引言：
在做练习项目的时候，需要使用Elasticsearch做搜索引擎。因为使用的是阿里云的服务器，为了更好的管理所以使用了Docker来安装Elasticsearch。但是本着安全性考虑，需要给Elasticsearch做安全验证。这时后难题来了，Elasticsearch默认的是不开启安全验证的，在网上找了很多文章和方法，均不行，各种报错。经过八九个小时的查找资料，算是总结出了自己亲自尝试的方法吧，希望能够帮到大家。

下载docker什么的大家都会我就不献丑了，就直接开始吧。

第一步：
我在网上查的，据说（未查找资料考证）Elasticsearch7.x.x之前好像是没有安全验证机制的。所以这里我使用的是7.6.2的版本，大家按我的步骤一步一步来吧。

下载镜像

docker pull docker.elastic.co/elasticsearch/elasticsearch:7.6.2

第二步：
创建elasticsearch.yml文件
个人习惯我是在 /home/user/elasticsearch/config 目录下创建的elasticsearch.yml文件，大家根据自己习惯来进行修改吧，或者按照我的步骤来。

配置elasticsearch.yml

http.host: 0.0.0.0
# Uncomment the following lines for a production cluster deployment
#transport.host: 0.0.0.0
#discovery.zen.minimum_master_nodes: 1
#Password config
xpack.security.enabled: true   #这一步是开启x-pack插件

创建docker

命令给你们，你们自己修改吧

docker run -d -it --restart=always --privileged=true --name=es7 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -v /home/user/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -e ES_JAVA_OPTS="-Xms256m -Xmx256m" f29a1ee41030

第三步：

进入容器并修改配置

docker exec -it es7 /bin/bash    # 进入容器
[root@f18d8bc7b8f5 elasticsearch]# cd bin 
[root@f18d8bc7b8f5 bin]# ls
elasticsearch           elasticsearch-croneval       elasticsearch-migrate        elasticsearch-setup-passwords    elasticsearch-syskeygen  x-pack-watcher-env
elasticsearch-certgen   elasticsearch-env            elasticsearch-node           elasticsearch-shard              elasticsearch-users
elasticsearch-certutil  elasticsearch-env-from-file  elasticsearch-plugin         elasticsearch-sql-cli            x-pack-env
elasticsearch-cli       elasticsearch-keystore       elasticsearch-saml-metadata  elasticsearch-sql-cli-7.6.2.jar  x-pack-security-env
[root@f18d8bc7b8f5 bin]# elasticsearch-setup-passwords interactive     #此步为手动设置密码
Initiating the setup of passwords for reserved users elastic,apm_system,kibana,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]y
Enter password for [elastic]:    #在这里设置密码，注意最少六位，下面也一样
Reenter password for [elastic]: 
Passwords do not match.
Try again.
Enter password for [elastic]: 
Reenter password for [elastic]:

Reenter password for [apm_system]:

Reenter password for [kibana]: 
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]
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@f18d8bc7b8f5 bin]# exit     #退出容器
