Instalirajte Elasticsearch 7.3 na CentOS7

2020-01-14 15:52:48

oznaka: CentOS, Elasticsearch, CentOS7, Elasticsearch7.3, Instalirajte Elasticsearch, službeni Elasticsearch

Uredite datoteku /etc/yum.repos.d/elasticsearch.repo na sljedeći način:

[elasticsearch-7.x]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

Nakon instalacije YUM podesite postupak pokretanja i pokrenite uslugu.

yum -y install elasticsearch

systemctl daemon-reload
systemctl enable elasticsearch
systemctl start elasticsearch

Izmijenite konfiguracijsku datoteku /etc/elasticsearch/elasticsearch.yml

Dodajte konfiguraciju s autorizacijom ispod linije #secruity, spremite i izađite
network.host: 192.168.0.10

http.port: 9200

cluster.initial_master_nodes: ["node-1"]

Ponovo pokrenite elastično traženje i klijenta možete koristiti za daljinsko povezivanje.

[root@localhost ~]# systemctl restart elasticsearch

[root@localhost ~]# curl 192.168.0.10:9200
{
  "name" : "carbon",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "RmfeiseHQ8C5S9eF7gG6aQ",
  "version" : {
    "number" : "7.3.0",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "de777fa",
    "build_date" : "2019-07-24T18:30:11.767338Z",
    "build_snapshot" : false,
    "lucene_version" : "8.1.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}
[root@carbon ~]#

Problem: Nakon postavljanja provjere autorizacije također se uspostavljaju korisnik i lozinka, ali klijent se ne može povezati.

Rješenje: Zaustavite vatrozid
systemctl stop firewalld
systemctl stop iptables

Pitanje: Odziv kad pristupate ElasticSearch-u: Elasticsearch cluster 'master_not_discovered_exception'

Rješenje: Do ovog je problema došlo prilikom instaliranja Elasticsearch 7.5 u CentOS8. Razlog je taj što se čvorovi međusobno ne mogu otkriti. Ako postoji samo jedan čvor, možete izmijeniti konfiguracijsku datoteku i postaviti naziv čvora na node-1.

Preporuča se veličina predmemorije polja postaviti na 50% stvarne memorije.
vim /etc/elasticsearch/elasticsearch.yml

node.name: node-1

indices.fielddata.cache.size: 2gb
