We assume redis is running, but we will not find with redis profile redis.conf.
Correct demonstration:
（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)
Seen from here, redis in /etc/rc.d/init.d/redis in
（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
.. ... (omitted subsequent content)
Thus redis.conf here CONF = "/ www / server / redis / redis.conf"
Wrong Demonstration
(1) find / redis.conf (not found)
(2) find / 6379.conf (recommended by friends, but not with eggs)
(3) rpm -ql redis (not OK)
