NoMatchingDocument:在local.system.replset中找不到副本集配置文档

Question

我在我的AWS EC2实例中有一个独立的MongoDB实例。我打算把它换成Mongo Atlas。前提条件是将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

我使用下面的命令来创建副本集：

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

我得到以下错误：

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

我还应该在mongo.conf文件中更改哪些内容？

我也有同样的问题，但我解决了以下步骤：

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

所以我将Mongo shell交换机连接到本地。

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

我正在使用bitnami/mongodb helm chart将mongodb部署到我们的自定义k8s集群，因为在默认情况下它是cluster.local，并且导致在主机地址中使用错误的集群域运行mongodb，所以忘记覆盖values.yaml文件中的clusterDomain变量时会出现这个错误：

mongodb 14:59:37.35 WARN ==> Problem initiating replica set
