Redis 3.0.2高可用集群（中）------ Redis-Cluster部署

9404803

         好，原文再续，书接上一回，上回我介绍了一下Redis的安装，这回我们来配一下集群------Redis Cluster
 

Redis-Cluster安装部署步骤

 
1.         下载zlib-1.2.8.tar.gz、ruby-2.2.2.tar.gz、rubygems-2.4.8.tgz和redis-3.2.1.gem(ruby安装包比较大、rubygem的文件格式不能上传，所以大家自己想办法，其他两个见附件)
 
2.          安装：
    1)        安装zlib
           a)        tar –zxvf  zlib-1.2.8.tar.gz
           b)        cd zlib-1.2.8
           c)      ./configure
           d)        make
           e)        make install
 
     2)         安装ruby
    a)        tar –zxvf  ruby-2.2.2.tar.gz
    b)      cd  ruby-2.2.2
    c)         ./configure -prefix=/usr/local/ruby
    d)       make
    e)         make  install
    f)        sudo cp ruby /usr/local/bin
 
      3)          安装rubygems
            a)       tar –zxvf  rubygems-2.4.8.tgz
            b)     cd rubygems-2.4.8
            c)      sudo ruby setup.rb 
            d)     sudo cp bin/gem /usr/local/bin  
      4)         安装ruby-redis-3.2.1.gem插件
             a)        gem install -l ruby-redis-3.2.1.gem
           
 
       5)        配置redis-cluster启动脚本 
              a)        cd /%redis_home%/src  redis-trib.rb  /usr/local/bin/redis-trib
 
 3.         部署

A机10.92.21.17	实例1端口6379 实例2 端口7379 实例3 端口8379
B机10.92.21.18	实例1端口6380 实例2 端口7380 实例3 端口8380

 
       1.         A/B机 mkdir  /opt/redis
       2.         cd /opt/redis
       3.         mkdir  6379/ 7379/ 8379/6380/ 7380/ 8380
       4.       cd 6379/ 7379/ 8379/6380/ 7380/ 8380
       5.       cp /%redis_home%/redis_conf  6379.conf/7379.conf/8379.conf

      6.         编写实例启动脚本 stop.sh

 

killall redis-server
sudo rm /opt/redis/6379(6380)/*.aof
sudo rm /opt/redis/6379(6380)/node*
sudo rm /opt/redis/7379(7380)/*.aof
sudo rm /opt/redis/7379(7380)/node*
sudo rm /opt/redis/8379(8380)/*.aof
sudo rm /opt/redis/8379(8380)/node*
  7          编写实例启动脚本 startRedis.sh
redis-server /opt/redis/6379(6380)/6379(6380).conf
redis-server /opt/redis/7379(7380)/7379(7380).conf
redis-server /opt/redis/8379(8380)/8379(8380).conf

 



     8.          Chmod  777  -R  /opt/redis 对opt/redis目录赋权限
     9.        在opt/redis目录执行 stop.sh和startRedis.sh即可进行多个实例的启动
     10.       redis-trib create --replicas 1 10.92.21.17:6379 10.92.21.17:7379  10.92.21.17:8379 10.92.21.18:6380 10.92.21.18:7380 10.92.21.18:8380
这里有个地方需要注意的，我不确定是不是个bug，如果 redis-trib create在A机上执行，那么把10.92.21.17改成127.0.0.1的同时把A的3个实例同时放到前三位，即redis-trib create --replicas 1 127.0.0.1:6379 127.0.0.1:7379  127.0.0.1:8379 10.92.21.18:6380 10.92.21.18:7380 10.92.21.18:8380的话就会启动不redis-cluster,会一直卡在waiting the cluster join.....
