一、环境
$ cat /etc/redhat-release CentOS Linux release 7.0.1406 (Core) $ uname -a Linux zhaopin-2-201 3.10.0-123.el7.x86_64 #1 SMP Mon Jun 30 12:09:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux $ mongo --version MongoDB shell version: 3.0.6
二、配置Shard Server
1.创建目录
$ sudo mkdir -p /data/mongodb/{data/{sh0,sh1},backup/{sh0,sh1},log/{sh0,sh1},conf/{sh0,sh1}}
2.准备配置文件
第一个分片：
$ sudo vim /data/mongodb/conf/sh0/mongodb.conf # base port = 27010 maxConns = 800 filePermissions = 0700 fork = true noauth = true directoryperdb = true dbpath = /data/mongodb/data/sh0 pidfilepath = /data/mongodb/data/sh0/mongodb.pid oplogSize = 10 journal = true # security nohttpinterface = true rest = false # log logpath = /data/mongodb/log/sh0/mongodb.log logRotate = rename logappend = true slowms = 50 replSet = sh0 shardsvr = true
第二个分片：
$ sudo vim /data/mongodb/conf/sh1/mongodb.conf # base port = 27011 maxConns = 800 filePermissions = 0700 fork = true noauth = true directoryperdb = true dbpath = /data/mongodb/data/sh1 pidfilepath = /data/mongodb/data/sh1/mongodb.pid oplogSize = 10 journal = true # security nohttpinterface = true rest = false # log logpath = /data/mongodb/log/sh1/mongodb.log logRotate = rename logappend = true slowms = 50 replSet = sh1 shardsvr = true
3.启动Shard Server
$ sudo /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh0/mongodb.conf about to fork child process, waiting until server is ready for connections. forked process: 41492 child process started successfully, parent exiting $ sudo /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh1/mongodb.conf about to fork child process, waiting until server is ready for connections. forked process: 41509 child process started successfully, parent exiting $ ps aux | grep mongo | grep -v grep root 41492 0.5 0.0 518016 54604 ? Sl 10:09 0:00 /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh0/mongodb.conf root 41509 0.5 0.0 516988 51824 ? Sl 10:09 0:00 /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh1/mongodb.conf $ mongo --port 27010 MongoDB shell version: 3.0.6 connecting to: 127.0.0.1:27010/test > bye $ mongo --port 27011 MongoDB shell version: 3.0.6 connecting to: 127.0.0.1:27011/test > bye
三、配置Config Server
1.创建目录
$ sudo mkdir -p /data/mongodb/{data/{cf0,cf1,cf2},backup/{cf0,cf1,cf2},log/{cf0,cf1,cf2},conf/{cf0,cf1,cf2}}
2.准备配置文件
第一个配置服务器：
$ sudo vim /data/mongodb/conf/cf0/config.conf # base port = 27000 maxConns = 800 filePermissions = 0700 fork = true noauth = true directoryperdb = true dbpath = /data/mongodb/data/cf0 pidfilepath = /data/mongodb/data/cf0/config.pid oplogSize = 10 journal = true # security nohttpinterface = true rest = false # log logpath = /data/mongodb/log/cf0/config.log logRotate = rename logappend = true slowms = 50 configsvr = true
第二个配置服务器：
$ sudo vim /data/mongodb/conf/cf1/config.conf # base port = 27001 maxConns = 800 filePermissions = 0700 fork = true noauth = true directoryperdb = true dbpath = /data/mongodb/data/cf1 pidfilepath = /data/mongodb/data/cf1/config.pid oplogSize = 10 journal = true # security nohttpinterface = true rest = false # log logpath = /data/mongodb/log/cf1/config.log logRotate = rename logappend = true slowms = 50 configsvr = true
第三个配置服务器：
$ sudo vim /data/mongodb/conf/cf2/config.conf # base port = 27002 maxConns = 800 filePermissions = 0700 fork = true noauth = true directoryperdb = true dbpath = /data/mongodb/data/cf2 pidfilepath = /data/mongodb/data/cf2/config.pid oplogSize = 10 journal = true # security nohttpinterface = true rest = false # log logpath = /data/mongodb/log/cf2/config.log logRotate = rename logappend = true slowms = 50 configsvr = true
3.启动
$ sudo /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf0/config.conf about to fork child process, waiting until server is ready for connections. forked process: 41759 child process started successfully, parent exiting $ sudo /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf1/config.conf about to fork child process, waiting until server is ready for connections. forked process: 41774 child process started successfully, parent exiting $ sudo /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf2/config.conf about to fork child process, waiting until server is ready for connections. forked process: 42170 child process started successfully, parent exiting $ ps aux | grep mongo | grep -v grep root 41492 0.3 0.0 518016 54728 ?

Sl 10:09 0:06 /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh1/mongodb.conf root 41855 0.4 0.0 467828 51684 ? Sl 10:25 0:03 /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf0/config.conf root 41870 0.4 0.0 467828 52312 ?

四、配置Query Routers
1.创建目录
$ sudo mkdir -p /data/mongodb/{data/{ms0,ms1},backup/{ms0,ms1},log/{ms0,ms1},conf/{ms0,ms1}}
2.准备配置文件
第一个配置服务器：
$ sudo vim /data/mongodb/conf/ms0/mongos.conf # base port = 30000 maxConns = 800 filePermissions = 0700 fork = true pidfilepath = /data/mongodb/data/ms0/mongos.pid # log logpath = /data/mongodb/log/ms0/mongos.log logRotate = rename logappend = true configdb = 172.30.2.201:27000,172.30.2.201:27001,172.30.2.201:27002
第二个配置服务器：
$ sudo vim /data/mongodb/conf/ms1/mongos.conf # base port = 30000 maxConns = 800 filePermissions = 0700 fork = true pidfilepath = /data/mongodb/data/ms1/mongos.pid # log logpath = /data/mongodb/log/ms1/mongos.log logRotate = rename logappend = true configdb = 172.30.2.201:27000,172.30.2.201:27001,172.30.2.201:27002
3.启动
$ sudo /opt/mongodb/bin/mongos --config /data/mongodb/conf/ms0/mongos.conf about to fork child process, waiting until server is ready for connections. forked process: 42233 child process started successfully, parent exiting $ sudo /opt/mongodb/bin/mongos --config /data/mongodb/conf/ms1/mongos.conf about to fork child process, waiting until server is ready for connections. forked process: 42286 child process started successfully, parent exiting $ ps aux | grep mongo | grep -v grep root 41492 0.3 0.0 518016 54728 ? Sl 10:09 0:06 /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh0/mongodb.conf root 41509 0.3 0.0 518016 54760 ? Sl 10:09 0:07 /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh1/mongodb.conf root 41855 0.4 0.0 546724 37812 ? Sl 10:25 0:03 /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf0/config.conf root 41870 0.4 0.0 546724 38188 ?

五、初始化单节点副本集
配置副本集的好处是为了高可用，配置单节点是我自己为了节省时间，后续添加节点和副本集的操作一样，分片的配置不需要修改
分片一：
$ mongo --port 27010
MongoDB shell version: 3.0.6
connecting to: 127.0.0.1:27010/test
> use admin
switched to db admin
> cfg={_id:"sh0", members:[ {_id:0,host:"172.30.2.201:27010"}] }
{
"_id" : "sh0",
"members" : [
{
"_id" : 0,
"host" : "172.30.2.201:27010"
}
]
}
> rs.initiate( cfg );
{ "ok" : 1 }
sh0:OTHER> rs.status();
{
"set" : "sh0",
"date" : ISODate("2015-10-09T02:45:39.178Z"),
"myState" : 1,
"members" : [
{
"_id" : 0,
"name" : "172.30.2.201:27010",
"health" : 1,
"state" : 1,
"stateStr" : "PRIMARY",
"uptime" : 2197,
"optime" : Timestamp(1444358731, 1),
"optimeDate" : ISODate("2015-10-09T02:45:31Z"),
"electionTime" : Timestamp(1444358731, 2),
"electionDate" : ISODate("2015-10-09T02:45:31Z"),
"configVersion" : 1,
"self" : true
}
],
"ok" : 1
}
sh0:PRIMARY>
bye
分片二：
$ mongo --port 27011
MongoDB shell version: 3.0.6
connecting to: 127.0.0.1:27011/test
> cfg={_id:"sh1", members:[ {_id:0,host:"172.30.2.201:27011"}] }
{
"_id" : "sh1",
"members" : [
{
"_id" : 0,
"host" : "172.30.2.201:27011"
}
]
}
> rs.initiate( cfg );
{ "ok" : 1 }
sh1:OTHER> rs.status();
{
"set" : "sh1",
"date" : ISODate("2015-10-09T02:46:32.961Z"),
"myState" : 1,
"members" : [
{
"_id" : 0,
"name" : "172.30.2.201:27011",
"health" : 1,
"state" : 1,
"stateStr" : "PRIMARY",
"uptime" : 2244,
"optime" : Timestamp(1444358790, 1),
"optimeDate" : ISODate("2015-10-09T02:46:30Z"),
"electionTime" : Timestamp(1444358790, 2),
"electionDate" : ISODate("2015-10-09T02:46:30Z"),
"configVersion" : 1,
"self" : true
}
],
"ok" : 1
}
sh1:PRIMARY>
bye
六、配置分片
$ mongo --port 30000
MongoDB shell version: 3.0.6
connecting to: 127.0.0.1:30000/test
mongos> use admin;
switched to db admin
mongos> sh.addShard("sh0/172.30.2.201:27010");
{ "shardAdded" : "sh0", "ok" : 1 }
mongos> sh.addShard("sh1/172.30.2.201:27011");
{ "shardAdded" : "sh1", "ok" : 1 }
mongos> use mydb;
switched to db mydb
mongos> db.createCollection("test");
{
"ok" : 1,
"$gleStats" : {
"lastOpTime" : Timestamp(1444358911, 1),
"electionId" : ObjectId("56172a4bc03d9b1667f8e928")
}
}
mongos> sh.enableSharding("mydb");
{ "ok" : 1 }
mongos> sh.shardCollection("mydb.test", {"_id":1});
{ "collectionsharded" : "mydb.test", "ok" : 1 }
mongos> sh.status();
