我在我的debian机器上设置了如下配置的mongodb 3.2集群
# Config Server - mongod.conf
storage:
dbPath: /data/mongodb
journal:
enabled: true
systemLog:
destination: file
logAppend: true
path: /var/log/mongodb/mongod.log
net:
port: 27019
bindIp: 0.0.0.0
replication:
replSetName: rs0
sharding:
clusterRole: "configsvr"
# Shard Server 1 - mongod.conf
storage:
dbPath: /data/mongodb
journal:
enabled: true
systemLog:
destination: file
logAppend: true
path: /var/log/mongodb/mongod.log
net:
port: 27017
bindIp: 0.0.0.0
replication:
replSetName: rs0
# Shard Server 2 - mongod.conf
storage:
dbPath: /data/mongodb
journal:
enabled: true
systemLog:
destination: file
logAppend: true
path: /var/log/mongodb/mongod.log
net:
port: 27017
bindIp: 0.0.0.0
replication:
replSetName: rs0
并运行mongos在查询路由器服务器上添加分片
$)mongos --configdb mongo-config:27019
但我无法添加碎片。
mongos> sh.addShard("rs0/mongo-db1:27017")
{
"ok" : 0,
"errmsg" : "Cannot add rs0/mongo-db1:27017 as a shard since it is part of a config server replica set",
"code" : 96
}
mongos> sh.addShard("rs0/mongo-db1:27017")
{
"ok" : 0,
"errmsg" : "Surprised to discover that mongo-db1:27017 does not believe it is a config server",
"code" : 72
}
getSharmap Command。
mongos> db.runCommand("getShardMap");
{
"map" : {
"config" : "rs0/mongo-db1:27017,mongo-db2:27017",
"mongo-db1:27017" : "rs0/mongo-db1:27017,mongo-db2:27017",
"mongo-db2:27017" : "rs0/mongo-db1:27017,mongo-db2:27017",
"rs0/mongo-config:27019" : "rs0/mongo-config:27019",
"rs0/mongo-db1:27017,mongo-db2:27017" : "rs0/mongo-db1:27017,mongo-db2:27017"
},
"ok" : 1
}
这里是mongos log
2016-04-06T15:05:14.243 + 0000 I SHARDING [Balancer]即将元数据事件记录到动作日志中:{_ id:" mongo-router1-2016-04-06T15:05:14.243 + 0000- 570525aa6b2b3378bb9daf56",服务器:" mongo-router1",clientAddr:"",时间:新日期(1459955114243),什么:" balancer.round", ns:"",详细信息:{executionTimeMillis:3,errorOccured:true,errmsg:"无法从配置服务器获取更新的分片列表,因为惊讶地发现mongo-db1:27017没有相信它是一个配置服务器" }}
我错过了什么。?
答案 0 :(得分:0)
由于您尝试添加的分片是在rs0副本集中,并且由于rs0保留了您的配置服务器,因此它不会让您创建分片。尝试将其添加到不同的副本集,如rs1,这应该工作。
