docker run --name mongo -v /mongodb/mongodb:/data/db -v /etc/localtime:/etc/localtime:ro  -p 27017:27017 --restart=always -d mongo

docker inspect mongo | grep IPAddress docker exec -it mongo bash mongo --host 172.17.0.3 --port 27017  docker pull mongo:4.0.0

1、创建配置服务复制集

docker run -d --name configsvr0 -v /home/mongodb/data/cs/configsvr0:/data/configdb mongo --configsvr --replSet "rs_configsvr" --bind_ip_all docker run -d --name configsvr1 -v /home/mongodb/data/cs/configsvr1:/data/configdb mongo --configsvr --replSet "rs_configsvr" --bind_ip_all docker run -d --name configsvr2 -v /home/mongodb/data/cs/configsvr2:/data/configdb mongo --configsvr --replSet  "rs_configsvr" --bind_ip_all  docker inspect configsvr0 | grep IPAddress docker inspect configsvr1 | grep IPAddress docker inspect configsvr2 | grep IPAddress  docker exec -it configsvr0 bash

mongo --host 172.17.0.7 --port 27019 rs.initiate( {     _id: "rs_configsvr",     configsvr: true,     members: [         { _id : 0, host : "172.17.0.3:27019" },         { _id : 1, host : "172.17.0.4:27019" },         { _id : 2, host : "172.17.0.7:27019" }     ] }) 

2、创建分片复制集

docker run --name shardsvr00 -d -v /home/mongodb/data/sh/shardsvr00:/data/db mongo --shardsvr --replSet "rs_shardsvr0" --bind_ip_all docker run --name shardsvr01 -d -v /home/mongodb/data/sh/shardsvr01:/data/db mongo --shardsvr --replSet "rs_shardsvr0" --bind_ip_all docker run --name shardsvr02 -d -v /home/mongodb/data/sh/shardsvr02:/data/db mongo --shardsvr --replSet "rs_shardsvr0" --bind_ip_all docker run --name shardsvr10 -d -v /home/mongodb/data/sh/shardsvr10:/data/db mongo --shardsvr --replSet "rs_shardsvr1" --bind_ip_all docker run --name shardsvr11 -d -v /home/mongodb/data/sh/shardsvr11:/data/db mongo --shardsvr --replSet "rs_shardsvr1" --bind_ip_all docker run --name shardsvr12 -d -v /home/mongodb/data/sh/shardsvr12:/data/db mongo --shardsvr --replSet "rs_shardsvr1" --bind_ip_all  docker inspect shardsvr00 | grep IPAddress docker inspect shardsvr01 | grep IPAddress docker inspect shardsvr02 | grep IPAddress  docker exec -it shardsvr00 bash mongo --host 172.17.0.8 --port 27018 rs.initiate( {     _id : "rs_shardsvr0",     members: [         { _id : 0, host : "172.17.0.8:27018" },         { _id : 1, host : "172.17.0.9:27018" },         { _id : 2, host : "172.17.0.10:27018" }     ] })  docker inspect shardsvr10 | grep IPAddress docker inspect shardsvr11 | grep IPAddress docker inspect shardsvr12 | grep IPAddress  docker exec -it shardsvr10 bash mongo --host 172.17.0.11 --port 27018 rs.initiate( {     _id : "rs_shardsvr1",     members: [         { _id : 0, host : "172.17.0.11:27018" },         { _id : 1, host : "172.17.0.14:27018" },         { _id : 2, host : "172.17.0.15:27018" }     ] })

3、创建mongos，连接mongos到分片集群

docker run --name mongos0 -d  -p 27017:27017 --entrypoint "mongos" mongo  --configdb rs_configsvr/172.17.0.3:27019,172.17.0.4:27019,172.17.0.7:27019 --bind_ip_all

4、添加分片到集群

docker inspect mongos0 | grep IPAddress docker exec -it mongos0 bash mongo --host 172.17.0.16 --port 27017  sh.addShard("rs_shardsvr0/172.17.0.8:27018,172.17.0.9:27018,172.17.0.10:27018") sh.addShard("rs_shardsvr1/172.17.0.11:27018,172.17.0.14:27018,172.17.0.15:27018")

5、数据库 启用 分片

sh.enableSharding("tst99") use tst99 db.tst99.insert({"name":"菜鸟教程5555"})

6、分片集合

# 对 test.order 的 _id 字段进行哈希分片： sh.shardCollection("test.order", {"_id": "hashed" })

7、插入数据

use test for (i = 1; i <= 1001; i=i+1){     db.order.insert({'price': 1}) }

8、查看数据分布

db.order.find().count() #进入 shardsvr0 docker exec -it shardsvr00 bash mongo --host 172.17.0.6 --port 27018 db.order.find().count() 484  #进入 shardsvr1 docker exec -it shardsvr10 bash mongo --host 172.17.0.9 --port 27018 db.order.find().count() 517
