluster instance after server crash and corrupted data in log event

There is a MySQL 8 Cluster InnoDB of three servers and one of the server crashed with a bad RAM. The same setup is described here – Install and deploy MySQL 8 InnoDB Cluster with 3 nodes under CentOS 8 and MySQL Router for HA. The failed server got restarted without clean shutdown and after booting up the MySQL Cluster node tried to recover automatically, but the recover process failed and the node left the group of the three server:

2022-05-31T04:00:00.322469Z 24 [ERROR] [MY-011620] [Repl] Plugin group_replication reported: 'Fatal error during the incremental recovery process of Group Replication. The server will leave the group.'
2022-05-31T04:00:00.322489Z 24 [Warning] [MY-011645] [Repl] Plugin group_replication reported: 'Skipping leave operation: concurrent attempt to leave the group is on-going.'
2022-05-31T04:00:00.322500Z 24 [ERROR] [MY-011712] [Repl] Plugin group_replication reported: 'The server was automatically set into read only mode after an error was detected.'
2022-05-31T04:00:03.448475Z 0 [System] [MY-011504] [Repl] Plugin group_replication reported: 'Group membership changed: This member has left the group.'

The recovery process proposed here follows these steps

Connect with mysqlsh (MySQL Shell) to a MySQL instance, which is currently a part of the cluster group. The member, which left the group is not part any more, though the MySQL Cluster status shows it is part of the cluster topology, but with error.
Remove the bad instance from the MySQL Cluster with removeInstance
Add the instance with addInstance and the recovery process will kick in. The type of the recovery process will be chosen by the setup if not specified. In this case, the setup chooses the Incremental state recovery over (full) clone mode.
Initiate the cluster rescan operation to recovery the group replication and the MySQL Cluster.

mysql

Summery of the recovery process

The recovery process was successful.
The distributed recovery with Incremental state recovery has finished for 24 hours for 200Mbyte database, which is really strange and the speed was really bad. The instance uses ordinary disks, not SSDs and a 1Gbps network.
No need to change or manage the MySQL Router in any of the steps or the recovery stages. It handled the situation from the very beginning by removing the bad instance and then adding it again only after the recovery process had finished successfully.
MySQL Shell should be connected to an healthy instance currently a part of the Cluster.

In the console output logs all commands and important lines are highlighted.

STEP 1) Remove the bad instance from the cluster.

Install Fedora 36 KDE Plasma Desktop (KDE GUI)

This article will show the simple steps of installing a modern Linux Distribution like Fedora 36 KDE Plasma with KDE for the user graphical interface. First, it is offered the basic steps for installing the Operating system and then there are some screenshots of the installed system and the look and feel of it. Here is another article available with more screenshots of the installed and working Fedora 36 KDE Plasma – Review of freshly installed Fedora 36 KDE Plasma Desktop (KDE GUI). If the user is interested in Gnome as graphical interface there are two article how to install Fedora 36 Workstation Edition, which comes with GNOME and the look and feel of the GNOME – Install Fedora Workstation 36 (Gnome GUI) and Review of freshly installed Fedora 36 Workstation (Gnome GUI)
This is the simplest set up. One hard disk device in the system is installed, which is detected as sda and the entire disk will be used for the installation of Fedora 36 KDE Plasma. All disk information in sda disk device will be permanently deleted by the installation wizard!

The Fedora 36 KDE Plasma Desktop comes with

Xorg X server – 1.20.14 XWayland is used by default
linux kernel – 5.17.5
KDE Plasma version: 5.24.3
KDE Frameworks version: 5.91.0
QT version: 5.15.3

For more packages versions information check out the Fedora 36 server articles – Software and technical details of Fedora Server 36 including cockpit screenshots and Software comparison Ubuntu server 22.04 LTS vs Fedora 36 server edition – head-to-head.

We used the following ISO for the installation process:

https://download.fedoraproject.org/pub/fedora/linux/releases/36/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-36-1.5.iso

It is a LIVE image so you can try it before installing it. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

SCREENSHOT 1) Boot from the UEFI DVD-ROM device.

It is the same with the USB bootable removable drive. Choose the UEFI USB drive and boot the installation live drive.

Review of freshly installed Fedora 36 Workstation (Gnome GUI)

After the tutorial of Install Fedora Workstation 36 (Gnome GUI) this tutorial is mainly to see what to expect from a freshly installed Fedora 36 Workstation – the look and feel of the GUI (Gnome – version 42.1).

Xorg X server – 1.20.14
GNOME (the GUI) – 42.1
linux kernel – 5.17.5

More technical details here – Software and technical details of Fedora Server 36 including cockpit screenshots. The later article may be of interest to developers, too. The Fedora 36 Workstation may install all of the listed software for Fedora 36 Server Edition. The big difference is the disk layout and the file system used in the server edition and in workstation edition. By default, in Fedora 36 Workstation btrfs is used for the root and home mounts.
The idea of this tutorial is just to see what to expect from Fedora 36 Workstation (Gnome) – the look and feel of the GUI, the default installed programs, and their look and how to do some basic steps with them. Here the reader finds more than 140 screenshots and not so much text the main idea is not to distract the user with much text and version information and 3 meaningless screenshots, which the reader cannot see anything for the user interface, but these days the user interface is the primary goal of a Desktop system. More reviews of this kind will follow in the future …

For all installation and review articles, real workstations are used, not virtual environments!

SCREENSHOT 1) Fedora Linux (5.17.5-300.fc36.x86_64) 36 (Workstation Edition)
