redis4伪集群搭建

# [redis4集群][redis4] #

三台服务器：先设置hosts
    10.0.0.231  node1
    10.0.0.232  node2
    10.0.0.233  node3

端口分配：
    node1:7000 
    node1:7001  
    node2:7002  
    node2:7003  
    node3:7004  
    node3:7005

1：下载redis-4.0.1并解压

解压目录：/usr/local/redis-4.0.1
    建立软连接：ln -s redis-4.0.1 redis

2：编译安装

指定安装目录到:/usr/local/redis
    
    make && make install PREFIX=/usr/local/redis

3：创建配制节点

![复制代码][copycode.gif]

node1服务器:
    mkdir -p /usr/loca/redis/redis_cluster/7000
    mkdir -p /usr/loca/redis/redis_cluster/7001
    
    cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7000
    cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7001
    
    node2服务器:
    mkdir -p /usr/loca/redis/redis_cluster/7002
    mkdir -p /usr/loca/redis/redis_cluster/7003
    
    cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7002
    cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7003
    
    node3服务器:
    mkdir -p /usr/loca/redis/redis_cluster/7004
    mkdir -p /usr/loca/redis/redis_cluster/7005
    
    cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7004
    cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7005

4：修改redis.conf

![复制代码][copycode.gif]

切记：不能设置密码，否则集群启动时会连接不上
    
    port  7000                                //端口根据对应的文件夹去配制端口 7000,7001,7002,7003,7004,7005      
    bind 本机ip                               //根据本机所在的IP或hostname去配制 node1 node2 node3
    daemonize    yes                          //redis后台运行
    pidfile  /var/run/redis_7000.pid          //pidfile文件对应7000,7001,7002,7003,7004,7005
    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 7000,7001,7002,7003,7004,7005
    cluster-node-timeout  15000               //请求超时  默认15秒，可自行设置
    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

5：复制src目录中的redis-trib.rb 到/usr/local/redis/bin目录

cp  /usr/local/redis/redis-trib.rb /usr/local/redis/bin

6：安装ruby环境

yum install -y ruby
    yum install -y rubygems

7：安装ruby的包

![复制代码][copycode.gif]

gem install redis-4.0.0.rc1.gem
    
    如果不成功需要去下载后安装
    下载地址
    https://rubygems.org/gems/redis/versions/4.0.0.rc1
    https://rubygems.org/downloads/redis-4.0.0.rc1.gem
    
    安装命令：gem install -l ./redis-4.0.0.rc1.gem

8：启动各个节点

![复制代码][copycode.gif]

node1服务器:
    /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7000/redis.conf
    /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7001/redis.conf
    
    node2服务器:
    /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7002/redis.conf
    /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7003/redis.conf
    
    node3服务器:
    /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7004/redis.conf
    /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7005/redis.conf

![复制代码][copycode.gif]

9：检查各节点是否启动

查看进程
    ps -ef | grep redis
    
    查看端口
    netstat -tnlp | grep redis

10：创建集群

进入node1的bin目录下,执行以下脚本
    ./redis-trib.rb  create  --replicas  1  node1:7000 node1:7001  node2:7002  node2:7003  node3:7004  node3:7005

11：验证集群

![复制代码][copycode.gif]

进入每台服务器的redis/src目录,记住参数  -c不可以少
    
    redis-cli -h node1 -p 7000 -c
    
    redis-cli -h node2 -p 7002 -c

redis\-cli -h node3 -p 7004 \-c
