CentOS7 下redis不能開機啟動，求解？

Question

我的/etc/init.d/redis 腳本可以正常啟動或停止redis服務

service redis start
service redis stop
service redis restart

我也設定了/etc/init.d/redis權限為755
也設定了開機啟動chkconfig redis on

chkconfig --list如下：

redis              0:关    1:关    2:开    3:开    4:开    5:开    6:关

請問為什麼不能開機啟動呢？求解決辦法

附：/etc/init.d/redis程式碼如下：

# chkconfig: 2345 10 90
#!/bin/sh
#
# 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_${REDISPORT}.pid
CONF="/usr/local/redis/redis.conf"
AUTH="111111"
# CONF="/etc/redis/${REDISPORT}.conf"

case "" 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 -a $AUTH shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    restart|force-reload)
        rrreee stop
        rrreee start
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

Answer 1

自己參考php-fpm提供的啟動文件，加了這麼句話搞定了，什麼原理不知道

### BEGIN INIT INFO
# Provides:          redis
# Required-Start:    $remote_fs $network
# Required-Stop:     $remote_fs $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts redis
# Description:       starts the redis FastCGI Process Manager daemon
### END INIT INFO

看看日誌，有可能是報錯了

要是不行，你就在/etc/rc.local里面的exit之前加一句：sudo service redis-server start。
