操作步驟

步(bu)驟 1 準備單節(jie)點(dian)(dian)配置文件和目(mu)錄，以單節(jie)點(dian)(dian)方(fang)式啟動進程。

配置文件如下（restoreconfig/single_40309.yaml）。

net: 
  bindIp: 127.0.0.1 
  port: 40309 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd21/mongod.pid} 
storage: 
  dbPath: /compile/cluster-restore/shd21/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/shd21/log/mongod.log}

準備數據，將解壓后的shardsvr2文件拷貝到單節點dbPath目錄下。

cp -aR

/compile/download/backups/cac1efc8e65e42ecad8953352321bfeein02_92b196d2401041a7af869a2a3cab7079no02/* /compile/cluster-restore/shd21/data/db/

啟動進程。

./mongod -f restoreconfig/single_40309.yaml

步驟(zou) 2 連接單節點，執行配置(zhi)命令。

連接命令：./mongo --host 127.0.0.1 --port 40309

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']='127.0.0.1:40309';

cf['members'][1]['host']='127.0.0.1:40310';

cf['members'][2]['host']='127.0.0.1:40311';

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。

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(zou) 3 搭建shardsvr2副本(ben)集。

準備副本集配置文件和目錄，將shardsvr2節點的dbPath文件拷貝到其他兩個節點目錄下。

cp -aR /compile/cluster-restore/shd21/data/db/ /compile/cluster-restore/shd22/data/db/

cp -aR /compile/cluster-restore/shd21/data/db/ /compile/cluster-restore/shd23/data/db/

修改shardsvr2-1節點配置文件，增加副本集配置屬性（restoreconfig/shardsvr_40309.yaml）。

--replication.replSetName 的(de)值(zhi)，參考該(gai)章節中的(de)shard的(de)_id信(xin)息(xi)。

net: 
  bindIp: 127.0.0.1 
  port: 40309 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd21/mongod.pid} 
replication: {replSetName: shard_2} 
sharding: {archiveMovedChunks: false, clusterRole: shardsvr} 
storage: 
  dbPath: /compile/cluster-restore/shd21/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/shd21/log/mongod.log}

啟動進程。

./mongod -f restoreconfig/shardsvr_40309.yaml

修改shardsvr2-2節點配置文件，增加副本集配置屬性（restoreconfig/shardsvr_40310.yaml）。

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

net: 
  bindIp: 127.0.0.1 
  port: 40310 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd22/mongod.pid} 
replication: {replSetName: shard_2} 
sharding: {archiveMovedChunks: false, clusterRole: shardsvr} 
storage: 
  dbPath: /compile/cluster-restore/shd22/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/shd22/log/mongod.log}

啟動進程。

./mongod -f restoreconfig/shardsvr_40310.yaml

修改shardsvr2-3節點(dian)配(pei)置文件，增(zeng)加副本集配(pei)置屬(shu)性（restoreconfig/shardsvr_40311.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: 40311 
  unixDomainSocket: {enabled: false} 
processManagement: {fork: true, pidFilePath: /compile/cluster-restore/shd23/mongod.pid} 
replication: {replSetName: shard_2} 
sharding: {archiveMovedChunks: false, clusterRole: shardsvr} 
storage: 
  dbPath: /compile/cluster-restore/shd23/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/shd23/log/mongod.log}

啟動進程。

./mongod -f restoreconfig/shardsvr_40311.yaml

步驟 4 等待(dai)選主成功。

./mongo --host 127.0.0.1 --port 40309

執行命(ming)令rs.status()，查看(kan)是否已存(cun)在主(zhu)節點Primary。
