The server section of the Nginx UI configuration deals with various settings that control the behavior and operation of the Nginx UI server. In this section, we will discuss the available options, their default values, and their purpose.


  • Type: int
  • Default: 9000

Nginx UI server listen port. This option is used to configure the port on which the Nginx UI server listens for incoming HTTP requests. Changing the default port can be useful for avoiding port conflicts or enhancing security.


  • Type: string
  • Supported value: release, debug


At present, we have not yet adapted to this option, and there will be no significant differences between release and debug in terms of usage.


  • Type: int
  • Default: 9180

This option is used to set the port for backend listening in the HTTP01 challenge mode when obtaining Let's Encrypt certificates. The HTTP01 challenge is a domain validation method used by Let's Encrypt to verify that you control the domain for which you're requesting a certificate.


  • Type: string
  • Default: database

This option is used to set the name of the sqlite database used by Nginx UI to store its data.


  • Type: string
  • Default: login

This option is used to set the start command of the web terminal.


For security reason, we use login as the start command, so you have to log in via the default authentication method of the Linux. If you don't want to enter your username and password for verification every time you access the web terminal, please set it to bash or zsh (if installed).


  • Type: int
  • Default: 10

This option is used to set the page size of list pagination in the Nginx UI. Adjusting the page size can help in managing large amounts of data more effectively, but a too large number can increase the load on the server.


  • Type: string

When applying for a Let's Encrypt certificate, we use the default CA address of Let's Encrypt. If you need to debug or obtain certificates from other providers, you can set CADir to their address.


Please note that the address provided by CADir needs to comply with the RFC 8555 standard.


  • Type: string
  • Suggestion:

For users who may experience difficulties downloading resources from Github (such as in mainland China), this option allows them to set a proxy for to improve accessibility.
