centos 7 redis cluster 搭建

1.安装路径:
/usr/redis

2.准备工作:

yum install gcc

make && make install

3.每个节点需要做的配置:

daemonize yes //redis后台运行
pidfile /var/run/redis_7000.pid //pidfile文件对应7001,7002,7003,7004,7005,7006
port 7000 //端口7001,7002,7003,7004,7005,7006
cluster-enabled yes //开启集群 把注释#去掉
cluster-config-file nodes_7000.conf //集群的配置 配置文件首次启动自动生成 7001,7002,7003,7004,7005,7006
cluster-node-timeout 5000 //请求超时 设置5秒够了
appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志

4.启动每个节点
redis-server ../7001/redis.conf
redis-server ../7002/redis.conf
redis-server ../7003/redis.conf
redis-server ../7004/redis.conf
redis-server ../7005/redis.conf
redis-server ../7006/redis.conf

OR

for (( i=1; i<=6; i++ )) do redis-server ../../700$i/redis.conf; done;

ps -ef | grep redis #查看是否启动成功
netstat -tnlp | grep redis #可以看到redis监听端口

5.创建集群:
安装ruby 和 gem
yum -y install ruby ruby-devel rubygems rpm-build

修改gem国内镜像:
gem sources --remove https://rubygems.org/
gem sources -a https://ruby.taobao.org/

安装redis接口
gem install redis

解决: 
gem install redis时
ERROR: Error installing redis: redis requires Ruby version >= 2.2.2.
------------------------------------------------------------------

• gpg2 --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3
• curl -L get.rvm.io | bash -s stable
• find / -name rvm -print
• source /usr/local/rvm/scripts/rvm
• rvm list known
• rvm install 2.3.3
• rvm use 2.3.3 --default
• rvm remove 2.0.0
• ruby --version

6.创建结群:

• 创建之前,防火墙先要开放相应的端口,不然会报错
  • firewall-cmd --add-port=7001/tcp --permanent
• 创建集群:
• ./redis-trib.rb create --replicas 1 192.168.100.21:7001 192.168.100.21:7002 192.168.100.21:7003 192.168.100.21:7004 192.168.100.21:7005 192.168.100.21:7006

 

• 验证集群:
  • redis-cli -h 192.168.100.21 -c -p 7002

• • set name 123

• • get name

 

• 连接其他节点,可以找到同步的数据

 

7. 关闭集群:

• pkill -9 redis
