Support request: Don't understand redis port  #170

Hello,

I don't understand the github instalation part of the misp-dashboard.
Before the installation they say to "Update the configuration file config.cfg so that it matches your system "
Then below there is the fields that you may change in this file:

    RedisGlobal -> host
    RedisGlobal -> port
    RedisGlobal -> zmq_url
    RedisGlobal -> misp_web_url
    RedisMap -> pathMaxMindDB

In the step just after this one above( Starting the system) they say "Be sure to have running redis server
eg. redis-server --port 6250"

When i look at the ps -aux | grep "redis-server" i've already have a redis serverrunning at port 6379:

redis        779  0.2  0.0  78452 11324 ?        Ssl  17:30   0:03 /usr/bin/redis-server 127.0.0.1:6379

But when i put this port in config.cfg, and when i do ./start_all.sh a new redis server processes is created listening on port 6250 while i've put the 6379 port
