Install

The only requirement for installing Elasticsearch is Java. You can download the latest version from the official website, including zip, tar, deb, rpm, and other versions.

# curl -L -O https://download.elastic.co/elasticsearch/***/elasticsearch-***.rpm

Install

# rpm -ivh elasticsearch-***.rpm

Start the service

After the installation is successful, you will be prompted to usesystemctl start elasticsearch.serviceStart the service and usesystemctl status elasticsearch.serviceView service status

In this case, use "localhost: 9200" as prompted to access the service.

Configure Remote Access

If remote access is added (1) modify the configuration file

vi /etc/elasticsearch/elasticsearch.yml 

Modify network. host to the server IP address. If you need to customize the port, you can modify the http. port parameter.

(2) Add port access

Firewall-cmd -- list-all (view rules) firewall-cmd -- add-port = 6379/tcp -- permanentfirewall-cmd -- reload

Now you can use the address and port number for remote access.
