Linux中设置Redis开机启动的方法

一、CentOS 7.0系统下的设置方法

假设Redis已经安装，版本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 class="lazy" data-src/redis-server /usr/local/bin/

#cp class="lazy" data-src/redis-cli /usr/local/bin/

#vim /etc/init.d/redis

在脚本文件添加 #chkconfig: 2345 80 90

否则会出现 “redis服务不支持chkconfig”的错误提示

#!/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

注册事件，开机启动

#chkconfig redis on

启动服务

#service redis start

查看服务是否启动

#lsof -i:6379

二、Debian 8.0设置方法

步骤与上面类似，不过Debian 用update-rc.d (或insserv)代替chkconfig

脚本文件描述也不一样。

假设Redis已经安装，版本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 class="lazy" data-src/redis-server /usr/local/bin/

#cp class="lazy" data-src/redis-cli /usr/local/bin/

#vim /etc/init.d/redis

在脚本文件添加

### 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

否则会出现 “ insserv: warning: script ‘redis6379′ missing LSB tags and overrides”的错误提示

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

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

注册事件，开机启动

#update-rc.d redisd defaults

启动服务

#service redis start

查看服务是否启动

#lsof -i:6379

开机启动以后，默认的配置文件位置:/etc/redis/6379.conf
