我通过带有 postgresql 的 Vagrant 虚拟机制作并希望将其用作我的 Rails 应用程序数据库。
我使用类似的 Vagrantfile:
Vagrant.configure("2") do |config|
config.vm.network :private_network, ip: "192.168.33.18"
config.vm.provision :chef_solo do |chef|
# I take cookbook from https://github.com/opscode-cookbooks/postgresql
chef.add_recipe "postgresql::server"
chef.json = {
postgresql: {
config: {
ssl: false,
listen_addresses: '*'
},
password: {
postgres: 'postgres'
}
}
}
end
end
接下来我vagrant up
并期望下一个database.yml
将起作用:
development:
database: app_development
adapter: postgresql
host: '192.168.33.18'
username: root
但这不会发生.. Rake 任务失败并出现错误:
could not connect to server: Connection refused
Is the server running on host "192.168.33.18" and accepting
TCP/IP connections on port 5432?
我看到那个端口实际上没有打开
$ nmap -p 5432 192.168.33.18
Starting Nmap 6.25 ( http://nmap.org ) at 2013-05-07 22:05 FET
Nmap scan report for 192.168.33.18
Host is up (0.00047s latency).
PORT STATE SERVICE
5432/tcp closed postgresql
而且我可以在vm上看到一些postgres进程,并且vagrant输出没有任何错误,所以我相信postgres可以正常工作。
932 postgres 20 0 126m 9.9m 8916 S 0 2.7 0:00.03
postgres
941 postgres 20 0 97460 1348 192 S 0 0.4 0:00.00 postgres
944 postgres 20 0 126m 1728 548 S 0 0.5 0:00.06 postgres
945 postgres 20 0 126m 1488 316 S 0 0.4 0:00.05 postgres
946 postgres 20 0 126m 2768 1000 S 0 0.7 0:00.00 postgres
947 postgres 20 0 97456 1584 352 S 0 0.4 0:00.00 postgres
如何在我的 Rails 应用程序中设置 Vagrant 以在虚拟机上使用 db?
更新我的pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all peer
###########
# Other authentication configurations taken from chef node defaults:
###########
local all all trust
host all all 0.0.0.0/0 md5
