[英]Mongodb Sharding - no such command: 'addShard'
I'm trying to configure sharding in one machine and I keep getting an error message when trying to add shards. 我正在尝试在一台计算机上配置分片,并在尝试添加分片时不断收到错误消息。 I'm using the following website as a reference: http://www.javahotchocolate.com/notes/mongodb-sharding.html
我使用以下网站作为参考: http : //www.javahotchocolate.com/notes/mongodb-sharding.html
I'm using a single machine and using different ports to simulate the different IPs. 我正在使用一台机器并使用不同的端口来模拟不同的IP。
I have a configuration as follows: 我的配置如下:
Replica set members: 副本集成员:
mongod --dbpath \rs1_p\db --port 27017 --replSet rs1
mongod --dbpath \rs1_s1\db --port 27018 --replSet rs1
mongod --dbpath \rs1_s2\db --port 27019 --replSet rs1
mongod --dbpath \rs1_p\db --port 47017 --replSet rs2
mongod --dbpath \rs1_s1\db --port 47018 --replSet rs2
mongod --dbpath \rs1_s2\db --port 47019 --replSet rs2
Configuring replica sets in MongoDB shell: 在MongoDB shell中配置副本集:
config =
{
_id:"rs1",
members:
[
{ _id:0, host:"computerName:27017" },
{ _id:1, host:"computerName:27018" },
{ _id:2, host:"computerName:27019" }
]
}
rs.initiate( config )
config =
{
_id:"rs2",
members:
[
{ _id:0, host:"computerName:47017" },
{ _id:1, host:"computerName:47018" },
{ _id:2, host:"computerName:47019" }
]
}
rs.initiate( config )
Launching configuration servers: 启动配置服务器:
mongod --dbpath \c1\db --configsvr --port 37017
mongod --dbpath \c2\db --configsvr --port 37018
mongod --dbpath \c3\db --configsvr --port 37019
Launching sharding routers: 启动分片路由器:
mongos --port 27077 --configdb computerName:37017, computerName:37018, computerName:37019
mongos --port 27078 --configdb computerName:37017, computerName:37018, computerName:37019
All okay until here, but In getting an error message in the next step 一切都好,直到这里,但在下一步收到错误信息
sh.addShard('rs1/computerName:27017')
I'm getting the follow error: 我收到了以下错误:
{
"ok" : 0.0,
"errmsg" : "no such command: 'addShard', bad cmd: '{ addShard: \"rs1/computerName:27017\" }'",
"code" : 59
}
I can not seem to get around from this error message. 我似乎无法解决此错误消息。
Any ideas on what am I missing. 关于我缺少什么的任何想法。
Thanks 谢谢
as per documentation 根据文件
Run addShard when connected to a mongos instance.
连接到mongos实例时运行addShard。 The command takes the following form when adding a single database instance as a shard
将单个数据库实例添加为分片时,该命令采用以下形式
when you run this connected to mongo shell you will get that error, so you need to connect to let say mongo --port 27078
and issue that command. 当你运行这个连接到mongo shell时你会得到那个错误,所以你需要连接让我们说
mongo --port 27078
并发出该命令。
mongo --host <hostname of machine running mongos> --port <port mongos listens on>
