what have you tried exactly? you can add start scripts in the rcX.d dirs.

Hi Pan64,

I tried to add that script in rcX.d but it dont works. I wanted to run that command script on specific directory (i.e. /home/rails/www.abc.com/" with user RAILS.

which script?

Hi Pan64,

Please find the command script as below:

I have named this script as start.sh and i am running this script in my Documentroot os the site lets say in "/var/www/www.abc.com" directory by switching with the user RAILS.

where did you put that start.sh? how did you set the permissions?

I have kept that scirpt in "/var/www/www.abc.com" directory, and the permission on script is 775.

I am starting this script by following below steps:

1) su - rails
2) cd /var/www/www.abc.com
3) ./start.sh

This way i am manually starting this script.

now i wanted to start this automatically at the boot time.

you wrote: . How did you try it?

I added that script in /etc/init.d/ and then created symlink in rcX.d (i.e S20rubustart) and then reboot server to test it.

probably S99 would be better.
you need to combine all the steps in #7 into one single script I think.
that will look like:

Hi,

I tried solution suggested by you but it didnt worked. Please find the error as below.

I executed this script using root user login.

Please suggest.

Regards,

I can only execute the start.sh script in "/var/www/www.abc.com" directory with rails user. script does not work with any other user and on any other location on server.

Regards,

You can use /etc/rc.local, by adding the sequence of the commands above as follows:

Hi bathory,

I tried your suggested solution but it is not working.

Regards,

What exactly is not working? The command or the startup method (/etc/rc.local)?

Hi,

Command is not working. can you help me to create init script for this same process or command.

Doh, it should work! What it the error you get?
You can also use any of the following 2 approaches:
1. Just put the command "/var/www/www.abc.com/start.sh" in a script and then use su to run it:
2.

Hi Bathory,

I cant see any error message as it is running during the system startup and i dont have the console access of the server. i am accessing my server remotely using SSH.

Let me try the above solution. I get back to you soon.

Hi bathory,

below is the error after applying your suggested solution.
Regards,

I assume the cd into /var/www/www.abc.com is missing.

Hi,

cd is not missing. I have in the script.

can you tell me how can i make a script which do the following steps.

1) su to rail (su - rail).
2) then cd to /var/www/www.abc.com (cd /var/www/www.abc.com).
3) then execute the scirpt ./start.sh

can you tell me how can i make a script. might be that will resolve my issue.

Regards,

Create the script:
Run it as the user rails:
Try it from CLI first to see if it works, or it fails and for what reason

Hi,

below is the error.
I executed the script with rails user.

below is the another result of the command.
Please suggest

Regards,

I'm not familiar with rails, but from the error above, looks like something is missing.
So as suggested, i.e. run "bundle install" and see what you get

Hi bathory,

I am running this script from rails user's home directory, If i run the script command in /var/www/www.abc.com directory it will work as all the bundle components are installed in /var/www/www.abc.com directory. so i must have to run ./start.sh script in the said directory. I cant installed bundle components in the rails user's home directory.

Regards,

This is what the script of post #22 does:
Changes directory to /var/www/www.abc.com
Runs the ./start.sh
Then you, as root use su or sudo to execute the script with the rails user rights

Hi,

But I tried that way same as post:22 which also not works. I tried the same way suggested in post 22.
