1、设置redis.conf中daemonize为yes,确保守护进程开启。

2、编写开机自启动脚本

vi /etc/init.d/redis

脚本内容如下：

# chkconfig: 2345 10 90  
    # description: Start and Stop redis   
      
    PATH=/usr/local/bin:/sbin:/usr/bin:/bin   
    # redis端口号
    REDISPORT=6379  
    # redis-server所在目录的绝对路径
    EXEC=/usr/apk/redis-2.8.17/redis-server   
    # redis-cli所在目录的绝对路径
    REDIS_CLI=/usr/apk/redis-2.8.17/redis-cli   
     
    PIDFILE=/var/run/redis.pid   
    # redis.conf所在目录的绝对路径
    CONF="/usr/apk/redis-2.8.17/redis.conf"  
    AUTH="nginx"  
     
    case "$1" in   
            start)   
                    if [ -f $PIDFILE ]   
                    then   
                            echo "$PIDFILE exists, process is already running or crashed."  
                    else  
                            echo "Starting Redis server..."  
                            $EXEC $CONF   
                    fi   
                    if [ "$?"="0" ]   
                    then   
                            echo "Redis is running..."  
                    fi   
                    ;;   
            stop)   
                    if [ ! -f $PIDFILE ]   
                    then   
                            echo "$PIDFILE exists, process is not running."  
                    else  
                            PID=$(cat $PIDFILE)   
                            echo "Stopping..."  
                           $REDIS_CLI -p $REDISPORT  SHUTDOWN    
                            sleep 2  
                           while [ -x $PIDFILE ]   
                           do  
                                    echo "Waiting for Redis to shutdown..."  
                                   sleep 1  
                            done   
                            echo "Redis stopped"  
                    fi   
                    ;;   
            restart|force-reload)   
                    ${0} stop   
                    ${0} start   
                    ;;   
            *)   
                   echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2  
                    exit 1  
    esac

3、写完后保存退出VI

4、设置权限

chmod 755 redis

5、启动测试

/etc/init.d/redis start

启动成功会提示如下信息：

Starting Redis server...
    Redis is running...

使用redis-cli测试：

[root@rk ~]# /usr/redisbin/redis-cli
    127.0.0.1:6379> set foo bar
    OK
    127.0.0.1:6379> get foo
    "bar"
    127.0.0.1:6379> exit

6、设置开机自启动

chkconfig redis on

7、关机重启测试
