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/sh0/mongodb.conf  root     41509  0.3  0.0 518016 54760 ?        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 ?        Sl   10:25   0:03 /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf1/config.conf  root     42170  0.9  0.0 467824 52392 ?        Sl   10:37   0:00 /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf2/config.conf

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 ?        Sl   10:25   0:03 /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf1/config.conf  root     42170  0.6  0.0 546720 41960 ?        Sl   10:37   0:00 /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf2/config.conf  root     42233  0.5  0.0 233536 10188 ?        Sl   10:38   0:00 /opt/mongodb/bin/mongos --config /data/mongodb/conf/ms0/mongos.conf  root     42286  0.4  0.0 241728  9056 ?        Sl   10:38   0:00 /opt/mongodb/bin/mongos --config /data/mongodb/conf/ms1/mongos.conf

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,          "$gleStats" : {                  "lastOpTime" : Timestamp(1444358911, 1),                  "electionId" : ObjectId("56172a4bc03d9b1667f8e928")          }  }  mongos> sh.enableSharding("mydb");  { "ok" : 1 }  mongos> sh.shardCollection("mydb.test", {"_id":1});  { "collectionsharded" : "mydb.test", "ok" : 1 }  mongos> sh.status();  --- Sharding Status ---    sharding version: {          "_id" : 1,          "minCompatibleVersion" : 5,          "currentVersion" : 6,          "clusterId" : ObjectId("561728b4030ea038bcb57fa0")  }    shards:          {  "_id" : "sh0",  "host" : "sh0/172.30.2.201:27010" }          {  "_id" : "sh1",  "host" : "sh1/172.30.2.201:27011" }    balancer:          Currently enabled:  yes          Currently running:  no          Failed balancer rounds in last 5 attempts:  0          Migration Results for the last 24 hours:                  No recent migrations    databases:          {  "_id" : "admin",  "partitioned" : false,  "primary" : "config" }          {  "_id" : "mydb",  "partitioned" : true,  "primary" : "sh0" }                  mydb.test                          shard key: { "_id" : 1 }                          chunks:                                  sh0     1                          { "_id" : { "$minKey" : 1 } } -->> { "_id" : { "$maxKey" : 1 } } on : sh0 Timestamp(1, 0)

可见分片已经配置完成了

七、添加开机启动项

$ sudo vim /etc/rc.local  /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh0/mongodb.conf  /opt/mongodb/bin/mongod --config /data/mongodb/conf/sh1/mongodb.conf  /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf0/config.conf  /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf1/config.conf  /opt/mongodb/bin/mongod --config /data/mongodb/conf/cf2/config.conf  /opt/mongodb/bin/mongos --config /data/mongodb/conf/ms0/mongos.conf  /opt/mongodb/bin/mongos --config /data/mongodb/conf/ms1/mongos.conf
