启动三台机器上的configsvr和mongos节点
[mongodb@node1 logs]$ mongod -f /data/config/configsvr.conf about to fork child process, waiting until server is ready for connections. forked process: 6317 child process started successfully, parent exiting
[mongodb@node1 logs]$ mongos -f /data/config/mongos.conf about to fork child process, waiting until server is ready for connections. forked process: 6345 child process started successfully, parent exiting
查看端口是否启动:
[mongodb@elk_node1 ~]$ ss -atunlp|grep mong
tcp LISTEN 0 128 *:10001 *:* users:(("mongod",2630,6))
tcp LISTEN 0 128 *:10002 *:* users:(("mongod",2654,6))

tcp LISTEN 0 128 *:10005 *:* users:(("mongos",3157,21))配置shard分片
在node1机器上配置shard分片
[mongodb@node1 config]$ mongo --port 10005 MongoDB shell version: 3.2.3 connecting to: 127.0.0.1:10005/test mongos> use admin switched to db admin
mongos> db.runCommand({addshard:"shard1_zxl/192.168.42.41:10001,192.168.42.42:10001,192.168.42.43:10001"});
{ "shardAdded" : "shard1_zxl", "ok" : 1 }mongos> db.runCommand({addshard:"shard2_zxl/192.168.42.41:10002,192.168.42.42:10002,192.168.42.43:10002"});
{ "shardAdded" : "shard2_zxl", "ok" : 1 }mongos> db.runCommand({addshard:"shard3_zxl/192.168.42.41:10003,192.168.42.42:10003,192.168.42.43:10003"});
{ "shardAdded" : "shard3_zxl", "ok" : 1 }查看shard信息
mongos> sh.status()
--- Sharding Status ---
sharding version: {
"_id" : 1,
"minCompatibleVersion" : 5,
"currentVersion" : 6,
"clusterId" : ObjectId("56de6f4176b47beaa9c75e9d")
}
shards:
{ "_id" : "shard1_zxl", "host" : "shard1_zxl/192.168.42.41:10001,192.168.42.42:10001" }
{ "_id" : "shard2_zxl", "host" : "shard2_zxl/192.168.42.42:10002,192.168.42.43:10002" }

active mongoses:
"3.2.3" : 3
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:查看分片状态
mongos> db.runCommand( {listshards : 1 } )
{
"shards" : [
{
"_id" : "shard1_zxl",
"host" : "shard1_zxl/192.168.42.41:10001,192.168.42.42:10001"
},
{
"_id" : "shard2_zxl",
"host" : "shard2_zxl/192.168.42.42:10002,192.168.42.43:10002"
},
{
"_id" : "shard3_zxl",
"host" : "shard3_zxl/192.168.42.41:10003,192.168.42.43:10003"
}
],
"ok" : 1
}启用shard分片的库名字为‘zxl‘,即为库
mongos> sh.enableSharding("zxl")
{ "ok" : 1 }设置集合的名字以及字段,默认自动建立索引,zxl库,haha集合
mongos> sh.shardCollection("zxl.haha",{age: 1, name: 1})
{ "collectionsharded" : "zxl.haha", "ok" : 1 }模拟在haha集合中插入10000数据
mongos> for (i=1;i<=10000;i++) db.haha.insert({name: "user"+i, age: (i%150)})
WriteResult({ "nInserted" : 1 })可以使用上面mongos> sh.status()命令查看各个shard分片情况,以上就是复制集和shard分片搭建完成。
结果如下:
mongos> sh.status()
