Redis Installation (standalone)

Prior to a period of time due to business needs to study the next Redis-related information, redex from single-machine to cluster configuration of the various configurations in the personal blog update, so that the need for friends.

1 Overview

Redis is an open source, Key-value database, written in C, that supports network interaction and can be memory-based and persistent. Redis pioneered a new approach to data storage, and using Redis, we don't have to focus on the problem of how to put an elephant into a refrigerator in the face of a monotonous database, but instead use Redis's flexible data structure and data manipulation to build different refrigerators for different elephants.

Today most NoSQL databases are essentially key-value pairs, and Redis is no exception. As a cache database, compared with memcached, there are several main advantages:

(1) speed, Redis is faster than memcached, this is based on some benchmarks test results, and in memory use, Redis broke through the physical memory limit, can use virtual memory;

(2) More data types than memcached, Redis supports list, Set, SortedSet, HashMap and other data structures;

(3) Persistence, memcached does not have a corresponding persistence mechanism, and Redis has an RDB snapshot and aof log two forms of the combination of persistence, to a large extent to ensure the persistence of data and security, not like memcached after the power outage.

Redis is a good alternative to memcached.

2.2 Installation Steps

The installation steps are as follows:

(1) Copy the redis-3.0.1.tar.gz installation package to our designated directory;

(2) Use the command TAR-ZXVF redis-3.0.1.tar.gz to extract the tar package, get the redis-3.0.1 directory;

(3) Enter the redis-3.0.1 directory, execute the make command to compile (you can also specify the appropriate compiled installation directory such as:

$ make Prefix=/usr/local/redis Install #安装到指定目录中

(4) After the compilation, configure the redis.conf file, set the "Daemonize" property to "yes", indicating that we will start the Redis service as a background process, set the "Port" property to the specified port, where the default is "6379"; "LogFile" property is set to the specified log path, and the remaining properties can remain the default.

(5) using the command src/redis-server./redis.conf starts the Redis service, and after startup, you can see similar information in the log path that you just configured:

The following action script:

Installation
Download, extract and compile Redis with:
$cd/usr/software
$mkdir redis
$cd redis
$ wget http://download.redis.io/releases/redis-3.0.1.tar.gz
$ tar xzf redis-3.0.1.tar.gz
$ cd redis-3.0.1
$ view Current operating system
$ if it is 32 bit: Make cflags= "-march=i686"
$ if it is 64 bit: Make $ make the binaries that is now
compiled a Re available in the srcdirectory. Run Redis with:

Note that the above run script, if make fails, is generally not installed in the system GCC, then can be installed through Yum:

$ yum Install gcc

Redis has been installed to completion.

When make succeeds, some binaries are generated under the SRC folder, including Redis-server, REDIS-CLI, and so on:

Description :

$ find. -type f–executable

./redis-benchmark//tools for Redis performance testing
./redis-check-dump//used to fix problems with Dump.rdb files
. REDIS-CLI//redis client
./redis-server//redis server
./redis-check-aof//used to fix problems with aof files
. Redis-sentinel//For cluster management

2.3 Complete the test

Modify the redis.conf configuration file under the installation directory;

Modify the Daemonize key parameter to set to Yes (set to run in the future daemon mode)

Open:

$./src/redis-server  ./redis.conf

Redis uses 6379 as a service port by default

Close
$./src/redis-cli shutdown
 
Simple test:
$./src/redis-cli
redis> set name bar
OK
redis> get Name
"Bar"
