我们假设redis正在运行，但是我们找不带redis的配置文件redis.conf.
正确的示范：
（1）systemctl status redis
● redis.service - LSB: starts Redis
Loaded: loaded (/etc/rc.d/init.d/redis; bad; vendor preset: disabled)
Active: inactive (dead)
Docs: man:systemd-sysv-generator(8)
由此处可见，redis在/etc/rc.d/init.d/redis中
（2）cat /etc/rc.d/init.d/redis
#!/bin/sh
# chkconfig: 2345 56 26
# description: Redis Service
### BEGIN INIT INFO
# Provides: Redis
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts Redis
# Description: starts the BT-Web
### END INIT INFO
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
CONF="/www/server/redis/redis.conf"
REDISPORT=$(cat $CONF |grep port|grep -v '#'|awk '{print $2}')
REDISPASS=$(cat $CONF |grep requirepass|grep -v '#'|awk '{print $2}')
if [ "$REDISPASS" != "" ];then
REDISPASS=" -a $REDISPASS"
fi
if [ -f /www/server/redis/start.pl ];then
STARPORT=$(cat /www/server/redis/start.pl)
else
STARPORT=6379
fi
EXEC=/www/server/redis/src/redis-server
CLIEXEC="/www/server/redis/src/redis-cli -p $STARPORT$REDISPASS"
PIDFILE=/var/run/redis_6379.pid
.. ... (后续内容省略)
由此可见 redis.conf 在这儿 CONF="/www/server/redis/redis.conf"
错误的示范
（1）find / redis.conf (找不到)
（2）find / 6379.conf （某位网友的建议，然而没卵用）
（3）rpm -ql redis （也不行）
