I am trying to write an init script for a shell script and want to know how I can create a PID file for script. I have noticed that in SuSE, there is a function called
startproc that accepts a
-p option to create a PID file. I have determined that the Redhat/Fedora equivalent to startproc is
exec - but this doesn't have a
-p option.
This is the SuSE init script that I found as an example to run my shell script:
Code:
#!/bin/bash
#
#
#
# /etc/init.d/syslog2mysql
#
# Comments to support chkconfig on RedHat Linux
# chkconfig: 235 65 35
# description: A very fast and reliable SQL database engine.
### BEGIN INIT INFO
# Provides: syslog2mysql
# Required-Start: $local_fs $network syslog mysql
# Should-Start: syslog mysql
# Required-Stop: $local_fs $network syslog mysql
# Default-Start: 2 3 5
# Default-Stop: 0 1 6
# Short-Description: Start and Stop Syslog2MySQL
# Description: Script to push Syslog data to MySql data base
### END INIT INFO
syslog2mysql_pid="/var/run/syslog2mysql.pid"
syslog2mysql="/var/www/html/phpSyslog-ng/scripts/syslog2mysql.sh"
. /etc/rc.status
rc_reset
case "$1" in
start)
test -s ${syslog2mysql_pid} && {
killproc -p ${syslog2mysql_pid} ${syslog2mysql}
echo -n "Re-"
}
echo -n "Starting syslog2mysql services"
startproc -p ${syslog2mysql_pid} ${syslog2mysql} $params
ps -C syslog2mysql.sh -o pid= > ${syslog2mysql_pid}
rc_status -v
;;
stop)
echo -n "Shutting down syslog2mysql services"
killproc -p ${syslog2mysql_pid} -TERM ${syslog2mysql} ; rc_status -v
rm -f ${syslog2mysql_pid}
;;
status)
echo -n "Checking for service syslog2mysql:"
checkproc -p ${syslog2mysql_pid} ${syslog2mysql} ; rc_status -v
;;
*)
echo "Usage: $0 {start|stop|status}"
exit 1
;;
esac
rc_exit
This is the section I am trying to convert from SuSE to Fedora:
Code:
startproc -p ${syslog2mysql_pid} ${syslog2mysql} $params
ps -C syslog2mysql.sh -o pid= > ${syslog2mysql_pid}
Another side issue - I am looking for any mapping of functions in SuSE to Fedora that can help me with my init scripts. Example: in Fedora what is the equivalent funtion for rc_status in SuSE.
