\n\n\n控制台配置项\n

控制台的一些特性可以通过配置项来进行配置，配置项主要有两个来源：System.getProperty() 和 System.getenv()，同时存在时后者可以覆盖前者。

\n
通过环境变量进行配置时，因为不支持 . 所以需要将其更换为 _。

配置项	类型	默认值	最小值	描述
auth.enabled	boolean	true	-	是否开启登录鉴权，仅用于日常测试，生产上不建议关闭
sentinel.dashboard.auth.username	String	sentinel	-	登录控制台的用户名，默认为 `sentinel`\n
sentinel.dashboard.auth.password	String	sentinel	-	登录控制台的密码，默认为 `sentinel`\n
sentinel.dashboard.app.hideAppNoMachineMillis	Integer	0	60000	是否隐藏无健康节点的应用，距离最近一次主机心跳时间的毫秒数，默认关闭
sentinel.dashboard.removeAppNoMachineMillis	Integer	0	120000	是否自动删除无健康节点的应用，距离最近一次其下节点的心跳时间毫秒数，默认关闭
sentinel.dashboard.unhealthyMachineMillis	Integer	60000	30000	主机失联判定，不可关闭
sentinel.dashboard.autoRemoveMachineMillis	Integer	0	300000	距离最近心跳时间超过指定时间是否自动删除失联节点，默认关闭
sentinel.dashboard.unhealthyMachineMillis	Integer	60000	30000	主机失联判定，不可关闭
server.servlet.session.cookie.name	String	sentinel_dashboard_cookie	-	控制台应用的 cookie 名称，可单独设置避免同一域名下 cookie 名冲突

配置示例：

命令行方式：

java -Dsentinel.dashboard.app.hideAppNoMachineMillis=60000

Java 方式：

System.setProperty(\"sentinel.dashboard.app.hideAppNoMachineMillis\", \"60000\");

环境变量方式：

sentinel_dashboard_app_hideAppNoMachineMillis=60000

\n\n\n命令行方式：\njava -Dsentinel.dashboard.app.hideAppNoMachineMillis=60000\nJava 方式：\nSystem.setProperty(\"sentinel.dashboard.app.hideAppNoMachineMillis\", \"60000\");\n环境变量方式：\nsentinel_dashboard_app_hideAppNoMachineMillis=60000\n\n\n更多配置项说明，可以访问官方网址：\nhttps://github.com/alibaba/spring-cloud-alibaba/blob/master/spring-cloud-alibaba-docs/src/main/asciidoc-zh/sentinel.adoc\n如果官方网址访问缓慢，可以访问下面老师的手记地址：\nhttps://www.imooc.com/article/289562\n\n\n配置方式\n

Sentinel 提供如下的配置方式：

JVM -D 参数方式
properties 文件方式（1.7.0 版本开始支持）

其中，project.name 参数只能通过 JVM -D 参数方式配置（since 1.8.0 取消该限制），其它参数支持所有的配置方式。

优先级顺序：JVM -D 参数的优先级最高。若 properties 和 JVM 参数中有相同项的配置，以 JVM 参数配置的为准。

用户可以通过 -Dcsp.sentinel.config.file 参数配置 properties 文件的路径，支持 classpath 路径配置（如 classpath:sentinel.properties）。默认 Sentinel 会尝试从 classpath:sentinel.properties 文件读取配置，读取编码默认为 UTF-8。

\n
注：1.7.0 以下版本可以通过旧的 ${user_home}/logs/csp/${project.name}.properties 配置文件进行配置（除 project.name 和日志相关配置项）。
\n

\n
注：若您的应用为 Spring Boot 或 Spring Cloud 应用，您可以使用 Spring Cloud Alibaba，通过 Spring 配置文件来指定配置，详情请参考 Spring Cloud Alibaba Sentinel 文档。
