# ***redis 5.0.4******集群搭建*** #

### *step0* *简介* ###

redis 集群搭建指南

模式: 三主三从

redis 版本: redis 5.0.4

5.0版本后不需要ruby支持，其底层改由C实现

主从配置、leader选举由redis自己实现

操作系统: centos 7.x

192.168.1.240:6379  192.168.1.240:6380

192.168.1.241:6379  192.168.1.241:6380

192.168.1.242:6379  192.168.1.242:6380

### *Step1* *环境安装* ###

环境需要:

安装 gcc 、tcl(8.5版本以上)，可以 yum安装

### *Step2* *编译安装* ###

解压到 /user/local

编译: make MALLOC=libc

安装: make install

### *Step3* *修改配置文件* ###

修改配置文件（每个实列）

1）daemonize yes   //后台启动哟

2）port 6379（分别对每个机器的端口号进行设置）

3）dir /usr/local/redis-data/6379/（指定数据文件存放位置，必须要指定不同的目录位置，不然会丢失数据）

4）cluster-enabled yes（启动集群模式）

5）cluster-config-file nodes-6379.conf（集群节点信息文件，这里63xx最好和port对应上）

6）cluster-node-timeout 5000

\#bind 127.0.0.1（去掉bind绑定访问ip信息）

protected-mode  no   （关闭保护模式）

9）appendonly yes

### *Step4* *启动实例* ###

启动每个机器上的redis实例

/usr/local/redis-5.0.4/src/redis-server  /etc/redis-cluster/6379/redis-6379.conf

/usr/local/redis-5.0.4/src/redis-server  /etc/redis-cluster/6380/redis-6380.conf

### *Step5* *配置集群* ###

/usr/local/redis-5.0.4/src/redis-cli  --cluster create --cluster-replicas 1 192.168.1.240:6379  192.168.1.240:6380  192.168.1.241:6379  192.168.1.241:6380  192.168.1.242:6379  192.168.1.242:6380

集群配置日志信息如下:
