Restoring the dds mongos Node

Procedure

  1. Prepare the configuration file and directory of the dds mongos node.

    rm -rf /compile/cluster-restore/mgs*

    mkdir -p /compile/cluster-restore/mgs1/log

    mkdir -p /compile/cluster-restore/mgs2/log

  2. Configuration file (restoreconfig/mongos_40301.yaml) 

    net:
  bindIp: 127.0.0.1 
  port: 40301
  unixDomainSocket: {enabled: false}
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/mgs1/mongos.pid}
sharding: {configDB: 'config/127.0.0.1:40303,127.0.0.1:40304,127.0.0.1:40305'}
systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/mgs1/log/mongos.log}

  3. Configuration file (restoreconfig/mongos_40302.yaml) 

    net:
  bindIp: 127.0.0.1 
  port: 40302
  unixDomainSocket: {enabled: false}
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/mgs2/mongos.pid}
sharding: {configDB: 'config/127.0.0.1:40303,127.0.0.1:40304,127.0.0.1:40305'}
systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/mgs2/log/mongos.log}

  4. Start the mongo node.

    ./mongos -f restoreconfig/mongos_40301.yaml

    ./mongos -f restoreconfig/mongos_40302.yaml

Checking the Cluster Status

Connect to the cluster through dds mongos and check the data status.

./mongo --host 127.0.0.1 --port 40301

./mongo --host 127.0.0.1 --port 40302
