X-Pack 插件在 docker 镜像中默认已安装,不过 X-Pack 中的 Security 模块需要付费才能使用,所以弃用这个插件。

Readonly REST 是 Elasticsearch 原生 REST API 的高性能权限控制插件。
Github 地址:https://github.com/sscarduzio/elasticsearch-readonlyrest-plugin
文档地址:https://github.com/beshu-tech/readonlyrest-docs/blob/master/elasticsearch.md
操作系统:centos 7.6
docker版本:19.03.12
ip地址:192.168.31.190
配置:1核2g
本文使用readonlyrest 插件来构建一个 Elasticsearch 镜像
这里使用最新版本,目前为:7.12.1
访问官方下载地址:https://readonlyrest.com/download/
注意:这里选择免费版本,指定版本为7.12.1,输入一个邮箱地址。这个邮箱地址可以是你的常用邮箱,比如QQ,163,新浪都可以。
点击GET IT NOW,就会收到一封邮件
点击邮件内容中的Download就会开启下载,这里我们会得到一个文件readonlyrest-1.29.0_es7.12.1.zip
登录到centos 7.6服务器,新建目录/opt/elasticsearch_7.12.1_security,将readonlyrest-1.29.0_es7.12.1.zip上传到此目录。
目录结构如下:
./ ├── dockerfile ├── readonlyrest-1.29.0_es7.12.1.zip └── readonlyrest.yml
dockerfile
FROM elasticsearch:7.12.1 COPY readonlyrest-1.29.0_es7.12.1.zip /plugins/readonlyrest-1.29.0_es7.12.1.zip RUN sh -c 'echo -e "y" | /usr/share/elasticsearch/bin/elasticsearch-plugin install -b file:///plugins/readonlyrest-1.29.0_es7.12.1.zip' COPY readonlyrest.yml /usr/share/elasticsearch/config/readonlyrest.yml
readonlyrest.yml
readonlyrest: access_control_rules: - name: "Require HTTP Basic Auth" type: allow auth_key: admin:Passw0rd
说明,这里指定用户名:admin,密码:Passw0rd
请根据实际情况修改
cd /opt/elasticsearch_7.12.1_security docker build -t elasticsearch:security-7.12.1 .
参考官方文档:https://www.elastic.co/guide/en/elasticsearch/reference/7.12/docker.html
修改文件 /etc/sysctl.conf
增加一行
vm.max_map_count=262144
刷新参数
sysctl -p
docker run -d --name=elasticsearch \ -p 9200:9200 -p 9300:9300 \ -e "discovery.type=single-node" \ -e "xpack.security.enabled=false" \ -e "TZ=Asia/Shanghai" \ elasticsearch:security-7.12.1
注意:启动时,一定要设置 xpack.security.enabled=false,否则启动会报错
uncaught exception in thread [main] java.lang.IllegalArgumentException: Cannot have more than one plugin implementing a REST wrapper at org.elasticsearch.action.ActionModule.<init>(ActionModule.java:448) at org.elasticsearch.node.Node.<init>(Node.java:575) at org.elasticsearch.node.Node.<init>(Node.java:278) at org.elasticsearch.bootstrap.Bootstrap$5.<init>(Bootstrap.java:217) at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:217) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:397) at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:159) at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:150) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:75) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:116) at org.elasticsearch.cli.Command.main(Command.java:79) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:115) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:81) For complete error details, refer to the log at /usr/share/elasticsearch/logs/docker-cluster.log
持久化存储的文件夹
mkdir -p /data/elk7/elasticsearch docker cp elasticsearch:/usr/share/elasticsearch /data/elk7/ chmod g+rwx -R /data/elk7/elasticsearch chgrp 1000 -R /data/elk7/elasticsearch
注意:由于docker运行中的elasticsearch用户id是1000,所以这里也设置1000
删除elasticsearch
docker rm -f elasticsearch
挂载目录方式启动
docker run -d --name=elasticsearch \ -p 9200:9200 -p 9300:9300 \ -e "discovery.type=single-node" \ -e "xpack.security.enabled=false" \ -e "TZ=Asia/Shanghai" \ -v /usr/share/elasticsearch:/data/elk7/elasticsearch \ -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \ elasticsearch:security-7.12.1
注意:关于ES_JAVA_OPTS参数,堆内存一般设置为内存的一半,请根据实际情况修改。
