redis集群代建

1:解压redis目录到 /usr/local 目录下

2:  ps -ef|grep redis  查看有没有redis进程,有的话关闭redis

 3:搭建集群准备  (三主三从,伪集群)

 3.1   进入    cd /usr/local/

 3.2   mkdir redis_cluster

 3.3    cd redis_cluster    

4: 拷贝 redis 文件    

cp /usr/local/redis-4.0.6/redis.conf /usr/local/redis_cluster/7000 

 

5:进入 /usr/local/redis_cluster/7000  修改 redis,conf 文件. 输入 / 查询  小写 n 下一个

cluster-enabled yes    //去掉注释,改成集群模式

 

cluster-config-file nodes.conf //集群的配置 配置?件?次启动?动?成

 

cluster-node-timeout 5000 //请求超时 设置5秒够了

 

appendonly yes   //aof?志开启 有需要就开启，它会每次写操作都记录?条?志

 

bind 127.0.0.1 172.16.244.144(此处为??内?的ip地址，centos7下?采?ip addr来查看，

其他系统试?下ifconfig查看，ip为)

 

 

6:修改完后 wq 保存  输入   cd ../7001

 

复制到其他文件

cp /usr/local/redis_cluster/7000/redis.conf /usr/local/redis_cluster/7001

cp /usr/local/redis_cluster/7000/redis.conf /usr/local/redis_cluster/7002

cp /usr/local/redis_cluster/7000/redis.conf /usr/local/redis_cluster/7003

cp /usr/local/redis_cluster/7000/redis.conf /usr/local/redis_cluster/7004

cp /usr/local/redis_cluster/7000/redis.conf /usr/local/redis_cluster/7005

 

各自修改端口号

修改完成后  输入

cp /usr/local/redis-4.0.6/src/redis-server /usr/local/redis_cluster   拷贝文件

7: 进入每个目录启动redis

cd /usr/local/redis_cluster/7000

 

../redis-server ./redis.conf

 

 

cd /usr/local/redis-cluster/7001

 

 

../redis-server ./redis.conf

 

 

cd /usr/local/redis-cluster/7002

 

 

../redis-server ./redis.conf

 

 

cd /usr/local/redis-cluster/7003

../redis-server ./redis.conf

 

 

cd /usr/local/redis-cluster/7004

../redis-server ./redis.conf

 

 

cd /usr/local/redis-cluster/7005

../redis-server ./redis.conf

 

每个节点启动成功

8:安装ruby

yum -y install ruby ruby-devel rubygems rpm-build 

 

编译

 gem install redis

 

 

 

9:进入  

cd /usr/local/redis-4.0.6/src

 

启动集群 

./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 \127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

 

10:  测试集群是否正常

 

  ./redis-cli -p 7000 shutdown   关闭redis
