I am running bitcoin-d (probably downloading the prev blocks) in a shell.
In another shell i am trying to get the information of a transaction (0627052b6f28912f2703066a912ea577f2ce4da4caa5a5fbd8a57286c345c2f2) with bitcoin-cli. I can see that tx on blockchain.info but when i tried it with gettransaction and getrawtransaction it didn't work out. Does anyone know why is that?

gettransaction is a wallet RPC. It only works for transactions your wallet knows about. Presumably this is not the case for a transaction from 2013.
getrawtransaction is a node RPC. It works for all transactions, but needs help to find them. One possibility is to enable the transaction index (put txindex=1 in bitcoin.conf, or -txindex on the bitcoind command line). Another option is specifying which block the transaction is in.
There are 2 files : bitcoin.conf and bitcoind.conf. In bitcoin.conf: it is all comments. Is that the right file that i should edit? In some part it writes:
Should i add the line there? – Efe Cini – 2019-09-23T16:57:35.890

For the answer to this comment
Can you give one example of how to do this in cmd as Pieter said : -txindex on the bitcoind command line
I do an example for my configuration bitcoin core, I using the -txindex
the command for run bitcoin
bitcoind -txindex
The essential bitcoin.conf configurations
##
## bitcoin.conf configuration file. Lines beginning with # are comments.
##
server=1
rpcuser=YOUR_USER
rpcpassword=YOUR_PAS
the process bitcoind with the -txindex is longer because bitcoind indexes all block inside the DB, an example, I used an external HDD and in my cases, the process worked for one day
also when the bitcoind has finished you can run your command, so
bitcoin-cli getrawtransaction 0627052b6f28912f2703066a912ea577f2ce4da4caa5a5fbd8a57286c345c2f2
You will have this result

Try to call the command
– vincenzopalazzo – 2019-09-23T16:25:51.743getrawtransactionthis is documentation reference if not work, can you public a minimal example for trying the same command?It says like that: Efe-MacBook-Pro:bitcoin efecini$ bitcoin-cli getrawtransaction 0627052b6f28912f2703066a912ea577f2ce4da4caa5a5fbd8a57286c345c2f2 error code: -5 error message: No such mempool transaction. Use -txindex to enable blockchain transaction queries. Use gettransaction for wallet transactions. – Efe Cini – 2019-09-23T16:51:29.130
with the command getrawtransaction the your code worked follow pieter's instructions – vincenzopalazzo – 2019-09-23T16:57:29.687
I restarted the os and typed bitcoind '-txindex=1' And also add a newline 'txindex=1' in bitcoin.conf.(Also i cant find bitcoin.conf file after i changed it :( ) But stil i get : error code: -5 error message: No such mempool or blockchain transaction. Use gettransaction for wallet transactions. – Efe Cini – 2019-09-23T22:10:21.837
if you run the bitcoind with the --daemon it appare ok but with the -txindex=1 the bitcoin core the blockchain is rescanned so you attend the time for complete the process, it should be the problem. for the bitcoin.conf disappeared, only you can know what dark has happened :) – vincenzopalazzo – 2019-09-23T22:21:38.197
One last thing : Can you give one example how to do this in cmd like Pieter said : -txindex on the bitcoind command line – Efe Cini – 2019-09-23T22:37:49.127
