• redis 安装


    一.安装必要包

    yum install gcc

    二.linux下安装

    #下载
    wget http://download.redis.io/releases/redis-3.0.0.tar.gz
    tar zxvf redis-3.0.0.tar.gz
    cd redis-3.0.0
    #如果不加参数,linux下会报错
    # make MALLOC=libc
    make PREFIX=/mnt/redis install

     安装好之后,启动文件

    #启动redis
    src/redis-server &
    
    #关闭redis
    src/redis-cli shutdown

    测试redis

    $ src/redis-cli
    127.0.0.1:6379> set foo bar
    OK
    127.0.0.1:6379> get foo
    "bar"
    $ 

    测试成功

    3.redis cluster集群搭建

    建立本机测试环境

    建立运行目录

    #建立redis运行目录
    mkdir -p redis-server/7000/
    #复制默认的配置文档
    cp redis-3.0.0/redis.conf redis-server/redis.default.conf
    #把编译好的server复制到运行目录
    cp redis-3.0.0/src/redis-server redis-server/7000/

    建立独立配置文件

    #在7000目录下建立redis的配置文档
    vim redis-server/7000/redis.conf

    文件内容

    复制代码
    #redis-server/7000/redis.conf
    include /root/redis-server/redis.default.conf
    pidfile /var/run/redis-7000.pid
    port 7000
    cluster-enabled yes
    cluster-config-file redis-node-7000.conf
    cluster-node-timeout 5000
    appendonly yes
    复制代码

    复制运行目录(模拟集群环境)

    #复制目录
    cp -R 7000/ 7001/
    cp -R 7000/ 7002/
    cp -R 7000/ 7003/
    cp -R 7000/ 7004/
    cp -R 7000/ 7005/

    修改相应配置文件的端口和文件名

    建立启动脚本 redis-server/redis-start.sh

    复制代码
    #!/bin/sh
    /root/redis-server/7000/redis-server /root/redis-server/7000/redis.conf &
    /root/redis-server/7001/redis-server /root/redis-server/7001/redis.conf &
    /root/redis-server/7002/redis-server /root/redis-server/7002/redis.conf &
    /root/redis-server/7003/redis-server /root/redis-server/7003/redis.conf &
    /root/redis-server/7004/redis-server /root/redis-server/7004/redis.conf &
    /root/redis-server/7005/redis-server /root/redis-server/7005/redis.conf &
    复制代码

    配置集群

    安装ruby

    yum install ruby-devel.x86_64

    安装redis gem 

    # gem install redis
    Fetching: redis-3.2.1.gem (100%)
    Successfully installed redis-3.2.1
    Parsing documentation for redis-3.2.1
    Installing ri documentation for redis-3.2.1
    1 gem installed

    使用脚本建立集群机制  

    在create的时候,加上参数--replicas 1 表示为每个master分配一个salve,如例子,则是3个master 3个salve

    复制代码
    # ./redis-trib.rb create 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

    复制代码

     如果需要全部重新自动配置,则删除所有的配置好的cluster-config-file,重新启动所有的redis-server,然后重新执行配置命令即可
