redis cluster 集群 安装 配置 详解

Redis 集群是一个提供在多个Redis间节点间共享数据的程序集.redis3.0以前，只支持主从同步的，如果主的挂了，写入就成问题了。3.0出来后就可以很好帮我们解决这个问题。

目前redis 3.0还不稳定，如果要用在生产环境中，要慎重。

 

一，redis服务器说明

  • 192.168.10.219 6379 
  • 192.168.10.219 6380 
  • 192.168.10.219 6381 
  •  
  • 192.168.10.220 6382 
  • 192.168.10.220 6383 
  • 192.168.10.220 6384 
    • 192.168.10.219 6379 192.168.10.219 6380 192.168.10.219 6381192.168.10.220 6382 192.168.10.220 6383 192.168.10.220 6384

    要让集群正常运作至少需要三个主节点，不过在刚开始试用集群功能时， 强烈建议使用六个节点： 其中三个为主节点， 而其余三个则是各个主节点的从节点。所有用二台机器，开6个redis进程，模拟6台机器。

    二，安装ruby,rubygems

    查看复制打印?
  • # yum -y install gcc openssl-devel libyaml-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel gcc-c++ automake autoconf 
  •  
  • # yum -y install ruby rubygems   //安装ruby rubygems 
  •  
  • //换源 
  • # gem source -l 
  • # gem source --remove http://rubygems.org/ 
  • # gem sources -a http://ruby.taobao.org/ 
  • # gem source -l 
  •  
  • # gem install redis --version 3.0.0  //安装gem_redis 
  • Successfully installed redis-3.0.0 
  • 1 gem installed 
  • Installing ri documentation for redis-3.0.0... 
  • Installing RDoc documentation for redis-3.0.0... 
    • # yum -y install gcc openssl-devel libyaml-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel gcc-c++ automake autoconf# yum -y install ruby rubygems //安装ruby rubygems//换源 # gem source -l # gem source --remove http://rubygems.org/ # gem sources -a http://ruby.taobao.org/ # gem source -l# gem install redis --version 3.0.0 //安装gem_redis Successfully installed redis-3.0.0 1 gem installed Installing ri documentation for redis-3.0.0... Installing RDoc documentation for redis-3.0.0...

    以前写过一篇ruby on rails的文章，请参考：centos ruby on rails apache mysql 安装配置详解

    喜欢手动编译的人，可以参考这篇文章，安装ruby.

    三，安装redis3.0.0

     

    1，安装redis

    查看复制打印?
  • # wget http://download.redis.io/releases/redis-3.0.0.tar.gz 
  • # tar -xvzf redis-3.0.0.tar.gz 
  • # cd redis-3.0.0 
  • # make && make install 
  • # cd src 
  • # cp redis-trib.rb /usr/local/bin   
  •  
  • # mkdir /etc/redis 
  • # mkdir /var/log/redis 
    • # wget http://download.redis.io/releases/redis-3.0.0.tar.gz # tar -xvzf redis-3.0.0.tar.gz # cd redis-3.0.0 # make && make install # cd src # cp redis-trib.rb /usr/local/bin # mkdir /etc/redis # mkdir /var/log/redis

    上述操作要先在二台机器上面都操作好。

    2,配置redis

    查看复制打印?
  • [root@slave2 redis-3.0.0]#  vim redis.conf   //解压的根目录，有redis.conf,做以下修改 
  • port 6379 
  • pidfile /var/run/redis-6379.pid 
  • dbfilename dump-6379.rdb 
  • appendfilename "appendonly-6379.aof" 
  • cluster-config-file nodes-6379.conf 
  • cluster-enabled yes 
  • cluster-node-timeout 5000 
  • appendonly yes 
    • [root@slave2 redis-3.0.0]# vim redis.conf //解压的根目录，有redis.conf,做以下修改 port 6379 pidfile /var/run/redis-6379.pid dbfilename dump-6379.rdb appendfilename "appendonly-6379.aof" cluster-config-file nodes-6379.conf cluster-enabled yes cluster-node-timeout 5000 appendonly yes

    3，copy配置文件，并修改端口

    查看复制打印?
  • # cp redis.conf /etc/redis/redis-6379.conf 
  • # cp redis.conf /etc/redis/redis-6380.conf 
  • # cp redis.conf /etc/redis/redis-6381.conf 
  •  
  • # scp redis.conf 192.168.10.220:/etc/redis/redis-6382.conf 
  • # scp redis.conf 192.168.10.220:/etc/redis/redis-6383.conf 
  • # scp redis.conf 192.168.10.220:/etc/redis/redis-6384.conf 
  •  
  • # sed -i "s/6379/6380/g" /etc/redis/redis-6380.conf 
  • # sed -i "s/6379/6381/g" /etc/redis/redis-6381.conf 
  •  
  • # sed -i "s/6379/6382/g" /etc/redis/redis-6382.conf 
  • # sed -i "s/6379/6383/g" /etc/redis/redis-6383.conf 
  • # sed -i "s/6379/6384/g" /etc/redis/redis-6384.conf 
    • # cp redis.conf /etc/redis/redis-6379.conf # cp redis.conf /etc/redis/redis-6380.conf # cp redis.conf /etc/redis/redis-6381.conf# scp redis.conf 192.168.10.220:/etc/redis/redis-6382.conf # scp redis.conf 192.168.10.220:/etc/redis/redis-6383.conf # scp redis.conf 192.168.10.220:/etc/redis/redis-6384.conf# sed -i "s/6379/6380/g" /etc/redis/redis-6380.conf # sed -i "s/6379/6381/g" /etc/redis/redis-6381.conf# sed -i "s/6379/6382/g" /etc/redis/redis-6382.conf # sed -i "s/6379/6383/g" /etc/redis/redis-6383.conf # sed -i "s/6379/6384/g" /etc/redis/redis-6384.conf

    将配置文件分别copy到二台机器上，并替换端口：

    查看复制打印?
  • # cat redis-6380.conf |awk '{if($0 !~ /^$/ && $0 !~ /#/) {print $0}}' |grep 6380 
  • pidfile /var/run/redis-6380.pid 
  • port 6380 
  • dbfilename dump-6380.rdb 
  • appendfilename "appendonly-6380.aof" 
  • cluster-config-file nodes-6380.conf 
    • # cat redis-6380.conf |awk '{if($0 !~ /^$/ && $0 !~ /#/) {print $0}}' |grep 6380 pidfile /var/run/redis-6380.pid port 6380 dbfilename dump-6380.rdb appendfilename "appendonly-6380.aof" cluster-config-file nodes-6380.conf

    有5处修改端口的地方

    4，启动并查看redis

    查看复制打印?
  • # redis-server /etc/redis/redis-6379.conf > /var/log/redis/redis-6379.log 2>&1 & 
  • # redis-server /etc/redis/redis-6380.conf > /var/log/redis/redis-6380.log 2>&1 & 
  • # redis-server /etc/redis/redis-6381.conf > /var/log/redis/redis-6381.log 2>&1 & 
  •

  • # redis-server /etc/redis/redis-6383.conf > /var/log/redis/redis-6383.log 2>&1 & 
  • # redis-server /etc/redis/redis-6384.conf > /var/log/redis/redis-6384.log 2>&1 & 
  •  
  • # netstat -tpnl |grep redis

    所有节点都启动成功，并不代表，他们就是集群了。

    四，创建集群，并查看

     

    1，创建redis集群

  • # redis-trib.rb create --replicas 1 192.168.10.219:6379 192.168.10.219:6380 192.168.10.219:6381 192.168.10.220:6382 192.168.10.220:6383 192.168.10.220:6384 
    • # redis-trib.rb create --replicas 1 192.168.10.219:6379 192.168.10.219:6380 192.168.10.219:6381 192.168.10.220:6382 192.168.10.220:6383 192.168.10.220:6384

    2，查看redis集群状态

    查看复制打印?

    到这儿，redis集群就配置成功了

    五，测试redis集群

    查看复制打印?
  • # redis-cli -c -p 6379 -h 192.168.10.219   //在219登录
