mongodb-sharding-replicate sets

3台机器，3个复制集（shard1，shard2，shard3），3个shards ，3个config servers，3个mongos

机器：
192.168.1.158
192.168.1.224
192.168.1.78
-------------------------------------------------------------------------------
先建目录（192.168.1.158）
/data/servers/sharding/shard1-1、/data/servers/sharding/shard2-1、/data/servers/sharding/shard3-1、/data/servers/sharding/config

192.168.1.224
/data/servers/sharding/shard1-2、/data/servers/sharding/shard2-2、/data/servers/sharding/shard3-2、/data/servers/sharding/config

192.168.1.78
/data/servers/sharding/shard1-3、/data/servers/sharding/shard2-3、/data/servers/sharding/shard3-3、/data/servers/sharding/config
----------------------------------------------------------------------------
分别在3台机器上启动复制集shard1：
192.168.1.158
bin/mongod --shardsvr --replSet shard1 --dbpath /data/servers/sharding/shard1-1 --logpath /data/servers/sharding/shard1.log --port 28011  --logappend --oplogSize 100 --fork
192.168.1.224
bin/mongod --shardsvr --replSet shard1 --dbpath /data/servers/sharding/shard1-2 --logpath /data/servers/sharding/shard1.log --port 28011  --logappend --oplogSize 100 --fork
192.168.1.78
bin/mongod --shardsvr --replSet shard1 --dbpath /data/servers/sharding/shard1-3 --logpath /data/servers/sharding/shard1.log --port 28011  --logappend --oplogSize 100 --fork
用 mongo 连接其中一台机器的 28011端口的 mongod,初始化 Replica Sets“shard1”,执行:
bin/mongo  --port 28011
> use admin
>config = {_id:'shard1',members:[ {_id:0,host:'192.168.1.158:28011'}, {_id:1,host:'192.168.1.224:28011'}, {_id:2,host:'192.168.1.78:28011'}]}
>rs.initiate(config)
----------------------------------------------------------
分别在3台机器上启动复制集shard2：
192.168.1.158
bin/mongod --shardsvr --replSet shard2 --dbpath /data/servers/sharding/shard2-1 --logpath /data/servers/sharding/shard2.log --port 28022  --logappend --oplogSize 100 --fork
192.168.1.224
bin/mongod --shardsvr --replSet shard2 --dbpath /data/servers/sharding/shard2-2 --logpath /data/servers/sharding/shard2.log --port 28022  --logappend --oplogSize 100 --fork
192.168.1.78
bin/mongod --shardsvr --replSet shard2 --dbpath /data/servers/sharding/shard2-3 --logpath /data/servers/sharding/shard2.log --port 28022  --logappend --oplogSize 100 --fork
用 mongo 连接其中一台机器的 28022端口的 mongod,初始化 Replica Sets“shard1”,执行:
bin/mongo --port 28022
> use admin
>config = {_id:'shard2',members:[ {_id:0,host:'192.168.1.158:28022'}, {_id:1,host:'192.168.1.224:28022'}, {_id:2,host:'192.168.1.78:28022'}]}
>rs.initiate(config)
------------------------------------------------------------
分别在3台机器上启动复制集shard3：
192.168.1.158
bin/mongod --shardsvr --replSet shard3 --dbpath /data/servers/sharding/shard3-1 --logpath /data/servers/sharding/shard3.log --port 28033  --logappend --oplogSize 100 --fork
192.168.1.224
bin/mongod --shardsvr --replSet shard3 --dbpath /data/servers/sharding/shard3-2 --logpath /data/servers/sharding/shard3.log --port 28033  --logappend --oplogSize 100 --fork
192.168.1.78
bin/mongod --shardsvr --replSet shard3 --dbpath /data/servers/sharding/shard3-3 --logpath /data/servers/sharding/shard3.log --port 28033  --logappend --oplogSize 100 --fork
用 mongo 连接其中一台机器的 28033端口的 mongod,初始化 Replica Sets“shard1”,执行:
bin/mongo --port 28033
> use admin
>config = {_id:'shard3',members:[ {_id:0,host:'192.168.1.158:28033'}, {_id:1,host:'192.168.1.224:28033'}, {_id:2,host:'192.168.1.78:28033'}]}
>rs.initiate(config)

------------------------------------------------------------------------------------------------------------
分别在3台机器上启动config server
bin/mongod --configsvr --dbpath /data/servers/sharding/config --port 20000 --logpath /data/servers/sharding/config.log  --logappend  --fork
（操作的时候误把--configsvr 写成 --shardsvr ，不知道后果会怎么样。。。）
---------------------------------------------------------------------------------------------------------------------
配置 3 台 Route Process, 分别在3台机器上启动mongos
bin/mongos --configdb 192.168.1.158:20000,192.168.1.224:20000,192.168.1.78:20000  --port 30000 --logpath /data/servers/sharding/mongos.log  --logappend  --fork
----------------------------------------------------------------------------------------------------------
配置 shard cluster ，连接到其中一台机器的端口 30000 的 mongos 进程,并切换到 admin 数据库做以下配置 （这样也行：sh.addShard("shard1/192.168.1.158:28011") 版本2.2前是用下面这种方式，要有三个host）
bin/mongo  --port 3000
>use admin
mongos>db.runCommand({addshard:"shard1/192.168.1.158:28011,192.168.1.224:28011,192.168.1.78:28011"});
{ "shardAdded" : "shard1", "ok" : 1 }
mongos>db.runCommand({addshard:"shard2/192.168.1.158:28022,192.168.1.224:28022,192.168.1.78:28022"});
{ "shardAdded" : "shard2", "ok" : 1 }
mongos>db.runCommand({addshard:"shard3/192.168.1.158:28033,192.168.1.224:28033,192.168.1.78:28033"});
{ "shardAdded" : "shard3", "ok" : 1 }
