Installation and use of Redis under Windows

Recently learned data caching technology, search on the internet, found that Java cache technology is more popular with Redis and memcached, for the purpose of learning, here do not compare their.

This blog focuses on the installation and use of a redis in cache technology.

One, download Redis for Windows

Search Redis fow windows on your network to download the Redis compact package. Unpack the package.

You will find 32-bit and 64-bit versions of the package, as appropriate, using the corresponding compression package.

Second, decompression

I'm using Redisbin_x64.zip's compressed package and unzip it into the Redis folder.

After unpacking, you will find only a few. exe files. Here, Redis is a good general.

Third, the configuration

Create a new Conf folder under Redis and make a redis.conf text file. Copy the contents to the configuration file.

# Redis configuration file example# By default Redis does not run as a daemon.

This might is useful in environments in which you does not trust# others with access to the host running redis-server.## Thi s should stay commented out for backward compatibility and because most# people does not need auth (e.g. they run their own servers). # Connection Password # # 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# are able to open. The special value ' 0 ' means no limts.# Once the limit is reached Redis would close all the new connections sending# an error ' max number of clients reached '. # Maximum client connections, default not set # # maxclients 128# Don ' t use more Memory than the specified amount of bytes.# when the memory limit is reached Redis would try to remove keys with an# Expir E set. It'll try to start freeing keys this is going to expire# in little time and preserve keys with a longer time to live.# Redis would also try to remove objects from free lists if possible.## if all this fails, Redis would start to reply with err ORS to commands# that would use more memory, like SET, Lpush, and so on, and would continue# to reply to the most read-only comm ANDs like get.## Warning:maxmemory can is a good idea mainly if you want the use of Redis as a# ' state ' server or cache, not As a real DB. When Redis is used as a real# database the memory usage would grow over the weeks, it'll be obvious if# it's going to us E Too much memory in the long run, and you'll have the time# to upgrade. With MaxMemory after the limit was reached you ' ll START to get# errors for write operations, and this may even leads to DB inconsistency.# set maximum memory, after reaching maximum memory setting, Redis Line tries to understand the expired or expiring K EY, when this method is processed, the maximum memory setting is reached and the write operation cannot be performed. # # MaxMemory <bytes>############################## APPEND only MODE ################################ by default Redis asynchronously dumps the dataset on disk. If you can live# with the idea that the latest records would be be lost if something like a crash# happens this is the Preferr Ed to run Redis. If instead a lot# about your data and don ' t want to that a single record can get lost you should# enable the AppE nd only mode:when This mode is enabled Redis would append# every write operation received in the file Appendonly.log.  This file will# is read on startup in order to rebuild the full dataset in memory.## Note so 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). # Stil L If append only mode is enabled Redis would load the DATA from the# log file at startup ignoring the Dump.rdb file.## the name of the append only file is "Appendonly.log" # # IMP Ortant:check the bgrewriteaof to Check what rewrite the append# log file in background when it gets too big.# set up Redis service After each operation is completed, whether to update the log operation, if closed, may cause a loss of data over a period of time when the power outage, # because the Redis itself synchronization data files are synchronized according to the save conditions above, so some data will be stored in memory for a period of time. AppendOnly no# Update log file name # Appendfilename appendonly.aof# the Fsync () call tells the Operating System to actually write data On disk# instead to wait for more data in the output buffer.

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 your to# understand if you can relax this to "everysec" that Would fsync every second# or to ' no ' that would 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 Snapshotti ng). # Update log condition with three selectable values: Appendfsync always# appendfsync everysec# appendfsync no############################### Advanced  CONFIG ################################ Glue Small output buffers together in order to send small replies in a# single TCP Packet.

Iv. starting a Redis server

Use the command to start the Redis server.

Redis-server.exe conf/redis.conf

After successful startup, you will see the following prompt:

V. Connect to a REDIS server

The ability to connect to a server is possible using Redis's own commands.

Redis-cli.exe-h localhost-p 6379

After the connection is successful, you will be prompted with the following:

At this point, you will be able to manipulate the data using Redis commands. For other instructions, please check the details on the Internet.
