On a centos 6 derivative (Amazon Linux), I have an init.d script ecrinit that is meant to enable/disable some services at system startup (based on contents of a properties file on disk):
if [[ "$nodeType" == "foo" ]]; then #turn off mysql, turn on proftpd service mysqld stop chkconfig mysqld off # prevent lower-pri mysqld service from chkconfig proftpd reset # re-enables at run levels 2-4 fi
Since start pri of ecrinit is 60 and of proftpd is 88, I expected the latter to be started by the boot process, since calling chkconfig reset above ensured that appropriate files exist in /etc/rc3.d (confirmed).
But that does not seem to be the case, as 'start' is never called on proftpd (I added a log statement to latter script's body to confirm) if I issue 'chkconfig proftpd off' before doing 'init 6'. In other words, it seems that the boot process checks contents of /etc/rc3.d before ecrinit is executed (and does not detect new files in same dir during boot process)...
Is that the expected behavior? If so, how can i control which services should be enabled on a given startup (and avoid manually starting them to preserve priority order)?
