【问题描述】：

我在 ubuntu Amazon EC2 实例中运行 Neo4j 2.2.1。当我尝试使用 py2neo-2.0.7 通过 python 连接时，出现以下错误：

py2neo.packages.httpstream.http.SocketError: Operation not permitted

我可以通过http://52.10.**.***:7474/browser/访问网页界面

代码：-

from py2neo import Graph, watch, Node, Relationship

url_graph_conn = "https://neo4j:password@52.10.**.***:7474/db/data/"
print url_graph_conn
my_conn = Graph(url_graph_conn)
babynames = my_conn.find("BabyName")
for babyname in babynames:
    print 2

错误信息：-

【解决方案1】：

您正尝试在 http (7474) 的标准端口上通过 https 访问 neo4j：

url_graph_conn = "https://neo4j:password@52.10.**.***:7474/db/data/"

https 连接的标准端口是 7473。试试：

url_graph_conn = "https://neo4j:password@52.10.**.***:7473/db/data/"

并确保您可以通过 https 访问网络界面：

https://52.10.**.***:7473/browser/

您可以在 neo4j-server.properties 文件中更改/查看端口设置。
