Web Hosting Talk : Web Hosting Main Forums : VPS Hosting : VPS Tutorials : CentOS 5 Startup script..?

[Zixt]

Hi,

I'm not that good at CentOS and the last time I attempted a startup script I broke my VPS for a good few hours, so I thought this could be a good site to ask for some advice.

I would like to create a startup script that does the following:
- Starts MySQL Service
- Goes to a directory and runs a SH script.

Could anyone help me out with creating a startup script properly?

Thanks.

Hi,

You can edit the /etc/rc.local file.

A default one (mine) looks like this:

----------
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
------------------------------


To start mysql automatically, just add on a new line:

/etc/init.d/mysqld start

OR

/sbin/service mysqld start


To run your custom script ONLY after mysql has started, you can use the && operand, e.g.


/sbin/service mysqld start && /path/to/customshellscript.sh

Here is the proper way to start MySQL automatically on boot with a CentOS 5.x system:

sudo chkconfig mysqld on

If you get a 'command not found' error, your path does not include /sbin (which is where the chkconfig command lives). You will need to either add /sbin to your path, or run this command:

sudo /sbin/chkconfig mysqld on

To verify, run this command:

chkconfig --list

Search for the row named 'mysqld'. Check that the mysql service is on for runlevel 3 (you should see 3n in this row).

As before, if /sbin is not in your path, simply run "/sbin/chkconfig --list".

You can set other services to start (or not to start) on boot. For example, to set Apache to start at boot:

sudo chkconfig httpd on

To automatically run the bash script on boot, vpswing's instructions are correct. Edit /etc/rc.local and add a line at the end pointing towards the script:

/path/to/script.sh

Also, you can use the chkconfig command to set other services to start (or not to start) on boot.

To set Apache to start automatically on boot:

sudo chkconfig httpd on

To set sendmail to not start automatically on boot:

sudo chkconfig sendmail off

Thanks for that! I knew CentOS had something like Ubuntu's update-rc.d command - was too lazy to look it up and used the "rc.local" shortcut.
