Creating script in rc.d
Hi,


I have created customized scripts to start httpd and postgres (For CentOS 6) in /etc/init.d. However for it to work even after reboot, I have to put the script in /etc/rc.d/rc0.d, rc1.d, etc.


Code:
[root@dev3-pdx rc.d]# ls -lrt
total 60
-rwxr-xr-x  1 root root 20199 Oct  4  2017 rc.sysinit
-rwxr-xr-x  1 root root   220 Oct  4  2017 rc.local
-rwxr-xr-x  1 root root  2617 Oct  4  2017 rc
drwxr-xr-x. 2 root root  4096 May 14  2019 rc1.d
drwxr-xr-x. 2 root root  4096 May 14  2019 rc0.d
drwxr-xr-x. 2 root root  4096 May 14  2019 rc6.d
drwxr-xr-x. 2 root root  4096 May 14  2019 rc2.d
drwxr-xr-x. 2 root root  4096 May 14  2019 rc5.d
drwxr-xr-x. 2 root root  4096 May 14  2019 rc4.d
drwxr-xr-x. 2 root root  4096 May 14  2019 rc3.d
drwxr-xr-x. 2 root root  4096 Jan 15 11:49 init.d
[root@dev3-pdx rc.d]#

However, the naming convention for the scripts, for eg, in the directory rc0.d is like this :


Code:
[root@dev3-pdx rc0.d]# ls
K01certmonger  K10cups               K15svnserve        K50kdump       K73winbind           K75quota_nld       K84wpa_supplicant  K88rsyslog      K92iptables      K99rngd

How do I know what number to put for my script? Like K16.....etc.

startpar

STARTPAR(8)						      System Manager's Manual						       STARTPAR(8)

NAME

       startpar - start runlevel scripts in parallel

SYNOPSIS

       startpar [-p par] [-i iorate] [-t timeout] [-T global_timeout] [-a arg] prg1 prg2 ...
       startpar [-p par] [-i iorate] [-t timeout] [-T global_timeout] -M [ boot|start|stop]

DESCRIPTION

       startpar  is  used  to run multiple run-level scripts in parallel.  The degree of parallelism on one CPU can be set with the -p option, the
       default is full parallelism. An argument to all of the scripts can be provided with the -a option.  Processes block  by	pending  I/O  will
       weighting by the factor 800.  To change this factor the option -i can be used to specify an other value.

       The  output  of	each  script is buffered and written when the script exits, so output lines of different scripts won't mix. You can modify
       this behaviour by setting a timeout.

       The timeout set with the -t option is used as buffer timeout. If the output buffer of a script is not empty and the last output was timeout
       seconds ago, startpar will flush the buffer.

       The  -T option timeout works more globally. If no output is printed for more than global_timeout seconds, startpar will flush the buffer of
       the script with the oldest output. Afterwards it will only print output of this script until it is finished.

       The -M option switches startpar into a make(1) like behaviour.  This option takes three different arguments:  boot,  start,  and  stop  for
       reading .depend.boot or .depend.start or .depend.stop respectively in the directory /etc/init.d/.  By scanning the boot and runlevel direc-
       tories in /etc/init.d/ it then executes the appropriate scripts in parallel.

FILES

       /etc/init.d/.depend.boot
       /etc/init.d/.depend.start
       /etc/init.d/.depend.stop
