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.gz3，安装
在/data/work/redis-3.2.9/目录下执行：
make && make install PREFIX = / data / work / redis-3.2.94，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：

aof-rewrite-incremental-fsync yes5，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 [[email protected]](mailto:[email protected]):/data/work/
`#输入181机器密码即可传输数据。`
scp -r /data/work/redis-3.2.9 [[email protected]](mailto:[email protected]):/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 rubygems8，创造实力

>>> 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
