恢复shardsvr1副本集

准备目录

rm -rf /compile/cluster-restore/shd1*

mkdir -p /compile/cluster-restore/shd11/data/db

mkdir -p /compile/cluster-restore/shd11/log

mkdir -p /compile/cluster-restore/shd12/data/db

mkdir -p /compile/cluster-restore/shd12/log

mkdir -p /compile/cluster-restore/shd13/data/db

mkdir -p /compile/cluster-restore/shd13/log

操作步骤

准备单节点配置文件和目录，以单节点方式启动进程。

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}

准备数据，将解压后的shardsvr1文件拷贝到单节点dbPath目录下。
cp -aR

/compile/download/backups/cac1efc8e65e42ecad8953352321bfeein02_6cfa6167d4114d7c8cec5b47f9a78dc5no02/* /compile/cluster-restore/shd11/data/db/
启动进程。
./mongod -f restoreconfig/single_40306.yaml

连接单节点，执行配置命令。

连接命令：./mongo --host 127.0.0.1 --port 40306
1. 执行如下命令，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)
2. 执行如下命令，清理内置账号。
  db.getSiblingDB('admin').dropAllUsers();
  
  db.getSiblingDB('admin').dropAllRoles();
3. 执行如下命令，更新configsvr信息。
  连接命令：./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'}});
  
  }
  
  }
4. 执行如下命令，关闭单节点进程。
  db.getSiblingDB('admin').shutdownServer();

搭建shardsvr1副本集。

准备副本集配置文件和目录，将shardsvr1节点的dbPath文件拷贝到其他两个节点目录下。
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节点配置文件，增加副本集配置属性（restoreconfig/shardsvr_40306.yaml）。

--- replication.replSetName 的值，参考该章节中的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}

启动进程。
./mongod -f restoreconfig/shardsvr_40306.yaml

修改shardsvr1-2节点配置文件，增加副本集配置属性（restoreconfig/shardsvr_40307.yaml）。

--- replication.replSetName 的值，参考该章节中的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}

启动进程。
./mongod -f restoreconfig/shardsvr_40307.yaml

修改shardsvr1-3节点配置文件，增加副本集配置属性（restoreconfig/shardsvr_40308.yaml）。

--- replication.replSetName 的值，参考该章节中的shard的_id信息。

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}
