[英]Mongodb and node Getting error while connecting with cluster?
我正在嘗試使用我的節點應用程序連接 mongoldb 集群。 我有 mongodb 版本 3.1.0。
我從 mongodb 復制了連接字符串,如下所示。
mongodb://username:<PASSWORD>@clusterstring,clusterstring1,clusterstring2/dbname?ssl=true&replicaSet=replicaSet&authSource=admin&retryWrites=true
但是,當我嘗試使用上述字符串進行連接時,出現以下錯誤。
MongoError: seed list contains no mongos proxies, replicaset connections requires the parameter replicaSet to be supplied in the URI o r options object, mongodb://server:port/db?replicaSet=name
所以上面的消息給了我兩個錯誤
如果我設置 ssl=false,則第二條消息消失而第一條消息保持不變。
知道我做錯了什么嗎?
如果您想知道我如何在我的應用程序中進行連接,
this is in config
module.exports = {
secret: 'sectreKey',
session: { session: false },
database: aboveconnectionstring
}
//the above values are passed here
module.exports = (mongoose, config) => {
const database = mongoose.connection;
mongoose.Promise = Promise;
mongoose.connect(config.database, {
promiseLibrary: global.Promise,
useNewUrlParser: true
});
database.on('error', error => console.log(`Connection to sample service database failed: ${error}`));
database.on('connected', () => console.log('Connected to sample Service database'));
database.on('disconnected', () => console.log('Disconnected from sample Service database'));
process.on('SIGINT', () => {
database.close(() => {
console.log('sampleVueService terminated, connection closed');
process.exit(0);
})
});
};
編輯:已解決
我從下面的堆棧溢出問題中找到了答案。 Mongoose 集群與 Mongo 連接。但它不與參數 &retryWrites=true 連接。 所以我去掉了參數,連接成功。
MongoError:字段“retryWrites”對於索引規范無效。 規范:{ name: "username_1", key: { username: 1 }, unique: true, background: true, retryWrites: true }
所以我的新數據庫連接如下所示
module.exports = (mongoose, config) => {
if(config.database.indexOf('replicaSet') > - 1) {
dbOptions = {
db: {native_parser: true},
replset: {
auto_reconnect:false,
poolSize: 10,
socketOptions: {
keepAlive: 1000,
connectTimeoutMS: 30000
}
},
server: {
poolSize: 5,
socketOptions: {
keepAlive: 1000,
connectTimeoutMS: 30000
}
}
};
}
const database = mongoose.connection;
mongoose.Promise = Promise;
mongoose.connect(config.database, dbOptions);
database.on('error', error => console.log(`Connection to sample service database failed: ${error}`));
database.on('connected', () => console.log('Connected to sample Service database'));
database.on('disconnected', () => console.log('Disconnected from sample Service database'));
process.on('SIGINT', () => {
database.close(() => {
console.log('sampleVueService terminated, connection closed');
process.exit(0);
})
});
};
希望它也能幫助其他人。
錯誤可能是由於mongoose和mongodb的版本,嘗試運行npm update或npx update ,更新包解決了錯誤
