This README is just a fast quick start document. You can find more detailed documentation at http://redis.io.
Redis is often referred as a data structures server. What this means is that Redis provides access to mutable data structures via a set of commands, which are send using a server-client model with TCP sockets and a simple protocol. So different processes can query and modify the same data structures in a shared way.
Data structures implemented into Redis have a few special properties:
Another good example is to think at Redis as a more complex version of memcached, where the opeations are not just SETs and GETs, but operations to work with complex data types like Lists, Sets, ordered data structures, and so forth.
If you want to know more, this is a list of selected starting points:
Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD. We support big endian and little endian architectures, and both 32 bit and 64 bit systems.
It may compile on Solaris derived systems (for instance SmartOS) but our support for this platform is best effort and Redis is not guaranteed to work as well as in Linux, OSX, and *BSD there.
It is as simple as:
% make
You can run a 32 bit Redis binary using:
% make 32bit
After building Redis is a good idea to test it, using:
% make test
Redis has some dependencies which are included into the deps
directory.
make
does not rebuild dependencies automatically, even if something in the
source code of dependencies is changes.
When you update the source code with git pull
or when code inside the
dependencies tree is modified in any other way, make sure to use the following
command in order to really clean everything and rebuild from scratch:
make distclean
This will clean: jemalloc, lua, hiredis, linenoise.
Also if you force certain build options like 32bit target, no C compiler
optimizations (for debugging purposes), and other similar build time options,
those options are cached indefinitely until you issue a make distclean
command.
If after building Redis with a 32 bit target you need to rebuild it
with a 64 bit target, or the other way around, you need to perform a
make distclean
in the root directory of the Redis distribution.
In case of build errors when trying to build a 32 bit binary of Redis, try the following steps:
make 32bit
:
make CFLAGS="-m32 -march=native" LDFLAGS="-m32"
Selecting a non-default memory allocator when building Redis is done by setting
the MALLOC
environment variable. Redis is compiled and linked against libc
malloc by default, with the exception of jemalloc being the default on Linux
systems. This default was picked because jemalloc has proven to have fewer
fragmentation problems than libc malloc.
To force compiling against libc malloc, use:
% make MALLOC=libc
To compile against jemalloc on Mac OS X systems, use:
% make MALLOC=jemalloc
Redis will build with a user friendly colorized output by default. If you want to see a more verbose output use the following:
% make V=1
To run Redis with the default configuration just type:
% cd src
% ./redis-server
If you want to provide your redis.conf, you have to run it using an additional parameter (the path of the configuration file):
% cd src
% ./redis-server /path/to/redis.conf
It is possible to alter the Redis configuration passing parameters directly as options using the command line. Examples:
% ./redis-server --port 9999 --slaveof 127.0.0.1 6379
% ./redis-server /etc/redis/6379.conf --loglevel debug
All the options in redis.conf are also supported as options using the command line, with exactly the same name.
You can use redis-cli to play with Redis. Start a redis-server instance, then in another terminal try the following:
% cd src
% ./redis-cli
redis> ping
PONG
redis> set foo bar
OK
redis> get foo
"bar"
redis> incr mycounter
(integer) 1
redis> incr mycounter
(integer) 2
redis>
You can find the list of all the available commands at http://redis.io/commands.
In order to install Redis binaries into /usr/local/bin just use:
% make install
You can use make PREFIX=/some/other/directory install
if you wish to use a
different destination.
Make install will just install binaries in your system, but will not configure init scripts and configuration files in the appropriate place. This is not needed if you want just to play a bit with Redis, but if you are installing it the proper way for a production system, we have a script doing this for Ubuntu and Debian systems:
% cd utils
% ./install_server.sh
The script will ask you a few questions and will setup everything you need to run Redis properly as a background daemon that will start again on system reboots.
You'll be able to stop and start Redis using the script named
/etc/init.d/redis_<portnumber>
, for instance /etc/init.d/redis_6379
.
