Getting started with Redis configuration and C ++ in Ubuntu

Getting started with Redis configuration and C ++ in Ubuntu

Redis is a high-performance key-value database. The emergence of Redisedis largely compensates for the shortage of key/value storage such as memcached. In some cases, it can complement relational databases. It provides clients such as Java, C/C ++, C #, PHP, JavaScript, Perl, Object-C, Python, Ruby, and Erlang for ease of use.

This article introduces the configuration of Redis in Ubuntu and how to get started with C ++ to help readers get started with Redis quickly.

Install configurations

Obtain, decompress, enter the source code directory, and compile

$ Wget http://download.redis.io/releases/redis-2.8.13.tar.gz
$ Tar xzf redis-2.8.13.tar.gz
$ Redis-2.8.13 cd
$ Make

Testing and Installation

$ Make-test
$ Sudo make install

After the make command is executed, an executable file is generated under the src directory, including redis-server, redis-cli, redis-benchmark, and redis-stat. Their functions are as follows:
 
Redis-server: daemon Startup Program of the Redis server
Redis-cli: Redis command line operation tool. Of course, you can also use telnet to operate based on its plain text protocol.
Redis-benchmark: Redis performance testing tool to test the read/write performance of Redis in your system and your configuration
Redis-stat: Redis status detection tool that can detect the current status parameters and latency of Redis.

Run Redis:

$ Src/redis-server

You can interact with Redis using the built-in client:

$ Src/redis-cli
Redis> set foo bar
OK
Redis> get foo
"Bar"

C ++ configuration and getting started

Configuration

On Ubuntu:

$ Apt-get install libhiredis-dev

On OSX run:

$ Brew install hiredis

On other platforms:

$ Git clone https://github.com/antirez/hiredis.git & cd hiredis & make & sudo make install & sudo ldc

Otherwise, an error may occur due to the lack of hiredis dependency:

Error: hiredis/hiredis. h: No such file or directory

Getting started

RedisTest. cpp

# Include <stdio. h>
# Include

Int main ()
{
RedisContext * conn = redisConnect ("Wagner. 0.0.1", 6379 );
If (conn-> err ){
Printf ("connection error: % s \ n", conn-> errstr );
}

& Nbsp; redisReply * reply = (redisReply *) redisCommand (conn, "set foo 1234 ");
FreeReplyObject (reply );

& Nbsp; reply = (redisReply *) redisCommand (conn, "get foo ");
Printf ("% s \ n", reply-> str );
FreeReplyObject (reply );

& Nbsp; redisFree (conn );
Return 0;
}

Compile command

G ++ redisTest. cpp-o redisTest-I./deps/hiredis/-L./deps/hiredis/-lhiredis
