准备目录 rm -rf /compile/cluster-restore/cfg* mkdir -p /compile/cluster-restore/cfg1/data/db mkdir -p /compile/cluster-restore/cfg1/log mkdir -p /compile/cluster-restore/cfg2/data/db mkdir -p /compile/cluster-restore/cfg2/log mkdir -p /compile/cluster-restore/cfg3/data/db mkdir -p /compile/cluster-restore/cfg3/log

操作步骤 准备单节点配置文件和数据目录，以单节点方式启动进程。 配置文件如下（restoreconfig/single_40303.yaml）。 net: bindIp: 127.0.0.1 port: 40303 unixDomainSocket: {enabled: false} processManagement: {fork: true, pidFilePath: /compile/cluster-restore/cfg1/configsvr.pid} storage: dbPath: /compile/cluster-restore/cfg1/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/cfg1/log/configsingle.log} 准备数据，将解压后的configsvr文件拷贝到单节点dbPath目录下。 cp -aR /compile/download/backups/cac1efc8e65e42ecad8953352321bfeein02_41c8a32fb10245899708dea453a8c5c9no02/* /compile/cluster-restore/cfg1/data/db/ 启动进程。 ./mongod -f restoreconfig/single_40303.yaml 连接单节点，执行配置命令。 连接命令：./mongo --host 127.0.0.1 --port 40303 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']='127.0.0.1:40303'; cf['members'][1]['host']='127.0.0.1:40304'; cf['members'][2]['host']='127.0.0.1:40305'; 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) 执行如下命令，清理内置账号。 db.getSiblingDB('admin').dropAllUsers(); db.getSiblingDB('admin').dropAllRoles(); 执行如下命令，更新dds mongos和shard信息。 db.getSiblingDB('config').mongos.remove({}); 先查询config.shards表中的多个shard的_id信息，用于下面语句的_id的查询条件。逐个更新每条记录。 db.getSiblingDB('config').shards.update({'_id' : 'shard_1'},{$set: {'host': 'shard_1/127.0.0.1:40306,127.0.0.1:40307,127.0.0.1:40308'}}) db.getSiblingDB('config').shards.update({'_id' : 'shard_2'},{$set: {'host': 'shard_2/127.0.0.1:40309,127.0.0.1:40310,127.0.0.1:40311'}}) db.getSiblingDB('config').mongos.find({}); db.getSiblingDB('config').shards.find({}); 执行如下命令，关闭单节点进程。 db.getSiblingDB('admin').shutdownServer(); 搭建configsvr副本集。 准备副本集配置文件和目录，将configsvr1节点的dbPath文件拷贝到其他两个节点目录下。 cp -aR /compile/cluster-restore/cfg1/data/db/ /compile/cluster-restore/cfg2/data/db/ cp -aR /compile/cluster-restore/cfg1/data/db/ /compile/cluster-restore/cfg3/data/db/ 修改configsvr-1节点配置文件，增加副本集配置属性（restoreconfig/configsvr_40303.yaml）。 net: bindIp: 127.0.0.1 port: 40303 unixDomainSocket: {enabled: false} processManagement: {fork: true, pidFilePath: /compile/cluster-restore/cfg1/configsvr.pid} replication: {replSetName: config} sharding: {archiveMovedChunks: false, clusterRole: configsvr} storage: dbPath: /compile/cluster-restore/cfg1/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/cfg1/log/configsvr.log} 启动进程。 ./mongod -f restoreconfig/configsvr_40303.yaml 修改configsvr-2节点配置文件，增加副本集配置属性（restoreconfig/configsvr_40304.yaml）。 net: bindIp: 127.0.0.1 port: 40304 unixDomainSocket: {enabled: false} processManagement: {fork: true, pidFilePath: /compile/cluster-restore/cfg2/configsvr.pid} replication: {replSetName: config} sharding: {archiveMovedChunks: false, clusterRole: configsvr} storage: dbPath: /compile/cluster-restore/cfg2/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/cfg2/log/configsvr.log} 启动进程 ./mongod -f restoreconfig/configsvr_40304.yaml 修改configsvr-3节点配置文件，增加副本集配置属性（restoreconfig/configsvr_40305.yaml）。 net: bindIp: 127.0.0.1 port: 40305 unixDomainSocket: {enabled: false} processManagement: {fork: true, pidFilePath: /compile/cluster-restore/cfg3/configsvr.pid} replication: {replSetName: config} sharding: {archiveMovedChunks: false, clusterRole: configsvr} storage: dbPath: /compile/cluster-restore/cfg3/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/cfg3/log/configsvr.log} 启动进程。 ./mongod -f restoreconfig/configsvr_40305.yaml 等待选主成功。 ./mongo --host 127.0.0.1 --port 40303 执行命令rs.status()，查看是否已存在主节点Primary。
