ElasticStack----使用Docker方式安装单节点的8.1.3版本的ElasticSearch

1 -镜像

docker

2 创建挂载目录，将数据盘挂载出来

mkdir -p /docker/elasticsearch/usr/share/elasticsearch/datachmod 777

3 创建docker启动Elasticsearch服务

docker run -d --name elasticsearch -p 10013:9200 -p 10014:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms512m -Xmx1024m" -e "--privileged --restart=always -v /docker/elasticsearch/usr/share/elasticsearch/data:/usr/share/elasticsearch/data docker.elastic.co/elasticsearch/elasticsearch:8.1.3

4 Elasticsearch从8开始不再提供默认密码，这里需要重置密码

使用如下命令一次性将 elastic，apm_system，kibana，kibana_system，logstash_system，beats_system，remote_monitoring_user 等用户密码都重新设置

docker exec

如下依次输入各个用户的密码，当然也可以设置为一个，自己需要记住：

[root@redrose2100 ~]# docker exec -it elasticsearch /usr/share/elasticsearch/bin/elasticsearch-setup-passwords interactive******************************************************************************Note: The 'elasticsearch-setup-passwords' tool has been deprecated. This command will be removed in a future release.******************************************************************************Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user.You will be prompted to enter passwords as the process progresses.Please confirm that you would like to continue [y/N]yEnter password for [elastic]:Reenter password for [elastic]:Enter password for [apm_system]:Reenter password for [apm_system]:Enter password for [kibana_system]:Reenter password for [kibana_system]:Enter password for [logstash_system]:Reenter password for [logstash_system]:Enter password for [beats_system]:Reenter password for [beats_system]:Enter password for [remote_monitoring_user]:Reenter password for [remote_monitoring_user]:Changed password for user [apm_system]Changed password for user [kibana_system]Changed password for user [kibana]Changed password for user [logstash_system]Changed password for user [beats_system]Changed password for user [remote_monitoring_user]Changed password for user [elastic][root@redrose2100 ~]#

5 由于Elasticsearch从8开始启用了安全证书机制，将证书拷贝到宿主机

mkdir -p /docker/elasticsearch/usr/share/elasticsearch/config/certsdocker cp

6 在命令行使用如下命令验证Elasticsearch是否安装成功

使用如下命令，然后在交互环境根据提示输入上面重置后的密码

curl

过程如下：

[root@redrose2100 ~]# curl --cacert /docker/elasticsearch/usr/share/elasticsearch/config/certs/-u elastic host password for user 'elastic':{ "name" : "994bcface178", "cluster_name" : "docker-cluster", "cluster_uuid" : "xOFaXy78QxWuJ8b-qcUF1g", "version" : { "number" : "8.1.3", "build_flavor" : "default", "build_type" : "docker", "build_hash" : "39afaa3c0fe7db4869a161985e240bd7182d7a07", "build_date" : "2022-04-19T08:13:25.444693396Z", "build_snapshot" : false, "lucene_version" : "9.0.0", "minimum_wire_compatibility_version" : "7.17.0", "minimum_index_compatibility_version" : "7.0.0" }, "tagline" : "You Know, for Search"}[root@redrose2100 ~]#

7 至此，Elasticsearch 8.1.3版本的安装就已经成功完成了

8 若后期想单独修改某个用户的密码时，使用如下命令即可

如下为修改用户elastic的密码

docker exec

9 为了简单使用，也可以将使用认证的开关关掉，首先将ElasticSearch中的配置文件拷贝出来

docker cp

10 编辑配置文件，

vi

将如下位置的配置的true修改为false

11 然后使用如下命令将修改后的配置重新拷贝到docker容器中

docker cp

12 重启docker

docker

13 此时，直接使用如下命令再次请求Elasticsearch，即不适用证书直接请求

curl

结果如下：

Enter host password for user 'elastic':{ "name" : "994bcface178", "cluster_name" : "docker-cluster", "cluster_uuid" : "xOFaXy78QxWuJ8b-qcUF1g", "version" : { "number" : "8.1.3", "build_flavor" : "default", "build_type" : "docker", "build_hash" : "39afaa3c0fe7db4869a161985e240bd7182d7a07", "build_date" : "2022-04-19T08:13:25.444693396Z", "build_snapshot" : false, "lucene_version" : "9.0.0", "minimum_wire_compatibility_version" : "7.17.0", "minimum_index_compatibility_version" : "7.0.0" }, "tagline" : "You Know, for Search"}[root@redrose2100 elasticsearch]#
