p(1392313137, 1), "optimeDate" : ISODate("2014-02-13T17:38:57Z"), "self" : true }, { "_id" : 1, "name" : "172.17.253.217:27017", "health" : 1, "state" : 2, "stateStr" : "SECONDARY", "uptime" : 815, "optime" : Timestamp(1392313137, 1), "optimeDate" : ISODate("2014-02-13T17:38:57Z"), "lastHeartbeat" : ISODate("2014-02-13T10:53:10Z"), "lastHeartbeatRecv" : ISODate("2014-02-13T10:53:11Z"), "pingMs" : 1, "syncingTo" : "172.17.253.216:27017" }, { "_id" : 2, "name" : "172.17.253.67:27017", "health" : 1, "state" : 7, "stateStr" : "ARBITER", "uptime" : 776, "lastHeartbeat" : ISODate("2014-02-13T10:53:11Z"), "lastHeartbeatRecv" : ISODate("2014-02-13T10:53:10Z"), "pingMs" : 0 } ], "ok" : 1 }

同样方法，配置shard2用到的replica sets:

这里我们之添加172.17.253.217:27018单机

2.3配置三台config server,启动配置节点

Server1:
mkdir -p /mongodb/data/config
./mongod –configsvr –dbpath /mongodb/data/config –port 20000 –logpath /mongodb/data/config.log –logappend –fork #config server也需要dbpath

Server2:
mkdir -p /mongodb/data/config
./mongod –configsvr –dbpath /mongodb/data/config –port 20000 –logpath /mongodb/data/config.log –logappend –fork

Server3:
mkdir -p /mongodb/data/config
./mongod –configsvr –dbpath /mongodb/data/config –port 20000 –logpath /mongodb/data/config.log –logappend –fork

方式二：

由于配置文件比较多，建议写在文件中

Server1:

#config.conf

dbpath=/opt/mongodb/data/config
logpath = /opt/mongodb/data/config.log
logappend = true
bind_ip=172.17.253.216
port = 20000
fork = true

[root@localhost bin]# ./mongod -configsvr -f config.conf 
about to fork child process, waiting until server is ready for connections.
forked process: 24132
all output going to: /opt/mongodb/data/config.log
child process started successfully, parent exiting

Server2:

dbpath=/opt/mongodb/data/config
logpath = /opt/mongodb/data/config.log
logappend = true
bind_ip=172.17.253.217
port = 20000
fork = true

Server3:

dbpath=/opt/mongodb/data/config
logpath = /opt/mongodb/data/config.log
logappend = true
bind_ip=172.17.253.67
port = 20000
fork = true

2.4启动路由节点

在每一台server上都执行

[root@localhost bin]# ./mongos --configdb 172.17.253.217:20000,172.17.253.67:20000,172.17.253.216:20000 -port 30000 -chunkSize 5 -logpath /opt/mongodb/data/mongos.log -logappend -fork
about to fork child process, waiting until server is ready for connections.
forked process: 26210
all output going to: /opt/mongodb/data/mongos.log
child process started successfully, parent exiting

2.5配置Sharding

连接到其中一个mongos进程，并切换到admin数据库做以下配置
1. 连接到mongs，并切换到admin
./mongo 172.17.253.217:30000/admin这里必须连接路由节点

>db
Admin
2. 加入shards
如里shard是单台服务器，用>db.runCommand( { addshard : “[:]” } )这样的命令加入，如果shard是replica sets，用replicaSetName/[:port][,serverhostname2[:port],…]这样的格式表示，例如本例执行：

mongos> db.runCommand( { addshard : "shard1/172.17.253.216:27017,172.17.253.67:27017,172.17.253.217:27017",name:"shard1",maxsize:20480});
{ "shardAdded" : "shard1", "ok" : 1 }

mongos> db.runCommand( { addshard : "shard2/172.17.253.217:27018",name:"shard2",maxsize:20480});
{ "shardAdded" : "shard2", "ok" : 1 }

mongos> db.runCommand({listshards:1})
{
	"shards" : [
		{
			"_id" : "shar
