redis集群

本文主要是介绍redis集群，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

端口号分别为：7001~7006
mkdir redis-cluster/7001
make install PREFIX=/var/redis-cluster/7001
cp /var/redis-5.0.5/redis.conf /var/redis-cluster/7001/bin

port 7001
daemonize yes
cluster-enable yes
protected-mode no
#bind 127

cp -r /var/redis-cluster/7001/* /var/redis-cluster/7002
cp -r /var/redis-cluster/7001/* /var/redis-cluster/7003
cp -r /var/redis-cluster/7001/* /var/redis-cluster/7004
cp -r /var/redis-cluster/7001/* /var/redis-cluster/7005
cp -r /var/redis-cluster/7001/* /var/redis-cluster/7006

改port

创建start.sh，

cd 7001/bin
./redis-server redis.conf
cd …
cd …
cd 7002/bin
./redis-server redis.conf
cd …
cd …
cd 7003/bin
./redis-server redis.conf
cd …
cd …
cd 7004/bin
./redis-server redis.conf
cd …
cd …
cd 7005/bin
./redis-server redis.conf
cd …
cd …
cd 7006/bin
./redis-server redis.conf
cd …
cd …

chmod u+x start.sh

./start.sh

创建Redis集群
./redis-cli --cluster create 192.168.1.7:7001 192.168.1.7:7002 192.168.1.7:7003 192.168.1.7:7004 192.168.1.7:7005 192.168.1.7:7006 --cluster-replicas 1

添加主节点
mkdir redis-cluster/7007
make install PREFIX=/var/redis-cluster/7007
cp /var/redis-5.0.5/redis.conf /var/redis-cluster/7007/bin

port7007
daemonize yes
cluster-enable yes
protected-mode no
#bind 127

cp -r 7007 7008
port 7008

./redis-cli --cluster add-node 192.168.1.7:7007 192.168.1.7:7001

hash槽重新分配（数据迁移）
./redis-cli --cluster reshard 192.168.1.7:7007

添加从节点
./redis-cli --cluster add-node 192.168.1.7:7008 192.168.1.7:7007 --cluster-slave --cluster-master-id 388334154ba308f85b7dfbd8d228e35dfcf35832
