6 # 1k => 1000 bytes
7 # 1kb => 1024 bytes
8 # 1m => 1000000 bytes
9 # 1mb => 1024*1024 bytes
10 # 1g => 1000000000 bytes

109 ################################# REPLICATION #################################
110
111 # Master-Slave replication. Use slaveof to make a Redis instance a copy of
112 # another Redis server. Note that the configuration is local to the slave
113 # so for example it is possible to configure the slave to save the DB with a
114 # different interval, or to listen to another port, and so on.
115 #
116 # slaveof <masterip> <masterport>
117
118 # If the master is password protected (using the "requirepass" configuration
119 # directive below) it is possible to tell the slave to authenticate before
120 # starting the replication synchronization process, otherwise the master will
121 # refuse the slave request.
122 #
123 # masterauth <master-password>
124
125 # When a slave lost the connection with the master, or when the replication
126 # is still in progress, the slave can act in two different ways:
127 #
128 # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will
129 # still reply to client requests, possibly with out of data data, or the
130 # data set may just be empty if this is the first synchronization.
131 #
132 # 2) if slave-serve-stale data is set to 'no' the slave will reply with
133 # an error "SYNC with master in progress" to all the kind of commands
134 # but to INFO and SLAVEOF.
135 #
136 slave-serve-stale-data yes
137
138 # Slaves send PINGs to server in a predefined interval. It's possible to change
139 # this interval with the repl_ping_slave_period option. The default value is 10
140 # seconds.
141 #
142 # repl-ping-slave-period 10
143
144 # The following option sets a timeout for both Bulk transfer I/O timeout and
145 # master data or ping response timeout. The default value is 60 seconds.
146 #
147 # It is important to make sure that this value is greater than the value
148 # specified for repl-ping-slave-period otherwise a timeout will be detected
149 # every time there is low traffic between the master and the slave.
150 #
151 # repl-timeout 60

153 ################################## SECURITY ###################################
154
155 # Require clients to issue AUTH <PASSWORD> before processing any other
156 # commands. This might be useful in environments in which you do not trust
157 # others with access to the host running redis-server.
158 #
159 # This should stay commented out for backward compatibility and because most
160 # people do not need auth (e.g. they run their own servers).
161 #
162 # Warning: since Redis is pretty fast an outside user can try up to
163 # 150k passwords per second against a good box. This means that you should
164 # use a very strong password otherwise it will be very easy to break.

168 # Command renaming.
169 #
170 # It is possilbe to change the name of dangerous commands in a shared
171 # environment. For instance the CONFIG command may be renamed into something
172 # of hard to guess so that it will be still available for internal-use
173 # tools but not available for general clients.
174 #
175 # Example:
176 #
177 # rename-command CONFIG b840fc02d524045429941cc15f59e41cb7be6c52
178 #
179 # It is also possilbe to completely kill a command renaming it into
180 # an empty string:
181 #
182 # rename-command CONFIG ""
183
184 ################################### LIMITS ####################################
185
186 # Set the max number of connected clients at the same time. By default there
187 # is no limit, and it's up to the number of file descriptors the Redis process
188 # is able to open. The special value '0' means no limits.
189 # Once the limit is reached Redis will close all the new connections sending
190 # an error 'max number of clients reached'.
191 #
192 # maxclients 128
193
194 # Don't use more memory than the specified amount of bytes.
195 # When the memory limit is reached Redis will try to remove keys with an
196 # EXPIRE set. It will try to start freeing keys that are going to expire
197 # in little time and preserve keys with a longer time to live.
198 # Redis will also try to remove objects from free lists if possible.
199 #
200 # If all this fails, Redis will start to reply with errors to commands
201 # that will use more memory, like SET, LPUSH, and so on, and will continue
202 # to reply to most read-only commands like GET.
203 #
204 # WARNING: maxmemory can be a good idea mainly if you want to use Redis as a
205 # 'state' server or cache, not as a real DB. When Redis is used as a real
206 # database the memory usage will grow over the weeks, it will be obvious if
207 # it is going to use too much memory in the long run, and you'll have the time
208 # to upgrade. With maxmemory after the limit is reached you'll start to get
209 # errors for write operations, and this may even lead to DB inconsistency.
210 #
211 # maxmemory <bytes>
212
213 # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
214 # is reached? You can select among five behavior:
215 #
216 # volatile-lru -> remove the key with an expire set using an LRU algorithm
217 # allkeys-lru -> remove any key accordingly to the LRU algorithm
218 # volatile-random -> remove a random key with an expire set
219 # allkeys->random -> remove a random key, any key
220 # volatile-ttl -> remove the key with the nearest expire time (minor TTL)
221 # noeviction -> don't expire at all, just return an error on write operations
222 #
223 # Note: with all the kind of policies, Redis will return an error on write
224 # operations, when there are not suitable keys for eviction.
225 #
226 # At the date of writing this commands are: set setnx setex append
227 # incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd
228 # sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby
229 # zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby
230 # getset mset msetnx exec sort
231 #
232 # The default is:
233 #
234 # maxmemory-policy volatile-lru
235
236 # LRU and minimal TTL algorithms are not precise algorithms but approximated
237 # algorithms (in order to save memory), so you can select as well the sample
238 # size to check. For instance for default Redis will check three keys and
239 # pick the one that was used less recently, you can change the sample size
240 # using the following configuration directive.

244 ############################## APPEND ONLY MODE ###############################
245
246 # By default Redis asynchronously dumps the dataset on disk. If you can live
247 # with the idea that the latest records will be lost if something like a crash
248 # happens this is the preferred way to run Redis. If instead you care a lot
249 # about your data and don't want to that a single record can get lost you should
250 # enable the append only mode: when this mode is enabled Redis will append
251 # every write operation received in the file appendonly.aof. This file will
252 # be read on startup in order to rebuild the full dataset in memory.
253 #
254 # Note that you can have both the async dumps and the append only file if you
255 # like (you have to comment the "save" statements above to disable the dumps).
256 # Still if append only mode is enabled Redis will load the data from the
257 # log file at startup ignoring the dump.rdb file.
258 #
259 # IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append
260 # log file in background when it gets too big.
261
262 appendonly no
263
264 # The name of the append only file (default: "appendonly.aof")
265 # appendfilename appendonly.aof
266
267 # The fsync() call tells the Operating System to actually write data on disk
268 # instead to wait for more data in the output buffer. Some OS will really flush
269 # data on disk, some other OS will just try to do it ASAP.
270 #
271 # Redis supports three different modes:
272 #
273 # no: don't fsync, just let the OS flush the data when it wants. Faster.
274 # always: fsync after every write to the append only log . Slow, Safest.
275 # everysec: fsync only if one second passed since the last fsync. Compromise.
276 #
277 # The default is "everysec" that's usually the right compromise between
278 # speed and data safety. It's up to you to understand if you can relax this to
279 # "no" that will will let the operating system flush the output buffer when
280 # it wants, for better performances (but if you can live with the idea of
281 # some data loss consider the default persistence mode that's snapshotting),
282 # or on the contrary, use "always" that's very slow but a bit safer than
283 # everysec.
284 #
285 # If unsure, use "everysec".
286
287 # appendfsync always
288 appendfsync everysec
289 # appendfsync no
290
291 # When the AOF fsync policy is set to always or everysec, and a background
292 # saving process (a background save or AOF log background rewriting) is
293 # performing a lot of I/O against the disk, in some Linux configurations
294 # Redis may block too long on the fsync() call. Note that there is no fix for
295 # this currently, as even performing fsync in a different thread will block
296 # our synchronous write(2) call.
297 #
298 # In order to mitigate this problem it's possible to use the following option
299 # that will prevent fsync() from being called in the main process while a
300 # BGSAVE or BGREWRITEAOF is in progress.
301 #
302 # This means that while another child is saving the durability of Redis is
303 # the same as "appendfsync none", that in pratical terms means that it is
304 # possible to lost up to 30 seconds of log in the worst scenario (with the
305 # default Linux settings).
306 #
307 # If you have latency problems turn this to "yes". Otherwise leave it as
308 # "no" that is the safest pick from the point of view of durability.
309 no-appendfsync-on-rewrite no
310
311 # Automatic rewrite of the append only file.
312 # Redis is able to automatically rewrite the log file implicitly calling
313 # BGREWRITEAOF when the AOF log size will growth by the specified percentage.
314 #
315 # This is how it works: Redis remembers the size of the AOF file after the
316 # latest rewrite (or if no rewrite happened since the restart, the size of
317 # the AOF at startup is used).
318 #
319 # This base size is compared to the current size. If the current size is
320 # bigger than the specified percentage, the rewrite is triggered. Also
321 # you need to specify a minimal size for the AOF file to be rewritten, this
322 # is useful to avoid rewriting the AOF file even if the percentage increase
323 # is reached but it is still pretty small.
324 #
325 # Specify a precentage of zero in order to disable the automatic AOF
326 # rewrite feature.

331 ################################## SLOW LOG ###################################
332
333 # The Redis Slow Log is a system to log queries that exceeded a specified
334 # execution time. The execution time does not include the I/O operations
335 # like talking with the client, sending the reply and so forth,
336 # but just the time needed to actually execute the command (this is the only
337 # stage of command execution where the thread is blocked and can not serve
338 # other requests in the meantime).
339 #
340 # You can configure the slow log with two parameters: one tells Redis
341 # what is the execution time, in microseconds, to exceed in order for the
342 # command to get logged, and the other parameter is the length of the
343 # slow log. When a new command is logged the oldest one is removed from the
344 # queue of logged commands.
345
346 # The following time is expressed in microseconds, so 1000000 is equivalent
347 # to one second. Note that a negative number disables the slow log, while
348 # a value of zero forces the logging of every command.
