ElasticSearch之安装

参照Installing Elasticsearch，完成验证集群的部署。

操作步骤

下载软件包和摘要文件。

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.11.1-linux-x86_64.tar.gz
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.11.1-linux-x86_64.tar.gz.sha512

校验压缩包的完整性。

shasum -a 512 -c elasticsearch-8.11.1-linux-x86_64.tar.gz.sha512

解压软件包。

tar -xzf elasticsearch-8.11.1-linux-x86_64.tar.gz

启动elasticsearch服务。

cd elasticsearch-8.11.1/
export ELASTIC_PASSWORD="espass"
./bin/elasticsearch

修改口令。注意需要新开一个shell命令行窗口。

./bin/elasticsearch-reset-password -u elastic

命令的输出如下：

This tool will reset the password of the [elastic] user to an autogenerated value.
The password will be printed in the console.
Please confirm that you would like to continue [y/N]yPassword for the [elastic] user successfully reset.
New value: ohCxPH=QBE+s5=*lo7F9

得到新的口令为ohCxPH=QBE+s5=*lo7F9。

检查服务是否可用。

export ES_HOME=~/elasticsearch-8.11.1
curl --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9" https://localhost:9200

输出如下：
