docker-compose配置redis集群-支持arm

创建文件夹

在 /usr/local/docker/下创建，方便管理

mkdir redis-cluster

# 创建redis-1~redis-6文件夹

mkdir redis-cluster/redis-1 \
redis-cluster/redis-2 \
redis-cluster/redis-3 \
redis-cluster/redis-4 \
redis-cluster/redis-5 \
redis-cluster/redis-6

新建配置文件

cd redis-cluster

cat > redis-1/redis.conf << EOF
protected-mode no
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
port 6381
masterauth 123456
requirepass 123456
EOF
cat > redis-2/redis.conf << EOF
protected-mode no
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
port 6382
masterauth 123456

cat > redis-3/redis.conf << EOF

docker-compose.yaml文件配置 (复制有问题可以用 cat > docker-compose.yaml << EOF)

cd redis-cluster

cat > docker-compose.yaml << EOF

启动容器

docker-compose up -d

 查看启动状态确保up

docker ps

创建集群（执行完会提示输入yes）

docker exec -it redis-1 redis-cli --cluster create 10.211.55.7:6381 10.211.55.7:6382 10.211.55.7:6383 10.211.55.7:6384 10.211.55.7:6385 10.211.55.7:6386 --cluster-replicas 1
#下边这个不用执行
docker exec -it redis-1 redis-cli --cluster  create  -a 123456 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384 127.0.0.1:6385 127.0.0.1:6386 --cluster-replicas 1

连接redis-1节点并查看集群信息节点信息

docker exec -it redis-1 redis-cli -c -h 10.211.55.7 -p 6381 -a 123456
cluster info
cluster nodes

使用set和get命令测试（set会自动到某个节点切片get也会在该切片上获取，但连接点不变）

set name grant
get name

设置密码(已在配置文件中添加)

在redis.conf中添加
masterauth 123456 
requirepass 123456
在dockerfile中添加
environment: 
  - REDISCLI_AUTH=123456

认证连接

redis-cli -c -h 10.211.55.7 -p 6381 -a 123456

使用rdm连接单个

 

 

查看正在连接redis的进程

ps -ef | grep redis

有问题可以删除 

docker stop redis-1 redis-2 redis-3 redis-4 redis-5 redis-6

docker rm redis-1 redis-2 redis-3 redis-4 redis-5 redis-6


ps -ef |grep redis
