我当前正在运行一个MongoDB副本集,该副本集具有1个主要,1个辅助和1个仲裁器,所有副本都托管在AWS EC2实例上。我最近关闭了辅助服务器以升级硬件。重新启动后,它具有另一个IP地址(如预期)。
重新启动后,我在辅助服务器上重新启动了knex.transaction(function(trx) {
return Promise.map(array, function(item) {
return trx.insert(item).into('table')
.then(returnedFields => {
try{
//do some validation/operation and return the result or the returnedFields themselves as input in the next loop.
/* START Testing a case of rejection */
if (array.indexOf(item) === 3) {
//uncomment the code below to test
//throw new Error('BreakException');
}
/* END */
}catch(err){
fail=true;
}
}).then(val => {
if (fail) {
trx.rollback()//you can ignore this as is automatically triggered here - tested
return Promise.reject(new Error('Rejected'))
}
return val
})
.catch(err => {
fail = true
trx.rollback()//you can ignore this as is automatically triggered here - tested
return Promise.reject(new Error('Rejected'))
});
});
})
.then(function(inserts) {
console.log(inserts.length + 'Items saved.');
})
.catch(function(error) {
console.error(error);
})
并更新了DNS,以便mongo2。**************。com现在指向新的IP地址。
我能够从初级连接到次级
mongod
在次要对象之间或从次要对象相同。
但是,当我在连接到副本集的同时执行mongo1.**************.com:~$ curl -ik mongo2.**************.com:27017
HTTP/1.0 200 OK
Connection: close
Content-Type: text/plain
Content-Length: 84
It looks like you are trying to access MongoDB over HTTP on the native driver port.
时,我与辅助服务器的连接出错。
rs.status()
当通过Robo 3T连接到副本集时,这里是{

我能够通过Robo 3T与辅助服务器建立直接连接。
在主节点的日志中,看到以下错误:

如何获取副本集以连接到辅助副本?
