部署redis集群

创建网卡

[root@localhost ~]# docker network create redis --subnet 172.38.0.0/16
d87c5b1c0a4283c83c485782823e815b176106800482bdc90ac685b750548316

可以查看下这和网卡的信息

[root@localhost ~]# docker network inspect redis
[
    {
        "Name": "redis",
        "Id": "d87c5b1c0a4283c83c485782823e815b176106800482bdc90ac685b750548316",
        "Created": "2022-01-08T18:13:28.534719317+08:00",
        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": {},
            "Config": [
                {
                    "Subnet": "172.38.0.0/16"
                }
            ]
        },
        "Internal": false,
        "Attachable": false,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },
        "ConfigOnly": false,
        "Containers": {},
        "Options": {},
        "Labels": {}
    }
]

然后通过脚本创建6个redis配置

for port in $(seq 1 6); \
do \
mkdir -p /mydata/redis/node-${port}/conf
touch /mydata/redis/node-${port}/conf/redis.conf
cat << EOF >/mydata/redis/node-${port}/conf/redis.conf
port 6379
bind 0.0.0.0
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 172.38.0.1${port}
cluster-announce-port 6379
cluster-announce-bus-port 16379
appendonly yes
EOF
done

[root@localhost ~]# cd /mydata/
[root@localhost mydata]# ls
redis
[root@localhost mydata]# cd redis
[root@localhost redis]# 
[root@localhost redis]# ls
node-1  node-2  node-3  node-4  node-5  node-6

查看下redis中的配置

[root@localhost redis]# cd node-1
[root@localhost node-1]# ls
conf
[root@localhost node-1]# cd conf
[root@localhost conf]# ls
redis.conf
[root@localhost conf]# cat redis.conf 
port 6379
bind 0.0.0.0
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
clister-announce-ip 172.38.0.11
cluster-announce-port 6379
cluster-announce-bus-port 16379
appendonly yes

运行容器redis1-6：

[root@localhost conf]# docker run -p 6371:6379 -p 16371:16379 --name redis-1 \
     -v /mydata/redis/node-1/data:/data \
     -v /mydata/redis/node-1/conf/redis.conf:/etc/redis/redis.conf \
     -d --net redis --ip 172.38.0.11 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
     
[root@localhost conf]# docker run -p 6372:6379 -p 16372:16379 --name redis-2 \
     -v /mydata/redis/node-2/data:/data \
     -v /mydata/redis/node-2/conf/redis.conf:/etc/redis/redis.conf \
     -d --net redis --ip 172.38.0.12 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

docker run -p 6373:6379 -p 16373:16379 --name redis-3 \
    -v /mydata/redis/node-3/data:/data \
    -v /mydata/redis/node-3/conf/redis.conf:/etc/redis/redis.conf \
    -d --net redis --ip 172.38.0.13 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf
    
     
[root@localhost conf]# docker run -p 6374:6379 -p 16374:16379 --name redis-4 \
     -v /mydata/redis/node-4/data:/data \
     -v /mydata/redis/node-4/conf/redis.conf:/etc/redis/redis.conf \
     -d --net redis --ip 172.38.0.14 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf



     
[root@localhost conf]# docker run -p 6375:6379 -p 16375:16379 --name redis-5 \
     -v /mydata/redis/node-5/data:/data \
     -v /mydata/redis/node-5/conf/redis.conf:/etc/redis/redis.conf \
     -d --net redis --ip 172.38.0.15 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf


[root@localhost conf]# docker run -p 6376:6379 -p 16376:16379 --name redis-6 \
     -v /mydata/redis/node-6/data:/data \
     -v /mydata/redis/node-6/conf/redis.conf:/etc/redis/redis.conf \
     -d --net redis --ip 172.38.0.16 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf

查看下启动的6个容器

全部启动完成

进入redis

[root@localhost conf]# docker exec -it redis-1 /bin/sh
/data # 

创建集群：

redis-cli --cluster create 172.38.0.11:6379 172.38.0.12:6379 172.38.0.13:6379 172.38.0.14:6379 172.38.0.15

/data # redis-cli --cluster create 172.38.0.11:6379 172.38.0.12:6379 172.38.0.13:6379 172.38.0.14:6379 172.38.0.15

yes

启动集群

/data # redis-cli -c               #启动集群
127.0.0.1:6379> cluster info       #查看集群信息

查看下集群的状态 都是可以连上的

测试集群：

127.0.0.1:6379> set a b
-> Redirected to slot [15495] located at 172.38.0.13:6379
OK

存入数据成功 此时断开节点3试一试


发现是从节点4获取到的a的值

redis集群搭建完成！！！

SpringBoot微服务打包Docker镜像

写一个springboot项目打包为jar包

安装一个docker高亮的插件

写一个dockerfile

然后将打包好的jar包和dockerfile上传到linux中

打包为镜像

容器运行成功
