mongodb - 创建副本集时出错 - MongoDb

Question

我正在尝试创建副本，但无法继续

创建 3 个 mongod 实例的脚本:

sudo mkdir -p /data/rs1 /data/rs2 /data/rs3

sudo mongod --replSet rs1 --logpath "1.log" --dbpath /data/rs1 --port 27017 --fork
sudo  mongod --replSet rs2 --logpath "2.log" --dbpath /data/rs2 --port 27018 --fork
sudo mongod --replSet rs3 --logpath "3.log" --dbpath /data/rs3 --port 27019 --fork

此操作成功执行，但在此之后我尝试通过以下脚本提供有关 rs2 和 rs3 的 rs1 信息:

init_replica.js:

config = {
            _id:"rs1",members:[
            {_id:0,host:"grit-lenevo-pc:27017",priority:0,slaveDelay:5},
            {_id:1,host:"grit-lenevo-pc:27018"},
            {_id:2,host:"grit-lenevo-pc:27019"}]
}

rs.initiate(config) 
rs.status()

现在当我尝试运行时:

mongo --port 27018 < init_replica.js

我得到:

MongoDB shell version: 3.2.8
connecting to: 127.0.0.1:27018/test
{
    "_id" : "rs1",
    "members" : [
        {
            "_id" : 0,
            "host" : "grit-lenevo-pc:27017",
            "priority" : 0,
            "slaveDelay" : 5
        },
        {
            "_id" : 1,
            "host" : "grit-lenevo-pc:27018"
        },
        {
            "_id" : 2,
            "host" : "grit-lenevo-pc:27019"
        }
    ]
}
{
    "ok" : 0,
    "errmsg" : "Attempting to initiate a replica set with name rs1, but command line reports rs2; rejecting",
    "code" : 93
}
{
    "info" : "run rs.initiate(...) if not yet done for the set",
    "ok" : 0,
    "errmsg" : "no replset config has been received",
    "code" : 94
}
bye

注意:如果我尝试以下命令，相同的命令可以正常工作:

mongo --port 27017 < init_replica.js

Answer 1

就在那里:

"Attempting to initiate a replica set with name rs1, but command line reports rs2; rejecting"

您应该为所有成员提供与种子相同的副本集名称 ( s1 )。对于第二个成员:

sudo mongod --replSet rs1 ...

而不是

sudo mongod --replSet rs2 ...

第三位成员采用相同的原则
