DA-710 Series Linux
Software Configuration
2-8
To run a private daemon, you can edit the file
rc.local
as follows:
1.
Because the root file system is mounted in Read-only mode, you need to re-mount it with write permission.
MOXA:~# mount -o remount,rw /dev/hda1 /
2.
Type
cd /etc/
to change directories.
MOXA:~# cd /etc/
3.
Type
vi rc.local
to edit the configuration file with vi editor.
MOXA:/etc/# vi rc.local
4.
Next, add the application daemon that you want to run. We use the example program
tcps2-release
which
you can find in the CD to illustrate, and configure it to run in the background.
# !/bin/sh
# Add you want to run daemon
/root/tcps2-release &~
5.
After you finish writing or modifying the code, remember to execute “umount /” to change the root directory
back to Read-only mode.
MOXA:~# umount /
6.
You should be able to find the enabled daemon after you reboot the system.
MOXA:~# ps -ef
