tcp 0 0 0.0.0.0:28000 0.0.0.0:* LISTEN 4086/mongod
五、在三个节点上启动用路由服务器
节点1
[root@orcl ~]# mongos -f /etc/route.conf
about to fork child process, waiting until server is ready for connections.
forked process: 3575
child process started successfully, parent exiting
[root@orcl ~]# netstat -anltp|grep 2701
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 3575/mongos
节点2
[root@localhost ~]# mongos -f /etc/route.conf
about to fork child process, waiting until server is ready for connections.
forked process: 3057
child process started successfully, parent exiting
[root@localhost ~]# netstat -anltp|grep 2701
tcp 0 0 0.0.0.0:27017
节点3
[root@db10g ~]# mongos -f /etc/route.conf
about to fork child process, waiting until server is ready for connections.
forked process: 4108
child process started successfully, parent exiting
[root@db10g ~]# netstat -anltp|grep 27017
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 4108/mongos
六、在三个节点启用shard
mongod -f /etc/sd1.conf
mongod -f /etc/sd2.conf
mongod -f /etc/sd3.conf
节点1
[root@orcl ~]# ps -ef |grep mongo
root 3472 1 2 19:15 ? 00:02:18 mongod -f /etc/config.conf
root 3575 1 0 19:28 ? 00:00:48 mongos -f /etc/route.conf
root 4135 1 0 20:52 ? 00:00:07 mongod -f /etc/sd1.conf
root 4205 1 0 20:55 ? 00:00:05 mongod -f /etc/sd2.conf
root 4265 1 0 20:58 ? 00:00:04 mongod -f /etc/sd3.conf
节点2
[root@localhost ~]# ps -ef |grep mongo
root 2998 1 1 19:15 ? 00:02:02 mongod -f /etc/config.conf
root 3057 1 1 19:28 ? 00:01:02 mongos -f /etc/route.conf
root 3277 1 1 20:52 ? 00:00:20 mongod -f /etc/sd1.conf
root 3334 1 6 20:56 ? 00:00:52 mongod -f /etc/sd2.conf
root 3470 1 1 21:01 ? 00:00:07 mongod -f /etc/sd3.conf
节点3
[root@db10g data]# ps -ef |grep mongo
root 4086 1 1 19:25 ? 00:01:58 mongod -f /etc/config.conf
root 4108 1 0 19:27 ? 00:00:55 mongos -f /etc/route.conf
root 4592 1 0 20:54 ? 00:00:07 mongod -f /etc/sd1.conf
root 4646 1 3 20:56 ? 00:00:30 mongod -f /etc/sd2.conf
root 4763 1 4 21:04 ? 00:00:12 mongod -f /etc/sd3.conf
七、配置副本集
192.168.1.30
[root@orcl ~]# mongo --port 27018
MongoDB shell version: 2.6.4
connecting to: 127.0.0.1:27018/test
> use admin
switched to db admin
> rs1={_id:"set1",members:[{_id:0,host:"192.168.1.30:27018",priority:2},{_id:1,host:"192.168.1.52:27018"},{_id:2,host:"192.168.1.108:27018",arbiterOnly:true}]}
{
"_id" : "set1",
"members" : [
{
"_id" : 0,
"host" : "192.168.1.30:27018",
"priority" : 2
},
{
"_id" : 1,
"host" : "192.168.1.52:27018"
},
{
"_id" : 2,
"host" : "192.168.1.108:27018",
"arbiterOnly" : true
}
]
}
> rs.initiate(rs1)
{
"info" : "Config now saved locally. Should come online in about a minute.",
"ok" : 1
}
192.168.1.52
[root@orcl ~]# mongo --port 27019
MongoDB shell version: 2.6.4
connecting to: 127.0.0.1:27019/test
> use admin
switched to db admin
> rs2={_id:"set2",members:[{_id:0,host:"192.168.1.52:27019",priority:2},{_id:1,host:"192.168.1.108:27019"},{_id:2,host:"192.168.1.30:27019",arbiterOnly:true}]}
{
"_id" : "set2",
"members" : [
{
"_id" : 0,
"host" : "192.168.1.52:27019",
"priority" : 2
},
{
"_id" : 1,
"host" : "192.168.1.108:27019"
},
{
"_id" : 2,
"host" : "192.168.1.30:27019",
"arbiterOnly" : true
}
]
}
> rs.initiate(rs2);
{
"info" : "Config now saved locally. Should come online in about a minute.",
"ok" : 1
}
192.168.1.108
[root@localhost sd3]# mongo --port 27020
MongoDB shell version: 2.6.4
connecting to: 127.0.0.1:27020/test
> use admin
switched to db admin
> rs3={_id:"set3",members:[{_id:0,host:"192.168.1.108:27020",priority:2},{_id:1,host:"192.168.1.30:27020"},{_id:2,host:"192.168.1.52:27020",arbiterOnly:true}]}
{
"_id" : "set3",
"members" : [
{
"_id" : 0,
"host" : "192.168.1.108:27020",
"priority" : 2
},
{
"_id" : 1,
"host" : "192.168.1.30:27020"
},
{
"_id" : 2,
"host" : "192.168.1.52:27020",
"arbiterOnly" : true
}
]
}
> rs.initiate(rs3);
{
"info" : "Config now saved locally. Should come online in about a minute.",
"ok" : 1
}
八、添加分片
在三个节点上任一个节点都可以操作
192.168.1.30
[root@orcl sd3]# mongo --port 27017
MongoDB shell version: 2.6.4
connecting to: 127.0.0.1:27017/test
mongos> use admin
switched to db admin
mongos> db.runCommand({addshard:"set1/192.168.1.30:27018,192.168.1.52:27018,192.168.1.108:27018"})
{ "shardAdded" : "set1", "ok" : 1 }
mongos> db.runCommand({addshard:"set2/192.168.1.30:27019,192.168.1.52:27019,192.168.1.108:27019"})
{ "shardAdded" : "set2", "ok" : 1 }
mongos> db.runCommand({addshard:"set3/192.168.1.30:27020,192.168.1.52:27020,192.168.1.108:27020"})
{ "shardAdded" : "set3", "ok" : 1 }
九、查看分片信息
mongos> db.runCommand({listshards : 1})
{
"shards" : [
{
"_id" : "set1",
"host" : "set1/192.168.1.30:27018,192.168.1.52:27018"
},
{
"_id" : "set2",
"host" : "set2/192.168.1.108:27019,192.168.1.52:27019"
},
{
"_id" : "set3",
"host" : "set3/192.168.1.108:27020,192.168.1.30:27020"
}
],
"ok" : 1
}
十、删除分片
mongos> db.runCommand({removeshard:"set3"})
{
"msg" : "draining started successfully",
"state" : "started",
"shard" : "set3",
"ok" : 1
}
十一、管理分片
mongos> use config
switched to db config
mongos> db.shards.find();
{ "_id" : "set1", "host" : "set1/192.168.1.30:27018,192.168.1.52:27018" }
{ "_id" : "set2", "host" : "set2/192.168.1.108:27019,192.168.1.52:27019" }
{ "_id" : "set3", "host" : "set3/192.168.1.108:27020,192.168.1.30:27020" }
十二、对要分片的库和表声明
切换到admin库
mongos> use admin
声明test库允许分片
mongos> db.runCommand({enablesharding:"test"})
{ "ok" : 1 }
声明users表要分片
mongos> db.runCommand({shardcollection:"test.lineqi",key:{id:"hashed"}})
{ "collectionsharded" : "test.lineqi", "ok" : 1 }
十三、测试脚本
切换到test
mongos>use test
mongos> for (var i = 1; i <= 100000; i++) db.lineqi.save({id:i,name:"12345678",sex:"male",age:27,value:"test"});
WriteResult({ "nInserted" : 1 })
十四、测试结果
查看分片信息
mongos> use config
switched to db config
mongos> db.chunks.find();
