<p>maybe it works when you change
rpcallowip=*
to
rpcallowip=127.0.0.1</p>

<p>I found I had to copy the contents of <code>~/.bitcoin/bitcoin.conf</code> into <code>/etc/bitcoin/bitcoin.conf</code> because that's what's being used when bitcoind starts on boot up. I put my user and password in that file, rebooted, and <code>bitcoin-cli</code> worked again.</p>

<p>Also try adding</p>

<pre><code>bitcoin-cli -stdinrpcpass getblockchaininfo -rpcuser user -rpcpassword password
</code></pre>

Do you want to run testnet or mainnet? 18332 is the testnet port. 8332 is mainnet. You have `testnet=0` which maybe should be `testnet=1`?

first of all i tried testnet, but it didn't work the same. You know, i solved the problem, but with not finally correct method. I used command: bitcoind --daemon -rpcuser=user -rpcpassword=password -txindex -rpcallowip=127.0.0.1 -rpcallowip=185.50.25.17 -rpcport=8332. It works, but i don't think this method is ok.

<p>I installed bitoind and synced it. But when i'm trying to connect from my php website i getting: 
Unable to connect to <a href="http://user:password@my.bitoind.server.ip:18332/" rel="nofollow noreferrer">http://user:password@my.bitoind.server.ip:18332/</a>. 
Also when i'm trying to see password through command</p>

<p><code>bitcoin-cli -stdinrpcpass getblockchaininfo</code> </p>

<p>it returns </p>

<p><code>could not locate RPC credentials. No authentication cookie could be found, and RPC password is not set.  See -rpcpassword and -stdinrpcpass.  Configuration file: (/blockchain/.bitcoin/bitcoin.conf)</code>. </p>

<p>My bitcoin.conf file is setted and works nice</p>

<pre><code>rpcuser=USER

testnet=0

maybe it works when you change
rpcallowip=\*
to
rpcallowip=127.0.0.1
