在《Redis探索之旅（3）- 在Windows下将Redis注册成本地服务》我们讲述了如何在Windows下的操作方法，在这篇文章中，我们看看在Linux下如何操作。

我们按照下面的步骤一步一步来。

（1）将Redis目录下的初始化脚本拷贝到/etc/rc.d/init.d目录；

redis的初始化脚本目录为：/usr/local/src/redis/utils/redis_init_script

将这个目录拷贝到目标目录，同时将文件夹名称进行修改：

[javascript] view plain copy

print ?

cp /usr/local/src/redis/utils/redis_init_script /etc/rc.d/init.d/redis

cp /usr/local/src/redis/utils/redis_init_script /etc/rc.d/init.d/redis

然后添加注册服务，如下所示：

[javascript] view plain copy

print ?

chkconfig –add redis

chkconfig --add redis

执行后，可能你会遇到下面的错误：

[javascript] view plain copy

print ?

redis服务不支持chkconfig

redis服务不支持chkconfig

因此，我们还需要对初始化脚本做一些修改。

（2）修改脚本

我们首先打开redis脚本，修改后内容如下：

[javascript] view plain copy

print ?

#!/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/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
PIDFILE=//run/redis_ ${REDISPORT}.pid   </li><li class="alt">CONF="/etc/redis/$ {REDISPORT}.conf”
case “ $1" in   </li><li class="">    start)   </li><li class="alt">        if [ -f $ PIDFILE ]
then
echo ” $PIDFILE exists, process is already running or crashed"   </li><li class="">        else   </li><li class="alt">                echo "Starting Redis server..."   </li><li class="">                $ EXEC $CONF &   </li><li class="alt">        fi   </li><li class="">        ;;   </li><li class="alt">    stop)   </li><li class="">        if [ ! -f $ PIDFILE ]
then
echo ” $PIDFILE does not exist, process is not running"   </li><li class="alt">        else   </li><li class="">                PID=$ (cat $PIDFILE)   </li><li class="alt">                echo "Stopping ..."   </li><li class="">                $ CLIEXEC -p $REDISPORT shutdown   </li><li class="alt">                while [ -x /proc/$ {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

#!/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/redis/bin/redis-server CLIEXEC=/usr/local/redis/bin/redis-cli PIDFILE=/var/run/redis_

REDISPORT.pidCONF="/etc/redis/ ${REDISPORT}.pid CONF="/etc/redis/$ {REDISPORT}.conf" case "

1"instart)if[−f $1" in start) if [ -f$ PIDFILE ] then echo "

PIDFILEexists,processisalreadyrunningorcrashed"elseecho"StartingRedisserver..." $PIDFILE exists, process is already running or crashed" else echo "Starting Redis server..."$ EXEC

CONF &
        fi
        ;;
    stop)
        if [ ! -f $CONF & fi ;; stop) if [ ! -f$ PIDFILE ] then echo "

PIDFILEdoesnotexist,processisnotrunning"elsePID= $PIDFILE does not exist, process is not running" else PID=$ (cat

PIDFILE)echo"Stopping..." $PIDFILE) echo "Stopping ..."$ CLIEXEC -p

REDISPORTshutdownwhile[−x/proc/ $REDISPORT shutdown while [ -x /proc/$ {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
脚本的修改地方主要涉及以下几个地方：

（a）第二行增加如下内容

[javascript] view plain copy

print ?

#chkconfig: 2345 80 90

#chkconfig: 2345 80 90

（b）原脚本EXEC和CLIEXEC的值因为目录不同而有所修改

[javascript] view plain copy

print ?

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

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

（c）redis启动的命令改为以后台方式启动

[javascript] view plain copy

print ?

$EXEC $ CONF &

$EXEC $CONF &

（d）将redis配置文件拷贝到/etc/redis/端口ID.conf，如下所示：

[javascript] view plain copy

print ?

mkdir /etc/redis
cp /usr/local/src/redis/redis.conf /etc/redis/6379.conf

mkdir /etc/redis    
cp /usr/local/src/redis/redis.conf /etc/redis/6379.conf

默认情况下，redis启动时不启用鉴权认证，如果有需要，可以在配置文件中进行设置requirepass参数。

通过上面的脚本修改后，我们可以再次使用下面的命令进行注册服务：

[javascript] view plain copy

print ?

chkconfig –add redis

chkconfig --add redis

注册成功后，然后就是启动服务了，如下所示：

[javascript] view plain copy

print ?

service redis start

service redis start

至此，单实例redis服务便启动起来了。
