How To Setup Elasticsearch 6.4 On RHEL/CentOS 6/7?
What is Elasticsearch?
Elasticsearch is a search engine based on Lucene. It is useful in a distributed environment and helps in a multitenant-capable full-text search engine. While you query something from Elasticsearch it will provide you with an HTTP web interface and schema-free JSON documents. it provides the ability for full-text search. Elasticsearch is developed in Java and is released as open-source under the terms of the Apache 2 license.
Scenario:
1. Server IP: 192.168.56.101
2. Elasticsearch: Version 6.4
3. OS: CentOS 7.5
4. RAM: 4 GB
Note: If you are a SUDO user then prefix every command with sudo, like #sudo ifconfig
With the help of this guide, you will be able to set up Elasticsearch single-node clusters on CentOS, Red Hat, and Fedora systems.
Step 1: Install and Verify Java
Java is the primary requirement for installing Elasticsearch. So, make sure you have Java installed on your system.
# java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)
If you don’t have Java installed on your system, then run the below command
# yum install java-1.8.0-openjdk
Step 2: Setup Elasticsearch
For this guide, I am downloading the latest Elasticsearch tar from its official website so follow the below step
# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.2.tar.gz
# tar -xzf elasticsearch-6.4.2.tar.gz
# tar -xzf elasticsearch-6.4.2.tar.gz
# mv elasticsearch-6.4.2 /usr/local/elasticsearch
Step 5: Permission and User
We need a user for running elasticsearch (root is not recommended).
# useradd elasticsearch
# chown -R elasticsearch.elasticsearch /usr/local/elasticsearch/
Step 6: Setup Ulimits
Now to get a Running system we need to make some changes of ulimits else we will get an error like “max number of threads for user is too low, increase to at least ” so to overcome this issue make below changes you should run.
# ulimit -n 65536
# ulimit -u 2048
Or you may edit the file to make changes permanent
# vim /etc/security/limits.conf
elasticsearch - nofile 65536
elasticsearch soft nofile 64000
elasticsearch hard nofile 64000
elasticsearch hard nproc 4096
elasticsearch soft nproc 4096
Save files using :wq
Step 7: Configure Elasticsearch
Now make some configuration changes like cluster name or node name to make our single node cluster live.
# cd /usr/local/elasticsearch/
Now, look for the below keywords in the file and change according to you need
# vim conf/elasticsearch.yml
cluster.name: kapendra-cluster-1
node.name: kapendra-node-1
http.port: 9200
to set this value to your IP or make it 0.0.0.0 ID needs to be accessible from anywhere from the network. Else put your IP of localhost
network.host: 0.0.0.0
There is one more thing if you have any dedicated mount pint for data then change the value for
#path.data: /path/to/data to your mount point.
Your configuration should look like the above.
Step 8: Starting Elasticsearch Cluster
As the Elasticsearch setup is completed. Let the start Elasticsearch cluster with elastic search user so first switch to elastic search user and then run the cluster
# su - elasticsearch
$ /usr/local/elasticsearch/bin/elasticsearch
22278
Step 9: Verify Setup
You have all done it, just need to verify the setup. Elasticsearch works on port default port 9200, open your browser to point your server on port 9200, You will find something like the below output
http://localhost:9200 or http://192.168.56.101:9200
at the end of this article, you have successfully set up Elasticsearch single node cluster. In the next few articles, we will try to cover a few commands and their setup in the docker container for development environments on local machines.

FI_PROVIDER = tcp
Mpirun -n 2 -ppn 1 -bind-to core -hostfile is the command line. IMB-MPI1 Pingpong -iter 50000 -msglog 0:16
AllReduce – Intel MPI Benchmark (IMB) – single process per node
The collective latency across multiple ranks across virtual machines is measured by the IMB AllReduce benchmark. It uses the MPI_SUM operation to reduce a vector with a fixed length.
Initially, they display 1 PPN (process-per-node) result (1 MPI rank) on 8 VMs in order to isolate networking performance.
When comparing the HPC Rocky Linux 8 image to the default GCP Rocky Linux 8 image, they observed improvements of up to 35%.
Setting up benchmarks
Eight times the h3-standard-88
Every node has one process.
Intel OneAPI MPI library 2021.11.0 is the MPI library.
Intel MPI Benchmarks 2019 Update 6 is the MPI benchmarks application.
Environment variables for MPI:

Google is pleased to announce today the general availability of HPC Virtual Machine (VM) images for workloads involving high performance computing (HPC), primarily tightly coupled workloads like fluid dynamics, molecular modeling, and weather forecasting. These images are based on CentOS 7 and Rocky Linux 8.
They have made it simple to create an HPC-ready virtual machine instance using the HPC VM image by integrating their finest practices for HPC on Google Cloud, such as:
Virtual machines prepared for HPC right out of the box
Virtual machines prepared for HPC right out of the box For closely coupled HPC workloads, there’s no need to manually adjust performance, handle virtual machine reboots, or stay current with Google Cloud updates especially with their frequent releases of HPC VM images. As soon as tunings call for them, the HPC VM image will take care of the reboot process automatically.
Optimization of networking for closely coupled workloads
Networking best practices for workloads that are closely connected Applications that heavily rely on point-to-point and collective communications benefit from optimizations that lower latency for small messages.
Compute optimizations
These include adjustments to lessen system jitter, which improves scalability by ensuring consistent single-node performance.
Enhanced application compatibility
A high level of system interoperability is made possible by alignment with the node-level specifications of the Intel HPC platform specification.
Measuring performance with HPC benchmarks
They have evaluated the HPC VM images’ performance using the Intel MPI Benchmarks (IMB) against the GCP-optimized Rocky Linux 8 image and the default CentOS 7 image.
The following images served as the benchmarks.
Rocky Linux 8 for HPC
hpc-rocky-linux-8-v20240126 is the image name.
The cloud-hpc-image-public image project
GCP Rocky Linux 8 default
Rocky-linux-8-optimized-gcp-v20240111 is the image name.
Picture project: cloud-linux-rocky
In order to reduce network latency, each cluster of machines was deployed using compact placement with max_distance=1, which meant that all virtual machines were situated on hardware that was physically on the same rack
The HPC VM image and the Cloud HPC Toolkit
The Cloud HPC Toolkit, an open-source tool that makes it easier to deploy environments for a range of workloads, including machine learning, AI, and HPC, is where you can use the HPC VM image. Actually, the HPC VM image is used by default by the Toolkit blueprints and Slurm images based on CentOS 7 and Rocky Linux 8. The HPC VM image can be further customized with the help of the Cloud HPC Toolkit, allowing for the installation of additional software and configuration changes, thus increasing its utility.
It is possible to create and share blueprints for creating optimized and specialized images, increasing reproducibility while lowering setup time and effort, by using the Cloud HPC Toolkit to customize images based on the HPC VM Image.
Setting up an HPC-ready VM
Overview
In tightly coupled high performance computing (HPC) workloads, processes and VM instances communicate via MPI.. However, creating your own VM image that is optimized for MPI performance calls for additional maintenance time, familiarity with Google Cloud, and system knowledge. You can use the HPC VM image to quickly create virtual machine instances for your HPC workloads. A substitute is to use the H3 machine series to build virtual machines (VMs).
The HPC virtual machine image is designed for tightly coupled HPC workloads and is based on either CentOS 7.9 or Rocky Linux 8. It contains pre-configured network and kernel tuning parameters needed to build virtual machines (VM instances) with the best MPI performance on Google Cloud
These options can be used to create a virtual machine that is ready for HPC:
Cloud CLI for Google
Google Cloud interface. The image can be accessed in the console via Cloud Marketplace.
Slurm, the workload manager from SchedMD, defaults to using the HPC VM image.
Omnibond CloudyCluster defaults to using the HPC VM image.
Advantages
The advantages of the HPC VM image are as follows:
Virtual machines that are ready for HPC right out of the box
For closely coupled HPC workloads, there’s no need to manually adjust performance, handle virtual machine reboots, or keep up with Google Cloud updates.
Networking best practices for workloads that are closely connected
Applications that heavily rely on point-to-point and collective communications benefit from optimizations that lower latency for small messages.
Computation-related improvements for HPC tasks
The inclusion of jitter reduction optimizations increases the predictability of single-node high performance.
reliable and consistent performance. Application-level performance is consistent and repeatable with VM image standardization.
enhanced compatibility with applications. System interoperability is greatly enhanced by alignment with the node-level requirements of the Intel HPC platform specification.
Features
Collective tunings for Intel MPI
Compact placement policies were used to perform Intel MPI collective tunings on c2-standard-60 and c2d-standard-112 instances, which are included in the HPC VM image.
RPMs that are already installed
The RPM packages listed below are pre-installed on the HPC virtual machine image
Package group “Development Tools” contains the following: Lmod, dkms, htop, hwloc, hwloc-devel, kernel-devel, ltrace, libXt, nfs-utils, numptl, numptl-devel, papi, pciutils, pdsh, perf, redhat-lsb-core, redhat-lsb-cxx, rsh, screen, trace, wget, zsh

まだ /usr/lib/systemd/system のサービス設定ファイルを編集しているの？
CentOS7(RHEL)やUbuntu(Debian)などのsystemdでサービス起動している設定ファイル（ユニットファイル）を書き換えるときの注意点をまとめました。
Zabbix-Agentをroot起動したいときに `zabbix-agentd.conf` の `AllowRoot=1` にしただけじゃ足りず、`/usr/lib/systemd/system/zabbix-agent.service` で設定しているユーザー、グループを書き換える、ありますよね？
でもその方法、合ってますか？ https://tamulab.jp/systemd-unit-files-configure/?utm_source=dlvr.it&utm_medium=tumblr

Vmware fusion m1 macos

Vmware fusion m1 macos full#
From your macOS VM, follow the instructions on Enroll Your Devices – To Get Public Beta Software. It is with great pride and pleasure that we announce the public availability of VMware Fusion for Apple Silicon Public Tech Preview With more than a year in development, and a few weeks of a successful Private Tech Preview, it’s finally time for us to show the world what we’ve been working on.
Read over the Apple Guide for Public Betas.
Sign up for the Apple Beta Software Program.
It’s pretty straightforward to get Apple OS betas. And that’s really unnecessary anyway, because you can safely run just about any OS in a VM. For the host OS, I strongly recommend against running a beta or any unsupported OS as the host. As both Parallels Desktop and VMware Fusion have both been updated, it’s worth revisiting that blog. My blog from February compared the options available at the time. However, it’s also pretty normal in my experience that running beta OSes as a guest in a VM works fine. Virtual machines are usually more productive for those types of activities, hence my desire to run virtual machines on my M1 Mac Mini.

When you fetch the full installer installing just means. Once the download is complete, it will stop with the installing percentage: Don’t be alarmed by the term Installing. When brand new OSes are released in betas, it is normal that VMware and Parallels don’t say too much about them, and do not officially support running them as a guest OS in a VM, and especially not as a host OS. If you are using an M1-based Macintosh, you wont be able to use the standard VMWare Fusion Player for Intel-based Macs. There’s a way built into macOS to get the installer using the softwareupdate -fetch-full-installer command in Applications > Utilities > Terminal. I wound up just buying a refurb'd PC and using Remote Desktop to access it over my local network from my M1 mini. Windows for ARM is not officially Supported, but you can read posts in that forum for help. Mac Pro M1 (ARM) installation: VMware fusion and Linux (centos7 / ubantu) (I).
Vmware fusion m1 macos install#
Since I do a lot of testing and development on various OSes and apps, I have an up to date base install of macOS Big Sur, Catalina and more ready to go at all times in a Virtual Machine (VM). The only version of Fusion which will run on an M1 Mac is the Tech Preview for Apple Silicon.
