Installation of Redis

1, 第一步，下载，解压，编译，安装
 
$ wget http://download.redis.io/releases/redis-3.0.3.tar.gz$ tar xzf redis-3.0.3.tar.gz$ cd redis-3.0.3$ make
$ cd src && make installed

在当前目录生成配置文件, 并复制到/etc目录
$cp redis.conf /etc/

When the make install command finishes executing, the executable is generated in the/usr/local/bin directory, respectively, Redis-server, REDIS-CLI, Redis-benchmark, Redis-check-aof, Redis-check-dump, they function as follows:

Redis-server:redis Server Daemon Startup program

Redis-cli:redis command-line operation tool. You can also use Telnet to manipulate it based on its plain text protocol.

Redis-benchmark:redis Performance Testing tool to test Redis's read and write performance under current system

REDIS-CHECK-AOF: Data Repair

Redis-check-dump: Check the Export tool

2. Start and check of service

To start and run Redis:

A) $ cd/usr/local/bin

b)./redis-server/etc/redis.conf

Open another window and log in to Redis, first to see if Redis started successfully

c). Check whether the start is successful

$ PS-EF | grep Redis

d). Log in to the Redis client

$/usr/local/bin/redis-cli

>set name Liming

>get Name

3, configuration file parameters Introduction

Daemonize: Whether to run daemon mode later

Pidfile:pid File Location

Port: Port number for listening

Timeout: Request time-out

Loglevel:log Information level

Logfile:log File Location

Databases: number of open databases

Save *: How often the snapshot is saved, the first * indicates how long, and the third * indicates how many times the write operation is performed. Snapshots are automatically saved when a certain number of writes are performed within a certain amount of time. You can set multiple conditions.

Rdbcompression: Whether to use compression

Dbfilename: Data Snapshot file name (only file name, excluding directory)

Dir: Save directory for Data snapshot (this is the directory)

AppendOnly: If the appendonlylog is turned on, each write will record a log, which will improve the data anti-risk ability, but affect the efficiency.

Appendfsync:appendonlylog How to sync to disk (three options, each write is forced to call Fsync, Fsync per second, do not call Fsync wait for the system to synchronize itself)
