start up script

start up script

[- Luis -]

Hi all, i want to add a script to the start up in my Red Hat box, but i 
already put the file in /etc/rc.d/init.d and make the symbolic link in 
/etc/rc3.d/S55routetable.

But still doesn't work, if i run the script manually, it runs just fine, but 
when i restart the server i doesn't run.  

Basically the script is for adding some routes to my server.

Thanks

It should probably be "/etc/rc.d/rc3.d/S55routetable".

Is the script relying upon environment settings which are only present
in an interactive shell? Scripts which are run from init tend to have
a relatively empty environment; e.g. PATH may not contain /sbin or
/usr/sbin, etc.

Does the script work if you use e.g.

	env -i /etc/rc.d/init.d/routetable start

?

Re: start up script

[freddie]

does your script start with #!/bin/bash (or equivalent)?
also use full paths. for example in your script "sed blahblahblah" will 
work when you run it by hand but not during boot. "/usr/sbin/sed 
balhblahblah" would work for both.
when you run something manually you have your whole environment set up. 
when a script is run during bootup it doesnt.

This is my script:

#!/bin/bash
/sbin/route add -net 10.3.1.0 netmask 255.255.255.0 gw 10.1.1.250
/sbin/route add -net 10.4.1.0 netmask 255.255.255.0 gw 10.1.1.250
/sbin/route add -net 10.8.1.0 netmask 255.255.255.0 gw 10.1.1.250

and its place in /etc/rc.d/init.d/routetable and the link its in 
/etc/rc.d/rc3.d/S55routetable

but i run it only executing /etc/rc.d/init.d/routetable as root

how does it work chkconfig? or do i have to place this script in somewhere 
else?

Thanks

There is more to writing a startup script than that.

I don't think it should make a difference at this point, unless your 
network isn't running by S55.  Are you sure you are starting only at run 
level 3?

>how does it work chkconfig? or do i have to place this script in somewhere

man chkconfig
It's a very handy tool for administering run level services.

Didn't you say you were running a RedHat box?  Version number would be 
useful information, however, check to see if you have the file:
  /etc/sysconfig/static-routes

in it, add the line:
eth0 net 10.0.0.0 netmask 255.0.0.0 gw 10.1.1.250

>As long as eth0 is the NIC connected to 10.1.1.250

/etc/init.d/network script reads this file for you, and does it in the 
right place, and the next person to admin this RedHat box will know where 
to look with out a bunch of fumbling around.

Good luck.

Scott.

Thanks Scott, that static-routes file will make my day, but i look in 
/etc/sysconfig and is not there, can i just create one and restart the 
network services, or is more complicated than that?

Re: start up script

[Jeff Largent]

The static-routes file based on your route statements would look
like:
eth0 net 10.3.1.0 netmask 255.255.255.0 gw 10.1.1.250
ech0 net 10.4.1.0 netmask 255.255.255.0 gw 10.1.1.250
eth0 net 10.8.1.0 netmask 255.255.255.0 gw 10.1.1.250

the answer is yes if the file dosn't exist create it and
just restart network "service network restart"

Re: start up script

[terry white]

... ciao:

    "man chkconfig" is the first thing to do.

    basically, chkconfig manages services when the runlevel changes.  it
requires a file for each service it manages, and that file has a specific
format.  that format is defined (RH at least) in 'sysvinitfiles'.  a
"locate sysvinitfiles" should point you in the right direction.  the file
makes a handy template, for the cut-n-paste advocate.

    given your preference, the file you create will be called
'routetable', and "chkconfig --add routetable" should handle all the
housekeeping chores.  however, the file supports a 'case' statement
allowing several possible invocations, and it is your responsibility to
provide for the ones you use.  specifically, you might well consider
using a 'route -del blah' to remove routes you've created when the
interface comes down.


: the link its in /etc/rc.d/rc3.d/S55routetable

    i'd rm that before you invoke chkconfig on 'routetable' ...

chkconfig just adds and removes the symlinks. It relies upon the
script having a line like this:

	# chkconfig: 2345 05 92

near the top of the script.

The first field ("2345") is the default list of runlevels for which
that script will be run. The second field is the start order, and
the third is the stop order (i.e. the numbers in the "S" and "K"
symlinks respectively).

chkconfig is just for convenience. You don't have to use chkconfig;
creating the symlink manually will work just as well.
