Because OpenWrt uses its own init script system, all init scripts must be installed
|
|
as \texttt{/etc/init.d/\textit{name}} use \texttt{/etc/rc.common} as a wrapper.
|
|
|
|
Example: \texttt{/etc/init.d/httpd}
|
|
|
|
\begin{Verbatim}
|
|
#!/bin/sh /etc/rc.common
|
|
# Copyright (C) 2006 OpenWrt.org
|
|
|
|
START=50
|
|
start() {
|
|
[ -d /www ] && httpd -p 80 -h /www -r OpenWrt
|
|
}
|
|
|
|
stop() {
|
|
killall httpd
|
|
}
|
|
\end{Verbatim}
|
|
|
|
as you can see, the script does not actually parse the command line arguments itself.
|
|
This is done by the wrapper script \texttt{/etc/rc.common}.
|
|
|
|
\texttt{start()} and \texttt{stop()} are the basic functions, which almost any init
|
|
script should provide. \texttt{start()} is called when the user runs \texttt{/etc/init.d/httpd start}
|
|
or (if the script is enabled and does not override this behavior) at system boot time.
|
|
|
|
Enabling and disabling init scripts is done by running \texttt{/etc/init.d/\textit{name} enable}
|
|
or \texttt{/etc/init.d/\textit{name} disable}. This creates or removes symbolic links to the
|
|
init script in \texttt{/etc/rc.d}, which is processed by \texttt{/etc/init.d/rcS} at boot time.
|
|
|
|
The order in which these scripts are run is defined in the variable \texttt{START} in the init
|
|
script. Changing it requires running \texttt{/etc/init.d/\textit{name} enable} again.
|
|
|
|
You can also override these standard init script functions:
|
|
\begin{itemize}
|
|
\item \texttt{boot()} \\
|
|
Commands to be run at boot time. Defaults to \texttt{start()}
|
|
|
|
\item \texttt{restart()} \\
|
|
Restart your service. Defaults to \texttt{stop(); start()}
|
|
|
|
\item \texttt{reload()} \\
|
|
Reload the configuration files for your service. Defaults to \texttt{restart()}
|
|
|
|
\end{itemize}
|
|
|
|
You can also add custom commands by creating the appropriate functions and referencing them
|
|
in the \texttt{EXTRA\_COMMANDS} variable. Helptext is added in \texttt{EXTRA\_HELP}.
|
|
|
|
Example:
|
|
|
|
\begin{Verbatim}
|
|
status() {
|
|
# print the status info
|
|
}
|
|
|
|
EXTRA_COMMANDS="status"
|
|
EXTRA_HELP=" status Print the status of the service"
|
|
\end{Verbatim}
