Shield是Elasticsearch一个安全防护插件,提供了权限访问控制和日志审计功能,企业可以很方便的和LDAP或是ActiveDirectory进行集成,重用现有的安全认证体系.
Elasticsearch使用了Shield后,Elasticsearch就需要权限才能访问了,和默认的调用方式有些不同,下面简单介绍一下HTTP和TCP两种方式的连接.
关于Shield的安装和配置我这里不就具体介绍,创建了一个用户名和密码都是tribe_user的用户,权限是admin.
1.HTTP方式
现在直接访问es的http接口就会报错
curl http://localhost:9200
{"error":{"root_cause":[{"type":"security_exception","reason":"missing authentication token for REST request [/]","header":{"WWW-Authenticate":"Basic realm=\"shield\""}}],"type":"security_exception","reason":"missing authentication token for REST request [/]","header":{"WWW-Authenticate":"Basic realm=\"shield\""}},"status":401}
shield支持HttpBasic验证,所以正确的访问姿势是:
curl -u tribe_user:tribe_user http://localhost:9200 { "name" : "Melter", "cluster_name" : "elasticsearch", "version" : { "number" : "2.1.1", "build_hash" : "805c528f3167980046f224310f9147fa745e5371", "build_timestamp" : "2015-12-09T20:23:16Z", "build_snapshot" : false, "lucene_version" : "5.3.1" }, "tagline" : "You Know, for Search" }
如果是浏览器访问的话,第一次访问会弹出验证窗口,后续只要不关闭这个浏览器保持这个session就能一直访问.
注意http basic是不安全的认证方式,仅供开发调试使用,生产环境还需要结合HTTPS的加密通道使用.
2.TransportClient方式的访问Shield加防的Elasticsearch,稍微麻烦点,需要依赖Shield的包,步骤如下:
2.1 如果你是maven管理的项目,在pom.xml文件里添加Elasticsearch的maven仓库源,如下:
<repositories>
<repository>
<id>elasticsearch-releases</id>
<url>https://maven.elasticsearch.or ... gt%3B
<releases> <enabled>true</enabled> </releases>
<snapshots> <enabled>false</enabled> </snapshots>
</repository>
</repositories>
2.2 添加依赖的配置
<dependency>
<groupId>org.elasticsearch.plugin</groupId>
<artifactId>shield</artifactId>
<version>2.1.1</version>
</dependency
2.3 构建TransportClient的地方增加访问用户的配置
import org.elasticsearch.shield.ShieldPlugin; import org.elasticsearch.shield.authc.support.SecuredString; import static org.elasticsearch.shield.authc.support.UsernamePasswordToken.basicAuthHeaderValue;
String clusterName="elasticsearch"; String ip= "127.0.0.1";
Settings settings = Settings.settingsBuilder()
.put("cluster.name", clusterName)
.put("shield.user", "tribe_user:tribe_user")
.build();
try { client = TransportClient.builder()
.addPlugin(ShieldPlugin.class)
.settings(settings).build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(ip),9300));
String token = basicAuthHeaderValue("tribe_user", new SecuredString("tribe_user".toCharArray())); client.prepareSearch()
.putHeader("Authorization", token).get(); }
catch (UnknownHostException e)
{ logger.error("es",e); }
现在的编辑器贴代码有点恶心,可以看这里:
