Redis multiple instance share the same data?

[krish]

I have 4 different redis instance running on multiple port on the same
computer. I am using redis 2.0.0 downloaded on Jul 12, 2010.

I am surprised to see that my data is duplicated to all the instances
which I never expected..

Here is the configuration file


daemonize no

pidfile /home/krish/stacked_db/redis_session.pid

port 6010

bind 127.0.0.1

timeout 300

loglevel notice

logfile /home/krish/stacked_db/redis-session-server.log

databases 16

save 1 1
save 1 10
save 1 10000

rdbcompression yes

dbfilename redis_session.rdb

dir /home/krish/stacked_db


appendonly yes


appendfsync always
# appendfsync everysec
# appendfsync no

glueoutputbuf yes

#shareobjects no
#shareobjectspoolsize 1024

All the database are stored in the same directory. I think, there
could be issues with appendonly log file which could have been read by
all the database. I will verify with different directory and I report
to you..

Just to be clear, when you say "here is the configuration file" do you
mean that all of the instances are using the same configuration file?
Naturally, if you want them to be individual instances, you need to
have a separate configuration file for each, specifying different
dbfilename and appendonly file names.

I may be ignorant where I could have not understood redis
configuration..

As of now, I can confirm that when multiple instances shares the same
directory for the database, the data is duplicated over many redis
instances.
Probably we need to mentioned the appendonly log file name so that we
can different name for appendonly log file.. Anyone knows how to this?

Or Am I missing something?

I am using different configuration files for each redis instance..
only the dbname and port would vary..otherwise configuration is
similar

Hi Mason,

Do you know how to mention the appendonly file name? All I could see
is appendonly yes which enable the appendonly file..

Although a common best practice is to give every Redis instance its
own directory (which I highly recommend), you can use "appendfilename"
(which is documented in the example redis.conf) to configure the AOF
name.
