问题描述：

python运行neo4j报错：

py2neo.database.work.ClientError: [Security.Unauthorized] The client is unauthorized due to authentication failure.

解决办法：

1、调整neo4j安装目录/conf/neo4j.conf文件相关配置为下图所示：

#*****************************************************************
# Network connector configuration
#*****************************************************************

# With default configuration Neo4j only accepts local connections.
# To accept non-local connections, uncomment this line:
dbms.connectors.default_listen_address=0.0.0.0

# You can also choose a specific network interface, and configure a non-default
# port for each connector, by setting their individual listen_address.

# The address at which this server can be reached by its clients. This may be the server's IP address or DNS name, or
# it may be the address of a reverse proxy which sits in front of the server. This setting may be overridden for
# individual connectors below.
dbms.connectors.default_advertised_address=localhost

# You can also choose a specific advertised hostname or IP address, and
# configure an advertised port for each connector, by setting their
# individual advertised_address.


# Bolt connector
dbms.connector.bolt.enabled=true
dbms.connector.bolt.tls_level=OPTIONAL
dbms.connector.bolt.listen_address=:7687

# HTTP Connector. There can be zero or one HTTP connectors.
dbms.connector.http.enabled=true
dbms.connector.http.listen_address=:7474

# HTTPS Connector. There can be zero or one HTTPS connectors.
dbms.connector.https.enabled=true
dbms.connector.https.listen_address=:7473

2、ctrl+C，关闭neo4j数据库

3、其他过程：

1，通过控制台启动Neo4j程序

点击组合键：Windows+R，输入cmd，启动DOS命令行窗口，切换到主目录，以管理员身份运行命令：

neo4j.bat console
2，把Neo4j安装为服务（Windows Services）

安装和卸载服务：

bin\neo4j install-service
bin\neo4j uninstall-service
启动服务，停止服务，重启服务和查询服务的状态：

bin\neo4j start
bin\neo4j stop
bin\neo4j restart
bin\neo4j status
3，浏览器打开neo4j：

Neo4j服务器具有一个集成的浏览器，在一个运行的服务器实例上访问 “http://localhost:7474/”，打开浏览器，显示启动页面
