### 一、部署环境 ###

单节点多实例

### 二、安装ruby环境 ###

#### 步骤一：安装ruby环境，创建集群时的脚本需要ruby环境。 ####

> \[root@redis-cluster01 ~\]\# yum install ruby rubygems -y

#### 步骤二：安装国内gem源 ####

> \[root@redis-cluster01 ~\]\# gem sources --add [https://gems.ruby-china.com/][https_gems.ruby-china.com] \--remove [https://rubygems.org/][https_rubygems.org]  
> [https://gems.ruby-china.com/][https_gems.ruby-china.com] added to sources  
> [https://rubygems.org/][https_rubygems.org] removed from sources  
> \[root@redis-cluster01 ~\]\# gem sources -l  
> \*\*\* CURRENT SOURCES \*\*\*  
> [https://gems.ruby-china.com/][https_gems.ruby-china.com]

#### 步骤三：gem安装redis ####

> \[root@redis-cluster01 ~\]\# gem install redis  
> Fetching: redis-4.1.0.gem (100%)  
> ERROR: Error installing redis:  
> redis requires Ruby version >= 2.2.2.

### 三、部署redis集群环境 ###

#### 步骤一：配置单节点多实例环境 ####

> \[root@redis-cluster01 ~\]\# mkdir /application/redis-cluster  
> \[root@redis-cluster01 ~\]\# mkdir /application/redis-cluster/\{7000,7001,7002,7003,7004,7005\}  
> \[root@redis-cluster01 ~\]\# for num in `seq 7000 7005`;do cp /application/redis/\{redis.conf,redis-cli,redis-server\} /application/redis-cluster/$\{num\}/;done  
> \[root@redis-cluster01 ~\]\# cat [redis-cluster.sh][]  
> \#!/bin/bash  
> Redis\_Dir=/application/redis-cluster/  
> Redis\_Config=redis.conf  
> cd $\{Redis\_Dir\}  
> for num in `seq 7000 7005`  
> do  
> sed -i “s/port 6379/port $num/g”  n u m / \{num\}/ num/\{Redis\_Config\}  
> sed -i “s\#/var/run/redis\_6379.pid\#/var/run/redis\_$\{num\}.pid\#g”  n u m / \{num\}/ num/\{Redis\_Config\}  
> sed -i “s/appendonly no/appendonly yes/g”  n u m / \{num\}/ num/\{Redis\_Config\}  
> echo “cluster-enabled yes” >> n u m / \{num\}/ num/\{Redis\_Config\}  
> echo "cluster-config-file  n u m n o d e s . c o n f " > > \{num\}\_nodes.conf" >> numnodes.conf">>\{num\}/ R e d i s C o n f i g e c h o " c l u s t e r − n o d e − t i m e o u t 5000 " > > \{Redis\_Config\} echo "cluster-node-timeout 5000" >> RedisConfigecho"cluster−node−timeout5000">>\{num\}/$\{Redis\_Config\}  
> done  
> \[root@redis-cluster01 ~\]\# bash [redis-cluster.sh][]

#### 步骤二：启动所有实例 ####

> \[root@redis-cluster01 ~\]\# cat rcluster\_start.sh  
> \#!/bin/bash  
> Redis\_Dir=/application/redis-cluster/  
> Redis\_Config=redis.conf  
> cd $\{Redis\_Dir\}  
> for num in `seq 7000 7005`  
> do  
> $\{num\}/redis-server $\{num\}/redis.conf  
> done  
> \[root@redis-cluster01 ~\]\# bash rcluster\_start.sh  
> 31495:C 22 Apr 20:37:52.783 \# oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo  
> 31495:C 22 Apr 20:37:52.784 \# Redis version=4.0.9, bits=64, commit=00000000, modified=0, pid=31495, just started  
> 31495:C 22 Apr 20:37:52.784 \# Configura  
> …  
> .  
> .

#### 步骤三：查看端口 ####

> \[root@redis-cluster01 ~\]\# ss -lntup|grep 700\*  
> tcp LISTEN 0 128 10.0.0.70:17000 *:* users:((“redis-server”,pid=31496,fd=9))  
> tcp LISTEN 0 128 10.0.0.70:17001 *:* users:((“redis-server”,pid=31498,fd=9))  
> tcp LISTEN 0 128 10.0.0.70:17002 *:* users:((“redis-server”,pid=31500,fd=9))  
> tcp LISTEN 0 128 10.0.0.70:17003 *:* users:((“redis-server”,pid=31508,fd=9))  
> tcp LISTEN 0 128 10.0.0.70:17004 *:* users:((“redis-server”,pid=31513,fd=9))  
> tcp LISTEN 0 128 10.0.0.70:17005 *:* users:((“redis-server”,pid=31518,fd=9))  
> tcp LISTEN 0 128 10.0.0.70:7000 *:* users:((“redis-server”,pid=31496,fd=6))  
> tcp LISTEN 0 128 10.0.0.70:7001 *:* users:((“redis-server”,pid=31498,fd=6))  
> tcp LISTEN 0 128 10.0.0.70:7002 *:* users:((“redis-server”,pid=31500,fd=6))  
> tcp LISTEN 0 128 10.0.0.70:7003 *:* users:((“redis-server”,pid=31508,fd=6))  
> tcp LISTEN 0 128 10.0.0.70:7004 *:* users:((“redis-server”,pid=31513,fd=6))  
> tcp LISTEN 0 128 10.0.0.70:7005 *:* users:((“redis-server”,pid=31518,fd=6))

#### 步骤四:拷贝redis-trib.rb脚本,部署集群 ####

> \[root@redis-cluster01 ~\]\# cp redis-4.0.9/src/redis-trib.rb /application/redis-cluster/  
> \[root@redis-cluster01 ~\]\# ruby /application/redis-cluster/redis-trib.rb create --replicas 1 10.0.0.70:7000 10.0.0.70:7001 10.0.0.70:7002 10.0.0.70:7003 10.0.0.70:7004 10.0.0.70:7005

#### 步骤五：登录查看 ####
