操作步驟

步驟 1 準備單(dan)(dan)節(jie)點配置文件和(he)目錄，以單(dan)(dan)節(jie)點方式啟動進(jin)程。

配置文件如下（restoreconfig/single_40306.yaml）。

net: 
  bindIp: 127.0.0.1 
  port: 40306 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd11/mongod.pid} 
storage: 
  dbPath: /compile/cluster-restore/shd11/data/db/ 
  directoryPerDB: true 
  engine: wiredTiger 
  wiredTiger: 
    collectionConfig: {blockCompressor: snappy} 
    engineConfig: {directoryForIndexes: true, journalCompressor: snappy} 
    indexConfig: {prefixCompression: true} 
systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/shd11/log/mongod.log}

準備數據，將解壓后的shardsvr1文件拷貝到單節點dbPath目錄下。

cp -aR

/compile/download/backups/cac1efc8e65e42ecad8953352321bfeein02_6cfa6167d4114d7c8cec5b47f9a78dc5no02/* /compile/cluster-restore/shd11/data/db/

啟動進程。

./mongod -f restoreconfig/single_40306.yaml

步驟 2 連接單(dan)節(jie)點，執行(xing)配置命令。

連接命令：./mongo --host 127.0.0.1 --port 40306

執行如下命令，修改副本集配置信息。

var cf=db.getSiblingDB('local').system.replset.findOne();

cf['members'][0]['host']='127.0.0.1:40306';

cf['members'][1]['host']='127.0.0.1:40307';

cf['members'][2]['host']='127.0.0.1:40308';

cf['members'][0]['hidden']=false;

cf['members'][1]['hidden']=false;

cf['members'][2]['hidden']=false;

cf['members'][0]['priority']=1;

cf['members'][1]['priority']=1;

cf['members'][2]['priority']=1;

db.getSiblingDB('local').system.replset.remove({});

db.getSiblingDB('local').system.replset.insert(cf)

執行如下命令，清理內置賬號。

db.getSiblingDB('admin').dropAllUsers();

db.getSiblingDB('admin').dropAllRoles();

執行如下命令，更新configsvr信息。

連(lian)接命(ming)令(ling)：./mongo --host 127.0.0.1 --port 40306

var vs = db.getSiblingDB('admin').system.version.find();

while (vs.hasNext()) {

var curr = vs.next();

if (curr.hasOwnProperty('configsvrConnectionString')) {

db.getSiblingDB('admin').system.version.update({'_id' : curr._id}, {$set: {'configsvrConnectionString': 'config/127.0.0.1:40303,127.0.0.1:40304,127.0.0.1:40305'}});

}

}

執行如下命令，關閉單節點進程。

db.getSiblingDB('admin').shutdownServer();

步驟 3 搭建shardsvr1副本集(ji)。

準備副本集配置文件和目錄，將shardsvr1節點的dbPath文件拷貝到其他兩個節點目錄下。

cp -aR /compile/cluster-restore/shd11/data/db/ /compile/cluster-restore/shd12/data/db/

cp -aR /compile/cluster-restore/shd11/data/db/ /compile/cluster-restore/shd13/data/db/

修改shardsvr1-1節點配置文件，增加副本集配置屬性（restoreconfig/shardsvr_40306.yaml）。

--- replication.replSetName 的值，參考該章節中的shard的_id信息。

net: 
  bindIp: 127.0.0.1 
  port: 40306 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd11/mongod.pid} 
replication: {replSetName: shard_1} 
sharding: {archiveMovedChunks: false, clusterRole: shardsvr} 
storage: 
  dbPath: /compile/cluster-restore/shd11/data/db/ 
  directoryPerDB: true 
  engine: wiredTiger 
  wiredTiger: 
    collectionConfig: {blockCompressor: snappy} 
    engineConfig: {directoryForIndexes: true, journalCompressor: snappy} 
    indexConfig: {prefixCompression: true} 
systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/shd11/log/mongod.log}

啟動進程。

./mongod -f restoreconfig/shardsvr_40306.yaml

修改shardsvr1-2節點配置文件，增加副本集配置屬性（restoreconfig/shardsvr_40307.yaml）。

--replication.replSetName 的值，參考該章節中(zhong)的shard的_id信息。

net: 
  bindIp: 127.0.0.1 
  port: 40307 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd12/mongod.pid} 
replication: {replSetName: shard_1} 
sharding: {archiveMovedChunks: false, clusterRole: shardsvr} 
storage: 
  dbPath: /compile/cluster-restore/shd12/data/db/ 
  directoryPerDB: true 
  engine: wiredTiger 
  wiredTiger: 
    collectionConfig: {blockCompressor: snappy} 
    engineConfig: {directoryForIndexes: true, journalCompressor: snappy} 
    indexConfig: {prefixCompression: true} 
systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/shd12/log/mongod.log}

啟動進程。

./mongod -f restoreconfig/shardsvr_40307.yaml

修改shardsvr1-3節點配置文件，增加副本集配置屬性（restoreconfig/shardsvr_40308.yaml）。

--replication.replSetName 的(de)值，參考該章節中的(de)shard的(de)_id信息(xi)。

net: 
  bindIp: 127.0.0.1 
  port: 40308 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd13/mongod.pid} 
replication: {replSetName: shard_1} 
sharding: {archiveMovedChunks: false, clusterRole: shardsvr} 
storage: 
  dbPath: /compile/cluster-restore/shd13/data/db/ 
  directoryPerDB: true 
  engine: wiredTiger 
  wiredTiger: 
    collectionConfig: {blockCompressor: snappy} 
    engineConfig: {directoryForIndexes: true, journalCompressor: snappy} 
    indexConfig: {prefixCompression: true} 
systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/shd13/log/mongod.log}

啟動進程。

./mongod -f restoreconfig/shardsvr_40308.yaml

步驟 4 等待選主成功。

./mongo --host 127.0.0.1 --port 40306

執行(xing)命令rs.status()，查看是否(fou)已存在主節點Primary。
