#yum -y install wget 安装wget
    #yum search libaio 
    #yum install gcc gcc-c++ ncurses-devel perl 
    #yum install -y unzip zip

下载reids包

$ wget http://download.redis.io/releases/redis-3.2.6.tar.gz
    $ tar xzf redis-3.2.6.tar.gz

先安装编译环境：  
安装cmake

# mkdir /usr/local/cmake
    # cd /usr/local/cmake
    # tar zxvf cmake-2.8.10.2.tar.gz
    # cd cmake-2.8.10.2
    # ./configure
    # make
    # make install
    # cd ~
    # vi /etc/profile
      export PATH=/usr/local/mysql/cmake-2.8.10.2/bin:$PATH #添加这句话
      #source /etc/profile #更新配置
    
    $ cd redis-3.2.6
    $ make

碰到下面的问题

zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
    zmalloc.h:55:2: error: #error "Newer version of jemalloc required"
    make[1]: *** [adlist.o] Error 1
    make[1]: Leaving directory `/data0/src/redis-2.6.2/src'
    make: *** [all] Error 2

解决办法

make MALLOC=libc

$ cd src
    $ make install
    
    $ mkdir /usr/local/redis
    $ mkdir -p /usr/local/redis/etc
    $ mkdir -p /usr/local/redis/bin
    
    $ cp /usr/local/redis-3.2.6/redis.conf  /usr/local/redis/etc
    
    这里要cp好几个
    $ cp /usr/local/redis-3.2.6/src/redis-cli /usr/local/redis/bin
    等等几个启动命令
    
    到/usr/local/redis/bin  
    # ./redis-server
    # ./redis-cli
    以上的是装单个

集群的安装

mkdir -p /usr/local/cluster
    mkdir -p /usr/local/cluster/7000
    mkdir -p /usr/local/cluster/7001
    mkdir -p /usr/local/cluster/7002
    mkdir -p /usr/local/cluster/7003
    mkdir -p /usr/local/cluster/7004
    mkdir -p /usr/local/cluster/7005
    
    cp -rf /usr/local/redis3.2.6/redis.conf /usr/local/cluster/7000/
    cp -rf /usr/local/redis3.2.6/redis.conf /usr/local/cluster/7001/
    cp -rf /usr/local/redis3.2.6/redis.conf /usr/local/cluster/7002/
    cp -rf /usr/local/redis3.2.6/redis.conf /usr/local/cluster/7003/
    cp -rf /usr/local/redis3.2.6/redis.conf /usr/local/cluster/7004/
    cp -rf /usr/local/redis3.2.6/redis.conf /usr/local/cluster/7005/
    
    修改配置文件
    vi /usr/local/cluster/7000/redis.conf
    这几个
    port 7000
    daemonize yes
    cluster-enabled yes
    cluster-config-file nodes.conf
    cluster-node-timeout 5000
    appendonly yes
    bind 本地ip地址
    
    vi /usr/local/cluster/7001/redis.conf
    vi /usr/local/cluster/7002/redis.conf
    vi /usr/local/cluster/7003/redis.conf
    vi /usr/local/cluster/7004/redis.conf
    vi /usr/local/cluster/7005/redis.conf
    
    启动
    /usr/local/redis/bin/redis-server /usr/local/redis-cluster/7001/redis.conf
    /usr/local/redis/bin/redis-server /usr/local/redis-cluster/7002/redis.conf
    ...
    
    查看是否启动成功
    ps -ef|grep redis 或者 ps -aux |grep redis
    如果启动成功
    cd /usr/local/redis-3.2.6/src/
    ./redis-trib.rb  create --replicas 1 127.0.0.1:7000 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
    
    或者（最好是这样启动）
    ./redis-trib.rb  create --replicas 1 192.168.63.129:7001 192.168.63.129:7002 192.168.63.129:7003 192.168.63.129:7004 192.168.63.129:7005 192.168.63.129:7006
    
    redis.conf中配置的pind是多少就是多少
    
    如果不成功就安装ruby
    
    yum install ruby
    yum install rubygems
    gem install redis
    如果下载不下来
    （redis高版本可能用不了）
    wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
    gem install -l ./redis-3.2.1.gem
    
    ./redis-trib.rb  create --replicas 1 192.168.63.129:7001 192.168.63.129:7002 192.168.63.129:7003 192.168.63.129:7004 192.168.63.129:7005 192.168.63.129:7006
    启动完毕

![这里写图片描述][SouthEast]

则集群成功

进入集群
    （redis-cli -c -p 7000）
    
    连接一个单独的Redis   ：cd 到一个Redis 目录下 使用命令 ./redis-cli -h 192.168.63.129 -p 7001
    
    到redis安装目录的src目录下连接集群则在其后加入一个 -c 即 ./redis-cli -h 192.168.63.129 -p 7001 -c
