To autostart services in Centos or Redhat OS, you can use builtin chkconfig utility. It is located in /sbin directory. If you are a regular user (non-root), then /sbin may not be in your path. Therefore, you may have to use the full path to access the chkconfig utility.
To auto start a new service:
- Find out the name of service’s script from /etc/init.d/ directory e.g. mysqld or httpd
- Add it to chkconfig
sudo /sbin/chkconfig --add mysqld
- Make sure it is in the chkconfig.
sudo /sbin/chkconfig --list mysqld
- Set it to autostart
sudo /sbin/chkconfig mysqld on
To stop a service from auto starting on boot
- sudo /sbin/chkconfig mysqld off
