这适用于带有Mongoid的Rails 5应用程序。
显然mongoid.yml还可以。它适用于其他系统(例如OSX 10.11.6)。
test:
clients:
default:
database: interview_test
hosts:
- localhost:27017
当我的应用尝试连接时,我得到:
Mongo::Error::NoServerAvailable:
No server is available matching preference: #<Mongo::ServerSelector::Primary:0x70244985573080 tag_sets=[] max_staleness=nil> using server_selection_timeout=30 and local_threshold=0.015
经过多次搜索,我发现以下mongoid.yml 确实有效 :
hosts:
- 127.0.0.1:27017
这是/ etc / hosts:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
为什么localhost
不适用于High Sierra?怎么解决?
