无法在vagrant上获取Cassandra远程访问 [英] Can't get Cassandra remote access on vagrant
问题描述
我使用vagrant / puppet来配置带有Apache Cassandra的虚拟机。本地访问(通过 cqlsh
)可以正常工作,但不能远程访问。
I am using vagrant/puppet to configure a VM with Apache Cassandra. Local access (via cqlsh
) works, but not remote access.
Vagrantfile
Here is my Vagrantfile
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.box = 'ubuntu/trusty32'
config.vm.define "dev" do |dev|
dev.vm.hostname = "devbox"
dev.vm.network :private_network, ip: "192.168.10.200"
end
config.vm.provision "puppet" do |puppet|
puppet.module_path = "puppet/modules"
puppet.manifests_path = "puppet/manifests"
puppet.manifest_file = "default.pp"
end
config.vm.provider "virtualbox" do |v|
v.memory = 4096
v.cpus = 2
end
config.ssh.forward_agent = true
end
我可以告诉你我的木偶文件,但我认为分享cassandra.yaml会更容易/
I could show you my puppet file, but I think it would be easier/clearer to share the cassandra.yaml it generated.

在方块...
vagrant@devbox:~$ cqlsh
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})
vagrant@devbox:~$ cqlsh 192.168.10.200
Connected to Test Cluster at 192.168.10.200:9042.

从我的主机(Windows),我可以ping虚拟。
From my host machine (Windows), I can ping the virtual.

我尝试访问这个Cassandra实例在我的.NET项目(在主机上)使用以下代码...
But when I try to access this Cassandra instance in my .NET project (on host) using the following code...
var cluster = Cluster.Builder().AddContactPoint("192.168.10.200").Build();
var session = cluster.Connect("test");
..我得到这个异常。
..I get this exception.
An exception of type 'Cassandra.NoHostAvailableException' occurred in Cassandra.dll but was not handled in user code
Additional information: None of the hosts tried for query are available (tried: 192.168.10.200:9042)
是什么?
UPDATE
我从头开始,创建一个空的vagrant vm(无配置)并手动安装Cassandra。同样的事情发生了。但是,当我从一个private_network切换到一个具有桥接/ DHCP的public_network时,它工作。
I started over from scratch, creating an empty vagrant vm (no provisioning) and manually installed Cassandra. The same thing is happening. However, when I switched from a "private_network" to a "public_network" with bridged/DHCP, it worked.
我想说的端口没有打开private_network,但我已经安装了其他服务(RabbitMQ / Postgres),他们工作出了一个问题。那么,为什么Cassandra不使用private_network?
I want to say that the ports aren't open with "private_network", but I have installed other services (RabbitMQ/Postgres) and they work with out an issue. So, why is Cassandra not working with the "private_network"?
推荐答案
确保您的 Vagrantfile
正在使用
private_network
,如:
config.vm.network "private_network", ip: "192.168.33.10"
请注意, code> vagrant ssh 您在提示之前会看到一些信息,包括:
Notice that when you use vagrant ssh
you are shown some info prior the prompt which includes:
IP address for eth1: 192.168.33.10
编辑您的 / etc / cassandra / cassandra .yml
文件(行〜482/483)为:
Edit your /etc/cassandra/cassandra.yml
file (lines ~482/483) to be:
# rpc_address: localhost
rpc_interface: eth1
ie注释掉 rpc_address
,而是指定由vagrant指定的 rpc_interface
,则:
i.e. comment out the rpc_address
and instead specify the rpc_interface
as given by vagrant, then:
sudo service cassandra restart
