I've set up apache, mysql and php on my AWS EC2 instance, but how could it be done that these services are starting when the EC2 is starting? I've found the
chkconfig -a mysql command but this just gives an error like
option -a not found.
I read the chkconfig man page for you and it says
chkconfig [--level <levels>] [--type <type>]<name> <on|off|reset|resetpriorities>
chkconfig --level 3 mysqld on
would start the mysql daemon at runlevel 3. Similarly
chkconfig --level 3 httpd on
would start Apache in runlevel 3.
