Redis 创建和使用集群

服务器架构

192.168.188.136   192.168.188.137

下载Redis（两台服务器均需要操作）

【1】环境准备

yum -y install gcc automake autoconf libtool make

【2】下载解压

cd /home/
wget http://download.redis.io/releases/redis-5.0.3.tar.gz
tar xzf redis-5.0.3.tar.gz

【3】编译

cd redis-5.0.3
make MALLOC=libc　　　

【4】开放端口或关闭防火墙

service iptables stop

创建集群节点（两台服务器均需要操作）

【1】创建集群节点目录

mkdir /home/redis-cluster
mkdir /home/redis-cluster/7000 /home/redis-cluster/7001 /home/redis-cluster/7002

【2】修改redis默认的配置文件

vim /home/redis-5.0.3/redis.conf

port 7000
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
bind Server_IP（192.168.188.136 / 192.168.188.137） 127.0.0.1

【3】复制redis-server & redis.conf

cp -a /home/redis-5.0.3/src/redis-server /home/redis-cluster/

cp -a /home/redis-5.0.3/redis.conf /home/redis-cluster/7000/; \
cp -a /home/redis-5.0.3/redis.conf /home/redis-cluster/7001/; \
cp -a /home/redis-5.0.3/redis.conf /home/redis-cluster/7002/;

【4】修改端口号 & 启动redis服务

　　<7000>

cd /home/redis-cluster/7000/
../redis-server ./redis.conf

　　<7001>

# port 7001
cd ../7001/; vim redis.conf
../redis-server ./redis.conf

　　<7002>

# port 7002
cd ../7002/; vim redis.conf
../redis-server ./redis.conf 

【5】查看节点启动状态

netstat -tunlp | grep redis

创建集群添加集群节点（192.168.188.136服务器）

cd /home/redis-5.0.3/src/

./redis-cli --cluster create 192.168.188.136:7000 192.168.188.136:7001 192.168.188.136:7002 \
192.168.188.137:7000 192.168.188.137:7001 192.168.188.137:7002 \
--cluster-replicas 1

192.168.188.136:7000> exit

【2】192.168.188.137服务器操作

cd /home/redis-5.0.3/src

./redis-cli -c -h 192.168.188.137 -p 7000
192.168.188.137:7000> get hello
-> Redirected to slot [866] located at 192.168.188.136:7000

./redis-cli -c -h 192.168.188.137 -p 7001
192.168.188.137:7001> set age 18
-> Redirected to slot [741] located at 192.168.188.136:7000
