分片和副本集混合運用：

基本架構圖：

搭建詳細配置：

3個shard + 3個replicat set + 3個configserver + 3個Mongos

在三臺Linux機器的mongo根目錄下建立如下文件夾：

Log:

/usr/local/mongodb/logs/a1

/usr/local/mongodb/logs/b1

/usr/local/mongodb/logs/c1

/usr/local/mongodb/logs/configserver1

DB:

/usr/local/mongodb/db/a1

/usr/local/mongodb/db/b1

/usr/local/mongodb/db/c1

/usr/local/mongodb/db/configserver1

bigdata-sh-a1.conf:

# mongod config

systemLog:
  destination: file
  logAppend: true
  path: /usr/local/mongodb/logs/a1/mongodb.log


# Where and how to store data.
storage:
  dbPath: /usr/local/mongodb/db/a1
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# how the process runs
# fork : fork and run in background
# pidFilePath:location of pidfile 
processManagement:
  fork: true
  pidFilePath: /usr/local/mongodb/pidFile/mongod-a1.pid

# network interfaces
# Listen to local interface only, comment to listen on all interfaces.
net:
  port: 28111
  bindIp: 0.0.0.0

#security:  enabled  disabled
#security:
#  keyFile: /mongodb/keyfile
#  clusterAuthMode: keyFile

#operationProfiling:
operationProfiling:
   slowOpThresholdMs: 1000
   mode: slowOp

#replication:

replication:
  replSetName: bigdata-sh-a

#sharding:

sharding:
  clusterRole: shardsvr

## Enterprise-Only Options

#auditLog:

#snmp:

bigdata-sh-configserver1.conf:

# mongod config

systemLog:
  destination: file
  logAppend: true
  path: /usr/local/mongodb/logs/configserver1/mongodb.log


# Where and how to store data.
storage:
  dbPath: /usr/local/mongodb/db/configserver1
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# how the process runs
# fork : fork and run in background
# pidFilePath:location of pidfile
processManagement:
  fork: true
  pidFilePath: /usr/local/mongodb/pidFile/mongod-configserver1.pid

# network interfaces
# Listen to local interface only, comment to listen on all interfaces.
net:
  port: 28200
  bindIp: 0.0.0.0


#security:  enabled  disabled

#  clusterAuthMode: keyFile

#sharding:

配置完成後，啟動服務：

./mongod -f ../conf/bigdata-sh-a1.conf

./mongod -f ../conf/bigdata-sh-b1.conf

./mongod -f ../conf/bigdata-sh-c1.conf

./mongod -f ../conf/bigdata-sh-configserver1.conf

./mongod -f ../conf/bigdata-sh-a2.conf

./mongod -f ../conf/bigdata-sh-b2.conf

./mongod -f ../conf/bigdata-sh-c2.conf

./mongod -f ../conf/bigdata-sh-configserver2.conf

./mongod -f ../conf/bigdata-sh-a3.conf

./mongod -f ../conf/bigdata-sh-b3.conf

./mongod -f ../conf/bigdata-sh-c3.conf

./mongod -f ../conf/bigdata-sh-configserver3.conf

創建副本集：

./mongo hadoop1:28111/admin

use admin

rs.initiate()

rs.add("hadoop2:28111")

rs.add("hadoop3:28111")

./mongo hadoop2:28112/admin

rs.initiate()

rs.add("hadoop1:28112")

rs.add("hadoop3:28112")

./mongo hadoop3:28113/admin

rs.initiate()

rs.add("hadoop2:28113")

rs.add("hadoop1:28113")

./mongo hadoop1:28200/admin

rs.initiate()

rs.add("hadoop2:28200")

rs.add("hadoop3:28200")

在三臺linux上啟動Mongos：

./mongos --port 28300 --configdb bigdata-cs/hadoop1:28200,hadoop2:28200,hadoop3:28200 --fork --logpath /usr/local/mongodb/logs/mongos/mongos.log --bind_ip 0.0.0.0

連接其中一臺Mongos，增加分片：

./mongo hadoop1:28300/admin

use admin

sh.addShard("bigdata-sh-a/hadoop1:28111,hadoop2:28111,hadoop3:28111")

sh.addShard("bigdata-sh-b/hadoop1:28112,hadoop2:28112,hadoop3:28112")

sh.addShard("bigdata-sh-c/hadoop1:28113,hadoop2:28113,hadoop3:28113")

sh.enableSharding("shop")

sh.shardCollection("shop.goods",{"goodid": 1});

插入大量數據進行驗證：

for(var i=80002; i<=90001; i++){ db.goods.insert({goodid: i, name: "My first shard"}) }

大功告成！
