分片1步骤

--172.16.0.124分片1

创建目录

mkdir -p /home/data/shard1_1

mkdir -p /home/Apps

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

 

启动服务

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard1 --port 11731 --dbpath /home/data/shard1_1 --logpath /home/data/shard1_1/shard1_1.log --logappend  --oplogSize 5000 --fork

 

--172.16.0.127分片1

mkdir -p /home/data/shard1_2

mkdir -p /home/Apps

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

启动服务

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard1 --port 11731 --dbpath /home/data/shard1_2 --logpath /home/data/shard1_2/shard1_2.log --logappend  --oplogSize 5000 --fork

--172.16.0.115分片1仲载

mkdir -p /home/data/shard1_3

mkdir -p /home/Apps

mkdir -p /home/data/config

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

 

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard1 --port 11731 --dbpath /home/data/shard1_3 --logpath /home/data/shard1_3/shard1_3.log --logappend  --oplogSize 5000 --fork

 

分片1启动好,初始化Replica Set1  arbiterOnly:true仲裁

在分片1 172.16.0.124操作如下

 

/home/Apps/mongo/bin/mongo --port 11731

 

config={_id:'shard1',members:[{_id:0,host:'172.16.0.124:11731'},{_id:1,host:'172.16.0.127:11731'},{_id:2,host:'172.16.0.115:11731',arbiterOnly:true}]}

 

rs.initiate(config)

分片2步骤

--172.16.0.122分片2

创建目录

mkdir -p /home/data/shard2_1

mkdir -p /home/Apps

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

 

启动服务

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard2 --port 11732 --dbpath /home/data/shard2_1 --logpath /home/data/shard2_1/shard2_1.log --oplogSize 50000 --logappend --fork

 

--172.16.0.125分片2

mkdir -p /home/data/shard2_2

mkdir -p /home/Apps

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

启动服务

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard2 --port 11732 --dbpath /home/data/shard2_2 --logpath /home/data/shard2_2/shard2_2.log   --oplogSize 50000 --logappend --fork

--172.16.0.103分片2仲载

mkdir -p /home/data/shard2_3

mkdir -p /home/Apps

mkdir -p /home/data/config

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

 

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard2 --port 11732 --dbpath /home/data/shard2_3 --logpath /home/data/shard2_3/shard2_3.log --oplogSize 50000 --logappend --fork

 

 

分片2启动好,初始化Replica Set 2  arbiterOnly:true仲裁

在分片2 172.16.0.122操作如下

/home/Apps/mongo/bin/mongo --port 11732

 

config={_id:'shard2',members:[{_id:0,host:'172.16.0.122:11732'},{_id:1,host:'172.16.0.125:11732'},{_id:2,host:'172.16.0.103:11732',arbiterOnly:true}]}

 

rs.initiate(config)

分片3步骤

--172.16.0.121分片3

创建目录

mkdir -p /home/data/shard3_1

mkdir -p /home/Apps

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

 

启动服务

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard3 --port 11733 --dbpath /home/data/shard3_1 --logpath /home/data/shard3_1/shard3_1.log --oplogSize 50000 --logappend --fork

 

--172.16.0.123分片3

mkdir -p /home/data/shard2_2

mkdir -p /home/Apps

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

启动服务

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard3 --port 11733 --dbpath /home/data/shard3_2 --logpath /home/data/shard3_2/shard3_2.log --oplogSize 50000 --logappend --fork

--172.16.0.114分片3仲载

mkdir -p /home/data/shard3_3

mkdir -p /home/Apps

mkdir -p /home/data/config

 

tar zxvf mongodb-linux-x86_64-2.4.7.tgz

mv mongodb-linux-x86_64-2.4.7 /home/Apps/mongo

 

/home/Apps/mongo/bin/mongod --shardsvr --replSet shard3 --port 11733 --dbpath /home/data/shard3_3 --logpath /home/data/shard3_3/shard3_3.log --oplogSize 50000 --logappend --fork

 

 

分片3启动好,初始化Replica Set 3  arbiterOnly:true仲裁

在分片3 172.16.0.121操作如下

/home/Apps/mongo/bin/mongo --port 11733

 

config={_id:'shard3',members:[{_id:0,host:'172.16.0.121:11733'},{_id:1,host:'172.16.0.123:11733'},{_id:2,host:'172.16.0.114:11733',arbiterOnly:true}]}

 

rs.initiate(config)

 

配置3个分片Config Server

172.16.0.115,172.16.0.103,172.16.0.114 这三台执行操作,如下面代码

/home/Apps/mongo/bin/mongod --configsvr --dbpath /home/data/config --port 30000 --logpath /home/data/config/config.log --logappend --fork

 

 

配置3个分片Route Process

172.16.0.115,172.16.0.103,172.16.0.114 这三台执行操作,如下面代码

/home/Apps/mongo/bin/mongos --configdb 172.16.0.115:30000,172.16.0.103:30000,172.16.0.114:30000 -port 60000 --chunkSize 1 --logpath /home/data/mongos.log --logappend --fork

 

 

配置Shard Cluster

172.16.0.115,172.16.0.103,172.16.0.114 这三台其中一台执行操作,如下面代码

 

/home/Apps/mongo/bin/mongo --port 60000

 

use admin

db.runCommand({addshard:"shard1/172.16.0.124:11731, 172.16.0.127:11731, 172.16.0.115:11731"})

 

db.runCommand({addshard:"shard2/172.16.0.122:11732, 172.16.0.125:11732, 172.16.0.103:11732"})

 

db.runCommand({addshard:"shard3/172.16.0.121:11733, 172.16.0.123:11733, 172.16.0.114:11733"})

 

 

 

接下来激活分片,如下面的代码所示:    采用hash分片

db.runCommand({enablesharding:"test"})

db.runCommand({shardcollection:"test.users",key:{id:"hashed"}})

 

 

 

强调服务时间必须要同步,否则有问题
