Centos7 installs Redis cluster​

Reference: https://me.jinchuang.org/archives/1104.html
The Redis cluster installation steps are completely based on the above blog content.

Virtual machine preparation​

Use 3 machines, each machine has 2 nodes, system centos7, each machine communicates with each other
192.168.1.2 represents the first machine ip
192.168.1.3 represents the second machine ip
192.168.1.4 represents the third machine ip

Upgrade gcc [execute on all 3 machines]​
     安装ruby
    yum install ruby rubygems -y
     升级gcc（数字7表示7.x版本，8表示8.x版本）
    yum install centos-release-scl devtoolset-7-gcc* -y
    临时生效gcc版本
    scl enable devtoolset-7 bash
     永久生效gcc版本
    echo 'source /opt/rh/devtoolset-7/enable' >>/etc/profile && source /etc/profile
Download and install Redis [execute on all 3 machines]​

Create a new software directory on the virtual machine, for example: /root/software

    进入software目录 
    cd software
    [redis](/search?q=redis)
    wget http://download.redis.io/releases/redis-6.0.6.tar.gz
    解压缩
    tar xf redis-6.0.6.tar.gz
    cd redis-6.0.6
    编译安装
    make
    make install PREFIX=/usr/local/redis
    echo 'export PATH=$PATH:/usr/local/redis/bin' >>/etc/profile && source /etc/profile
Create directories and configuration files​
    # 第一台
    mkdir -p /opt/redis-cluster/{7001,7002} 
    # 第二台
    mkdir -p /opt/redis-cluster/{7003,7004} 
    # 第三台
    mkdir -p /opt/redis-cluster/{7005,7006} 
    
    # 配置文件模板以7001节点为例(这里绑定本机ip和127.0.0.1)，复制到其他节点目录下并改下ip和端口还有文件名称
    cd /opt/redis-cluster/7001/
    vim redis7001.conf

The content of the configuration file, taking node 7001 as an example:

    # 配置内容
    bind 192.168.1.2 127.0.0.1
    port 7001
    daemonize yes
    cluster-enabled yes
    cluster-config-file nodes7001
