使用 sc-mongodb 进行厨师 MongoDB 复制

Question

我是新来的厨师，我正在使用sc-mongodb，但我无法让它工作。有没有更好的方法来使用 Chef 为 MongoDB 进行复制？

我能够让默认配方正常工作

include_recipe "sc-mongodb::default"

但是当我尝试为 mongo 进行复制时，我开始遇到一些奇怪的错误。

include_recipe "sc-mongodb::replicaset"

错误：

我已经尝试了很多方法来解决这个问题，查看 github 存储库中的 issues。从错误来看，似乎没有设置属性，所以人们手动设置它们。 ：

# attempt1------------

#node.default['mongodb']['config']['replSet'] = true
#node.default[:mongodb][:cluster_name] = "repl-name"
#include_recipe "sc-mongodb::replicaset"

# attempt2----------

#node.normal['mongodb']['install_method'] = 'mongodb-org'
#node.normal['mongodb']['config']['bind_ip'] = '0.0.0.0'
#node.normal['mongodb']['dbconfig_file'] = '/etc/mongod.conf'
#node.normal['mongodb']['config']['replSet'] = true
#node.normal['mongodb']['is_replicaset'] = true
#node.normal['mongodb']['cluster_name'] = 'scribe'
#node.normal['mongodb']['replSet'] = 'scribe'
#node.normal['mongodb']['is_shard'] = false
#include_recipe "sc-mongodb::replicaset"

#attempt3------------
#node.default[:mongodb][:cluster_name] = "cluster_name"
#include_recipe "sc-mongodb::replicaset"

#attempt4------------

#if node['mongodb']['config']['replSet'].nil?
#  node.default['mongodb']['config']['replSet'] = "repl-name"
#end
#include_recipe "sc-mongodb::replicaset"

#attempt5-------------

#https://github.com/sous-chefs/mongodb/issues/167
#node.default['mongodb']['config']['mongod']['replication']['replSetName'] = "rs-name"
#include_recipe "sc-mongodb::replicaset"

这个给了我一个不同的错误：

#attempt6-----------
node.default['mongodb']['config']['mongod']['replication']['replSetName']= 'rs_default'
node.default['mongodb']['cluster_name'] = 'cluster'
node.default['mongodb']['auto_configure']['replicaset'] = true
include_recipe "sc-mongodb::replicaset"

这本食谱给我带来了很多麻烦，你并不孤单。

根据我收集到的信息，您需要多次运行此说明书和/或以不同的配置运行，具体取决于您要达到的目标或节点所处的状态。例如，我认为 auto_configure 属性应该只在其他节点被设置为 false 之后，为集合中的最后一个节点设置。同样对于他们的用户配方，mongodb 只允许在主节点上进行 admin coll 操作，因此您应确保此配方在指定的主节点上执行。

不幸的是，文档不清楚，对于像我这样的 Chef 和 Ruby 新手来说，src 和错误很难解释。我还在整理这本食谱，如果我有具体的东西可以给你报告，你能在你的帖子里完成这个工作吗？抱歉，我无法提供更多帮助，您必须尝试使用​​测试厨房 VM 进行配置。
