我正在尝试为kafka连接器和cassandra集群3示例设置landoop/fast data dev cluster,但得到“启动userland proxy:listen tcp 0.0.0.0:9042:bind:address already in use”的错误消息。
sudo netstat -pna | grep 9042 我得到: tcp 0 0 127.0.0.1:9042 0.0.0.0:* LISTEN 1166/java 我试过了 pkill -f CassandraDaemon 以及 docker rm -f $(docker ps -aq) 没有成功。以下是docker compose文件:

version: '2'

在端口9042上运行了其他程序,如您所示:

sudo netstat -pna | grep 9042

tcp        0      0 127.0.0.1:9042          0.0.0.0:*               LISTEN      1166/java

这就是为什么你不能启动docker容器,它也想使用同一个端口。
问题是,你假设它一定是 Docker 或Cassandra在那个港口,并试图杀死他们

pkill -f CassandraDaemon
docker rm -f $(docker ps -aq)

你真正需要做的是找出 1166 或者如果它应该运行,为docker容器选择一个不同的端口来使用

ps -ef|grep 1166
