how to add a process to the startup

rajesh84210 · 07-24-2009, 02:22 AM

Dear All,
I would like a add a process(mysql in this case) to startup, so that when ever the linux machine boots,mysql also starts automatically(To be precise, iam lookin for something similar to start->run->MSCONFIG->startup in Windows).
i tried chkconfig --add mysql, but i get the following error."error reading information on service mysql: No such file or directory" .Kindly guide me.

Thanks in advance:-)

check whether mysql startup script available or not on this following location /etc/rc.d/init.d/

Hi,

It's always very useful to mention what distro you are using because the commands might differ.

On Debian this is done using update-rc.d if the program exists in /etc/initd.d directory. For example:

Code:

update-rc.d squid3 start 90 2 3 4 5 . stop 03 0 1 6 .

This will create startup and kill links for squid with sequence 90 for startup (after most of the others) on runlevel 2,3,4,5 and 03 for kill (before most of the others) on runlevel 0,1 and 6.

For more info man update-rc.d

Kind regards,

Eric

Making the (very possibly wrong) assumption that chkconfig means a Red Hat family system, try chkconfig mysqld. As mentioned in both of the above posts, the things which chkconfig can operate on are all files under /etc/init.d.

mysql, mysqld just a script name, you can have any name. therefore we will have to pretty sure whether is there any startup script which is related to mysql

you can list all services added on which runlevel
#chkconfig --list

To add a services in runlevels
chkconfig --level 345 squid on
345 means runlevel

It can have any name, but the mysql package of his distro installs it under a specific name which is probably not httpd, shorewall, or anything else. Five bucks says he's on Red Hat, Fedora, or CentOS, where it should be mysqld.

Ya i agree with you naming is very important if not users may be confused with application but what i said above its just a scritname, there are no necessity to be "d"

True; I bolded the d only to make the difference between what the OP tried and what I was suggesting more obvious. Even blind, it's not a bad guess, though; 33 of my 85 available scripts are named with the usual daemon convention.

Thisis the first time iam writing to this forum and am really impressed with the quick responses..

Iam using FC6,

karamarisan · 07-24-2009, 05:14 AM

In that case, up it to ten bucks. Try chkconfig mysqld.

By the way, while you're here - I highly recommend upgrading your Fedora. FC6 is very old by Fedora standards - it's not even called Fedora Core anymore. If nothing else, consider this - should someone discover tomorrow that the right series of port knocks will cause the OpenSSH server to crap itself and provide root shell access to anyone who asks, you won't get the update that fixes that. Ever.

Thanks for the post.. but this is server machine which iam workin on.. i would like to be clarified with the same..

karamarisan · 07-24-2009, 05:26 AM

I'm not sure how being on a 'server' (whatever you mean by that) is relevant, but I realized that I misunderstood your original post. First things first - run chkconfig --list and see if there's a mysqld in there. The package (did you install it through yum or other package management?) should have given you an init script that you just need to enable, if for some reason it isn't already.

rajesh84210 · 07-24-2009, 05:37 AM

Server i meant is that, i cannot update it ,alteast for now.I DO NOT find mysqld process running when i gibe chkconfig --list .. . yes, i did it using Yum..

kirukan · 07-24-2009, 06:11 AM

Hi rajesh you are confusing, anyhow

1. check whether mysql is installed or not
from rpm --> rpm -qa | grep mysql
from source --> you should know the location

2. chkconfig just for add the services on runlevel(you cant check whether process running or not using chkconfig)

3. to check the running process
ps ax | grep mysql

To start with, Iam a newbie to linux and kindly pasdon me if my questions are not very clear.
i didnot start the daemon last time.. but this time, even after startin the daemon, i dont find mysqld daemon when i gibe ckkconfig --list. anyways, on starting mysql manually and again trying chkconfig --list, still i dint see any mysql or mysqld process being listed.(yes, i do find it when i use nmap localhost) .
anyways all i want to know is how to make mysql start automatically when the linux machine starts.
