Questions[start](server)

I want to give the www-data user the ability to restart bind9 using this command

service bind9 restart

At the moment, they can execute it and it will stop bind9 but not restart it again complaining that permissions will not allow a chmod of the file "named".

can you point me in the direction of what i need to do

Update

Okay so I added the line to the sudoers as requested.

www-data      ALL=NOPASSWD: /etc/init.d/bind9

It still has some issue:

root@LAMPREY:~# su www-data
$ service bind9 restart
 * Stopping domain name service... bind9                                        rndc: error: none:0: open: /etc/bind/rndc.key: permission denied
rndc: could not load rndc configuration
                                                                         [ OK ]
 * Starting domain name service... bind9                                        chmod: changing permissions of `/var/run/named': Operation not permitted
$ exit

I also then tried running another command

/etc/init.d/bind9 restart
 * Stopping domain name service... bind9                                        rndc: error: none:0: open: /etc/bind/rndc.key: permission denied
rndc: could not load rndc configuration
                                                                         [ OK ]
 * Starting domain name service... bind9                                        chmod: changing permissions of `/var/run/named': Operation not permitted
$ exit

with the same result

Is there any way to start a process on a linux computer if I have ftp connection or network connection?

I need to run some bash script only once on first boot (after OS installation) of my CentOS machine This script should run before network service start (because this script will change network configuration) How can I register my script to run before network service start?

I just installed memcached and the memcache pecl extension. Now randomly I cannot get it to start. When I run service memcached start I get this:

Starting memcached: chown: `memcached\r': invalid user
 to switch toe user memcached
 [FAILED]

What is going on? As far as I know, I performed the installation correctly. In fact, it was running fine but must have randomly stopped...? Im running RedHat x86_64 es5.

EDIT: maybe I am doing this wrong. What command do I need to run to check if memcached is running?

Apache2 is not starting my webserver

When I try to restart my webserver apache puts "Resource temporarily unavailable: apr_thread_create: unable to create worker thread" in the error log.

I'm not sure what this means, is my server running out of memory...? Or what's the deal?
