redis详解之cluster模式部署

一、环境说明

1.Operation OS:CentOS7.2
2.ruby version >= 2.2.2
3.openssl zlib gcc>=4.8.5

二、开始部署

1.安装ruby

# 下载ruby2.6.5(latest stable version)
[root@localhost ~]# wget https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.5.tar.gz

# 解压并修改目录名称
[root@localhost ~]# tar -zxvf ruby-2.6.5.tar.gz -C /usr/local
[root@localhost ~]# mv /usr/local/ruby-2.6.5  /usr/local/ruby

# 生成MakeFile文件
[root@localhost ~]# cd /usr/local/ruby
[root@localhost ruby]# ./configure

# 编译安装
[root@localhost ruby]# make -j 8 && make install

# 查看ruby版本
[root@localhost ruby]# ruby --version
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux]

 2.安装redis

# 下载redis
[root@localhost ~]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz

# 解压并修改目录
[root@localhost ~]# tar -zxvf redis-4.0.6.tar.gz -C /usr/local
[root@localhost ~]# mv /usr/local/redis-4.0.6 /usr/local/redis

# 安装
[root@localhost ~]# cd /usr/local/redis
[root@localhost redis]# make -j 8 && make install

 3.创建集群

# 安装redis所需要的插件
[root@localhost ~]# gem install redis

# 启动集群
[root@localhost ~]# cd /usr/local/redis/utils/create-cluster
[root@localhost create-cluster]# ./create-cluster start

Starting 30002
Starting 30003
Starting 30004
Starting 30005
Starting 30006

# 创建集群配置文件
[root@localhost create-cluster]# ./create-cluster create

 4.注意

1> ruby版本必须大于等于2.2.2，否则gem install redis会报错；

2> 必须安装openssl zlib插件，否则gem install redis也会报错，yum安装如下

[root@localhost ~]# yum install openssl openssl-devel zlib zlib-devel -y
