3# Note on units: when memory size is needed, it is possible to specifiy
4# it in the usual form of 1k 5GB 4M and so forth:
5#
6# 1k => 1000 bytes
7# 1kb => 1024 bytes
8# 1m => 1000000 bytes
9# 1mb => 1024*1024 bytes
10# 1g => 1000000000 bytes
11# 1gb => 1024*1024*1024 bytes
12#
13# units are case insensitive so 1GB 1Gb 1gB are all the same.

15# By default Redis does not run as a daemon. Use 'yes' if you need it.
16# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
17daemonize no
18
19# When running daemonized, Redis writes a pid file in /var/run/redis.pid by
20# default. You can specify a custom pid file location here.
21pidfile redis.pid

23# Accept connections on the specified port, default is 6379
24port 6379

26# If you want you can bind a single interface, if the bind option is not
27# specified all the interfaces will listen for incoming connections.
28#
29# bind 127.0.0.1

31# Close the connection after a client is idle for N seconds (0 to disable)
32timeout 300
33
34# Set server verbosity to 'debug'
35# it can be one of:
36# debug (a lot of information, useful for development/testing)
37# verbose (many rarely useful info, but not a mess like the debug level)
38# notice (moderately verbose, what you want in production probably)
39# warning (only very important / critical messages are logged)
40loglevel verbose
41
42# Specify the log file name. Also 'stdout' can be used to force
43# Redis to log on the standard output. Note that if you use standard
44# output for logging but daemonize, logs will be sent to /dev/null
45logfile stdout
46
47# Set the number of databases. The default database is DB 0, you can select
48# a different one on a per-connection basis using SELECT <dbid> where
49# dbid is a number between 0 and 'databases'-1

91################################# REPLICATION #################################
92
93# Master-Slave replication. Use slaveof to make a Redis instance a copy of
94# another Redis server. Note that the configuration is local to the slave
95# so for example it is possible to configure the slave to save the DB with a
96# different interval, or to listen to another port, and so on.
97#
98# slaveof <masterip> <masterport>
99
100# If the master is password protected (using the "requirepass" configuration
101# directive below) it is possible to tell the slave to authenticate before
102# starting the replication synchronization process, otherwise the master will
103# refuse the slave request.
104#
105# masterauth <master-password>
106
107################################## SECURITY ###################################
108
109# Require clients to issue AUTH <PASSWORD> before processing any other
110# commands. This might be useful in environments in which you do not trust
111# others with access to the host running redis-server.
112#
113# This should stay commented out for backward compatibility and because most
114# people do not need auth (e.g. they run their own servers).
115#
116# Warning: since Redis is pretty fast an outside user can try up to
117# 150k passwords per second against a good box. This means that you should
118# use a very strong password otherwise it will be very easy to break.
119#
120# requirepass foobared
121
122################################### LIMITS ####################################
123
124# Set the max number of connected clients at the same time. By default there
125# is no limit, and it's up to the number of file descriptors the Redis process
126# is able to open. The special value '0' means no limits.
127# Once the limit is reached Redis will close all the new connections sending
128# an error 'max number of clients reached'.
129#
130# maxclients 128
131
132# Don't use more memory than the specified amount of bytes.
133# When the memory limit is reached Redis will try to remove keys with an
134# EXPIRE set. It will try to start freeing keys that are going to expire
135# in little time and preserve keys with a longer time to live.
136# Redis will also try to remove objects from free lists if possible.
137#
138# If all this fails, Redis will start to reply with errors to commands
139# that will use more memory, like SET, LPUSH, and so on, and will continue
140# to reply to most read-only commands like GET.
141#
142# WARNING: maxmemory can be a good idea mainly if you want to use Redis as a
143# 'state' server or cache, not as a real DB. When Redis is used as a real
144# database the memory usage will grow over the weeks, it will be obvious if
145# it is going to use too much memory in the long run, and you'll have the time
146# to upgrade. With maxmemory after the limit is reached you'll start to get
147# errors for write operations, and this may even lead to DB inconsistency.

151############################## APPEND ONLY MODE ###############################
152
153# By default Redis asynchronously dumps the dataset on disk. If you can live
154# with the idea that the latest records will be lost if something like a crash
155# happens this is the preferred way to run Redis. If instead you care a lot
156# about your data and don't want to that a single record can get lost you should
157# enable the append only mode: when this mode is enabled Redis will append
158# every write operation received in the file appendonly.aof. This file will
159# be read on startup in order to rebuild the full dataset in memory.
160#
161# Note that you can have both the async dumps and the append only file if you
162# like (you have to comment the "save" statements above to disable the dumps).
163# Still if append only mode is enabled Redis will load the data from the
164# log file at startup ignoring the dump.rdb file.
165#
166# IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append
167# log file in background when it gets too big.
168
169appendonly no
170
171# The name of the append only file (default: "appendonly.aof")
172# appendfilename appendonly.aof
173
174# The fsync() call tells the Operating System to actually write data on disk
175# instead to wait for more data in the output buffer. Some OS will really flush
176# data on disk, some other OS will just try to do it ASAP.
177#
178# Redis supports three different modes:
179#
180# no: don't fsync, just let the OS flush the data when it wants. Faster.
181# always: fsync after every write to the append only log . Slow, Safest.
182# everysec: fsync only if one second passed since the last fsync. Compromise.
183#
184# The default is "everysec" that's usually the right compromise between
185# speed and data safety. It's up to you to understand if you can relax this to
186# "no" that will will let the operating system flush the output buffer when
187# it wants, for better performances (but if you can live with the idea of
188# some data loss consider the default persistence mode that's snapshotting),
189# or on the contrary, use "always" that's very slow but a bit safer than
190# everysec.
191#
192# If unsure, use "everysec".

198################################ VIRTUAL MEMORY ###############################
199
200# Virtual Memory allows Redis to work with datasets bigger than the actual
201# amount of RAM needed to hold the whole dataset in memory.
202# In order to do so very used keys are taken in memory while the other keys
203# are swapped into a swap file, similarly to what operating systems do
204# with memory pages.
205#
206# To enable VM just set 'vm-enabled' to yes, and set the following three
207# VM parameters accordingly to your needs.
208
209vm-enabled no
210# vm-enabled yes
211
212# This is the path of the Redis swap file. As you can guess, swap files
213# can't be shared by different Redis instances, so make sure to use a swap
214# file for every redis process you are running. Redis will complain if the
215# swap file is already in use.
216#
217# The best kind of storage for the Redis swap file (that's accessed at random)
218# is a Solid State Disk (SSD).
219#
220# *** WARNING *** if you are using a shared hosting the default of putting
221# the swap file under /tmp is not secure. Create a dir with access granted
222# only to Redis user and configure Redis to create the swap file there.

225# vm-max-memory configures the VM to use at max the specified amount of
226# RAM. Everything that deos not fit will be swapped on disk *if* possible, that
227# is, if there is still enough contiguous space in the swap file.
228#
229# With vm-max-memory 0 the system will swap everything it can. Not a good
230# default, just specify the max amount of RAM you can in bytes, but it's
231# better to leave some margin. For instance specify an amount of RAM
232# that's more or less between 60 and 80% of your free RAM.
233vm-max-memory 0
234
235# Redis swap files is split into pages. An object can be saved using multiple
236# contiguous pages, but pages can't be shared between different objects.
237# So if your page is too big, small objects swapped out on disk will waste
238# a lot of space. If you page is too small, there is less space in the swap
239# file (assuming you configured the same number of total swap file pages).
240#
241# If you use a lot of small objects, use a page size of 64 or 32 bytes.
242# If you use a lot of big objects, use a bigger page size.
243# If unsure, use the default :)

246# Number of total memory pages in the swap file.
247# Given that the page table (a bitmap of free/used pages) is taken in memory,
248# every 8 pages on disk will consume 1 byte of RAM.
249#
250# The total swap size is vm-page-size * vm-pages
251#
252# 32M swap should be enough for testing.

255# Max number of VM I/O threads running at the same time.
256# This threads are used to read/write data from/to swap file, since they
257# also encode and decode objects from disk to memory or the reverse, a bigger
258# number of threads can help with big objects even if they can't help with
259# I/O itself as the physical device may not be able to couple with many
260# reads/writes operations at the same time.
261#
262# The special value of 0 turn off threaded I/O and enables the blocking

280# Active rehashing uses 1 millisecond every 100 milliseconds of CPU time in
281# order to help rehashing the main Redis hash table (the one mapping top-level
282# keys to values). The hash table implementation redis uses (see dict.c)
283# performs a lazy rehashing: the more operation you run into an hash table
284# that is rhashing, the more rehashing "steps" are performed, so if the
285# server is idle the rehashing is never complete and some more memory is used
286# by the hash table.
287#
288# The default is to use this millisecond 10 times every second in order to
289# active rehashing the main dictionaries, freeing memory when possible.
290#
291# If unsure:
