ElasticSearch6.8.4&kibana6.8.4 installation tutorial

introduction

ElasticSearch 6.8.4 is installed on the client machine, so the local installation is used for stand-alone testing, so record it.
The Linux version in the virtual machine is centos7.

Depends on environment configuration

Install JDK

Install JDK tutorial, you can read my article: https://blog.csdn.net/weixin_52799373/article/details/126405150

Download the installation package

Download them all to /usr/local

elasticsearch

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.8.4.tar.gz

kibana

wget https://artifacts.elastic.co/downloads/kibana/kibana-6.8.4-linux-x86_64.tar.gz

Install

decompress

tar -zxvf elasticsearch-6.8.4.tar.gz

tar -zxvf kibana-6.8.4-linux-x86_64.tar.gz

After decompression:

install elasticsearch

Because of security issues, elasticsearch does not allow the root user to start, so create a new user to start elasticsearch.

# 添加用户
useradd elasticsearch
# 设置权限
chown -R elasticsearch:elasticsearch /usr/local/elasticsearch-6.8.4
chown -R elasticsearch:elasticsearch /usr/local/kibana-6.8.4-linux-x86_64

Start configuration tweaks

Edit vim /usr/local/elasticsearch-6.8.4/config/elasticsearch.ymlSet the startup ip and port. If not set, the default is localhost
to uncomment, or you can add it directly at the end. Feel free to add it later.

network.host: 192.168.169.131
http.port: 9200

System Configuration Adjustments

Modify the /etc/security/limits.conf file, add configuration, need to log in again to take effect

# 在文件末尾中增加下面内容
# 调整每个进程最大同时打开文件数,最大线程个数
# elasticsearch 前面创建的es用户
elasticsearch soft  nofile  65536
elasticsearch hard  nofile  65536
elasticsearch soft  nproc  4096
elasticsearch hard  nproc  4096

Modify the /etc/sysctl.conf file and add configuration

vm.max_map_count=262144

sysctl -p executes the command to take effect, otherwise it will fail.

Adjust es startup memory

vim /usr/local/elasticsearch-6.8.4/config/jvm.options

# 根据机器内存而定
-Xms256m
-Xmx256m

start up

Switch elasticsearch user:su elasticsearch

1. Normal startup: /usr/local/elasticsearch-6.8.4/bin/elasticsearch
   
   The startup is successful as shown in the above figure
   
   . Since the virtual machine has not opened the port yet, I directly access http://localhost:9200/ in the browser in the virtual machine, as shown in the above figure, it is successful.

2. Background start:/usr/local/elasticsearch-6.8.4/bin/elasticsearch -d

Install Kibana

Change setting

Modify /usr/local/kibana-6.8.4-linux-x86_64/config/kibana.yml to configure the port address of es. Since this file is all commented out, it is recommended to add the following content directly at the end:

server.host: "192.168.169.131"
elasticsearch.hosts: ["http://192.168.169.131:9200"]

start up

/usr/local/kibana-6.8.4-linux-x86_64/bin/kibana

Visit http://192.168.169.131:5601

to set Kibana to Chinese:vim /usr/local/kibana-6.8.4-linux-x86_64/config/kibana.yml

i18n.locale: "zh-CN"

The command started by kibana background

mkdir /usr/local/kibana-6.8.4-linux-x86_64/logs
mkdir /usr/local/kibana-6.8.4-linux-x86_64/pid
nohup /usr/local/kibana-6.8.4-linux-x86_64/bin/kibana >> /usr/local/kibana-6.8.4-linux-x86_64/logs/kibana.log 2>&1 & echo $! > /usr/local/kibana-6.8.4-linux-x86_64/pid/kibana.pid
