Use slaveof to make a Redis instance a copy of # another Redis server. Note that the configuration is local to the slave # so for example it is possible to configure the slave to save the DB with a # different interval, or to listen to another port, and so on. # slaveof ################################## SECURITY ################################### # Require clients to issue AUTH before processing any other # commands. This might be useful in environments in which you do not trust # others with access to the host running redis-server. # # This should stay commented out for backward compatibility and because most # people do not need auth (e.g. they run their own servers). # requirepass foobared ################################### LIMITS #################################### # Set the max number of connected clients at the same time. By default there # is no limit, and it's up to the number of file descriptors the Redis process # is able to open. The special value '0' means no limts. # Once the limit is reached Redis will close all the new connections sending # an error 'max number of clients reached'. # maxclients 128 # Don't use more memory than the specified amount of bytes. # When the memory limit is reached Redis will try to remove keys with an # EXPIRE set. It will try to start freeing keys that are going to expire # in little time and preserve keys with a longer time to live. # Redis will also try to remove objects from free lists if possible. # # If all this fails, Redis will start to reply with errors to commands # that will use more memory, like SET, LPUSH, and so on, and will continue # to reply to most read-only commands like GET. # # WARNING: maxmemory can be a good idea mainly if you want to use Redis as a # 'state' server or cache, not as a real DB. When Redis is used as a real # database the memory usage will grow over the weeks, it will be obvious if # it is going to use too much memory in the long run, and you'll have the time # to upgrade. With maxmemory after the limit is reached you'll start to get # errors for write operations, and this may even lead to DB inconsistency. # maxmemory ############################### ADVANCED CONFIG ############################### # Glue small output buffers together in order to send small replies in a # single TCP packet. Uses a bit more CPU but most of the times it is a win # in terms of number of queries per second. Use 'yes' if unsure. glueoutputbuf yes # Use object sharing. Can save a lot of memory if you have many common # string in your dataset, but performs lookups against the shared objects # pool so it uses more CPU and can be a bit slower. Usually it's a good # idea. # # When object sharing is enabled (shareobjects yes) you can use # shareobjectspoolsize to control the size of the pool used in order to try # object sharing. A bigger pool size will lead to better sharing capabilities. # In general you want this value to be at least the double of the number of # very common strings you have in your dataset. # # WARNING: object sharing is experimental, don't enable this feature # in production before of Redis 1.0-stable. Still please try this feature in # your development environment so that we can test it better. shareobjects no shareobjectspoolsize 1024 EOS class Redis
