在一台机器上搭建redis集群
redis版本3.2；我这也是需要搭建然后网上找文档然最后总结的

参考redis集群搭建(同机器、不同机器搭建)

1,解压源码包安装redis

#安装需要的一些包
yum install ruby rubygems openssl openssl-devel

#此步安装时候，是没有输出的，只要不报错慢慢等待或者更换国内源
#加 -V 参数查看过程
gem install redis --version 3.3.0

#更换国内淘宝源
gem sources --remove https://rubygems.org/
gem sources -a https://gems.ruby-china.com/



#解压安装
tar xf redis-3.2.9.tar.gz
cd redis-3.2.9
make
make install PREFIX=/usr/local/redis #把编译好的redis命令安装到这个目录下面

2，配置redis节点；redis3.x 最少需要6个节点[3主3从的模式]

#配置节点目录
mkdir -p /opt/redis/ && cd /opt/redis
mkdir 7000 7001 7002 7003 7004 7005
cp -rf /usr/local/redis/bin 7000
cp -rf /usr/local/redis/bin 7001
cp -rf /usr/local/redis/bin 7002
cp -rf /usr/local/redis/bin 7003
cp -rf /usr/local/redis/bin 7004
cp -rf /usr/local/redis/bin 7005

#节点配置文件（AOF+RDB持久化方式）
cd /opt/redis/7000
vim redis.conf

bind 192.168.16.186 127.0.0.1 #这里可以多个ip用空格分开
port 7000
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-require-full-coverage no

#aof
appendonly yes
appendfsync everysec
appendfilename "appendonly_7000.aof"
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
no-appendfsync-on-rewrite yes

#rdb
save 900 1
save 300 10
save 60 10000
dbfilename node.rdb
rdbcompression yes
rdbchecksum yes
stop-writes-on-bgsave-error yes
dir ./

pidfile /var/run/redis_7000.pid
logfile /var/log/redis/redis_7000.log

其他几个节点的配置文件和这个一样就行，需要注意需要改动对应端口和一些文件名称

#创建日志目录
mkdir /var/log/redis

#启动各节点
cd /opt/redis/7000 && redis-server ./redis.conf
cd /opt/redis/7001 && redis-server ./redis.conf
cd /opt/redis/7002 && redis-server ./redis.conf
cd /opt/redis/7003 && redis-server ./redis.conf
cd /opt/redis/7004 && redis-server ./redis.conf
cd /opt/redis/7005 && redis-server ./redis.conf

3,创建集群

#进去源码包目录下src目录下面，执行集群创建
cd redis-3.2.9/src/
./redis-trib.rb create --replicas 1 192.168.16.186:7000 192.168.16.186:7001 192.168.16.186:7002 192.168.16.186:7003 192.168.16.186:7004 192.168.16.186:7005

输入 yes

4,连接测试，配置文件里有写127.0.0.1地址，连接时候也可以不用加-h参数

[root@localhost ~]# redis-cli -c -p 7000 -h 192.168.16.186
192.168.16.186:7000> set testkey 123456
OK

5,redis 集群的启动、停止[使用脚本]，如果配置文件中没有监听127.0.0.1地址，就要加上-h ip参数

# 启动脚本
[root@localhost redis]# cat start-redis.sh 
#!/bin/bash
for i in {7000..7005}
do
   cd /opt/redis/$i/
   redis-server ./redis.conf && echo "$i 节点启动成功" || echo "$i 节点启动失败"
done
ps -ef|grep redis


#停止脚本
[root@localhost redis]# cat stop-redis.sh 
#!/bin/bash

function redis_stop(){
  for port in {7000..7005}
  do
    redis-cli -c -p $port $1 && echo "$port 节点已$2" || echo "$port 节点未$2"
  done
}
echo "##### 保存节点数据"
redis_stop save "保存"

echo "##### 停止节点"
redis_stop shutdown "停止"

2台机器搭建集群；每台3个节点；配置大同小异这里就不在贴出过程了

1，同样道理安装不变，配置节点每台为3个就行，2台机器6个节点即可；端口一样不一样都可以
2，配置文件bind的IP地址修改，两台机器要互通
3，创建集群时在2台机器任意一台即可，注意节点地址和端口的变化
