推荐答案

假设您使用 rake install neo4j 任务安装了 Neo4j，请通过将 Web 浏览器指向 来确保服务器已启动http://localhost:7474.如果它没有运行，您需要解决与服务器无法启动相关的问题.

Assuming you installed Neo4j using the rake install neo4j task, make sure the server has started by pointing a web browser to http://localhost:7474. If it isn't running, you'll want to troubleshoot issues related to a server failing to start.

如果您从 neo4j.com 下载 Neo4j 2.2.0 或在过去一两天内使用过 brew，则需要转到该管理页面一次更改密码，然后在应用程序中进行设置，或者您可以完全按照 How to disable Basic在 Neo4j 2.2.0-RC01 上进行身份验证.在我的测试和开发环境中，我总是在 Neo4j 2.2.0 中禁用身份验证.

If you downloaded Neo4j 2.2.0 from neo4j.com or used brew within the last day or two, you'll need to go to that admin page once to change the password, then set it in the app, OR you can disable auth entirely as described at How to disable Basic Auth on Neo4j 2.2.0-RC01. I always disable auth in Neo4j 2.2.0 in my test and dev environments.
