I am using bitcoin.rpc.RawProxy to connect to bitcoind and scrape the data. But I am getting an error when I gettransaction and I have to reindex the blockchain. Thus I am wondering how I set the txindex to 1 so I can reindex and continue.

You can enable the txindex by either adding it to your bitcoin.conf file:

txindex=1

or

You can run bitcoind with the -txindex flag:

$ bitcoind -txindex

See:

$ bitcoind --help

    -txindex
       Maintain a full transaction index, used by the getrawtransaction rpc
       call (default: 0)
  • but reindexing is necessary correct? – SantiClaus Nov 18 '18 at 6:08
  • Yes you might need to also use the -reindex flag. You might also want to set a higher -dbcache to speed it up. – JBaczuk Nov 18 '18 at 16:19
  • One more question, and thanks again. If I do not shut out of the ubuntu command prompt correctly, for example if I have to restart it or if it shuts down unexpectedly, can it corrupt the data? – SantiClaus Nov 18 '18 at 17:36
  • And will I know if the database is corrupted? For example, will the program notify me? – SantiClaus Nov 18 '18 at 18:07
  • If you set the -daemon flag it will run in the background and you can close the terminal. If it shuts down, it may corrupt the data, but you should see errors in ~/.bitcoin/debug.log – JBaczuk Nov 18 '18 at 18:16
