daemonize no
# 修改成：
daemonize yes

# Specify the log file name. Also the empty string can be used to force

You should check your redis.conf file to see the permissions in dir and dbfilename. 
If the file named in the dbfilename which is located in the path specified in the 
dir path exists and the permission is also right. then the problem should be fixed.

Hope this will help someone.

P.S.

To find the redis.conf file location, you can use the #ps ax | grep redis to check. 
Usually it will be passed to the redis-server as input file.

For the dir permissions:it should be 755, for the dbfilename, it should be 644

Sometimes you also need to use top command to check whether the user:group of 
the redis-server and the owner of dir are consistent. 
i.e. The redis-server is running by redis:redis, but the dir is under root:root. 
In this case, you need to chown redis:redis -R dir.
