Docker 搭建redis集群

六个Redis实例的配置文件：
redis.conf

port 7000
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes

/opt/redis
		/7000/redis.conf
		/7001/redis.conf
		/7002/redis.conf
		/7003/redis.conf
		/7004/redis.conf
		/7005/redis.conf

mkdir /opt/redis
cd /opt/redis
mkdir 7000 7001 7002 7003 7004 7005

cat <<EOF >7000/redis.conf
port 7000
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
EOF

cat <<EOF >7001/redis.conf
port 7001
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
EOF

cat <<EOF >7002/redis.conf
port 7002
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
EOF

cat <<EOF >7003/redis.conf
port 7003
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
EOF

cat <<EOF >7004/redis.conf
port 7004
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
EOF

cat <<EOF >7005/redis.conf
port 7005
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
EOF

先启动6个redis实例

docker run -d --name redis7000 \\
-v /opt/redis/7000/redis.conf:/redis.conf \\
--net=host \\
--restart=always \\
redis \\
redis-server /redis.conf

docker run -d --name redis7001 \\
-v /opt/redis/7001/redis.conf:/redis.conf \\
--net=host \\
--restart=always \\
redis \\
redis-server /redis.conf

docker run -d --name redis7002 \\
-v /opt/redis/7002/redis.conf:/redis.conf \\
--net=host \\
--restart=always \\
redis \\
redis-server /redis.conf

docker run -d --name redis7003 \\
-v /opt/redis/7003/redis.conf:/redis.conf \\
--net=host \\
--restart=always \\
redis \\
redis-server /redis.conf

docker run -d --name redis7004 \\
-v /opt/redis/7004/redis.conf:/redis.conf \\
--net=host \\
--restart=always \\
redis \\
redis-server /redis.conf

docker run -d --name redis7005 \\
-v /opt/redis/7005/redis.conf:/redis.conf \\
--net=host \\
--restart=always \\
redis \\
redis-server /redis.conf

执行命令配置集群

# 进入容器执行集群配置命令

docker exec -it redis7000 \\
redis-cli --cluster create \\
192.168.64.150:7000 192.168.64.150:7001 \\
192.168.64.150:7002 192.168.64.150:7003 \\
192.168.64.150:7004 192.168.64.150:7005 \\
--cluster-replicas 1

查看集群信息

docker exec -it redis7000 redis-cli -c -p 7000

cluster info

cluster nodes

存数据

docker exec -it redis7000 redis-cli -c -p 7000
# 7002
set a aaaaaaaaaaaaa
# 7000
set b bbbbbbbbbbb
# 7001
set c cccccccccccccccc
