cassandra 安装_cassandra.noarch.0.4.1.3-1 将被 安装 错误:invalid versio

# 获取镜像
docker pull cassandra
# 运行
docker run -d --name cassandra cassandra:latest -p 9402:9402
# 进入容器
docker exec -it cassandra bash
 
# 更新apt-get 并安装vim
apt-get update
 
apt-get install vim -y
 
# 进入数据库
cqlsh
# 修改集群名称
UPDATE system.local SET cluster_name = 'cass_cluster' where key='local';
 
# 修改完成,退出
exit
# 修改配置文件
vim /etc/cassandra/cassandra.yaml
 
# 集群名称
cluster_name:cass_cluster
# 修改集群ip
seeds: "127.0.0.1,127.0.0.2,127.0.0.3"
 
保存退出重启容器
docker restart cassandra

创建集群失败 , docker集群跑不起来 , 最后使用yum 方式安装集群启动成功
