部署配置服务器：configsvr

先生成.conf文件

mkdir -p /data/mongodb/configsvr
vim /data/mongodb/configsvr/configsvr.conf
 
systemLog:
  destination: file
  logAppend: true
  path: /data/mongodb/configsvr/configsvr.log
storage:
  dbPath: /data/mongodb/configsvr
  journal:
    enabled: true
processManagement:
  fork: true
net:
  port: 27018
  bindIp: 0.0.0.0
replication:
  replSetName: myconfig
sharding:
  clusterRole: configsvr

启动服务： mongod -f /data/mongodb/configsvr/configsvr.conf

配置副本集：

mongosh 127.0.0.1:27018
use admin
config = { _id:"myconfig", 
  configsvr: true,
  members:[
    {_id:0,host:"192.168.11.137:27018"},
    {_id:1,host:"192.168.11.200:27018"}
  ]
}
rs.initiate(config)
 
rs.status()

部署数据分片服务器：

副本名称：shard1

mkdir -p /data/mongodb/shardsvr1
vim /data/mongodb/shardsvr1/shardsvr.conf
 
systemLog:
  destination: file
  logAppend: true
  path: /data/mongodb/shardsvr1/shardsvr.log
storage:
  dbPath: /data/mongodb/shardsvr1/
  journal:
    enabled: true
processManagement:
  fork: true
net:
  port: 27017
  bindIp: 0.0.0.0
replication:
  replSetName: shard1
sharding:
  clusterRole: shardsvr

配置数据副本集：

mongosh 127.0.0.1:27017
use admin
config = { _id:"shard1", 
  members:[
    {_id:0,host:"192.168.11.137:27017"},
    {_id:1,host:"192.168.11.200:27017"}
  ]
}
rs.initiate(config)
 
rs.status()

部署Router (mongos)服务器：

mkdir -p /data/mongodb/router
vim /data/mongodb/router/router.conf
 
systemLog:
  destination: file
  logAppend: true
  path: /data/mongodb/router/router.log
processManagement:
  fork: true
net:
  port: 27019
  bindIp: 0.0.0.0
sharding:
  configDB: myconfig/192.168.11.137:27018,192.168.11.200:27018

启动命令：mongos -f /data/mongodb/router/router.conf

为了高可用，你可以在另一台机器，再启动一个router实例（router开启多个实例，是不需要组成副本集的）

mongosh 127.0.0.1:27019
use admin
sh.addShard("shard1/192.168.11.137:27017,192.168.11.200:27017")
sh.status()

sh.addShard 把副本集分片，添加到mongos当中

开启数据库分片功能：

sh.enableSharding("MyTestDB")

对集合进行分片初始化：

sh.shardCollection("MyTestDB.UserInfo" , {_id: 'hashed'})  //用哈希算法进行分片

.net连接router：

var client = new MongoClient("mongodb://router1IP:port,router2IP:port");
