$ curl 'http://localhost:8123/'
curl: (7) Failed to connect to localhost port 8123: Connection refused

请帮我解决这个问题。

Answer 1

UPD

如果您不想更改网络类型，一个好的解决方案是将容器的端口发布到主机。可以使用 -p HOST_PORT:CONTAINER_PORT 参数来完成。在您的情况下，它将是 -p 8123:8123。一个例子： docker run -d --name clickhouse-server --ulimit nofile=262144:262144 -p 8123:8123 yandex/clickhouse-server

原回答

似乎有一个 docker 容器连接到您无法从您的主机访问的网络。尝试启动带有 --net=host 标志的图像。然后，运行又是curl。

有关 docker 网络类型及其功能的其他信息，请参见 official documentation

Answer 2

首先检查你的 clickhouse-server 是否正确运行ning 或者没有使用这个命令：

sudo lsof -i :8123

您应该能够看到类似的输出：

COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

clickhous 8752 root    9u  IPv6  38265      0t0  TCP ip6-localhost:8123 (LISTEN)

clickhous 8752 root   12u  IPv4  38268      0t0  TCP localhost:8123 (LISTEN)

确保位于 /etc/clickhouse-server

的 config.xml 文件中包含这些条目

<listen_host>::1</listen_host>
<!-- Localhost Binding -->
<listen_host>127.0.0.1</listen_host>
<!-- Remote Access Binding -->
<listen_host>< IP / URL></listen_host>

一旦您确定这些条目存在，运行这些命令将重新启动您的服务器：

cd /usr/bin
sudo ./clickhouse-server --config /etc/clickhouse-server/config.xml &

再次执行 sudo lsof -i :8123 以查看您的 clickhouse-server 是否正在监听该端口。
