Използваме това:
if(config.db.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
}
}
};
}
var db = mongoose.connect(config.db, dbOptions);
където
config.db = 'mongodb://USER:[email protected]:port1,host2:port2/DBNAME?replicaSet=RSNAME'
Auto_reconnect е изключено съгласно https://team.goodeggs.com/reconnecting-to-mongodb-when-mongoose-connect-fails-at-startup-83ca8496ca02
