NoMatchingDocument：在local.system.replset中没有找到副本集配置文档

Question

我的 AWS EC2 实例中有一个独立的 MongoDB 实例。 我打算将其转移到 Mongo Atlas。 前提是将 MongoDB 实例转换为副本集。

下面是我的mongo.conf文件的代码：

# mongodb.conf

# Where to store the data.
dbpath=/opt/bitnami/mongodb/data/db

#where to log
logpath=/opt/bitnami/mongodb/log/mongodb.log

logappend=true

bind_ip = 127.0.0.1
port = 27017

# Enable journaling, http://www.mongodb.org/display/DOCS/Journaling
journal=true


# Enable smaller default file size for MongoDB
# Also reduces size of journal files from 1G to 128M
#smallfiles=true

# Enables periodic logging of CPU utilization and I/O wait
#cpu = true

# Turn on/off security.  Off is currently the default
#noauth = true
auth = true

# Verbose logging output.
#verbose = true

# Inspect all client data for validity on receipt (useful for
# developing drivers)
#objcheck = true

# Enable db quota management
#quota = true

# Set oplogging level where n is
#   0=off (default)
#   1=W
#   2=R
#   3=both
#   7=W+some reads
#oplog = 0

# Diagnostic/debugging option
#nocursors = true

# Ignore query hints
#nohints = true



setParameter = enableLocalhostAuthBypass=0


unixSocketPrefix=/opt/bitnami/mongodb/tmp
fork = true

setParameter = enableLocalhostAuthBypass=0




# Replication Options

replication:
    replSetName: res0

# in replicated mongo databases, specify here whether this is a slave or master
#slave = true
#source = master.example.com
# Slave only: specify a single database to replicate
#only = master.example.com
# or
#master = true
#source = slave.example.com

我正在使用以下命令创建副本集：

 sudo mongod --port 27017 --dbpath /opt/bitnami/mongodb --replSet res0 --bind_ip localhost

我收到以下错误：

NoMatchingDocument: Did not find replica set configuration document in local.system.replset

我还应该在我的mongo.conf文件中更改什么？

Answer 1

我有同样的问题，但我按照以下步骤解决了：

我在 Windows 服务器上。 Mongo DB shell 版本 3.0.4。 以下屏幕截图中的错误与您提到的相同

所以我连接到 Mongo shell 切换到本地。

使用以下命令。 请注意 SIR 是我的副本集名称

    cfg = {  _id:"SIR" , members:
                 [{ _id:0,host:"localhost:27017"}] 
    
           };

   rs.initiate(cfg)

结果

Answer 2

我正在使用bitnami/mongodb helm chart 将 mongodb 部署到我们的自定义 k8s 集群，并在忘记覆盖我的values.yaml文件中的clusterDomain变量时出现此错误，因为默认情况下它是cluster.local并导致运行rs.initiate eval主机地址中的错误集群域：
