maxcrtl无法连接到maxscale。
我有一个k8s集群，我想在这个集群上部署MariaDB集群。我有主舱和奴隶舱，想用最大比例监视它们。pod以其默认配置运行，没有任何问题，但是当我在configmap类型中挂载卷并运行maxctrl list servers时，会得到以下错误：
Error: Could not connect to MaxScale吊舱的原木：

我使用maxscale默认配置，但是当我将它挂载到/etc/maxscale.cnf.d时，它不起作用，所以我认为问题与读取配置文件有关。

确保在运行maxscale进程的同一个容器中运行命令:默认情况下，它只侦听端口8989上的本地连接。如果希望MaxScale侦听所有接口，而不仅仅是循环接口，请使用admin_host=0.0.0.0。
如果您公开容器的REST端口并希望从外部连接到它，请使用maxctrl -h address:port。address是网络地址(admin_host in maxscale.cnf)，port是它侦听的网络端口(admin_port in maxctrl.cnf)。
例如，在MaxScale上连接到mxshost容器

我找到了答案。它是关于maxscale配置中的冲突。我在maxscale.cnf中添加了一个新的配置，并将其挂载到/etc/maxscale.cnf.d/。但是，我认为这个配置被追加到/etc/maxscale.cnf，所以当我在/etc/maxScale.cnf中再次包含以下部分时，它会产生冲突：
[maxscale]
threads=auto
admin_enabled=false所以我从我的configmap中删除了这个部分，它起了作用。
