[英]Start Cosmos-GUI
I want to install Cosmos. 我想安装Cosmos。 I have installed Apache-Hadoop 2.6 with a single node and my next move was install cosmos-gui. 我已经用一个节点安装了Apache-Hadoop 2.6,我的下一步是安装cosmos-gui。
So I follow the official installation guide - https://github.com/telefonicaid/fiware-cosmos/blob/develop/cosmos-gui/README.md#installation but npm start
command doesn't work. 所以我按照官方安装指南 - https://github.com/telefonicaid/fiware-cosmos/blob/develop/cosmos-gui/README.md#installation但是npm start
命令不起作用。

As the installation guide says: 正如安装指南所说:
- private_key_file: File name containing the private key used to encrypt the communications with the clients. private_key_file:包含用于加密与客户端通信的私钥的文件名。
- certificate_file: File name containing the self-signed X509 certificate used by the server to send the clients the public counterpart of the above private key (see Annex B]. certificate_file:包含服务器用于向客户端发送上述私钥的公共副本的自签名X509证书的文件名(参见附录B)。
So, you have to configure the private_key_file
and the certificate_file
configuration parameters. 因此,您必须配置private_key_file
和certificate_file
配置参数。 You can follow this link in order to know how to create the key and a self-signed certificate. 您可以按照此链接了解如何创建密钥和自签名证书。
EDIT 1 编辑1
Once configured the above files, the user will experience an error related to the binding of a port under 1024 being a non root user. 一旦配置了上述文件,用户将遇到与作为非root用户的1024下的端口绑定相关的错误。
This can be fixed, of course, by configuring a port over 1024; 当然,这可以通过配置超过1024的端口来修复; or setting this capability: setcap 'cap_net_bind_service=+ep' /path/to/program
; 或设置此功能: setcap 'cap_net_bind_service=+ep' /path/to/program
; or doing IP forwarding (preferred method). 或进行IP转发(首选方法)。
Start the GUI in a port over 1024, eg 9090
, and run this commands in order to configure IP forwarding: 在1024以上的端口启动GUI,例如9090
,并运行此命令以配置IP转发:
$ iptables -A PREROUTING -t nat -p tcp --dport 443 -j REDIRECT --to-port 9090
Then, you can type https://<host_running_the_gui>
in your browser and the traffic will be automatically forwarded to the real listening port (in the example, 9090
). 然后,您可以在浏览器中键入https://<host_running_the_gui>
,流量将自动转发到真实的侦听端口(例如, 9090
)。
