Failed opening .rdb for saving: Permission denied

[David Montgomery]

Hi,

Why?  Why cant rdb save?  My /dir/redis dir is owned by root and has rwx permissions.  Redis is run as root.

Thanks

Under which user does Redis run?
What are the _exact_ permissions for that directory? It might be a good
idea to make the user Redis runs under the owner.

I tried changing owner to redis in /data/redis to no avail.  Is this a known issue with redis?

[Jan-Erik Rediger]

It's a known issue if the permissions are incorrect.
Again:
* Is Redis running under the correct user?
* Is it actually using the right config? So is it trying to save to the directory you modified?

What do the permissions have to be running as root?

Below is the config

# The filename where to dump the DB
dbfilename dump.rdb

# The working directory.
#
# The DB will be written inside this directory, with the filename specified
# above using the 'dbfilename' configuration directive.
#
# The Append Only File will also be created inside this directory.
#
# Note that you must specify a directory here, not a file name.
dir /data/redis

change directory permission for writing :)

David Montgomery:

Redis is run as root.

Have you confirmed this with a ps command?

Is /data/redis on a shared filesystem like NFS or Samba/CIFS?  NFS servers in particular will often behave in confusing ways when an NFS client machine tries to use the root account to write.
