how create a service for installed STUNNEL on CentOS 5.10

SilverLight picture SilverLight · May 8, 2014 · Viewed 14.3k times · Source

i have installed stunnel in my centos machine like below :

yum install stunnel -y

openssl genrsa -out privkey.pem 2048
openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095
cat privkey.pem cacert.pem >> /etc/stunnel/stunnel.pem
chmod 600 /etc/stunnel/stunnel.pem
chown nobody.nobody /var/run/stunnel

nano -K /etc/stunnel/stunnel.conf

cert = /etc/stunnel/stunnel.pem
chroot = /var/run/stunnel/
pid = /stunnel.pid
setuid = nobody
setgid = nobody
output = stunnel.log

[squid]
# Ensure the ‘connect’ line matches your squid port. Default is 3128
accept = 8088
connect = 127.0.0.1:1945


my problem is after stunnel installation there is no service for installed stunnel.
so i wrote this :


nano -K /etc/init.d/stunnel

#!/bin/bash
#       /etc/rc.d/init.d/stunnel
#
# Starts the stunnel daemon
#
# chkconfig: 345 70 30
# description: Stunnel Server is a ...
# processname: stunnel
# config: /etc/stunnel/stunnel.conf

# Source function library.
. /etc/init.d/functions

test -x /usr/sbin/stunnel || exit 0
RETVAL=0
#
#       See how we were called.
#
prog="stunnel"
start() {
    # Check if stunnel is already running
    if [ ! -f /var/lock/subsys/stunnel ]; 
    then
    echo -n $"Starting $prog: "
    daemon /usr/sbin/stunnel
    RETVAL=$?
    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/stunnel
    echo
    fi
    return $RETVAL
}
stop() {
    echo -n $"Stopping $prog: "
    killproc /usr/sbin/stunnel
    RETVAL=$?
    [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/stunnel
    echo
    return $RETVAL
}
restart() {
    stop
    start
}
reload() {
    restart
}
status() {
    status /usr/sbin/stunnel
}
case "$1" in
start)
    start
    ;;
stop)
    stop
    ;;
reload|restart)
    restart
    ;;
status)
    status
    ;;
*)
    echo $"Usage: $0 {start|stop|restart|reload|status}"
    exit 1
esac
exit $?
exit $RETVAL

chmod +x /etc/init.d/stunnel

chkconfig --add stunnel


the start command for the written service works fine : service stunnel start : OK.

but i have error during stop command : service stunnel stop : FAILED

and i have error during status command : service stunnel status :
/sbin/service: line 66: 7456 Segmentation fault env -i LANG="$LANG" PATH="$PATH" TERM="$TERM" "${SERVICEDIR}/${SERVICE}" ${OPTIONS}

what did i do wrong and how can i fix the problem?
is there a better way for getting that service?

thanks in advance
