  • 2: Download redis related software
  • Three: Installation
  • Four: Cluster creation

1: Environment preparation​

Two virtual machines CentOS-7 + redis-4.0.1
two nodes + 6 redis instances

Download the redis software, download address , select the version to download, I use wget to download directly, the command is as follows:

    wget http://download.redis.io/releases/redis-4.0.1.tar.gz

Download ruby , select tar.gz to download

After the download is complete, place the software into the /usr/local/soft directory.
Building a redis cluster with three masters and three slaves

Three: Installation​

3.1 Install redis

Install some dependencies required by redis

    yum install -y tcl gcc zlib-devel openssl-devel

Unzip redis

    tar -zxvf redis-4.0.1.tar.gz
    
    #解压后
    mv redis-4.0.1 redis
    make MALLOC=libc
    
    #创建redis集群的目录
    cd /opt
    mkdir redis-cluster
    mkdir redis-cluster/nodes-{
       7001,7002,7003}
    
    #编辑redis.conf配置文件（以7001来举个例子，将7002和7003都编辑一下配置文件）
    cd redis-cluster/nodes-7001
    vi redis.conf
    
    #redis.conf
    bind 192.168.1.39
    port 7001 
    pidfile redis_7001.pid 
    loglevel notice
    logfile "/opt/redis-cluster/nodes-7001/redis_7001.log" 
    dir /opt/redis-cluster/nodes-7001/ 
    cluster-config-file nodes-7001.conf
    daemonize yes
    supervised no
    appendonly yes
    cluster-enabled yes
    cluster-node-timeout 15000
    save 900 1
    save 300 10
    save 60 10000

On another machine, repeat the above steps, but make it 7001, 7002, 7003

Start each redis instance in sequence (use 7001 as a reference)

Just execute the following commands on both machines:

    cd /usr/local/redis/src
    ./redis-server /opt/redis-cluster/nodes-7001/redis.conf
    ./redis-server /opt/redis-cluster/nodes-7002/redis
