centos7部署redis_3.2.9 cluster部署（三主三从

1，虚拟机环境

使用的Linux环境已经版本：

Centos 7 64位系统

主机ip ：

192.168.56.180

192.168.56.181

192.168.56.182

每台服务器是1主1从，实验3台服务器课成为3主3从。

Redis安装的项目目录，日志，配置文件等都存放在/ root / svr /目录下。

2，下载相关的安装包以及解压

首先在192.168.56.180机器操作：

cd /data/work/
wget http://download.redis.io/releases/redis-3.2.9.tar.gz
tar -zxvf redis-3.2.9.tar.gz

3，安装

在/data/work/redis-3.2.9/目录下执行：

make && make install PREFIX = / data / work / redis-3.2.9

4，配置信息

创建性能配置，日志日志，数据所在的文件夹：

cd /data/work/redis-3.2.9/`
mkdir cluster-conf`

mkdir -pv /data/work/redis-3.2.9/logs

 创建可用端口文件夹：

cd cluster-conf
mkdir 7777
mkdir 8888

 配置复制文件到/数据/工作/redis-3.2.9/cluster-conf/7777目录下：

cp /data/work/redis-3.2.9/redis.conf  /data/work/redis-3.2.9/cluster-conf/7777

• 修改7777目录下redis.conf（主）配置文件：

bind 192.168.56.181 127.0.0.1
protected-mode yes
masterauth "xxxxx"
requirepass "xxxxx"

• 群集配置文件/data/work/redis-3.2.9/cluster-conf/8888/redis.conf (从)

bind 192.168.56.181 127.0.0.1

5，使用scp复制安装和配置好的redis复制到其他服务器上

已经在192.168.56.180机器配置好，复制到181和182机器

在两台新机器上创建文件夹

scp -r /data/work/redis-3.2.9 [root@192.168.56.181](mailto:root@192.168.56.181):/data/work/
`#输入181机器密码即可传输数据。`



scp -r /data/work/redis-3.2.9 [root@192.168.56.182](mailto:root@192.168.56.182):/data/work/`
`#输入182机器密码即可传输数据。`

6，启动3台机器的redis

3台机器执行启动方式：

/data/work/redis-3.2.9/bin/redis-server /root/svr/redis-3.2.9/cluster-conf/7777/redis.conf &
/data/work/redis-3.2.9/bin/redis-server /root/svr/redis-3.2.9/cluster-conf/8888/redis.conf &

 查看状态是否：

ps -ef|grep redis

7，安装ruby2.4.0

gpg2 --recv键409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
`yum -y update nss`

curl -sSL [https://get.rvm.io](https://get.rvm.io/) | bash -s稳定

源/etc/profile.d/rvm.sh

rvm安装2.4.0

rvm使用2.4.0

gem install redis

yum install rubygems

8，创造实力

/data/work/redis-3.2.9/src/redis-trib.rb create --replicas 1 192.168.56.180:7777 192.168.56.180:8888 192.168.56.181:7777 192.168.56.181:8888 192.168.56.182:7777 192.168.56.182:8888

无法创建，提示错误信息：

>>> Creating cluster
[ERR] Sorry, can't connect to node 192.168.56.180:7777

修改配置文件redis.conf的权限设置安全密码（密码自定义设置）

requirepass "xxxxx"   #权限密码`

masterauth "xxxxx"

• 设置密码之后如果需要使用redis-trib.rb的各种命令

如：./redis-trib.rb check 127.0.0.1:7000，则会报错ERR] Sorry, can’t connect to node 127.0.0.1:7000
解决办法：vim /usr/local/rvm/gems/ruby-2.3.3/gems/redis-4.0.0/lib/redis/client.rb，然后修改passord

find / -name client.rb

vim /usr/local/rvm/gems/ruby-2.4.0/gems/redis-4.2.5/lib/redis/client.rb

1 # frozen_string_literal: true
.

.

18 connect_timeout: nil,
19 timeout: 5.0,
20 password: "xxxxx", #######修改这里的密码（每台机器做同样的操作）

**注意：client.rb路径可以通过find命令查找：find / -name 'client.rb'**
带密码访问集群

/data/work/redis-3.2.9/bin/redis-cli -c -p 8888 -a xxxxx

 >>> Performing Cluster Check (using node 127.0.0.1:7777)
M: d8xxxefxxxxxxxxxxxxxxxxxx2 127.0.0.1:7777
slots: (0 slots) master
0 additional replica(s)
[OK] All nodes agree about slots configuration.

9、测试集群

OK
