1、创建网络 代码语言： javascript
复制 [root@iZ2zeir6vcnpz8qw3t455tZ ~]# docker network create redis --subnet 172.38.0.0/16
4323026b1d7145e167f22ecc0e908dfe0d75765380840e29e6b7010f1b3b902c
[root@iZ2zeir6vcnpz8qw3t455tZ ~]# docker network ls

]2、编写配置文件 代码语言： javascript
复制 forport 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-announce-ip 172.38.0.1${port}
cluster-announce-port 6379
cluster-announce-bus-port 16379
appendonly yes
EOF
done3、创建容器 代码语言： javascript
