1. Setup method under CentOS 7.0 system

Assume Redis is installed, version 3.2.4 


#cd redis-3.2.4

#mkdir /etc/redis

#cp redis.conf /etc/redis/6379.conf

#cp utils/redis_init_script /etc/init.d/redis

#chmod a+x /etc/init.d/redis

#cp src/redis-server /usr/local/bin/

#cp src/redis-cli /usr/local/bin/

#vim /etc/init.d/redis

Add in the script file #chkconfig: 2345 80 90

Otherwise, an error will appear that "redis services do not support chkconfig" 


#!/bin/sh
#chkconfig: 2345 80 90
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"

case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed"
else
echo "Starting Redis server..."
$EXEC $CONF
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$CLIEXEC -p $REDISPORT shutdown
while [ -x /proc/${PID} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
fi
;;
*)
echo "Please use start or stop as first argument"
;;
esac

Register the event and boot up 


#chkconfig redis on

Start the service 


#service redis start

See if the service is started 


#lsof -i:6379

2. Debian 8.0 setting method

The steps are similar, but Debian USES them update-rc.d (or insserv) instead of chkconfig

The script file description is also different.

Assume Redis is installed, version 3.2.4 


#cd redis-3.2.4

#mkdir /etc/redis

#cp redis.conf /etc/redis/6379.conf

#cp utils/redis_init_script /etc/init.d/redis

#chmod a+x /etc/init.d/redis

#cp src/redis-server /usr/local/bin/

#cp src/redis-cli /usr/local/bin/

#vim /etc/init.d/redis

Add in the script file 


### BEGIN INIT INFO
# Provides:   redis6379
# Required-Start: $local_fs $network
# Required-Stop:  $local_fs
# Default-Start:  2 3 4 5
# Default-Stop:  0 1 6
# Short-Description: redis6379
# Description:  penavico redis 6379
### END INIT INFO

Otherwise it will happen “ insserv: warning: script ‘redis6379′ missing LSB tags and overrides” Error prompt 


#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

### END INIT INFO

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"

case "$1" in
 start)
  if [ -f $PIDFILE ]
  then
    echo "$PIDFILE exists, process is already running or crashed"
  else
    echo "Starting Redis server..."
    $EXEC $CONF
  fi
  ;;
 stop)
  if [ ! -f $PIDFILE ]
  then
    echo "$PIDFILE does not exist, process is not running"
  else
    PID=$(cat $PIDFILE)
    echo "Stopping ..."
    $CLIEXEC -p $REDISPORT shutdown
    while [ -x /proc/${PID} ]
    do
     echo "Waiting for Redis to shutdown ..."
     sleep 1
    done
    echo "Redis stopped"
  fi
  ;;
 *)
  echo "Please use start or stop as first argument"
  ;;
esac

Register the event and boot up 


#update-rc.d redisd defaults

Start the service 


#service redis start

See if the service is started 


#!/bin/sh
#chkconfig: 2345 80 90
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"

case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed"
else
echo "Starting Redis server..."
$EXEC $CONF
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$CLIEXEC -p $REDISPORT shutdown
while [ -x /proc/${PID} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
fi
;;
*)
echo "Please use start or stop as first argument"
;;
esac
0

After startup, the default configuration file location: / etc/redis / 6379. conf
