*  序言
 *  安装部署
 *  配置集群

# 序言 #

1.  下载 reids 程序包： [redis-3.2.3.tar.gz][]
2.  下载 ruby 程序包 ： [ruby-2.3.1.tar.gz][]
3.  准备三台CentOS机器：192.168.169.130, 192.168.169.139, 192.168.169.140
4.  将代码包拷贝至 /usr/local 文件夹

# 安装部署 #

1.  准备临时变量方便部署
    
        node1='192.168.169.130'
        node2='192.168.169.139'
        node3='192.168.169.140'
        currIp='192.168.169.130'
        redisDir='/home/redis/redis3.2'
2.  添加用户和用户组
    
        groupadd redis
        useradd -d /home/redis -g redis redis
3.  关闭防火墙
    
        systemctl stop firewalld.service
        systemctl disable firewalld.service
4.  安装必要软件包
    
        yum -y install openssl* openssl-devel zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel
5.  安装编译 Redis
    
        cd /usr/local
        tar -zxvf redis-3.2.3.tar.gz 
        
        mv /usr/local/redis-3.2.3 $redisDir
        cd $redisDir
        make && make install
        chown -R redis:redis $redisDir
6.  配置Reids
    
        mkdir -P $redisDir/log
        cp $redisDir/redis.conf $redisDir/redis.conf.bak#备份文件
        
        echo  "cluster-enabled yes" >>  $redisDir/redis.conf
        echo  "cluster-node-timeout 5000" >>  $redisDir/redis.conf
        sed  -i "s/^appendonly no$/appendonly yes/"   $redisDir/redis.conf 
        sed  -i "s/^daemonize no$/daemonize yes/"   $redisDir/redis.conf 
        echo cluster-config-file node-6379.conf >> $redisDir/redis.conf 
        sed  -i 's/^logfile[^aa]*$/#logfile ""/' $redisDir/redis.conf
        echo "logfile $redisDir/log/redis.log"  >> $redisDir/redis.conf 
        sed -i "s/^bind 127.0.0.1$/bind $currIp/"  $redisDir/redis.conf 
        sed -i "s/^protected-mode yes$/protected-mode no/" $redisDir/redis.conf
7.  启动实例
    
        $redisDir/src/redis-server $redisDir/redis.conf  &

# 配置集群 #

1.  编译 Ruby
    
        mkdir /usr/local/ssl
        cd /usr/local/ssl
        yum -y install wget
        wget --no-check-certificate https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808/raw/ext/openssl/ossl_pkey_ec.c
        wget --no-check-certificate https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808/raw/test/openssl/test_pkey_ec.rb
        
        tar -zxvf  ruby-2.3.1.tar.gz 
        cd /usr/local/ruby-2.3.1
        ./configure --enable-shared --enable-pthread --with-openssl-dir=/usr/local/ssl --prefix=/usr/local/ruby
        make && make install
2.  配置 Ruby 环境
    
        echo 'export PATH=/usr/local/ruby/bin:$PATH' >> /etc/profile
        source /etc/profile
3.  安装 Redis
    
        gem install redis
4.  启动集群
    
        $redisDir/src/redis-trib.rb create  $node1:6379 $node2:6379 $node3:6379
    
    ![redis\_cluster][redis_cluster]
5.  测试
    
        $redisDir/src/redis-cli -c -h 192.168.169.130#注意 -c 开启集群模式
    
    ![testing][]
