redisプロファイル
        :redis.pid    

次は私のプロファイルです.
# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize yes

# When running daemonized, Redis writes a pid file in /var/run/redis.pid by
# default. You can specify a custom pid file location here.

var/runの実行権限
lrwxrwxrwx  1 root root        4 Feb 24 06:57 run -> /run

そして私はsudo touch redisを使います.pid
root@ubuntu:/home/fuhui/redis-2.8.19/utils# pwd
/home/fuhui/redis-2.8.19/utils

root@ubuntu:/home/fuhui/redis-2.8.19/utils# sh redis_init_script stop
/var/run/redis_6379.pid does not exist, process is not running

権限の問題かどうか分からないので、o権限を変更します
fuhui@ubuntu:/var/run$ sudo chmod o+wx redis.pid
-rw-r--rwx 1 root       root          0 Jun 22 08:39 redis.pid

サービスが再起動されていないのではないでしょうか.
fuhui@ubuntu:/var/run$ ps -ef | grep 'redis'

再起動してみろpidにpid番号が入っています

shellファイルの下を修正するのは元のファイルで、私たちがしなければならないのは実はとても簡単で、経路を実際に保存することに修正するだけでいいです

        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

次のように変更します.
root@ubuntu:/home/fuhui/redis-2.8.19/utils# cp redis_init_script ../redis_script

procの下にpidがあるかどうか見てみましょう
fuhui@ubuntu:/proc$ cd /proc/
fuhui@ubuntu:/proc$ ls -lh | grep 2912
dr-xr-xr-x  9 root       root          0 Jun 22 08:47 2912
