  • 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

    1. node1='192.168.169.130'
    2. node2='192.168.169.139'
    3. node3='192.168.169.140'
    4. currIp='192.168.169.130'
    5. redisDir='/home/redis/redis3.2'

  2. 添加用户和用户组

    1. groupadd redis
    2. useradd -d /home/redis -g redis redis

  3. 关闭防火墙

    1. systemctl stop firewalld.service
    2. systemctl disable firewalld.service

  4. 安装必要软件包

    1. 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

    1. cd /usr/local
    2. tar -zxvf redis-3.2.3.tar.gz 
    4. mv /usr/local/redis-3.2.3 $redisDir
    5. cd $redisDir
    6. make && make install
    7. chown -R redis:redis $redisDir

  6. 配置Reids

    1. mkdir -P $redisDir/log
    2. cp $redisDir/redis.conf $redisDir/redis.conf.bak#备份文件
    4. echo  "cluster-enabled yes" >>  $redisDir/redis.conf
    5. echo  "cluster-node-timeout 5000" >>  $redisDir/redis.conf
    6. sed  -i "s/^appendonly no$/appendonly yes/"   $redisDir/redis.conf 
    7. sed  -i "s/^daemonize no$/daemonize yes/"   $redisDir/redis.conf 
    8. echo cluster-config-file node-6379.conf >> $redisDir/redis.conf 
    9. sed  -i 's/^logfile[^aa]*$/#logfile ""/' $redisDir/redis.conf
    10. echo "logfile $redisDir/log/redis.log"  >> $redisDir/redis.conf 
    11. sed -i "s/^bind 127.0.0.1$/bind $currIp/"  $redisDir/redis.conf 
    12. sed -i "s/^protected-mode yes$/protected-mode no/" $redisDir/redis.conf

  7. 启动实例

    1. $redisDir/src/redis-server $redisDir/redis.conf  &

配置集群

  1. 编译 Ruby

    1. mkdir /usr/local/ssl
    2. cd /usr/local/ssl
    3. yum -y install wget
    4. wget --no-check-certificate https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808/raw/ext/openssl/ossl_pkey_ec.c
    5. wget --no-check-certificate https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808/raw/test/openssl/test_pkey_ec.rb
    7. tar -zxvf  ruby-2.3.1.tar.gz 
    8. cd /usr/local/ruby-2.3.1
    9. ./configure --enable-shared --enable-pthread --with-openssl-dir=/usr/local/ssl --prefix=/usr/local/ruby
    10. make && make install

  2. 配置 Ruby 环境

    1. echo 'export PATH=/usr/local/ruby/bin:$PATH' >> /etc/profile
    2. source /etc/profile

  3. 安装 Redis

    1. gem install redis

  4. 启动集群

    1. $redisDir/src/redis-trib.rb create  $node1:6379 $node2:6379 $node3:6379

    redis\_cluster

  5. 测试

    1. $redisDir/src/redis-cli -c -h 192.168.169.130#注意 -c 开启集群模式

    testing
