Windows下Redis的安裝使用教程

# Redis configuration file example 
 
# By default Redis does not run as a daemon. Use 'yes' if you need it. 
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized. 
# 是否以后臺進(jìn)程的形式運(yùn)行，默認(rèn)為no 
daemonize no 
 
# When run as a daemon, Redis write a pid file in /var/run/redis.pid by default. 
# You can specify a custom pid file location here. 
# 如果指定以后臺形式執(zhí)行，則需要指定一個pid文件 
pidfile /var/run/redis.pid 
 
# Accept connections on the specified port, default is 6379 
#監(jiān)聽端口號 
port 6379 
 
# If you want you can bind a single interface, if the bind option is not 
# specified all the interfaces will listen for connections. 
# 綁定主機(jī)IP 
# bind 127.0.0.1 
 
# Close the connection after a client is idle for N seconds (0 to disable) 
# 客戶端空閑超時時間，設(shè)置為0，則沒有超時。過了空閑時間，則會將客戶端的連接關(guān)閉 
timeout 300 
 
# Set server verbosity to 'debug' 
# it can be one of: 
# debug (a lot of information, useful for development/testing) 
# notice (moderately verbose, what you want in production probably) 
# warning (only very important / critical messages are logged) 
# 日志記錄等級 
loglevel debug 
 
# Specify the log file name. Also 'stdout' can be used to force 
# the demon to log on the standard output. Note that if you use standard 
# output for logging but daemonize, logs will be sent to /dev/null 
# 日志記錄方式 
logfile stdout 
 
# Set the number of databases. The default database is DB 0, you can select 
# a different one on a per-connection basis using SELECT dbid> where 
# dbid is a number between 0 and 'databases'-1 
# 可用數(shù)據(jù)庫數(shù)目 
databases 16 
 
################################ SNAPSHOTTING ################################# 
# 
# Save the DB on disk: 
# 
# save seconds> changes> 
# 
# Will save the DB if both the given number of seconds and the given 
# number of write operations against the DB occurred. 
# 
# In the example below the behaviour will be to save: 
# after 900 sec (15 min) if at least 1 key changed 
# after 300 sec (5 min) if at least 10 keys changed 
# after 60 sec if at least 10000 keys changed 
save 900 1 
save 300 10 
save 60 10000 
 
# Compress string objects using LZF when dump .rdb databases? 
# For default that's set to 'yes' as it's almost always a win. 
# If you want to save some CPU in the saving child set it to 'no' but 
# the dataset will likely be bigger if you have compressible values or keys. 
# 存儲到本地數(shù)據(jù)庫時，是否需要壓縮數(shù)據(jù) 
rdbcompression yes 
 
# The filename where to dump the DB 
#本地數(shù)據(jù)名稱

# For default save/load DB in/from the working directory 
# Note that you must specify a directory not a file name. 
# 本地數(shù)據(jù)庫存放路徑 
dir ./ 
 
################################# REPLICATION ################################# 
 
# Master-Slave replication. 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. 
# 當(dāng)該服務(wù)為從服務(wù)時，設(shè)置主服務(wù)的ip地址和端口號 
# 
# slaveof masterip> masterport> 
 
# If the master is password protected (using the "requirepass" configuration 
# directive below) it is possible to tell the slave to authenticate before 
# starting the replication synchronization process, otherwise the master will 
# refuse the slave request. 
# 當(dāng)該服務(wù)為從服務(wù)時，設(shè)置主服務(wù)的連接密碼 
# 
# masterauth master-password> 
 
################################## SECURITY ################################### 
 
# Require clients to issue AUTH PASSWORD> 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). 
# 連接密碼 
# 
# 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'. 
# 最大客戶端連接數(shù)，默認(rèn)不設(shè)置 
# 
# 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. 
# 設(shè)置最大內(nèi)存，達(dá)到最大內(nèi)存設(shè)置后，Redis線嘗試清楚已到期或即將到期的key,當(dāng)此方法處理后，達(dá)到最大內(nèi)存設(shè)置，將不能在進(jìn)行寫入操作。

############################## APPEND ONLY MODE ############################### 
 
# By default Redis asynchronously dumps the dataset on disk. If you can live 
# with the idea that the latest records will be lost if something like a crash 
# happens this is the preferred way to run Redis. If instead you care a lot 
# about your data and don't want to that a single record can get lost you should 
# enable the append only mode: when this mode is enabled Redis will append 
# every write operation received in the file appendonly.log. This file will 
# be read on startup in order to rebuild the full dataset in memory. 
# 
# Note that you can have both the async dumps and the append only file if you 
# like (you have to comment the "save" statements above to disable the dumps). 
# Still if append only mode is enabled Redis will load the data from the 
# log file at startup ignoring the dump.rdb file. 
# 
# The name of the append only file is "appendonly.log" 
# 
# IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append 
# log file in background when it gets too big. 
# 設(shè)置Redis服務(wù)器在每次操作完成后，是否更新日志操作，如果關(guān)閉，可能會在斷電時導(dǎo)致一段時間內(nèi)的數(shù)據(jù)丟失， 
# 因為Redis本身同步數(shù)據(jù)文件是按照上面的save條件來同步的，所以有的數(shù)據(jù)會在一段時間內(nèi)存儲于內(nèi)存中。

# The fsync() call tells the Operating System to actually write data on disk 
# instead to wait for more data in the output buffer. Some OS will really flush 
# data on disk, some other OS will just try to do it ASAP. 
# 
# Redis supports three different modes: 
# 
# no: don't fsync, just let the OS flush the data when it wants. Faster. 
# always: fsync after every write to the append only log . Slow, Safest. 
# everysec: fsync only if one second passed since the last fsync. Compromise. 
# 
# The default is "always" that's the safer of the options. It's up to you to 
# understand if you can relax this to "everysec" that will fsync every second 
# or to "no" that will let the operating system flush the output buffer when 
# it want, for better performances (but if you can live with the idea of 
# some data loss consider the default persistence mode that's snapshotting). 
# 更新日志條件,有三個可選值: 
 
appendfsync always 
# appendfsync everysec 
# appendfsync no 
 
############################### 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
