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=/var/run/redis_{REDISPORT}.pid   </span></span></li><li class="alt"><span>CONF=<span class="string">"/etc/redis/{REDISPORT}.conf”

case “1"</span><span> </span><span class="keyword">in</span><span>   </span></span></li><li class=""><span>    start)   </span></li><li class="alt"><span>        <span class="keyword">if</span><span> [ -f PIDFILE ]
then
echo ”PIDFILE exists, process is already running or crashed"</span><span>   </span></span></li><li class=""><span>        <span class="keyword">else</span><span>   </span></span></li><li class="alt"><span>                echo <span class="string">"Starting Redis server..."</span><span>   </span></span></li><li class=""><span>                EXEC CONF &   </span></li><li class="alt"><span>        fi   </span></li><li class=""><span>        ;;   </span></li><li class="alt"><span>    stop)   </span></li><li class=""><span>        <span class="keyword">if</span><span> [ ! -f PIDFILE ]
then
echo ”PIDFILE does not exist, process is not running"</span><span>   </span></span></li><li class="alt"><span>        <span class="keyword">else</span><span>   </span></span></li><li class=""><span>                PID=(cat PIDFILE)   </span></li><li class="alt"><span>                echo <span class="string">"Stopping ..."</span><span>   </span></span></li><li class=""><span>                CLIEXEC -p REDISPORT shutdown   </span></li><li class="alt"><span>                <span class="keyword">while</span><span> [ -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}.conf"

case "1"instart)if[−fPIDFILE ]
then
echo "PIDFILEexists,processisalreadyrunningorcrashed"elseecho"StartingRedisserver..."EXEC CONF &
fi
;;
stop)
if [ ! -fPIDFILE ]
then
echo "PIDFILEdoesnotexist,processisnotrunning"elsePID=(cat PIDFILE)echo"Stopping..."CLIEXEC -p REDISPORTshutdownwhile[−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。
