UCI system for OPENWRT firmware

UCI Systems
The "UCI" is the abbreviation for "Unified configuration Interface" (Unified Interface) and is intended to centralize the configuration of the entire system openwrt.

The system configuration should be easy, more straightforward and documented here, making your life easier!

(It is the successor improvement of the White Russian series OpenWrt NVRAM-based configuration.) ）

Many programs have their own configuration files somewhere in the system,

Like/etc/network/interfaces,/etc/exports,/etc/dnsmasq.conf or/etc/samba/samba.conf,

Sometimes they also use a slightly different syntax.

In OpenWrt you don't have to worry about this, we just need to change the UCI configuration file!

You don't need to restart the system for a change to work! See the command-line utilities later in this article to learn how to do this.

And don't forget that the official package (official binaries) contains a lot of background programs, but it is not enabled by default!

For example, the cron daemon is not activated by default, so editing only crontab is not useful.

You need to start it with/etc/init.d/crond or activate it with/etc/init.d/crond enable. Most background programs can be disable (disabled), stop (stop), and restart (restart). There are also some non-UCI configurations you can refer to.

Common principles

All OpenWrt configuration files are located in the/etc/config/directory. Each file is roughly related to the part of the system that it configures. You can edit/modify these configuration files by using a text editor, the UCI command-line utility, or various programming APIs such as Shell, Lua, and C.
